Ingredients

Scale
  • 2 large eggs
  • 120 grams (4.2 oz) granulated sugar
  • 100 grams (3.5 oz) dark chocolate
  • 100 grams (3.5 oz) creamy peanut butter
  • 50 grams (1.8 oz) all-purpose flour
  • 50 grams (1.8 oz) additional chopped dark chocolate for drizzling
  • 30 grams (1 oz) powdered sugar
  • 18 milliliters (0.6 fl oz) neutral oil
  • 1 teaspoon vanilla extract

Instructions

  1. Oven Preparation: Preheat oven to 350°F (180°C). Grease a 9×5-inch loaf pan and line with parchment paper, allowing overhang for easy removal.
  2. Chocolate Base Creation: Melt dark chocolate and butter using double boiler or microwave until smooth. Integrate unsweetened cocoa powder, stirring until uniform.
  3. Wet Ingredient Fusion: Whisk eggs, sugar, vegetable oil, and vanilla extract until creamy. Gradually blend in cooled chocolate mixture, ensuring complete incorporation.
  4. Batter Assembly: Fold flour and sea salt into chocolate mixture, maintaining a smooth consistency. Transfer batter to prepared pan, leveling surface with a spatula.
  5. Brownie Baking: Bake for 20-22 minutes, preserving a fudgy center. Cool completely at room temperature for approximately one hour.
  6. Peanut Butter Filling: Whip butter, peanut butter, powdered sugar, vanilla extract, and salt until light and fluffy. Create a smooth, spreadable consistency.
  7. Filling Application: Spread peanut butter mixture evenly across cooled brownie base. Refrigerate 20-30 minutes to set filling.
  8. Chocolate Glaze Topping: Melt additional dark chocolate with neutral cooking oil until glossy. Pour over chilled peanut butter layer, ensuring complete coverage.
  9. Final Chilling: Refrigerate to set chocolate topping completely, approximately 30-45 minutes. Remove from pan using parchment paper edges.
  10. Serving Preparation: Slice into precise rectangular bars. Store in airtight container in refrigerator to maintain optimal texture and freshness.

Notes

  • Chocolate Quality Matters: Select premium dark chocolate with 60-70% cocoa content for richer, more complex flavor profile.
  • Prevent Dry Brownies: Do not overbake; remove from oven when center still appears slightly underdone to maintain ultimate fudgy texture.
  • Smooth Peanut Butter Tip: Use room temperature ingredients for seamless mixing and lighter filling consistency.
  • Glaze Perfection: Add neutral oil when melting chocolate to achieve glossy, crack-free chocolate topping that sets beautifully.
