Ingredients

Scale

Wet Ingredients

  • 1/2 Cup Butter, softened
  • 3/4 Cup Peanut Butter
  • 3 Tablespoons Milk
  • 1 Tablespoon Vanilla Extract
  • 1 Large Egg

Dry Ingredients

  • 1 3/4 Cup All-Purpose Flour
  • 3/4 teaspoon Baking Soda

Add-ins

  • 1 1/4 Cup Brown Sugar
  • 1 Cup Chocolate Chips
  • 8 Reese’s Peanut Butter Cups, chopped
  • 1 1/2 Cup Mini Marshmallows

Instructions

  1. Preheat Oven: Preheat your oven to 375 degrees Fahrenheit. Line a baking sheet with parchment paper or a Silpat liner to prevent sticking.
  2. Cream Butter and Peanut Butter: In the bowl of a standing mixer, beat the softened butter and peanut butter together for about 1 minute until well combined and smooth.
  3. Add Sugar: Add the brown sugar to the butter mixture and continue beating for an additional 2 minutes until the mixture is fluffy and light.
  4. Mix Wet Ingredients: Incorporate the milk, vanilla extract, and egg into the butter and sugar mixture. Beat until the batter is smooth and homogenous.
  5. Combine Dry Ingredients: In a separate small bowl, whisk together the all-purpose flour and baking soda. Gradually add this dry mixture to your wet ingredients and mix until just combined and smooth.
  6. Add Mix-Ins: Fold in the chocolate chips, chopped Reese’s Peanut Butter Cups, and mini marshmallows evenly into the cookie dough.
  7. Scoop Dough: Using a cookie scoop or spoon, drop rounded tablespoons of dough onto the prepared baking sheet, spacing them evenly to allow for spreading.
  8. Bake: Bake the cookies in the preheated oven for 7 minutes or until the edges are golden and the centers are just set.
  9. Cool: Remove the baking sheet from the oven and allow the cookies to cool slightly before transferring them to a wire rack to cool completely.
  10. Store: Once cooled, store the cookies in an airtight container to maintain freshness and softness.

Notes

  • Store cookies in an airtight container to keep them fresh and chewy.
  • For even baking, use a cookie scoop to portion out dough evenly.
  • Do not overbake; cookies should still be slightly soft when removed from the oven for the best texture.
  • Mini marshmallows may melt slightly during baking, creating a gooey texture inside the cookies.
