Delicious Chocolate Peanut Butter Brownie Bites that combine rich chocolatey brownie with creamy peanut butter centers. These bite-sized treats are easy to make with a simple batter, baked to perfection, and filled with melted peanut butter for a gooey surprise.

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. Combine sugar, butter, and water: In a microwave-safe bowl, mix together the granulated sugar, softened butter, and water. Microwave in 45-second increments, stirring in between, until the butter is melted and the mixture is hot.
  2. Melt semi-sweet chocolate: Add the 1 cup of semi-sweet chocolate chips to the warm mixture and stir until completely melted and smooth. If needed, microwave for a few more seconds and stir again.
  3. Add egg and vanilla: Stir in the egg and vanilla extract until the mixture is well combined.
  4. Add dry ingredients: Mix in the all-purpose flour and baking soda just until the batter is combined and smooth, resulting in a thick and glossy batter.
  5. Cool batter slightly: Let the batter cool at room temperature for 5–10 minutes so it’s not too hot before adding milk chocolate chips.
  6. Fold in milk chocolate chips: Gently fold in 3/4 cup milk chocolate chips until evenly distributed in the batter.
  7. Prepare for baking: Preheat the oven to 350°F (175°C). Grease a muffin tray or line with paper liners. Spoon the batter into the muffin cups, filling each about 3/4 full.
  8. Bake brownie bites: Bake for 14–16 minutes or until the tops look set and a toothpick inserted near the edge comes out mostly clean with a few moist crumbs.
  9. Cool and create wells: Remove from the oven and let cool in the pan for 5 minutes. If centers don’t sink naturally, gently press the center of each brownie bite with the back of a spoon to make a small well.
  10. Melt peanut butter: Place the creamy peanut butter in a microwave-safe bowl and microwave in short bursts until melted and smooth.
  11. Fill brownie bites: Spoon about 1 tablespoon of melted peanut butter into the well of each brownie bite. Optionally, top with extra chocolate chips.
  12. Cool and serve: Allow the brownie bites to cool until the peanut butter thickens slightly. Serve warm or at room temperature for the best flavor and texture.

Notes

  • Make sure to cool the batter slightly before folding in the milk chocolate chips to prevent melting.
  • Use paper liners in the muffin tray for easier removal and less cleanup.
  • The peanut butter filling can be substituted with other nut butters for variety.
  • Store leftovers in an airtight container at room temperature for up to 3 days or refrigerated for up to a week.
  • For a gluten-free version, use a gluten-free all-purpose flour blend.
