Crispy Rice Cereal Brain (The Ultimate Halloween Dessert!)

The finished, spooky, and impressive Stuffed Crispy Rice Cereal Brain being sliced for the first time at a fun and sophisticated Halloween party.

An elaborate and spooky no-bake dessert, this ‘Stuffed Crispy Rice Cereal Brain’ is a perfect centerpiece for a Halloween party. The recipe features a shell molded from a classic crispy rice cereal and marshmallow mixture. This ‘brain’ shell is then filled with a rich, from-scratch chocolate mousse made with whipped cream and a whipped egg foam. The entire dessert is sealed, unmolded, and then meticulously decorated with a pink-tinted buttercream frosting, piped on in a brain-like pattern and finished with red sprinkles for a gory effect.

Ingredients

  • For the Chocolate Mousse:
  • 1 cup heavy cream
  • 6 ounces semisweet chocolate, chopped
  • 3 tablespoons unsalted butter
  • 1 large egg plus 2 yolks
  • Pinch of kosher salt
  • 1/3 cup granulated sugar
  • For the Frosting:
  • 1 1/2 pounds (6 cups) confectioners’ sugar
  • 3 sticks (1 1/2 cups) unsalted butter, at room temperature
  • Pinch of kosher salt
  • 1 tablespoon pure vanilla extract
  • 2 to 4 tablespoons milk
  • Bright red gel food coloring
  • Red sprinkles, for topping
  • For the Rice Cereal Treat Shell:
  • One 10-ounce bag mini marshmallows
  • 3 tablespoons unsalted butter
  • One 12-ounce box crisp rice cereal
  • Nonstick cooking spray

Instructions

  1. Make the Chocolate Mousse: Whip the heavy cream to soft peaks and set aside. Melt the chocolate and butter together in a double boiler. In a separate heatproof bowl, beat the egg, yolks, and salt, then gradually beat in the sugar. Place this bowl over the simmering water and whisk constantly for 3-5 minutes, until pale and fluffy. Remove from heat and whip until cool and thick. Fold the egg foam into the chocolate, then fold in the whipped cream. Refrigerate.
  2. Make the Frosting: In a stand mixer, beat the confectioners’ sugar, butter, and salt on low speed until incorporated. Add the vanilla and milk, then increase speed to medium-high and beat until smooth. Mix in enough red food coloring to make the frosting pink. Transfer to a piping bag.
  3. Make the Rice Cereal Shell: Melt the marshmallows and butter in a large pot over medium-low heat. Stir in the rice cereal until combined.
  4. Assemble the Brain: Spray the inside of a medium bowl and your hands with nonstick spray. Line the bowl with a 2-inch-thick layer of the warm cereal mixture. Spray the outside of a smaller bowl and press it into the center to compress the cereal layer.
  5. Once the cereal shell has set, spoon the prepared chocolate mousse into the center. Flatten the remaining cereal mixture and use it to cover the mousse, pressing the sides to seal. Refrigerate for about 15 minutes to chill.
  6. Invert the stuffed shell onto a platter and gently shape it to look more like a brain.
  7. Pipe the pink frosting on top of the cereal shell in a brain-like squiggly pattern. Use a butter knife to make a line down the center. Top the center line with red sprinkles.

Notes

  • Special Equipment: The recipe recommends a piping bag fitted with a medium plain tip.
  • This is a multi-component, showstopper dessert that requires several steps, but does not require any baking.
  • Oiling your hands and the bowls with nonstick spray is a crucial step to prevent the sticky marshmallow mixture from adhering to everything.
  • The chocolate mousse is a classic, from-scratch version that requires careful attention to temperature and technique.
