Step-by-Step: Cinnamon M&M Oatmeal Cookies

Let’s dive into the baking process with these simple steps:
Step 1: Preheat Your Oven
Preheat your oven to 350°F (175°C). This ensures that your cookies bake evenly.
Step 2: Cream the Butter and Sugars
In a large mixing bowl, combine the softened unsalted butter, light brown sugar, and white sugar. Use an electric mixer to cream them together until the mixture is light and fluffy, about 2-3 minutes.
Step 3: Add Egg and Vanilla
Add the large egg and vanilla extract to the butter and sugar mixture. Beat until fully incorporated.
Step 4: Mix Dry Ingredients
In a separate bowl, whisk together the all-purpose flour, baking powder, baking soda, salt, and cinnamon.
Step 5: Combine Wet and Dry Ingredients
Gradually add the dry ingredients to the wet mixture, mixing on low speed until just combined.
Step 6: Stir in Oats, Cinnamon Chips, and M&M’s
Fold in the old-fashioned oats, cinnamon chips, and Cinnamon M&M’s using a spatula or wooden spoon. Make sure everything is evenly distributed throughout the dough.
Step 7: Scoop and Bake
Using a cookie scoop or tablespoon, drop the dough onto a baking sheet lined with parchment paper, spacing them about 2 inches apart. Bake in the preheated oven for 10-12 minutes or until the edges are lightly golden.
Step 8: Cool the Cookies
Once baked, remove the cookies from the oven and let them cool on the baking sheet for about 5 minutes before transferring them to a wire rack to cool completely.
Adaptations for Special Diets

If you or someone you know has dietary restrictions, here are some adaptations you can make:
- Dairy-Free: Substitute unsalted butter with coconut oil or a dairy-free butter alternative.
- Gluten-Free: Use a 1:1 gluten-free baking blend in place of all-purpose flour.
- Lower Sugar: Reduce the amount of sugar or use a sugar alternative like coconut sugar.
- Vegan: Replace the egg with a flax egg (1 tablespoon flaxseed meal + 2.5 tablespoons water) and use a dairy-free butter.
Method to the Madness
The process of making Cinnamon M&M Oatmeal Cookies is as delightful as the cookies themselves. Here’s a quick rundown of the method:
- Begin by creaming the butter and sugars together to create a light and fluffy mixture.
- Incorporate the egg and vanilla for added richness.
- Whisk together the dry ingredients separately to ensure even distribution.
- Mix everything together, being careful not to overmix, to keep your cookies tender.
- Finish by folding in the oats, cinnamon chips, and M&M’s for a burst of flavor.
- Finally, scoop, bake, and enjoy the heavenly aroma that fills your kitchen!
Cooling, Storing & Rewarming
To ensure your Cinnamon M&M Oatmeal Cookies stay fresh and delicious, follow these tips:
- Cooling: Allow the cookies to cool on a wire rack after baking to prevent them from becoming soggy.
- Storing: Store cookies in an airtight container at room temperature for up to one week.
- Freezing: You can freeze the cookie dough for up to three months. Scoop out individual portions and freeze on a baking sheet before transferring to a bag.
- Rewarming: To enjoy them warm, microwave for 10-15 seconds, or pop them in a preheated oven at 350°F for a few minutes.
Reader Questions
Can I use quick oats instead of old-fashioned oats?
While you can use quick oats, they will yield a different texture. Old-fashioned oats give the cookies a chewier consistency, which is ideal for this recipe.
What can I substitute for cinnamon chips?
If you can’t find cinnamon chips, you can use white chocolate or butterscotch chips instead. You could also add an extra teaspoon of ground cinnamon to enhance the flavor.
How do I know when the cookies are done baking?
The cookies should be lightly golden around the edges but still soft in the center. They will continue to firm up as they cool on the baking sheet.
Can I add nuts to the cookie dough?
Absolutely! Chopped nuts like walnuts or pecans would add a nice crunch and complement the flavors beautifully.
