Method
 

  1. Step 1: Preheat oven to 350°F (175°C). Line two large baking sheets with parchment paper.
  2. Step 2: In a medium bowl, whisk melted butter and granulated sugar until combined. Add eggs and vanilla extract; whisk until shiny and well blended.
  3. Step 3: Sift flour, cocoa powder, salt, and baking powder over wet ingredients. Fold gently with a spatula until thick and smooth; do not overmix.
  4. Step 4: Drop heaping tablespoons of batter onto prepared sheets spaced 4 inches apart. Spread into thin circles about 5–6 inches in diameter.
  5. Step 5: Bake one sheet at a time for 6–8 minutes until edges are set but centers remain soft.
  6. Step 6: Remove from oven and cool for 30 seconds. While warm, lift each round with a thin metal spatula and drape over a wooden spoon handle or rolling pin to form taco shape. Let cool completely.
  7. Step 7: In a large bowl, beat softened cream cheese and creamy peanut butter until smooth. Add powdered sugar and vanilla extract; mix well. Whip cold heavy cream to stiff peaks and fold gently into peanut butter mixture in two additions.
  8. Step 8: Transfer mousse to a piping bag or zip-top bag with a corner cut. Pipe mousse generously into each brownie shell.
  9. Step 9: Sprinkle crushed cookies on top and drizzle with chocolate syrup or warm hot fudge sauce.
  10. Step 10: Refrigerate assembled tacos for 15–20 minutes before serving to let mousse set. Serve chilled.

Notes

Store brownie shells in an airtight container at room temperature for up to 1 day. Mousse can be made hours ahead and refrigerated. Assemble tacos just before serving for best texture. Freeze shells up to 2 months before filling if desired. Variations include using almond or cashew butter in mousse, adding espresso powder, or topping with chopped peanuts and sprinkles.
