Ingredients for Mini Blueberry Mousse Cakes
Gather these items:
- For the Crust:
- 1 cup graham cracker crumbs
- 1/4 cup unsalted butter (melted)
- 2 tablespoons granulated sugar
- For the Blueberry Mousse:
- 1 cup fresh or frozen blueberries (plus extra for garnish)
- 1/4 cup granulated sugar
- 1 teaspoon lemon juice
- 1 teaspoon gelatin powder
- 2 tablespoons water (for gelatin)
- 1 cup heavy cream (whipped)
- 1 teaspoon vanilla extract
How to Make Mini Blueberry Mousse Cakes Step-by-Step
- Step 1: Preheat your oven to 350°F (175°C).
- Step 2: In a medium bowl, combine the graham cracker crumbs, melted butter, and granulated sugar. Mix until the crumbs are evenly coated.
- Step 3: Spoon the mixture into the bottom of mini tart pans or muffin tins, pressing down firmly to create an even layer.
- Step 4: Bake the crusts in the preheated oven for about 8–10 minutes or until lightly golden. Remove from the oven and let cool completely.
- Step 5: In a small saucepan, combine the blueberries, sugar, and lemon juice. Cook over medium heat until the blueberries start to break down and release their juices, about 5–7 minutes. Remove from heat and let cool slightly.
- Step 6: In a small bowl, sprinkle the gelatin over the water and let it bloom for about 5 minutes. Then, gently heat until dissolved (you can use the microwave for about 10 seconds).
- Step 7: Once the blueberry mixture has cooled, blend it until smooth. Strain through a fine mesh sieve to remove skins if desired.
- Step 8: Stir the dissolved gelatin into the blueberry puree until well combined.
- Step 9: In a separate bowl, whip the heavy cream until soft peaks form. Gently fold the whipped cream into the blueberry mixture until fully incorporated.
- Step 10: Spoon or pipe the blueberry mousse into the cooled crusts, filling them to the top.
- Step 11: Cover and refrigerate the mini cakes for at least 4 hours or until the mousse is set.
- Step 12: Once set, garnish with fresh blueberries on top.
- Step 13: Carefully remove the mini cakes from the molds and serve chilled.
