Ingredients

• 2 cups Heavy whipping cream
• 0.25 cup Powdered sugar
• 1 tablespoon Gelatin powder (unflavored)
• 2 tablespoons Cold water
• 0.5 cup Flavor base (e.g., melted chocolate, fruit puree, or extract)
• 1 teaspoon Vanilla extract (optional)

Directions

Step 1

In a small bowl, combine the gelatin powder and cold water. Let it bloom for 5 minutes, then gently heat in the microwave for 10-15 seconds or until fully dissolved. Let it cool slightly.

Step 2

In a large mixing bowl, whip the heavy whipping cream and powdered sugar together using a hand or stand mixer on medium-high speed until soft peaks form.

Step 3

Choose your flavor base. If using melted chocolate, ensure it is cooled to room temperature before adding. If using fruit puree, ensure it is smooth and strained (if necessary). If using an extract, measure it precisely to taste.

Step 4

Add the prepared gelatin to your chosen flavor base and mix to combine. The gelatin ensures the mousse holds its shape when used as a cake filling.

Step 5

Gradually fold the flavor base mixture into the whipped cream using a spatula. Do this gently to avoid deflating the whipped cream.

Step 6

Taste the mousse and adjust sweetness or flavor as needed by adding a bit more powdered sugar or flavor extract. Fold in vanilla extract if using.

Step 7

Chill the mousse in the refrigerator for at least 30 minutes to allow it to set before using it as a cake filling.

Step 8

Use the mousse to fill your cake layers or as a topping or filling for cupcakes. Store leftovers in the refrigerator for up to 3 days.
