Combine flour, baking soda, and salt in a bowl and set aside.

In the bowl of your mixer cream butter, peanut butter, sugar, and brown sugar until creamy.

Add vanilla and eggs one at a time, then incorporate the dry ingredients. Slowly add oats and peanut butter chips.

Place the dough in the refrigerator to chill for about 15 minutes. I just put in the whole mixer bowl.

Preheat oven to 350 F

Using a large cookie scoop (3 Tablespoons) drop dough onto a plate of mini Reese’s Pieces and form into a thick cookie disc by smashing down the dough ball a bit. I fit 6 cookies to a baking sheet.

Bake for 10 minutes.
