Tips for Making Heart-Shaped Brownies with Raspberry Mousse

  • When you are ready to bloom your gelatin, make sure the water is cold. Using cold water helps ensure a smooth texture and prevent lumps from forming
  • Don’t dump the gelatin in one spot in your bowl. Spread it out over the water’s surface to ensure even hydration.
  • For an added decorative touch, you can top your Heart-Shaped Brownies with fresh raspberries, a chocolate drizzle, and/or mint leaves.

Instructions
Prepare the Brownie Layer
  1. Take the Chocolate Crème Cake Roll out of the packaging and let sit on the counter to thaw for 30 minutes.
  2. Gently, unroll the cake roll and scrape off the crème filling. Put the filling in a bowl and set it aside.
  3. Use a heart-shaped cookie cutter to cut out brownie hearts from the cake roll. Set them aside.
Make the Raspberry Mousse
  1. In a small bowl, combine the gelatin with cold water. Let it bloom for 5-10 minutes.
  2. Add frozen raspberries and granulated sugar to a saucepan. Cook over medium-low heat, stirring occasionally, until the raspberries are completely broken down and soft.
  3. Turn off the heat and stir in the bloomed gelatin until it is fully dissolved.
  4. Strain the raspberry mixture through a fine sieve to remove seeds. Use a spatula to press out as much juice as possible. Set the raspberry juice/sauce aside to cool to room temperature.
  5. In a mixing bowl, add heavy whipping cream, powdered sugar, and vanilla extract. Whip until stiff peaks form.
  6. Gradually, fold the cooled raspberry sauce into the whipped cream. Fold in 1/4 c. at a time until you’ve added 1 c. total.
Assemble the Heart-Shaped Brownies
  1. Pour the raspberry mousse evenly into the heart-shaped molds, leaving room at the top for the brownie hearts.
  2. Place a brownie heart on top of the mousse in each mold, pressing gently to ensure the mousse and brownie are even.
  3. Place the silicone molds on a cookie sheet and freeze for at least 4 hours or overnight.
  4. Once the mousse has frozen, carefully remove the hearts from the silicone molds.
  5. Let the hearts sit at room temperature for 15-20 minutes before serving.
