Peanut Butter M&M Cookies Recipe
Introduction
Peanut Butter M&M Cookies are a delightful twist on classic peanut butter cookies, packed with colorful mini M&Ms and melty chocolate chips. These treats combine rich peanut butter flavor with a satisfying crunch, making them perfect for any occasion.

Ingredients
- 1 cup salted butter (softened at room temperature)
- 1 cup creamy peanut butter (softened at room temperature)
- 2 1/2 teaspoons pure vanilla extract
- 1 1/2 cups brown sugar
- 1/2 cup granulated sugar
- 2 whole large eggs
- 1 egg yolk
- 2 1/4 cups all-purpose flour
- 1 teaspoon baking soda
- 1 teaspoon baking powder
- 1 1/2 cups peanut butter mini M&Ms (or regular M&Ms)
- 3/4 cups mini chocolate chips
Instructions
- Step 1: Preheat your oven to 350°F (175°C) and line baking sheets with parchment paper or silpat mats.
- Step 2: In a large mixing bowl, use an electric mixer or stand mixer with a paddle attachment to cream together the softened butter and both sugars until the mixture is light and creamy, about 2 to 4 minutes.
- Step 3: Add the peanut butter, vanilla extract, whole eggs, and egg yolk to the butter-sugar mixture. Mix until everything is combined, making sure to scrape down the sides of the bowl as needed.
- Step 4: In a separate medium bowl, whisk together the all-purpose flour, baking soda, and baking powder until well blended.
- Step 5: Gradually add the dry ingredients to the wet mixture and stir just until a dough forms. Fold in the peanut butter M&Ms and mini chocolate chips evenly.
- Step 6: Using a large cookie scoop (about 3 tablespoons), form dough balls and place them on the prepared baking sheets, spacing them about 2 inches apart.
- Step 7: Bake for 12 to 13 minutes, or until the edges turn a light golden brown. Optionally, sprinkle the tops with flaky sea salt once out of the oven.
- Step 8: Let cookies cool on the baking sheet for a few minutes before transferring them to a wire rack to cool completely. Enjoy!
Tips & Variations
- For extra flavor, toast the peanut butter M&Ms lightly before adding them to the dough.
- Substitute regular M&Ms if peanut butter mini M&Ms aren’t available.
- Adding a sprinkle of flaky sea salt on top heightens the sweet and salty contrast.
- Chill the cookie dough for 30 minutes before baking to reduce spreading and enhance texture.
Storage
Store the cooled cookies in an airtight container at room temperature for up to one week. For longer storage, freeze the cookies in a sealed container or freezer bag for up to three months. To reheat, warm in a low oven for a few minutes or microwave briefly to enjoy fresh-baked softness.

FAQs
Can I use natural peanut butter instead of creamy peanut butter?
Natural peanut butter can be used, but it may affect the texture slightly because it is less creamy and more oil-separated. Stir well before measuring and consider chilling the dough if it feels too soft.
How can I make these cookies gluten-free?
Replace the all-purpose flour with a gluten-free flour blend that includes xanthan gum, and be sure all other ingredients are certified gluten-free to avoid cross-contamination.

- 1 cup creamy peanut butter, softened at room temperature
- 2 1/2 teaspoons pure vanilla extract
- 2 whole large eggs
- 1 egg yolk
Dry Ingredients
- 1 1/2 cups brown sugar
- 1/2 cup granulated sugar
- 2 1/4 cups all-purpose flour
- 1 teaspoon baking soda
- 1 teaspoon baking powder
Add-ins
- 1 1/2 cups peanut butter mini M&Ms (or regular M&Ms)
- 3/4 cups mini chocolate chips
- Flaky sea salt (optional, for garnish)
Instructions
- Preheat Oven and Prepare Baking Sheets: Preheat your oven to 350°F (175°C) and line baking sheets with parchment paper or silicone baking mats to ensure cookies don’t stick and bake evenly.
- Cream Butter and Sugars: In a large mixing bowl, use an electric mixer or stand mixer fitted with the paddle attachment to cream together the softened butter and both sugars until the mixture is light and creamy, usually about 2-4 minutes.
- Add Wet Ingredients: Mix in the creamy peanut butter, pure vanilla extract, the two whole eggs, and one egg yolk. Scrape the sides of the bowl to ensure all ingredients are incorporated and mix again until fully combined.
- Combine Dry Ingredients: In a separate medium bowl, whisk together the all-purpose flour, baking soda, and baking powder until evenly combined.
- Form the Dough: Gradually add the dry ingredients into the wet ingredients and mix just until a cookie dough forms. Fold in the peanut butter mini M&Ms and mini chocolate chips until evenly distributed throughout the dough.
- Scoop and Bake: Using a large cookie scoop (about 3 tablespoons of dough), form dough balls and place them on the prepared baking sheets, leaving about 2 inches of space between each cookie. Bake in the preheated oven for 12-13 minutes or until the edges have turned a light golden brown.
- Cool and Serve: Optional: Sprinkle the tops of the warm cookies with flaky sea salt for added flavor. Let the cookies cool on the baking sheet for a few minutes before transferring them to a wire cooling rack. Enjoy!
Notes
- For best results, ensure butter and peanut butter are softened to room temperature before mixing.
- Do not overmix the flour into the wet ingredients to maintain a tender cookie texture.
- You can substitute regular M&Ms if peanut butter mini M&Ms are unavailable.
- Adding flaky sea salt on top before serving enhances the sweet and salty flavor profile.
- Store cookies in an airtight container at room temperature for up to 5 days.
- To keep cookies soft longer, add a slice of bread to the container to maintain moisture.
