These Peanut Butter M&M Cookies are the perfect combination of chewy peanut butter goodness and crunchy chocolate candy! Full of nutty buttery flavor and nostalgic M&M's!
Cream together the butter, peanut butter, and sugars until light and fluffy.
Beat in the eggs one at a time, then add the vanilla extract.
Slowly mix in the baking soda and flour until just combined, being careful not to overmix.
Chill the dough for at least 1 hour to prevent the cookies from spreading too much.
Preheat the oven to 350°F. Scoop the dough and shape into 2 inch balls
Place the dough balls on a parchment-lined baking sheet, ensuring they are spaced out to allow for spreading.
Bake for 18-20 minutes,or until there are slight cracks on top and lightly browned edges.
Let the cookies rest on the baking sheet for 5-10 minutes before transferring them to a cooling rack.
Notes
Chill the Dough: it's critical to chill the dough to prevent the cookies from spreading too much.
Don't Overbake: The cookies will appear slightly underdone in the center at the end of the cooking time, but they will firm up as they cool.
Space Them Out: leave ample space between each dough ball on the baking sheet.
Make Them Bigger or Smaller: Adjust the baking time if you make smaller or larger cookies. Just keep an eye on the edges for slight browning. We like them big and 1 cookie is very satisfying!
