Equipment

  • 1 Mixing bowl (for brownie dough)
  • 1 Mixing bowl (for peanut butter filling)
  • (1) Baking sheet
  • Parchment paper or Nonstick baking spray
  • 1 Spoon or cookie scoop
  • 1 Spoon (for melting chocolate)
  • 1 Microwave-safe bowl (for melting chocolate)
  • 1 Refrigerator (for chilling peanut butter filling)

Ingredients
  

For the Cookie Dough:

  • 1 box Brownie mix 18 oz
  • 2 Eggs
  • ½ cup Unsalted butter melted
  • 1 tsp Vanilla extract
  • 1 tbsp All-purpose flour optional, for texture

For the Peanut Butter Filling:

  • ¾ cup Creamy peanut butter
  • 1 cup Powdered sugar

For the Chocolate Topping:

  • 1 cup Chocolate chips milk or dark, your choice

Instructions
 

Prepare the Brownie Dough:

  • Preheat your oven to 350°F (175°C). Line a baking sheet with parchment paper. In a large mixing bowl, combine the brownie mix, eggs, melted butter, and vanilla extract. Stir until smooth. Optionally, add 1 tablespoon of flour for a slightly firmer dough. Set aside.

Make the Peanut Butter Filling:

  • In a separate bowl, mix the peanut butter and powdered sugar until smooth. Roll into small balls (about 1 tablespoon each), then refrigerate for 15-20 minutes to firm up.

Shape the Cookies:

  • Scoop about 2 tablespoons of brownie dough and roll it into a ball. Place the dough on the prepared baking sheet, leaving some space between each cookie. Press a thumb into the center of each ball to make a small indent. Place the chilled peanut butter filling ball into the indent, and enclose the filling by pinching the dough around it.

Bake the Cookies:

  • Bake the cookies in the preheated oven for 10-12 minutes or until the edges are set and the centers are still soft. Don’t overbake – the center will continue to set as they cool.

Add the Chocolate Topping:

  • While the cookies cool, melt the chocolate chips in a microwave-safe bowl, stirring every 20-30 seconds until smooth. Spoon a generous amount of melted chocolate over the top of each cookie, covering the peanut butter filling.

Cool and Serve:

  • Allow the cookies to cool completely before serving. The chocolate will harden as it cools, giving you a glossy finish.

Notes

  • Peanut Butter Options: For best results, use smooth, creamy peanut butter that does not separate. Crunchy peanut butter can be used, but it will change the texture of the filling.
  • Chocolate Topping: You can use milk chocolate or dark chocolate chips based on your preference for sweetness. For a smoother topping, consider using a chocolate bar instead of chips.
  • Storing Leftovers: Store leftover cookies in an airtight container at room temperature for 4-5 days. For longer storage, freeze the cookies for up to 3 months.
  • Gluten-Free Option: Use a gluten-free brownie mix and substitute the all-purpose flour with a gluten-free flour blend for a gluten-free version.
