Base Ingredients
  • 2 cups all-purpose flour
  • 1/2 teaspoon baking powder
  • 1 teaspoon baking soda
  • pinch salt
  • 2 sticks unsalted butter, softened
  • 1 cup granulated sugar
  • 1 cup packed light brown sugar
  • 2 large eggs, at room temperature
  • 1 tablespoon vanilla extract
  • 1/4 cup peanut butter
  • 2 cups quick-cooking oats
Mix-ins
  • 1 cup milk chocolate chips
  • 1 cup white chocolate chips
  • 1 cup peanut butter chips
  • 1 cup miniature marshmallows (or large cut into fourths)

Method
 

Preparation
  1. Preheat the oven to 350 degrees F.
  2. Line a baking sheet with parchment paper.
  3. In a large bowl, combine the flour, baking powder, and baking soda.
Mixing
  1. In a separate bowl, beat the softened butter, granulated sugar, and light brown sugar with a mixer on medium-high speed until fluffy.
  2. Add the eggs one at a time while mixing on medium speed, then mix in the vanilla extract.
  3. Add the peanut butter and mix until smooth.
  4. Gradually add the flour mixture and mix on low speed until just combined.
  5. Stir in the oats, chocolate chips, white chocolate chips, peanut butter chips, and marshmallows using a wooden spoon.
Baking
  1. Drop heaping tablespoonfuls of dough onto the prepared baking sheets, spacing them about 3 inches apart.
  2. Bake in batches for 8-10 minutes, until golden.
  3. For added effect, place marshmallows on top of the dough before baking, and consider topping with melted chocolate almond bark.

Notes

Store leftovers in sealed containers promptly. Let cookies cool completely before storing. For longer storage, freeze baked cookies in a sealed freezer bag for up to 2 months.
