Ingredients

Brownie Batter

  • 3/4 cup granulated sugar
  • 1/4 cup butter, softened
  • 1 tablespoon water
  • 1 cup semi-sweet chocolate chips or chocolate bar
  • 1 large egg
  • 1/2 teaspoon vanilla extract
  • 1 cup all-purpose flour
  • 1/4 teaspoon baking soda
  • 3/4 cup milk chocolate chips

Peanut Butter Filling

  • 1/2 cup creamy peanut butter

Instructions

  1. Prepare Sugar and Butter Mixture: In a microwave-safe bowl, combine the granulated sugar, softened butter, and water. Microwave in 45-second increments, stirring between each, until the butter is completely melted and the mixture is hot but not boiling.
  2. Melt Semi-Sweet Chocolate: Add the 1 cup semi-sweet chocolate chips to the warm butter mixture and stir until the chocolate is fully melted and smooth. If needed, microwave for a few additional seconds and stir again to ensure a glossy, even blend.
  3. Add Egg and Vanilla: Stir in the egg and vanilla extract thoroughly until the mixture is well combined and smooth.
  4. Incorporate Dry Ingredients: Add the all-purpose flour and baking soda to the wet mixture. Gently fold in just until the batter is thick, glossy, and combined without overmixing.
  5. Cool Batter Slightly and Add Chips: Let the batter cool at room temperature for 5 to 10 minutes, which prevents the milk chocolate chips from melting immediately. Then fold in the 3/4 cup milk chocolate chips evenly throughout the batter.
  6. Preheat Oven and Prepare Muffin Tray: Preheat the oven to 350°F (175°C). Grease or line a muffin tray with paper liners to prevent sticking.
  7. Fill Muffin Cups: Spoon the brownie batter into each muffin cup, filling about three-quarters full to allow room for rising but keeping them bite-sized.
  8. Bake Brownie Bites: Bake in the preheated oven for 14 to 16 minutes or until the tops are set and a toothpick inserted near the edge comes out mostly clean with a few moist crumbs. Avoid overbaking to maintain fudginess.
  9. Cool and Create Peanut Butter Wells: Remove the tray from the oven and let the bites cool in the pan for about 5 minutes. If the centers have not sunk naturally, gently press each center with the back of a tablespoon to create a well for the peanut butter filling.
  10. Melt Peanut Butter: Place the creamy peanut butter in a microwave-safe bowl and heat in short bursts until smooth and melted, making it easy to spoon.
  11. Fill Centers and Add Toppings: Spoon approximately 1 tablespoon of the melted peanut butter into the center well of each brownie bite. Optionally, top with extra chocolate chips for added texture and chocolate flavor.
  12. Cool and Serve: Allow the peanut butter-filled brownie bites to cool until the peanut butter thickens slightly. Serve warm or at room temperature for the best flavor and texture.

Notes

  • To ensure fudgy brownies, avoid overbaking; check early to catch the moist crumb texture.
  • Cooling the batter before adding milk chocolate chips prevents them from melting prematurely.
  • You can substitute peanut butter with almond or cashew butter for a different nutty flavor.
  • Store leftover brownie bites in an airtight container at room temperature for up to 3 days or refrigerate for up to one week.
  • For a more intense chocolate flavor, use a higher percentage cocoa chocolate bar for melting.
