Step‑by‑Step Instructions for Peanut Butter M&Ms Cookies
Step 1: Preheat the Oven
Begin by preheating your oven to 350°F (175°C). While the oven is warming up, prepare two baking sheets by lining them with parchment paper. This will ensure that your Peanut Butter M&Ms Cookies have a perfect, non-stick surface as they bake.
Step 2: Cream the Butters and Sugars
In a large mixing bowl, use an electric mixer to cream together ½ cup of softened unsalted butter, ¾ cup of creamy or crunchy peanut butter, ½ cup of brown sugar, and ¼ cup of granulated sugar. Beat them on medium speed until the mixture is light and fluffy, which takes about 2-3 minutes. The combination should be smooth and well-blended.
Step 3: Add Egg and Vanilla
Next, mix in 1 large egg and 1 teaspoon of vanilla extract to the creamed mixture. Continue to beat on medium speed until these ingredients are fully incorporated, which will take about a minute. The batter should look silky and cohesive, creating a rich foundation for your cookies.
Step 4: Combine Dry Ingredients
In a separate bowl, whisk together 1 cup of all-purpose flour, ½ teaspoon of baking soda, and ¼ teaspoon of salt. Ensure there are no lumps and that the dry ingredients are evenly mixed. This step is essential for achieving the right texture in your Peanut Butter M&Ms Cookies.
Step 5: Mix Wet and Dry Ingredients
Gradually add the dry flour mixture to the wet ingredients, mixing on low speed until just combined. Be careful not to overmix; you want the dough to remain soft and slightly sticky. This will create the perfect base for your cookie dough.
Step 6: Fold in M&Ms
Gently fold in ¾ cup of peanut butter M&Ms with a spatula or wooden spoon, leaving a few for topping later. The colorful candies should be evenly distributed throughout the dough, giving the cookies that delightful burst of flavor and sweetness with each bite.
Step 7: Scoop Cookie Dough
Using a cookie scoop or tablespoon, portion out the dough onto your prepared baking sheets, leaving about 2 inches of space between each scoop. Slightly flatten each dough ball with your hand, and don’t forget to press a few extra M&Ms onto the tops of the dough balls for added color and sweetness.
Step 8: Bake the Cookies
Place the baking sheets in the preheated oven and bake the cookies for 10–12 minutes. You’ll know they are done when the edges turn lightly golden, while the centers remain soft. Keep an eye on the time to achieve the perfect balance of softness and chewiness.
Step 9: Cool the Cookies
Once baked, remove the cookies from the oven and let them cool on the baking sheets for 5 minutes. This cooling time allows them to set slightly before you transfer them to a wire rack. You want them to be warm but firm enough to handle.
Step 10: Serve or Store
Finally, transfer the cooled Peanut Butter M&Ms Cookies to a wire rack to cool completely. Serve them warm for the best experience, or store them in an airtight container once fully cooled. These cookies are perfect for sharing or enjoying all to yourself!
How to Store and Freeze Peanut Butter M&Ms Cookies
Room Temperature: Store your cookies in an airtight container at room temperature for up to 5 days to keep them fresh and chewy.
Fridge: If you prefer your cookies a bit firmer, you can refrigerate them in an airtight container for up to 1 week. Just allow them to come to room temperature before enjoying!
Freezer: Freeze your Peanut Butter M&Ms Cookies in a single layer on a baking sheet for 1 hour, then transfer to a freezer-safe bag. They can be kept for up to 3 months, perfect for those late-night cravings!
Reheating: To enjoy warm cookies again, simply microwave them for about 10-15 seconds or place them in a 350°F (175°C) oven for 5 minutes. Enjoy the gooey goodness!

Expert Tips for Peanut Butter M&Ms Cookies
Perfect Butter Consistency: Ensure your butter is softened, not melted. This helps achieve light and fluffy cookies without altering the texture.
Don’t Overmix: When combining the wet and dry ingredients, mix just until incorporated. Overmixing can lead to tough cookies.
Chill for Better Shape: For added control, chill the cookie dough for about 30 minutes before baking. This minimizes spreading and ensures thicker cookies.
Watch the Baking Time: Keep a close eye on the cookies as they bake; they should be lightly golden around the edges but soft in the center for the perfect texture.
Storage Tips: Store your Peanut Butter M&Ms Cookies in an airtight container at room temperature for up to a week, or freeze for longer freshness.
Make Ahead Options
These Peanut Butter M&Ms Cookies are perfect for busy home cooks who love to meal prep! You can prepare the cookie dough up to 24 hours in advance by mixing all the ingredients and storing it in an airtight container in the refrigerator. This not only keeps the dough fresh but also allows the flavors to meld beautifully. When you're ready to bake, simply scoop out the chilled dough, slightly flatten the balls, and press extra M&Ms on top before baking. To maintain their soft and chewy texture, avoid overbaking—keep an eye on them while they bake to ensure they stay delightfully tender. This way, you can enjoy freshly baked cookies with minimal effort throughout the week!
Peanut Butter M&Ms Cookies Recipe FAQs
How do I choose the best peanut butter for these cookies?
Absolutely! For the best flavor and texture, I recommend using creamy peanut butter for a well-blended consistency. If you prefer a bit of crunch, go with crunchy peanut butter; either way, make sure it's unsweetened for optimal sweetness balance.
What’s the best way to store these cookies to keep them fresh?
Fantastic question! Store your Peanut Butter M&Ms Cookies in an airtight container at room temperature for up to 5 days. If you want to keep them longer, refrigeration is an option; they will last up to a week chilled. Just let them sit at room temperature for a few minutes before enjoying!
Can I freeze Peanut Butter M&Ms Cookies?
Yes, definitely! To freeze, first place your cookies in a single layer on a baking sheet and freeze for about 1 hour. Once firm, transfer them to a freezer-safe bag or container, where they will stay fresh for up to 3 months. Whenever you crave a sweet treat, just thaw them at room temperature or microwave for a few seconds for that fresh-baked warmth.
What should I do if my cookies spread too much during baking?
Very important to note! If your cookies spread too much, there could be a couple of reasons: the butter was too warm or you overmixed the dough. Next time, try chilling the dough for about 30 minutes before baking, and ensure your butter is softened but not melted. This helps in maintaining their shape and texture!
Are there dietary considerations I should be aware of for these cookies?
Great point! These cookies contain peanut butter and eggs, so they are not suitable for those with peanut allergies or egg allergies. You can make substitutions, such as using sunflower seed butter for a nut-free option, and replace the egg with a flax egg (1 tablespoon ground flaxseed mixed with 3 tablespoons water, let sit for 5 minutes) for a vegan alternative. Always double-check labels if you're sharing with friends or family who have dietary restrictions!
