Indulge in pure bliss with this heavenly Raspberry White Chocolate Mousse that strikes the perfect balance between tart berries and creamy white chocolate. This elegant dessert transforms simple ingredients into cloud-like mousse layered with vibrant homemade raspberry sauce, creating a show-stopping treat that looks like it came from a French patisserie but is surprisingly simple to make in your own kitchen.
I first created this recipe for my sister's bridal shower, and it was such a hit that it's become my go-to dessert for special occasions. The lightness of the mousse paired with the bright raspberry sauce creates this magical moment where the flavors dance on your tongue - it's truly something special.
Essential Ingredients and Selection Tips
- White Chocolate: Choose high-quality white chocolate containing cocoa butter (at least 30%) - check the ingredients list to avoid compounds or candy coating. Ghirardelli or Lindt white chocolate bars work beautifully
- Heavy Cream: Look for cream labeled as 'heavy whipping cream' with at least 36% fat content for the best stability and texture
- Fresh Raspberries: Select plump, bright berries without any signs of mold or mushiness. They should be deep red and fairly firm
- Frozen Raspberries: If using frozen, choose whole unsweetened berries for better control over the final sweetness
- Powdered Sugar: Sift before measuring to prevent any lumps in your mousse
- Vanilla Extract: Pure vanilla extract adds depth to both the mousse and sauce
- Lemon Juice: Fresh is best - it brightens the raspberry sauce perfectly
- Cornstarch: Regular cornstarch works fine, but look for a non-GMO version if that's important to you
Detailed Step-by-Step Instructions
- Preparing the Raspberry Sauce (20 minutes):
- Place 2 cups raspberries in a medium saucepan. Add 1/4 cup sugar and 2 tablespoons water. Cook over medium heat, stirring occasionally until berries break down (about 8-10 minutes). In a small bowl, whisk 1 tablespoon cornstarch with 2 tablespoons cold water. Slowly stir cornstarch mixture into simmering berries. Continue cooking until sauce thickens (about 2-3 minutes). Add 1 teaspoon lemon juice and stir. Strain through a fine-mesh sieve if desired (recommended for smoother texture). Cool completely before using.
- Creating the White Chocolate Base (15 minutes):
- Chop 8 ounces white chocolate into small, uniform pieces. Heat 1/4 cup heavy cream until just simmering (tiny bubbles around the edges). Pour hot cream over chocolate and let stand for 2 minutes. Whisk gently until completely smooth. Let cool to room temperature, stirring occasionally.

Growing up in a pastry-loving family, I discovered that white chocolate can be quite temperamental. Through countless attempts at perfecting this mousse, I've found that choosing quality white chocolate makes all the difference - not just in taste, but in how smoothly it incorporates into the cream.
Creating the Perfect Texture
The secret to achieving that cloud-like consistency lies in proper folding techniques. I've learned through trial and error that patience is key - rushing this step can deflate all the air you've carefully whipped into the cream. Start by ensuring your ganache has cooled to room temperature but remains fluid. Too warm and it'll deflate the whipped cream; too cool and you'll end up with white chocolate chunks throughout your mousse. The perfect temperature should feel neither warm nor cool when touched to your lip.
