Step-by-Step Instructions

Let’s make this spooky brain step-by-step. It’s easy and so much fun!

Step 1: Make the Chocolate Mousse

In a cold metal or glass bowl, whip 1 cup heavy cream to soft peaks. Set aside.
Fill a saucepan one-third with water and bring to a simmer.
In a medium heatproof bowl, melt 6 ounces chopped semisweet chocolate and 3 tablespoons unsalted butter over the simmering water, stirring until smooth. Set aside.
In another heatproof bowl, beat 1 large egg, 2 yolks, and a pinch of kosher salt with an electric mixer until light, about 1 minute.
Slowly add 1/3 cup granulated sugar while beating.
Place the egg mixture over the simmering water (now at a rapid simmer) and whisk constantly until pale, fluffy, and hot, 3-5 minutes.
Remove from heat and whip until cool, thick, and holds a ribbon, about 3 minutes.
Whisk a quarter of the egg foam into the chocolate to lighten, then briskly fold in the rest.
Fold in the whipped cream gently to keep the mixture light. Refrigerate.

Tip: Keep the water simmering, not boiling, to avoid overcooking the eggs.

Step 2: Make the Frosting

In a stand mixer with a paddle attachment (or large bowl with a handheld mixer), combine 1 1/2 pounds confectioners’ sugar, 1 1/2 cups unsalted butter, and a pinch of kosher salt.
Mix on low until mostly incorporated, then add 1 tablespoon vanilla extract.
Increase to medium-high and mix until smooth, adding 2-4 tablespoons milk to adjust consistency.
Mix in bright red gel food coloring until the frosting is cotton-candy pink.
Transfer to a piping bag with a medium plain tip.

Tip: Add food coloring gradually to get the perfect pink shade.

Step 3: Make the Rice Cereal Shell

In a large pot over medium-low heat, melt one 10-ounce bag of mini marshmallows and 3 tablespoons unsalted butter, stirring until smooth.
Add one 12-ounce box of crisp rice cereal and mix to combine.
Spray the inside of a medium bowl and your hands with nonstick cooking 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 and even out the cereal layer.

Tip: Work quickly while the mixture is warm and pliable.

Step 4: Fill and Seal the Brain

Once the cereal shell has set (about 5 minutes), remove the inner bowl.
Spoon the chilled chocolate mousse into the center of the shell.
Flatten the remaining cereal mixture and lay it over the mousse, pressing the sides to seal.
Refrigerate until chilled, about 15 minutes.

Tip: Press gently to avoid squeezing out the mousse.

Step 5: Shape and Decorate

Invert the cereal brain onto a platter or baking sheet.
Gently shape to resemble a brain with soft curves.
Pipe the pink frosting in a brain-like pattern (wiggly lines and folds).
Use a butter knife or offset spatula to make a 1-inch line down the center.
Sprinkle red sprinkles over the center line for a spooky effect.

Tip: Practice piping on parchment first for a neat brain pattern.
