How to Make Heart Shaped Raspberry Mousse and Brownies Recipe
Step 1: Prepare the Heart Shape Chocolate Brownie
Start by preheating your oven to 350 degrees F, so it’s ready when your batter is. In a medium bowl, cream the softened butter, sugar, and vanilla extract together until the mixture is light and fluffy—this is the base of your chewy brownie. Beat in the eggs one at a time, making sure each is fully incorporated before adding the next. Next, gently fold in the flour and cocoa powder until everything blends seamlessly. Finish the batter by mixing in the mini chocolate chips, just enough so they don’t sink to the bottom.
Step 2: Bake the Brownie Layer
Line a 9×13-inch cookie sheet with parchment paper, then spread the brownie batter evenly, about 1 inch thick. Pop it into the oven and bake for 12 to 15 minutes. You’ll know it’s ready when a toothpick inserted in the thickest part comes out with only a few moist crumbs. Once baked, give the brownie a solid 30 minutes to cool—this makes cutting out those perfect heart shapes so much easier and cleaner.
Step 3: Make the Heart Shape Raspberry Mousse
While the brownie cools, it’s mousse time. First, sprinkle the unflavored gelatin over cold water and let it bloom for 5 to 10 minutes—this step ensures your mousse sets beautifully. Meanwhile, heat frozen raspberries and sugar gently in a saucepan over medium-low heat, stirring until the fruit has melted into a luscious sauce. Remove from heat, stir in the bloomed gelatin until it dissolves completely, then strain the mixture through a sieve to remove seeds and get a silky smooth jelly base.
Step 4: Whip and Fold the Mousse
Once your raspberry sauce has cooled to room temperature, whip the heavy cream with powdered sugar and vanilla extract until stiff peaks form. Carefully fold the raspberry mixture into the whipped cream in batches, creating a perfectly airy yet flavorful mousse that’s just begging to fill those heart molds.
Step 5: Assemble and Freeze
Divide the raspberry mousse evenly into your heart-shaped molds. Then gently place the brownie hearts on top of each mousse portion. Transfer the molds to a cookie sheet and pop them into the freezer for about four hours or overnight to set fully. Patience here means you’ll get perfectly layered, elegant treats every time.
Step 6: Unmold and Enjoy
When you’re ready to serve, carefully remove the mousse and brownie hearts from the molds and let them sit at room temperature for 15 to 20 minutes. This final rest softens the mousse slightly, giving you a melt-in-your-mouth experience with every bite.
How to Serve Heart Shaped Raspberry Mousse and Brownies Recipe
Garnishes
Fresh raspberries and a sprinkle of powdered sugar bring a beautiful finishing touch that enhances the raspberry flavor and adds a delicate sweetness. A few mint leaves also add a lovely pop of color and freshness that complements the rich chocolate perfectly.
Side Dishes
This dessert pairs beautifully with a scoop of vanilla bean ice cream or a dollop of freshly whipped cream. For an adult twist, serve alongside a glass of sparkling rosé or your favorite dessert wine to elevate the celebration vibe.
Creative Ways to Present
Try serving the heart-shaped mousse and brownies on pretty dessert plates, accented with edible flowers or a drizzle of melted dark chocolate. You can also stack multiple hearts for an elegant tower or serve mini versions individually in clear cups for a stunning party presentation.
Make Ahead and Storage
Storing Leftovers
Leftover Heart Shaped Raspberry Mousse and Brownies Recipe treats should be stored in an airtight container in the refrigerator to keep the mousse fresh and the brownies moist. They will stay perfect for up to three days, making them a great make-ahead dessert for busy days.
Freezing
The mousse and brownies freeze beautifully when left in their molds or transferred to an airtight container. Keep them in the freezer for up to one month for a quick treat whenever the craving strikes. Just remember to thaw in the fridge for several hours before serving.
Reheating
Since this dessert shines best chilled, avoid reheating. Instead, let frozen pieces thaw slowly in the refrigerator or at room temperature to preserve their texture and flavor.
FAQs
Can I use fresh raspberries instead of frozen?
Absolutely! If fresh raspberries are in season, they work wonderfully. Just adjust the cooking time slightly to soften them into a sauce for the mousse. Frozen raspberries are great because they give you consistent flavor year-round.
Is it possible to make this recipe dairy-free?
Yes, you can substitute the butter with a dairy-free margarine and use coconut cream or another plant-based whipping cream for the mousse. The texture might vary slightly, but the flavor will still be delicious!
Can I use a regular pan instead of heart-shaped molds?
You can make this recipe without the molds by layering the brownies and mousse in a regular pan, then cutting into heart shapes later with a cookie cutter. The molds just make assembly and presentation effortless.
How long does it take for the mousse to set properly?
Plan at least 4 hours in the freezer, but overnight works best to ensure the mousse is firm and easy to unmold. Rushing this step could make the mousse too soft to handle.
Are there any tips for cutting the brownies into perfect hearts?
Yes! Make sure brownies are completely cooled before cutting. Use a sharp heart-shaped cookie cutter, pressing down firmly but gently. Wiping the cutter clean between cuts helps maintain clean edges.

- 2 eggs
- 3/4 cup all-purpose flour
- 1/2 cup unsweetened cocoa powder

- 2 cups frozen raspberries
- 1/3 cup sugar
- 1 cup heavy whipping cream
- 1/3 cup powdered sugar
- 1 tsp vanilla extract
- Heart shape silicone mold
Instructions
- Prepare Brownie Batter: In a medium bowl, combine softened butter, sugar, and vanilla extract. Mix until the mixture is light and fluffy. Beat in eggs one at a time until fully incorporated.
- Add Dry Ingredients: Gradually add the flour and cocoa powder to the wet mixture. Mix until the batter is smooth and consistent.
- Fold in Chocolate Chips: Gently mix in the mini semi-sweet chocolate chips to evenly distribute them in the batter.
- Bake Brownies: Line a 9×13 inch cookie sheet with parchment paper. Spread the batter evenly to about 1 inch thickness. Bake in a preheated oven at 350°F (175°C) for 12-15 minutes. Use a toothpick to check doneness; it should come out with only a few crumbs.
- Cool and Cut: Remove brownies from oven and let cool completely, about 30 minutes. Once cooled, cut out heart shapes using a cookie cutter.
- Bloom Gelatin: In a small bowl, combine unflavored gelatin with cold water. Let it sit for 5-10 minutes to bloom and absorb the liquid.
- Prepare Raspberry Sauce: In a saucepan over medium-low heat, cook frozen raspberries with sugar, stirring occasionally until the raspberries melt. Remove from heat, stir in the bloomed gelatin until dissolved. Strain the mixture through a sieve to remove seeds, pressing to extract all juice. Set aside and let cool to room temperature.
- Whip Cream: In a mixing bowl, whip heavy cream with powdered sugar and vanilla extract until stiff peaks form. This can be done with a hand mixer, stand mixer, or whisk by hand.
- Fold Raspberry Sauce into Whipped Cream: Gradually fold the cooled raspberry sauce into the whipped cream in 1/4 cup increments until fully combined, forming the raspberry mousse.
- Assemble Mousse and Brownies: Evenly divide the raspberry mousse into heart-shaped silicone molds. Place the brownie hearts on top of the mousse layer in each mold.
- Freeze: Transfer molds to a cookie sheet and freeze for at least 4 hours or overnight to set firmly. Do not invert molds yet.
- Serve: Remove the mousse and brownie hearts from molds. Let them sit at room temperature for 15-20 minutes before serving to soften slightly and enhance flavor.
Notes
- Use parchment paper for easy removal of brownies from the baking sheet.
- Ensure gelatin is fully dissolved in raspberry sauce to avoid lumps in mousse.
- You can substitute fresh raspberries if available, but frozen works best for the sauce.
- For firmer mousse, chill the mousse before adding brownie hearts in molds.
- Letting the dessert sit at room temperature before serving helps soften the mousse for best texture.
