Ingredients

Instructions

  1. Step 1: Preheat oven to 425°F (220°C). Grease four 6-ounce ramekins with vegetable oil and dust lightly with cocoa powder, tapping out excess.
  2. Step 2: In a microwave-safe bowl, melt 6 oz chopped bittersweet chocolate and 1/2 cup unsalted butter together in 30-second intervals, stirring well between each until smooth.
  3. Step 3: Whisk 3/4 cup powdered sugar into the chocolate mixture until fully combined.
  4. Step 4: Add 2 whole large eggs and 2 egg yolks to the mixture, whisking vigorously until smooth and glossy.
  5. Step 5: Gently fold in 1/4 cup all-purpose flour until just incorporated, being careful not to overmix.
  6. Step 6: Spoon a tablespoon of batter into each ramekin to cover the bottom.
  7. Step 7: Add about 2 tbsp creamy peanut butter into the center of each ramekin, then cover with the remaining batter, dividing it evenly.
  8. Step 8: Place ramekins on a baking sheet and bake for 12-14 minutes until the edges are set but the center still jiggles slightly.
  9. Step 9: Allow cakes to cool for 2 minutes, then run a knife around the edges and invert each ramekin onto a dessert plate.
  10. Step 10: Serve immediately to enjoy the molten peanut butter center.
