  • Granulated Sugar: 3/4 cup
  • Butter, Softened: 1/4 cup
  • Water: 1 tablespoon
  • Semi-Sweet Chocolate Chips: 1 cup (divided into 3/4 cup and 1/4 cup)
  • Large Egg: 1
  • Vanilla Extract: 1/2 teaspoon
  • All-Purpose Flour: 1 cup
  • Baking Soda: 1/4 teaspoon
  • Milk Chocolate Chips: 3/4 cup
  • Creamy Peanut Butter: 3/4 cup


  1. Preheat the Oven: Begin by preheating your oven to 350 degrees Fahrenheit. This ensures your oven is at the right temperature for baking.
  2. Combine Sugar, Butter, and Water: In a medium-sized, microwave-safe bowl, mix together the granulated sugar, softened butter, and water. Microwave this mixture on high for about 45 seconds or until the butter is completely melted.
  3. Melt Chocolate Chips: Add 3/4 cup of the semi-sweet chocolate chips to the melted butter mixture. Stir until the chocolate chips are fully melted and the mixture is smooth.
  4. Add Egg and Vanilla: Stir in the egg and vanilla extract into the chocolate mixture, ensuring it’s well mixed.
  5. Incorporate Dry Ingredients: Gently fold in the all-purpose flour and baking soda into the mixture. Stir until everything is just combined, making sure not to overmix.
  6. Cool the Batter: Allow the batter to cool down to room temperature. This step is crucial for the texture of the brownies.
  7. Add More Chocolate Chips: Once cooled, stir in the remaining 1/4 cup of semi-sweet chocolate chips and the 3/4 cup of milk chocolate chips into the batter.
  8. Prepare Muffin Cups: Spoon the batter evenly into Reynolds Staybrite muffin cups, filling each one.
  9. Bake the Brownies: Place the muffin cups in the preheated oven and bake for 13-15 minutes. The brownies are done when the top is set, and a toothpick inserted into the center comes out slightly wet.
  10. Create a Hole for Peanut Butter: After taking the brownies out of the oven, wait for the centers to fall upon cooling. If they don’t, gently tap the centers with the back of a teaspoon to create a small hole.
  11. Melt Peanut Butter: Place the creamy peanut butter in a small microwave-safe bowl. Microwave on high for 45 seconds, then stir until smooth.
  12. Add Peanut Butter to Brownies: While the brownies are still warm, spoon about a tablespoon of melted peanut butter into the center of each brownie.
  13. Top with Chocolate Chips: Sprinkle the remaining milk chocolate and semi-sweet chocolate chips over the peanut butter.
  14. Cool Completely: Allow the brownies to cool completely in the pan. This step is essential for them to set properly.
  15. Storage: Store the brownies at room temperature or in the refrigerator. For a warm treat, simply microwave a brownie for 10-15 seconds before serving.

Enjoy your homemade Peanut Butter Cup Brownies, a perfect treat for any chocolate and peanut butter lover!
