Peanut butter lava fudge cupcakes are rich chocolate cupcakes with a gooey peanut butter center that melts into the cake as it bakes, creating an indulgent dessert experience.

Ingredients

  • 3/4 cup all-purpose flour
  • 1/3 cup unsweetened cocoa powder
  • 1 tsp baking powder
  • 1/4 tsp salt
  • 1/2 cup semi-sweet chocolate (melted)
  • 1/2 cup unsalted butter (melted)
  • 1/2 cup granulated sugar
  • 1/3 cup brown sugar
  • 2 large eggs
  • 1 tsp vanilla extract
  • 1/2 cup milk
  • Peanut Butter Lava Filling:
  • 1/2 cup creamy peanut butter
  • 1/4 cup powdered sugar
  • Pinch of salt (optional)
  • Optional toppings: Chocolate ganache, whipped cream, chopped peanuts, mini peanut butter cups

Instructions

  1. Preheat oven to 350°F (175°C) and line a muffin tin with cupcake liners.
  2. In a bowl, whisk together flour, cocoa powder, baking powder, and salt.
  3. In a separate large bowl, mix melted butter, melted chocolate, granulated sugar, and brown sugar until combined.
  4. Add eggs one at a time, mixing well, then stir in vanilla and milk.
  5. Gradually add dry ingredients to the wet mixture, stirring until just combined.
  6. In another bowl, mix peanut butter, powdered sugar, and salt until smooth. Roll into 12 small balls and freeze for 10–15 minutes.
  7. Fill each cupcake liner halfway with chocolate batter, place one peanut butter ball in the center, then cover with more batter until 3/4 full.
  8. Bake for 18–22 minutes, until edges are set and centers look slightly soft.
  9. Cool in pan for 5 minutes, then transfer to wire rack. Serve warm for lava effect or let cool for a fudgy center.

Notes

  • Freeze the peanut butter balls to help keep the center gooey after baking.
  • Serve cupcakes slightly warm to enjoy the molten center.
  • Top with chocolate ganache or whipped cream for added indulgence.
  • Store leftovers in the fridge and reheat briefly before serving.
