My peanut butter M&M cookies have the perfect ratio of peanut butter to M&M's resulting in a soft, chewy, and sweet cookie. I use peanut butter M&Ms for the best flavor!
Preheat the oven to 350 degrees F, and then line a cookie sheet with parchment paper.
In a large mixing bowl, cream together the unsalted butter and light brown sugar using an electric mixer.
Next, add a room-temperature egg, peanut butter, and vanilla extract. Beat all the ingredients together until they are well combined.
In a small bowl, whisk together the flour, baking soda, and salt. Gradually add the dry ingredients to the wet ingredients. Mix them until they are just combined.
Fold in the peanut M&M's, making sure they are evenly distributed.
Cover the bowl with a lid or plastic wrap, and then chill the peanut butter cookie dough in the fridge for at least 30 minutes.
Using a large cookie scoop, scoop out the dough and place each dough ball on the prepared baking sheet. Be sure to place them about 2 inches apart.
Bake the cookies for 10 minutes or until they are golden brown around the edges. Let them cool on the baking sheet for a few minutes before transferring them to a wire rack to cool completely.
Notes
Always use butter and eggs at room temperature so the dough comes together evenly in the mixer and gives the cookies the best texture.
To keep the cookies from spreading too much, chill the cookie dough in the refrigerator for at least 30 minutes.
Place the cookie dough balls at least 2 inches apart on the lined baking sheet.
To avoid hot spots in the oven, rotate the cookie sheet halfway through baking so all my cookies bake evenly.
Let the cookies rest on the baking sheet on the counter for a few minutes to help them set and keep them soft.
Store leftovers in an airtight container on the counter for a few days or in the freezer up to 3 months.
