Ingredients

¾ cup unsalted butter (room temperature)
2 oz semi-sweet chocolate (chopped)
½ cup all-purpose flour
½ cup Dutch processed cocoa powder
½ teaspoon kosher salt
¾ cup granulated sugar
½ cup light brown sugar (packed)
3 large eggs (room temperature)
2¼ teaspoon powdered gelatin (1 packet)
2 tablespoons water
3 cups fresh raspberries (two 6oz packs)
¼ cup granulated sugar
1 cup heavy whipping cream (very cold)
¼ cup powdered sugar
6 oz semi-sweet chocolate (chopped)
1¼ cups heavy whipping cream (300ml)

Instructions

Step 1: Preheat the oven to 350℉ and grease and line a 9″ round springform pan. Coat the inside with nonstick spray, then line the bottom and sides completely with parchment paper to prevent sticking.
Step 2: In a microwave-safe bowl, melt the butter and 2 oz chopped chocolate in 30-second intervals, stirring until smooth. Set aside to cool.
Step 3: In a separate bowl, whisk together the flour, cocoa powder, and salt.
Step 4: In a large bowl, whisk the granulated sugar, brown sugar, and eggs vigorously for 3 minutes until frothy.
Step 5: Add the cooled chocolate mixture to the eggs and sugar, whisking to combine.
Step 6: Sift in the dry ingredients and fold gently with a rubber spatula until just combined.
Step 7: Pour the batter into the prepared pan, spread evenly, and bake for 25-30 minutes. Allow the cake to cool completely.
Step 8: For the raspberry mousse, puree the raspberries and pass through a fine mesh sieve into a saucepan. Scrape the sieve to extract all juice.
Step 9: Sprinkle gelatin over water in a small bowl and let stand for 5 minutes to bloom.
Step 10: Heat the raspberry puree with ¼ cup sugar over medium heat until simmering and sugar dissolves. Remove from heat and stir in the gelatin until fully dissolved.
Step 11: Transfer the raspberry mixture to a shallow bowl to cool to room temperature, stirring occasionally for about 20-30 minutes.
Step 12: Whip the cold heavy cream with powdered sugar in a stand mixer on medium speed until it thickens, then increase to high speed until stiff peaks form.
Step 13: Gently fold half the cooled raspberry puree into the whipped cream, then fold in the remaining half until evenly combined.
Step 14: Pour the mousse over the cooled brownie cake and smooth the surface. Refrigerate covered for at least 4 hours, preferably overnight.
Step 15: For the ganache, place chopped 6 oz chocolate in a heat-proof bowl. Heat 1¼ cups cream until steaming and pour over the chocolate.
Step 16: Let sit for 1 minute, then stir until smooth. Cool the ganache, stirring occasionally, until pourable but not hot (about 10 minutes).
Step 17: Remove the cake from the springform pan and peel off parchment. Place the cake on a wire rack over a sheet pan to catch drips, using parchment handles to move it easily.
Step 18: Pour the ganache slowly onto the center of the cake, letting it drip down the sides to cover completely.
Step 19: Once set, use the parchment handles to transfer the cake to a serving platter. Clean any ganache smudges on the platter.
Step 20: Top the cake with fresh raspberries, slice, and serve.

Tips & Variations

Use ripe, fresh raspberries for the best flavor in the mousse and as cake topping.
If you prefer a less intense chocolate flavor, substitute half the Dutch cocoa powder with natural cocoa powder.
For a dairy-free option, substitute coconut cream for heavy cream and use dairy-free chocolate.
Make the cake a day ahead to allow the mousse to set fully for the best texture.

Storage

Store the cake covered in the refrigerator for up to 3 days. Keep it well wrapped to prevent drying out. Reheat slices at room temperature for about 20 minutes before serving, but ganache should remain cool and firm.

How to Serve

Serve this delicious recipe with your favorite sides.

FAQs

Can I use frozen raspberries for the mousse?

Yes, you can use frozen raspberries. Thaw them completely and strain well to remove excess liquid before making the puree.

How do I know when the whipped cream is at stiff peaks?

When you lift the whisk, the cream should hold a sharp peak that doesn’t fold or collapse. It should stand firmly while still being smooth and airy.

Brownie Cake

¾ cup unsalted butter (room temperature)
2 oz semi-sweet chocolate (chopped)
½ cup all-purpose flour
½ cup Dutch processed cocoa powder
½ teaspoon kosher salt
¾ cup granulated sugar
½ cup light brown sugar (packed)
3 large eggs (room temperature)

Raspberry Mousse

2¼ teaspoons powdered gelatin (1 packet)
2 tablespoons water
1 cup heavy whipping cream (very cold)
¼ cup powdered sugar

Chocolate Ganache Glaze

6 oz semi-sweet chocolate (chopped)
1¼ cups heavy whipping cream (300 ml)

Instructions

Prepare the springform pan: Preheat the oven to 350℉. Grease and line a 9″ round springform pan by coating the inside with nonstick spray. Then, cover the bottom with a round parchment paper and line the sides with parchment strips to prevent sticking.
Melt butter and chocolate: Place butter and chopped chocolate in a microwave-safe bowl and melt in 30-second increments, stirring between each, until smooth. Set aside to cool.
Mix dry ingredients: Whisk together flour, Dutch cocoa powder, and kosher salt in a separate bowl.
Whisk sugars and eggs: In a large bowl, vigorously whisk granulated sugar, brown sugar, and eggs for 3 minutes until the mixture is frothy.
Combine chocolate mixture: Pour the cooled melted chocolate and butter into the egg mixture and whisk until fully combined.
Add dry ingredients: Sift the dry ingredients over the wet mixture and gently fold in using a rubber spatula until just combined.
Bake the brownie base: Pour batter into the prepared pan, spread evenly, and bake for 25-30 minutes. Remove from oven and cool completely.
Make raspberry puree: Blend fresh raspberries into a puree, then press through a fine mesh sieve into a medium saucepan, scraping to extract all the juice.
Bloom gelatin: In a small bowl, sprinkle gelatin over water and let it stand for 5 minutes to soften.
Heat raspberry puree: Place the puree on medium heat, stir in granulated sugar until dissolved and the mixture simmers. Remove from heat.
Add gelatin to puree: Stir the gelatin mixture into the warm raspberry puree until fully dissolved. Transfer to a shallow bowl and let cool to room temperature, stirring occasionally for about 20-30 minutes.
Whip cream: Using a stand mixer, whip cold heavy cream and powdered sugar at medium speed until it starts to thicken. Increase to high speed and beat until stiff peaks form.
Combine mousse: Add half of the cooled raspberry puree to whipped cream and mix on medium-low speed. Add remaining puree and mix again until fully incorporated.
Assemble mousse layer: Pour the raspberry mousse evenly over the cooled brownie base, smoothing to the edges. Refrigerate covered for at least 4 hours or overnight for best results.
Prepare ganache glaze: Chop the semi-sweet chocolate and place in a heatproof bowl. Heat heavy cream until steaming with bubbles around edges, then pour over chocolate. Let sit for 1 minute and stir until smooth.
Cool ganache: Stir ganache occasionally and let it cool for about 10 minutes until it is pourable but no longer hot.
Remove cake from pan: Carefully remove the cake from the springform pan and peel off all parchment paper. Transfer cake onto a wire rack with a strip of parchment underneath for handling. Place a sheet pan below to catch drips.
Glaze cake: Pour the ganache slowly over the center of the cake, allowing it to cover the sides completely. Let ganache set until firm.
Transfer and decorate: Use the parchment handles to move the cake to a serving platter. Clean any spills, and top with fresh raspberries.
Serve: Slice and serve chilled for the best texture and flavor combination.

Notes

Make sure the parchment paper fully lines the springform pan to prevent sticking.
Use room temperature eggs and butter for a smoother batter.
Blooming the gelatin properly is essential to avoid lumps in the mousse.
Whip the cream to stiff peaks but do not overbeat to avoid curdling.
Refrigerate the assembled cake overnight for the mousse to fully set and flavors to meld.
Use fresh raspberries for topping to enhance freshness and presentation.
