1cupcreamy peanut butter
1/2cupgranulated sugar
1/2cupbrown sugar
2largeeggs, room temperature
2teaspoonsvanilla extract
1cupall-purpose flour
1teaspoonbaking soda
1/4teaspoonsalt
1/8teaspoonground cinnamon
2cupsold fashioned oats
3/4cupsemi-sweet chocolate chips, (divided)
1cupm&m's, (divided)
Instructions
Preheat oven to 350 degrees F.
In the bowl of an electric stand mixer (or an electric hand mixer), cream butter, peanut butter, and sugars together until light and creamy (2 minutes).
Mix in the eggs and vanilla until combined. Scrape down sides of bowl as needed.
Whisk the flour, soda, salt, and cinnamon together in a small mixing bowl. Add it to the butter mixture along with the oats. Mix until combined.
Stir in 1/2 cup chocolate chips and 1/2 cup m&m’s by hand with a wooden spoon.
Use a 1/4 cup trigger scoop to portion dough onto a baking sheet leaving 3 inches between each. (I fit 8 onto a half-sheet pan.) Press remaining m&m’s into the top of each mound of dough.
Bake for 10 minutes. (They won’t look done but trust me, do NOT cook them any longer!)
Press remaining chocolate chips into the top of the cookies as soon as they come out. Let cookies cool 5 minutes on the pan and then move them to a cooling rack.
