Why You’ll Fall in Love with These Instant Oatmeal Cookies
We’ve all been there: buying bulk boxes of instant oatmeal packets with the best intentions, only to find them collecting dust at the back of the pantry. My own kids, bless their hearts, are quite particular about their breakfast choices. I once stocked up on two boxes, assuming it would be a hit, but only one of my three little ones showed any interest in oatmeal, and even then, it wasn’t his favorite. Watching those boxes sit, untouched, felt like such a waste!
That’s when I decided it was time to get creative and put those packets to good use. The result? These incredibly delicious cookies made with instant oatmeal packets! And here’s the best part: my picky eaters, including the one who barely tolerated oatmeal for breakfast, absolutely adored them. You’ll love this recipe because it’s:

Pop them into a freezer bag, and you’ll have a ready-made treat for school lunches, unexpected guests, or simply a convenient indulgence whenever the craving strikes.
- Absolutely Delicious: These aren’t just “good for using up leftovers” cookies. They are genuinely soft, delightfully chewy, and infused with a comforting blend of spices that will remind you of classic oatmeal cookies. Each bite offers that perfect balance of sweetness and warmth.
- A Smart Way to Reduce Food Waste: Instead of letting those instant oatmeal packets expire or go to waste, this recipe transforms them into a fantastic new creation. It’s a win-win: a delicious treat for you and your family, and less food ending up in the bin.
The Unexpected Charm of Instant Oatmeal in Cookies
You might be wondering, “Why instant oatmeal, specifically?” The beauty of instant oatmeal packets in this recipe lies in several key factors:
Firstly, instant oats are pre-cooked and finely cut, meaning they absorb moisture much faster than traditional rolled oats. This quick absorption helps create a wonderfully soft and moist cookie texture without requiring additional liquid or extended resting times for the dough. They integrate seamlessly into the batter, ensuring every bite has a delicate oat flavor without being overly fibrous.
Secondly, many instant oatmeal packets come pre-sweetened and flavored (like maple and brown sugar, cinnamon spice, or apples and cinnamon). This convenience means you often need less added sugar and spices, simplifying the ingredient list and adding an extra layer of flavor complexity directly from the packet. It’s like having a built-in flavor booster!
Finally, using instant oatmeal directly from the packet eliminates the need to cook it first, saving you time and effort. It’s truly a grab-and-go ingredient that streamlines the baking process, making these some of the quickest and easiest oatmeal cookies you’ll ever bake.
Key Ingredients for Your Best Instant Oatmeal Cookies

Creating these delightful cookies requires a few simple ingredients, each playing a crucial role in achieving that perfect soft, chewy texture and spiced flavor. Here’s a closer look at what you’ll need and why:
- Unsalted Butter: The foundation of any good cookie, unsalted butter contributes to a rich, tender crumb. Using unsalted butter allows you to control the exact amount of salt in your recipe, preventing your cookies from becoming too salty. Ensure your butter is at room temperature for optimal creaming.
- Brown Sugar: We’re using just ½ cup of brown sugar in this recipe. Brown sugar is key for achieving that signature chewy texture and adds a lovely molasses flavor. Since instant oatmeal packets are often presweetened, this reduced amount helps balance the overall sweetness, ensuring your cookies aren’t overly sugary.
- Egg: A single large egg provides essential structure and acts as a binding agent, holding all the ingredients together and contributing to the cookie’s moistness. Always opt for a large egg in baking unless a recipe specifically calls for a different size.
- Instant Oatmeal Packets: The star of the show! You’ll need three standard instant oatmeal packets. I typically use Quaker’s maple and brown sugar flavor, which adds a fantastic depth of flavor. However, feel free to use any flavor you prefer – cinnamon spice, apples and cinnamon, or even plain instant oats will work wonderfully. The key is using *instant* oats. If using a different brand or bulk instant oats, aim for a total of 129 grams, or approximately 1 ⅓ cups.
- All-Purpose Flour: This provides the necessary structure to your cookies, preventing them from spreading too much and maintaining their shape. Measuring flour correctly (lightly spooned into a cup and leveled off) is crucial for consistent results.
- Baking Soda: Don’t underestimate the power of baking soda! It acts as a leavening agent, creating a beautiful rise and contributing to the perfect soft and slightly airy texture of the cookies. Make sure yours is fresh for the best lift.
- Kosher Salt: A pinch of salt is vital for balancing the sweetness and enhancing all the other flavors in the cookie. If you only have table salt on hand, remember to reduce the amount by half, as table salt is finer and more concentrated.
How to Make Easy Instant Oatmeal Cookies: Step-by-Step Guide
Baking these instant oatmeal cookies is incredibly straightforward and comes together quickly. Follow these simple steps for perfectly soft and chewy results:
- Prepare Your Oven & Pan: First, preheat your oven to 350 degrees Fahrenheit (175°C). Line two baking sheets with parchment paper. This prevents sticking and ensures even baking.
- Cream Butter and Brown Sugar: In a large mixing bowl, or the bowl of a stand mixer fitted with the paddle attachment, combine your room temperature unsalted butter and brown sugar. Beat them together on medium speed for about 2-3 minutes until the mixture is light, fluffy, and noticeably paler in color. This step is crucial as it incorporates air, which is essential for a chewy cookie texture.
- Add the Egg: Crack in the large egg and continue to beat until it’s fully incorporated into the butter and sugar mixture. At this stage, the mixture might look slightly curdled, but don’t worry – this is completely normal and will resolve as you add the dry ingredients. Make sure to scrape down the sides of the bowl to ensure everything is well combined.




- Incorporate Dry Ingredients: Add the contents of your instant oatmeal packets, all-purpose flour, baking soda, and kosher salt to the wet mixture. Beat on low speed until just combined and an oatmeal cookie dough forms. Be careful not to overmix the dough, as overbeating can develop the gluten in the flour too much, leading to dense, tough cookies rather than soft and chewy ones. Stop mixing as soon as no dry streaks of flour remain.
- Scoop the Cookies: Using a small cookie scoop (a 1.5-tablespoon size works well), scoop 8 uniform cookie dough balls onto each parchment-lined sheet pan. Ensure you leave enough space between them, as these cookies will spread slightly while baking. Uniformly sized cookies bake more evenly.




- Bake to Perfection: Place the sheet pans into your preheated oven and bake for 10 to 11 minutes. The cookies are ready when the edges appear lightly golden brown, but the centers still look slightly soft or “underbaked.” Remember, cookies continue to set and firm up as they cool on the baking sheet, so resist the urge to overbake them.
- Cool & Enjoy: Once out of the oven, let the cookies cool on the baking sheets for at least 10 minutes. This crucial cooling time allows them to firm up properly. Hot cookies are very delicate and will fall apart if you try to transfer them too soon. After 10 minutes, you can carefully move them to a wire rack to cool completely. Then, it’s time to enjoy these warm, soft, and chewy delights!

Expert Tips for Baking Your Best Instant Oatmeal Cookies
To ensure your instant oatmeal cookies turn out perfectly every time, keep these expert tips in mind:
- Use a Portion Scoop for Uniformity: I can’t stress this enough – investing in good cookie scoops is a game-changer! Not only do they make scooping dough a breeze, but they also ensure all your cookies are the same size. This leads to even baking and beautiful, consistent results. I recommend having both a small (1.5 tbsp) and a large (3 tbsp) scoop.
- Don’t Overmix the Cookie Dough: This is a golden rule in baking! Just like with cake batter, overmixing cookie dough can lead to excessive gluten development in the flour. This results in cookies that are tough, dense, and prone to spreading too much. Mix until the ingredients are just combined and no dry streaks of flour are visible, then stop.
- Embrace Room Temperature Ingredients: For the best results, ensure your butter and egg are at room temperature. Room temperature butter creams beautifully with sugar, incorporating more air for a lighter, fluffier texture. A cold egg can cause the butter mixture to seize, leading to a lumpy batter.
- Resist the Urge to Overbake: It’s tempting to leave cookies in the oven until they look fully browned, but oatmeal cookies continue to cook and set after they’re removed from the heat. Look for edges that are golden brown and centers that still appear slightly soft or even a little underdone. This guarantees a soft and chewy interior.
- Allow Proper Cooling Time: I know, the aroma of freshly baked cookies is intoxicating! But patience is key. If you try to transfer hot cookies to a cooling rack too soon, they are likely to crumble and fall apart. Let them rest on the baking sheet for at least 10 minutes to firm up before moving them.
- Experiment with Your Favorite Oatmeal Flavors: While I used maple and brown sugar instant oatmeal (because that’s what I had on hand!), this recipe is incredibly versatile. Cinnamon and spice, apples and cinnamon, peaches and cream, or even plain instant oats (you might add a pinch more cinnamon or sugar then) will yield delicious results. Choose your favorite to customize the flavor!
- Always Use Parchment Paper: Lining your baking sheets with parchment paper prevents cookies from sticking, ensures easy cleanup, and helps in even browning on the bottom.

Endless Possibilities: Substitutions & Add-ins
This instant oatmeal cookie recipe is wonderfully adaptable, allowing you to customize it to your dietary needs or flavor preferences:
- Dairy-Free Option: Easily swap the unsalted butter with your favorite vegan buttery sticks or a dairy-free margarine. Many well-stocked grocery stores offer excellent plant-based alternatives that perform beautifully in baking. Ensure your chosen instant oatmeal packets are also dairy-free.
- Delightful Mix-ins: Elevate your cookies with an array of delicious additions. Stir in about ¾ cup of any of these during the final mixing stage:
- Chocolate chips (milk, dark, or semi-sweet)
- White chocolate chips
- Dried cranberries or raisins for a classic touch
- Chopped pecans, walnuts, or almonds for a nutty crunch
- M&M’s for a fun, colorful twist
- Shredded coconut for a tropical flair
- A combination of chocolate chips and dried fruit for extra texture and flavor!
- Gluten-Free Version: To make these cookies gluten-free, substitute the all-purpose flour with a high-quality 1-to-1 gluten-free baking flour blend, such as Bob’s Red Mill’s Gluten Free 1-to-1 Baking Flour (the one in the blue bag works particularly well). Remember to also use certified gluten-free instant oatmeal packets.
- Spice It Up: For an extra layer of warmth, you can add a pinch of ground cinnamon, nutmeg, or even a tiny bit of ginger to your dry ingredients, especially if you’re using plain instant oatmeal or a milder flavor.

Storage & Freezing for Future Enjoyment
Proper storage is key to keeping your instant oatmeal cookies fresh and delicious. Always ensure the cookies have cooled completely before storing them. Packaging warm cookies traps moisture, which can make them soggy and spoil faster.
- Storing Baked Cookies: Place your cooled cookies in an airtight container or a heavy-duty ziplock bag. Store them at room temperature on your counter for up to 3 days. After this time, they tend to dry out and become stale. For an even longer shelf life, you can refrigerate them for up to a week.
- Freezing Baked Cookies: For extended freshness, baked cookies freeze beautifully! Once completely cooled, arrange them in a single layer on a baking sheet and flash freeze for about an hour until solid. Then, transfer the frozen cookies to a freezer-safe ziplock bag or an airtight container, separating layers with parchment paper to prevent sticking. They will keep well in the freezer for up to 3 months. Thaw at room temperature or gently warm in the microwave for a quick treat.
How to Freeze Cookie Dough:
Freezing cookie dough is one of my favorite meal prep hacks! It means fresh-baked cookies are always just 10-15 minutes away, perfect for unexpected cravings or guests. Here’s how:
- Once you’ve made your cookie dough, use a cookie scoop to portion out individual cookie dough balls onto a parchment-lined plate or baking sheet.
- Place the plate or pan with the scooped dough balls into the freezer for at least one hour, or until the dough is firm. This “flash freezing” step prevents the dough balls from sticking together later.
- Once frozen solid, transfer the cookie dough balls to a freezer-safe ziplock bag. Don’t forget to label the bag with the date and baking instructions (bake at 350°F for 12-15 minutes from frozen).
- Since the cookie dough balls are pre-frozen individually, they won’t get squashed or stick together in the bag, making it easy to grab just one or two at a time.
- To Bake from Frozen: Simply place the frozen dough balls on a parchment-lined baking sheet and bake at 350°F (175°C) for 12-15 minutes, adding a few extra minutes to the baking time compared to fresh dough.

Frequently Asked Questions (FAQs) About Instant Oatmeal Cookies
Here are answers to some common questions you might have about making these delicious cookies:
- What kind of instant oatmeal should I use?
You should use standard single-serving instant oatmeal packets. Flavored varieties like maple & brown sugar, cinnamon spice, or apples & cinnamon work exceptionally well, as they add pre-measured sweetness and spice. Plain instant oatmeal can also be used; you might just want to add a little extra cinnamon or a touch more brown sugar to taste. - Can I use old-fashioned (rolled) oats instead of instant oatmeal?
No, it’s not recommended. Old-fashioned oats have a different texture and require more liquid and baking time to soften. They won’t integrate into the cookie dough the same way instant oats do, and your cookies will likely turn out drier and chewier, possibly not spreading correctly. Stick to instant oatmeal for this specific recipe. - Why did my cookies spread too much/not enough?
Cookies spreading too much can be due to over-creaming the butter and sugar, butter being too warm, dough not being chilled (if you opted to chill it), or inaccurate flour measurement (too little flour). If cookies didn’t spread enough, your butter might have been too cold, or you might have used too much flour. - How do I know when the instant oatmeal cookies are done?
Look for edges that are lightly golden brown. The centers should still appear soft and slightly underbaked. They will continue to set as they cool on the baking sheet. Trust me, pulling them out when they look a little soft in the middle is the secret to a perfectly chewy cookie! - Can I add other spices?
Absolutely! A dash of cinnamon is often present in flavored instant oatmeals, but if you want to boost it, or add a pinch of nutmeg, allspice, or ginger, feel free. Start with ¼ teaspoon and adjust to your preference.
