  • Baking sheets
  • Parchment paper
  • Mixing bowls
  • Whisk
  • Spatula
  • Metal Spatula
  • Piping bag
  • Electric Mixer or Hand Mixer

Ingredients
  

For the Fudgy Brownie Shells

  • 1 cup granulated sugar adds sweetness and creates a shiny, crackly top
  • 1/2 cup unsalted butter melted and slightly cooled
  • 2 large eggs room temperature
  • 1 tsp vanilla extract enhances chocolate flavor
  • 1/2 cup all-purpose flour provides structure without cakey texture
  • 1/2 cup unsweetened cocoa powder sifted to prevent lumps
  • 1/4 tsp salt balances sweetness and enhances chocolate
  • 1/4 tsp baking powder adds slight lift for tender but sturdy shells

For the Peanut Butter Mousse Filling

  • 1 cup creamy peanut butter classic creamy style recommended
  • 4 oz cream cheese softened
  • 1 cup powdered sugar sweetens and smooths filling
  • 1 tsp vanilla extract enhances filling flavor
  • 1 cup heavy whipping cream cold, whipped to stiff peaks

Toppings

  • crushed chocolate sandwich cookies or peanut butter cookies for a crunchy contrast
  • chocolate syrup or warmed hot fudge sauce for an extra decadent drizzle

Instructions
 

  • Step 1: Preheat oven to 350°F (175°C) and line two large baking sheets with parchment paper.
  • Step 2: In a medium bowl, whisk melted butter and granulated sugar until combined. Add eggs and vanilla extract; whisk until smooth and glossy.
  • Step 3: Sift together flour, cocoa powder, salt, and baking powder. Gently fold into wet ingredients with a spatula, careful not to overmix.
  • Step 4: Drop heaping tablespoons of batter onto prepared sheets about 4 inches apart. Spread into thin 5-6 inch circles.
  • Step 5: Bake one sheet at a time for 6-8 minutes until edges are set but centers slightly underdone for pliability.
  • Step 6: Remove rounds and cool 30 seconds. While warm, lift with a thin metal spatula and drape over a spoon handle or rolling pin to shape into tacos. Press lightly and let cool completely.
  • Step 7: In a large bowl, beat cream cheese and peanut butter until smooth. Add powdered sugar and vanilla, mixing until fully incorporated.
  • Step 8: In a separate bowl, whip cold heavy cream to stiff peaks. Fold whipped cream gently into peanut butter mixture in two additions until light and fluffy.
  • Step 9: Refrigerate mousse at least 30 minutes to firm slightly for easier piping.
  • Step 10: Transfer mousse to a piping bag fitted with a star tip. Pipe generous amounts into each cooled brownie shell.
  • Step 11: Sprinkle crushed cookies over exposed filling and drizzle with chocolate syrup or warm fudge sauce.
  • Step 12: Chill assembled tacos in refrigerator for 15-20 minutes before serving to allow mousse to set while keeping shells tender.

Notes

Swap peanut butter with almond or cashew butter for a nutty twist. Add fresh raspberries or sliced bananas on top for a fruity surprise. Store assembled tacos in an airtight container in the fridge up to 3 days. Brownie shells can be prepped a day ahead and stored at room temperature. Avoid freezing assembled tacos to maintain mousse texture.
