Cook Easy Oatmeal Cookies Like This

Ready to get baking? Follow these simple steps:
Step 1: Preheat Your Oven
Preheat your oven to 350°F (175°C). This ensures that your cookies will bake evenly right from the start.
Step 2: Cream the Butter and Sugar
In a large mixing bowl, beat the room temperature unsalted butter and brown sugar together until the mixture is light and fluffy. This should take about 2-3 minutes.
Step 3: Add the Egg and Vanilla
Crack in the egg and pour in the vanilla extract. Mix until well combined.
Step 4: Combine the Dry Ingredients
In a separate bowl, whisk together the all-purpose flour, baking soda, baking powder, and salt. Gradually add this dry mixture to the wet ingredients, mixing until just combined.
Step 5: Stir in the Oats
Fold in the old-fashioned oats until evenly distributed throughout the dough.
Step 6: Scoop and Bake
Using a cookie scoop or tablespoon, drop rounded balls of dough onto a parchment-lined cookie sheet, leaving enough space between each to allow for spreading. Bake in the preheated oven for 10-12 minutes, or until the edges are lightly golden.
Step 7: Cool and Enjoy
Remove from the oven and let the cookies cool on the baking sheet for 5 minutes before transferring them to a wire rack to cool completely. Enjoy your Easy Oatmeal Cookies warm or at room temperature!
Adaptations for Special Diets

These Easy Oatmeal Cookies can be easily adapted for various dietary needs:
- Dairy-Free: Substitute the unsalted butter with vegan butter or coconut oil.
- Gluten-Free: Use a gluten-free all-purpose flour blend in place of regular flour.
- Vegan: Swap the egg for a flax egg (1 tablespoon flaxseed meal + 2.5 tablespoons water, let sit for 5 minutes) and use dairy-free butter.
- Low Sugar: Use a sugar substitute or reduce the amount of brown sugar to suit your taste.
Notes on Ingredients
Each ingredient plays a vital role in the texture and flavor of your Easy Oatmeal Cookies:
- Unsalted Butter: Using room temperature butter ensures a smooth batter and helps the cookies spread beautifully.
- Brown Sugar: Adds moisture and a rich caramel flavor, contributing to the chewiness of the cookies.
- Old-Fashioned Oats: For the best texture, choose old-fashioned oats rather than quick oats, which can become mushy.
Leftovers & Meal Prep
If you happen to have any Easy Oatmeal Cookies left over (which is rare!), store them in an airtight container at room temperature for up to a week. They also freeze well! Just place them in a single layer in a freezer-safe bag or container, and they can last for up to three months. When you’re ready to enjoy them, simply thaw at room temperature or warm them in the oven for a few minutes to regain that fresh-baked goodness.
Ask the Chef
Can I use instant oats instead of old-fashioned oats?
While you can use instant oats, they will yield a different texture. Old-fashioned oats provide the chewy consistency that makes these cookies so delightful.
What can I add to my oatmeal cookies for extra flavor?
Feel free to add chocolate chips, chopped nuts, raisins, or even coconut flakes for a delicious twist on the classic recipe!
Why are my cookies flat?
If your cookies turn out flat, it could be due to melted butter or not enough flour. Make sure your butter is softened but not melted, and measure your flour accurately.
Can I double this recipe?
Absolutely! This recipe is easily doubled if you’re looking to feed a crowd or want to stock your freezer with delicious cookies.
