8 oz semisweet chocolate, chopped
1 ¼ cups granulated sugar
3 large eggs
1 teaspoon vanilla extract
½ cup all-purpose flour
¼ teaspoon salt
½ teaspoon baking powder

For the Raspberry Mousse:

1 ½ cups fresh raspberries (or frozen, thawed)
2 tablespoons powdered sugar
1 cup heavy cream
1 teaspoon vanilla extract
1 packet unflavored gelatin (about 2 ½ teaspoons)
3 tablespoons water
3 oz white chocolate, melted

Ingredient Highlights

Semisweet Chocolate: Adds depth of flavor to the brownie base and complements the tangy raspberry mousse.
Fresh Raspberries: Provide a burst of freshness and color to the mousse, adding both flavor and visual appeal.
White Chocolate: Adds a smooth, sweet element to the raspberry mousse.
Gelatin: Helps the mousse set perfectly, giving it the desired texture.
Heavy Cream: Whipped to soft peaks, it creates the creamy, airy texture of the mousse.

Step-by-Step Instructions

Prepare the Brownie Base:

Preheat the Oven: Preheat the oven to 350°F (175°C). Grease and line a 9×9-inch baking pan with parchment paper.
Melt the Butter and Chocolate: In a saucepan over low heat, melt the butter and semisweet chocolate, stirring occasionally until smooth. Remove from heat and let it cool slightly.
Mix the Wet Ingredients: In a large mixing bowl, whisk together the sugar, eggs, and vanilla extract until combined. Slowly add the melted chocolate mixture and whisk until smooth.
Add Dry Ingredients: Sift the flour, salt, and baking powder into the wet ingredients and mix until fully incorporated.
Bake the Brownies: Pour the brownie batter into the prepared pan and bake for 25-30 minutes, or until a toothpick inserted into the center comes out with just a few crumbs. Let the brownies cool completely in the pan.

Prepare the Raspberry Mousse:

Puree the Raspberries: In a blender or food processor, puree the raspberries until smooth. Pass the puree through a fine-mesh sieve to remove the seeds, leaving just the raspberry liquid.
Sweeten the Puree: In a small bowl, mix the raspberry puree with powdered sugar. Set aside.
Dissolve the Gelatin: In a small bowl, add 3 tablespoons of water and sprinkle the gelatin over the surface. Let it bloom for 5 minutes. Then, gently heat it in the microwave for 15-20 seconds until dissolved.
Combine with Raspberry Puree: Add the dissolved gelatin to the raspberry puree and stir to combine.
Whip the Cream: In a separate bowl, whip the heavy cream and vanilla extract to soft peaks.
Fold in the Mousse: Gently fold the whipped cream into the raspberry mixture until fully combined.
Add the White Chocolate: Once the mousse is smooth, fold in the melted white chocolate for extra creaminess.

Assemble the Dessert:

Cut the Brownie Base: Once the brownies have cooled, use a heart-shaped cookie cutter to cut out heart shapes from the brownie base.
Fill with Mousse: Spoon the raspberry mousse over each heart-shaped brownie base, smoothing the top with a spatula.
Chill the Dessert: Refrigerate the mousse-filled brownies for at least 3 hours, or until the mousse is set.

Garnish and Serve:

Decorate: Before serving, top with fresh raspberries, chocolate shavings, or a dollop of whipped cream for an extra touch of elegance.

How to Serve

Heart Shaped Raspberry Mousse with a Brownie Base is a show-stopping dessert that can be served in many creative ways:

Additional Tips

Let the Brownies Cool Completely: To avoid a messy assembly, make sure the brownies are completely cool before cutting them into hearts.
Use Fresh Raspberries for Best Flavor: While frozen raspberries can be used, fresh raspberries provide a brighter, more vibrant flavor.
Gelatin Tip: Make sure the gelatin is completely dissolved before adding it to the raspberry puree to avoid clumps in the mousse.
Make Ahead: This dessert can be prepared the day before and refrigerated overnight for a convenient, hassle-free treat.
Customize the Garnish: Add your own spin to the presentation with edible flowers, a drizzle of raspberry coulis, or a sprinkle of powdered sugar.
