- 1 teaspoon vanilla extract
- 1/3 cup (40g) unsweetened cocoa powder
- 1/2 cup (65g) all-purpose flour
- 1/4 teaspoon salt
- 1/4 teaspoon baking powder
For the Raspberry Mousse:
- 1 1/2 cups (180g) fresh raspberries (or frozen, thawed)
- 1/4 cup (50g) granulated sugar
- 1 teaspoon lemon juice
- 1 teaspoon unflavored gelatin
- 2 tablespoons cold water

How to Make Heart-Shaped Raspberry Mousse with a Brownie Base
Step 1: Prepare the Brownie Base
Start by preheating your oven to 350°F (175°C). Grease a 9-inch square baking pan and line it with parchment paper, leaving some overhang for easy removal.
In a medium bowl, whisk together the melted butter and granulated sugar until smooth. Add the eggs and vanilla extract, mixing until well combined.
Sift in the cocoa powder, flour, salt, and baking powder, then gently fold everything together until just combined. Be careful not to overmix—this keeps the brownies fudgy!
Pour the batter into the prepared pan and spread it evenly. Bake for 18-22 minutes, or until a toothpick inserted into the center comes out with a few moist crumbs. Let the brownie cool completely before proceeding to the next step.
Step 2: Cut Out Heart Shapes
Once your brownie base has cooled, use a heart-shaped cookie cutter to cut out heart-shaped pieces. If you don’t have a cutter, you can carefully trace a heart shape onto parchment paper and cut around it with a sharp knife. Set the brownie hearts aside.
Step 3: Make the Raspberry Puree
In a small saucepan over medium heat, combine the raspberries, granulated sugar, and lemon juice. Stir occasionally, allowing the raspberries to break down and release their juices.
After about 5 minutes, remove from heat and press the mixture through a fine-mesh sieve to remove the seeds. You should be left with a smooth raspberry puree. Set it aside to cool.
Step 4: Bloom the Gelatin
In a small bowl, sprinkle gelatin over cold water and let it sit for 5 minutes to bloom. This step helps the gelatin dissolve smoothly without clumps.
After blooming, warm the gelatin mixture in the microwave for 10-15 seconds until it becomes liquid. Stir it into the cooled raspberry puree.
Step 5: Whip the Cream
In a large mixing bowl, beat the heavy whipping cream and powdered sugar until stiff peaks form. Be careful not to overwhip—it should be light and fluffy.
Gently fold the raspberry puree into the whipped cream, using slow, sweeping motions to keep the mousse airy.
Step 6: Assemble the Desserts
Place each brownie heart on a serving plate or small dessert dish. Using a piping bag or spoon, carefully spread or pipe the raspberry mousse over each brownie heart, smoothing the tops with a spatula.
Refrigerate for at least 2 hours, or until the mousse is firm and set.
Step 7: Garnish and Serve
Just before serving, top each dessert with fresh raspberries, chocolate shavings, or a dollop of whipped cream. Serve chilled and enjoy!

Helpful Tips
- Use a good-quality cocoa powder for the best chocolate flavor in the brownies.
- Chill the mixing bowl before whipping the cream—it helps it whip faster and hold its shape better.
- Make it in advance – The mousse sets beautifully overnight, making this a great make-ahead dessert.
- Experiment with flavors – Swap raspberries for strawberries or mix in a bit of vanilla bean for an extra layer of flavor.
