How to Make Heart-Shaped Raspberry Mousse with a Brownie Base Recipe
Step 1: Prepare the Brownie Base
Start by preheating your oven to 350°F (175°C) and greasing a 9×13-inch pan lined with parchment paper. Combine the melted butter with granulated sugar, eggs, and vanilla extract, mixing until smooth. Then stir in the cocoa powder, flour, salt, and baking powder until just incorporated. Spread this rich batter evenly in the pan and bake for 20 to 22 minutes until a toothpick inserted comes out with moist crumbs. Let the brownie cool completely before cutting out heart shapes using a cookie cutter.
Step 2: Make the Raspberry Mousse
While the brownies cool, it’s time to create the airy raspberry mousse layer. Gently simmer the raspberries with sugar and lemon juice until soft and fragrant, then press through a sieve to remove the seeds, leaving you with a smooth puree. Meanwhile, sprinkle the gelatin over water to bloom, then stir it into the warm raspberry mixture until fully dissolved. Allow this to cool to room temperature, ensuring it won’t deflate your whipped cream.
Step 3: Whip and Fold
Beat the heavy cream and powdered sugar until soft peaks form, creating the perfect light base for your mousse. Carefully fold in the cooled raspberry puree, incorporating the flavors without losing the airy texture. This step is key to a mousse that holds its shape but still feels light and velvety.
Step 4: Assemble the Dessert
Place each heart-shaped brownie base into your silicone heart molds or use an acetate-lined cookie cutter on a flat tray. Spoon or pipe the raspberry mousse evenly over the brownie hearts, smoothing the tops gently for a clean finish. Chill the dessert for at least 4 hours until the mousse is fully set and ready to unmold.
Step 5: Unmold and Garnish
Carefully remove the mousse hearts from their molds, taking care not to lose their delicate shape. This final step is where your creativity shines—add fresh raspberries, a dollop of whipped cream, shaved chocolate, or even edible glitter for a sparkling touch that will wow whoever you share this dessert with.

Shaved dark chocolate offers a sophisticated bittersweet contrast, and a sprinkle of edible glitter can turn your dessert into a sparkling masterpiece fit for any special occasion.
Side Dishes
This dessert shines on its own but pairs beautifully with a scoop of vanilla bean ice cream or a drizzle of raspberry coulis on the side. For a more indulgent touch, serve alongside a rich espresso or a glass of chilled rosé to balance the sweet and tart flavors.
Creative Ways to Present
Serving these mousse hearts on individual dessert plates with a dusting of powdered sugar or cocoa powder around the edges creates an elegant look. You can also arrange multiple hearts on a large platter for a stunning centerpiece, or place them atop mini mirrors or wooden boards for a rustic yet refined vibe.
Make Ahead and Storage
Storing Leftovers
Once chilled and set, store any leftovers covered in the refrigerator for up to 2 days. Keeping them in airtight containers will preserve the mousse’s delicate texture and the brownie’s fudgy richness without drying out.
Freezing
This Heart-Shaped Raspberry Mousse with a Brownie Base Recipe is best enjoyed fresh but can be frozen if needed. Place the mousse hearts on a baking sheet to freeze individually before transferring to a sealed container. Thaw them overnight in the fridge before serving to maintain their texture and flavor.
Reheating
Since this dessert is served chilled, reheating isn’t recommended. Instead, allow frozen mousse hearts to thaw slowly in the refrigerator to preserve theirRefreshing taste and structure.
FAQs
Can I use frozen raspberries for the mousse?
Absolutely! Frozen raspberries work perfectly, especially when fresh ones aren’t in season. Just thaw them before cooking to get the best puree consistency.
What if I don’t have heart-shaped molds?
No worries! You can use a heart-shaped cookie cutter on the cooled brownies and assemble the mousse on top in a lined muffin tin or simply layer mousse on the brownie hearts on a tray, then chill.
How long does this dessert take to set?
The mousse requires at least 4 hours in the refrigerator to fully set, but overnight chilling is ideal for the best texture and flavor.
Can I make the brownie base ahead of time?
Yes, the brownie base can be baked a day or two in advance and stored wrapped airtight at room temperature, making the assembly easier on the day you want to serve.
Is this recipe suitable for vegetarians?
Yes, it is vegetarian-friendly as it contains no meat products, though it does include gelatin, so it’s not vegan.

Ingredients
Brownie Base
- 1/2 cup unsalted butter, melted
- 1 cup granulated sugar
- 2 large eggs
- 1 tsp vanilla extract
- 1/3 cup unsweetened cocoa powder
- 1/2 cup all-purpose flour
- 1/4 tsp salt
- 1/4 tsp baking powder
Raspberry Mousse
- 2 cups fresh or frozen raspberries
- 1/4 cup granulated sugar
- 1 tbsp lemon juice
- 1 tbsp water
- 1 tbsp unflavored gelatin
- 1 1/4 cups heavy whipping cream
- 1/4 cup powdered sugar
Optional Topping
- Fresh raspberries
- Whipped cream
- Shaved chocolate
- Edible glitter
Instructions
- Prepare the Brownie Base: Preheat your oven to 350°F (175°C). Grease and line a 9×13-inch baking pan with parchment paper. In a mixing bowl, combine the melted butter, granulated sugar, eggs, and vanilla extract. Mix well until smooth. Add in the cocoa powder, flour, salt, and baking powder, stirring until just combined. Pour the batter evenly into the prepared pan and bake for 20 to 22 minutes, or until a toothpick inserted in the center comes out with moist crumbs. Allow the brownies to cool completely.
- Cut Brownie Hearts: Once cooled, use a heart-shaped cookie cutter to cut out the brownie bases. Place each heart-shaped brownie into silicone heart molds or line the cookie cutter with acetate sheets and set them on a tray for the mousse layering.
- Make Raspberry Puree: In a saucepan over medium heat, combine raspberries, granulated sugar, and lemon juice. Simmer the mixture for 5 to 7 minutes until the raspberries have softened. Press the mixture through a fine sieve to remove seeds, collecting the smooth puree.
- Bloom Gelatin: In a small bowl, place the water and sprinkle the unflavored gelatin over it. Let it bloom for about 5 minutes until it thickens. Gently stir the bloomed gelatin into the warm raspberry puree until fully dissolved, then allow the mixture to cool to room temperature.
- Whip Cream: In a separate chilled bowl, beat the heavy whipping cream along with the powdered sugar until soft peaks form. Take care not to overbeat to maintain a light texture.
- Combine Mousse: Gently fold the cooled raspberry mixture into the whipped cream until smooth and uniform. This creates a light and airy raspberry mousse.
- Assemble and Chill: Spoon or pipe the raspberry mousse evenly over each brownie heart in the molds. Use a spatula to smooth the tops. Cover and chill the desserts in the refrigerator for at least 4 hours or until the mousse is fully set.
- Unmold and Garnish: Carefully remove the heart-shaped mousses from their molds. Decorate with fresh raspberries, whipped cream, shaved chocolate, or edible glitter as desired for a stunning presentation.
Notes
- Best made a day ahead for ease in serving and enhanced flavor melding.
- If heart-shaped molds are unavailable, use a parchment-lined muffin tin or layer the mousse directly on top of brownie hearts and chill.
- Ensure the mousse is properly chilled to set; overnight chilling improves texture.
- Handle gelatin carefully—fully dissolve in warm puree to avoid lumps in mousse.
