Why You’ll Love This Recipe
This recipe is a delightful twist on a classic favorite, merging the creamy richness of peanut butter with the colorful crunch of M&Ms. It’s incredibly easy to make, requiring just a few pantry staples, and the dough comes together in no time. These cookies are perfect for last-minute guests, bake sales, or a special treat for yourself. With their vibrant colors and delicious flavor, they’ll be a hit with everyone.
Ingredients Notes
Ensure you’re using creamy peanut butter for a smoother texture, but if you prefer some extra crunch, crunchy peanut butter can be a delightful substitute. Use regular-sized M&Ms, but if you’re feeling creative, try using holiday-themed colors for festive occasions. Make sure all your ingredients are at room temperature for even blending.
Recipe Steps
Step 1
Preheat your oven to 350°F (175°C) and line your baking sheets with parchment paper. This ensures easy cleanup and prevents sticking.
Step 2
In a large bowl, mix the peanut butter, sugar, and an egg until well combined. The mixture should be smooth and creamy.
Step 3
Gently fold in the M&Ms, being careful not to crush them, as this will maintain their color and texture.

Step 4
Using a tablespoon, scoop the dough and place it onto the prepared baking sheets, spacing them about 2 inches apart to allow for spreading.
Step 5
Bake for 10-12 minutes or until the edges are lightly golden. Allow cookies to cool on the baking sheet for a few minutes before transferring to a wire rack.
Storage Options
Store your peanut butter M&M cookies in an airtight container at room temperature for up to a week. For longer storage, freeze the cookies in a single layer on a baking sheet before transferring to a freezer-safe bag. When ready to enjoy, thaw at room temperature or reheat gently in the oven for that fresh-baked taste.
Variations & Substitutions
If you’re catering to a dietary need, consider using a sugar substitute or a gluten-free flour blend to make these cookies suitable for more friends and family. For a flavor twist, add a pinch of cinnamon or a handful of chopped nuts into the dough.
Serving Suggestions
These cookies make a wonderful after-school snack or a vibrant addition to any picnic. Pair them with a glass of cold milk or a scoop of vanilla ice cream for an extra indulgent treat. They’re also great for gifting, especially around the holidays.
Frequently Asked Questions
Can I make these cookies ahead of time? Absolutely! The dough can be prepared and refrigerated for up to 48 hours before baking. This also enhances the flavors as they meld together, resulting in an even tastier cookie.
What’s the best way to ensure soft cookies? Ensure not to overbake the cookies; they should be set on the edges but still appear slightly underdone in the center. This will result in the perfect chewy texture once cooled.
Are there any allergy-friendly alternatives? For nut-free versions, substitute the peanut butter with a seed butter such as sunflower seed butter. Always double-check candy coatings for any allergens as well.
