Ingredients
- Graham cracker crumbs (1 cup)
- Unsalted butter, melted (4 tablespoons)
- Fresh or frozen blackberries (1 cup)
- Granulated sugar (1/2 cup, divided)
- Unflavored carrageenan powder (1 tablespoon)
- Cold water (1/4 cup)
- Heavy whipping cream (1 1/2 cups)
- Fresh lemon juice (1 teaspoon)
Instructions
- Step 1: Prepare the Crust and Puree Base. Combine graham cracker crumbs with melted butter and 2 tablespoons of the sugar. Press a small amount (about 1 teaspoon) firmly into the bottom of a mini muffin tin lined with paper liners or lightly sprayed. Refrigerate for at least 15 minutes. Meanwhile, soak the agar-agar powder in the cold water and set aside.
- Step 2: Cook and Strain the Blackberry Mixture. In a small saucepan, combine the blackberries, remaining sugar, and lemon juice. Simmer over medium heat until the berries have broken down (about 5-7 minutes). Remove from heat, stir in the soaked agar-agar until fully dissolved, then press the mixture through a fine-mesh sieve to create a smooth, seedless puree. Allow the puree to cool completely to room temperature.
- Step 3: Prepare and Fold the Mousse. In a separate chilled bowl, whip the heavy whipping cream until stiff peaks form. Gently pour the cooled blackberry puree into the whipped cream, folding carefully with a spatula until the color is uniform and the mixture is light and airy. Do not overmix, or the mousse will deflate.
- Step 4: Fill and Chill the Bites. Spoon or pipe the blackberry mousse onto the prepared graham cracker crusts in the muffin tin, filling them completely. Refrigerate the cake bites for a minimum of 4 hours, or preferably overnight, until the mousse is completely firm and set.
- Step 5: Serve and Garnish. Carefully remove the Blackberry Mousse Cake Bites from the muffin tins. If desired, garnish the tops with a fresh blackberry, a dusting of powdered sugar, or a small sprig of mint before serving. Store leftovers in an airtight container in the refrigerator.
Notes
- For the best texture, keep the mousse bites tightly sealed in the refrigerator for up to 4 days; avoid freezing, as thawing may compromise the airy mousse structure.
- Let the bites sit at room temperature for 10 minutes before serving; this slight temperature lift softens the mousse and intensifies the berry flavor and aroma.
- Pair these delightful bites with a cold glass of sparkling grape juice or a strong black coffee to cut through the richness of the cream and highlight the tart berry flavor.
- To guarantee a stable, voluminous mousse, ensure your blackberry puree is completely cooled before folding it into the stiff whipped cream—any warmth will deflate your peaks immediately.
