How to Make Caramel Mousse Cake

Prepare the Caramel: In a heavy-bottom saucepan, heat 1 cup of granulated sugar over medium-low heat. Stir gently and melt until it turns a deep, rich caramel color.
Mix in Butter and Cream: Remove from heat, then slowly add 5 tablespoons of unsalted butter and ½ cup of heavy cream while stirring continuously. If it seizes, return to low heat until smooth again.
Add Salt and Vanilla: Stir in 1 teaspoon of sea salt and 1 teaspoon of vanilla extract off the heat. Allow the caramel to cool, then refrigerate it for thickness.
Preheat the Oven: Set your oven to 350°F (175°C). Line a 9-inch springform pan with parchment paper, or grease it well for easy removal.
Mix Dry Ingredients: In a large mixing bowl, combine 1 cup of all-purpose flour, 1 cup of granulated sugar, ½ cup of natural cocoa powder, 1 teaspoon of baking soda, ½ teaspoon of baking powder, and ½ teaspoon of kosher salt. Beat these ingredients together until well combined.
Combine Wet Ingredients: In another bowl, whisk together 1 large egg, ¼ cup of vegetable oil, ¼ cup of sour cream, ¼ cup of whole milk, and 1 teaspoon of vanilla extract until smooth.
Incorporate Coffee: Add ½ cup of hot coffee to the wet mixture and stir until everything is well blended. Don’t forget to scrape the bowl to ensure no flour clumps remain.
Bake the Cake: Pour the batter into your prepared pan and bake for 25-28 minutes. A toothpick inserted should come out clean with a few crumbs; let the cake cool in the pan.
Make the Caramel Mousse: In a bowl, beat together 1 cup of heavy cream and 1 teaspoon of vanilla extract until stiff peaks form. Set aside.
Blend Cheese and Caramel: In another bowl, mix 1 cup of cream cheese with ½ cup of salted caramel sauce until smooth. Gently fold in the whipped cream until it’s all combined.
Assemble the Cake: Once the cake is completely cool, spread the mousse over the top evenly. Refrigerate for about 6 hours or overnight to let it set perfectly.
Add Final Touch: After the mousse has set, pour ⅓ cup of salted caramel sauce on top and spread it gently for a delightful finish.

Optional: Garnish with chocolate shavings for an extra touch of elegance!

Caramel Mousse Cake Recipe FAQs

What should I look for when selecting ingredients for the caramel?
Absolutely! When selecting sugar for your caramel, opt for granulated sugar that is dry and free of clumps. For butter, high-quality unsalted butter will give you the best results. Make sure your heavy cream is at room temperature to prevent seizing during mixing, and choose pure vanilla extract for the richest flavor.

How should I store the Caramel Mousse Cake?
Once you’ve topped your cake with the mousse, refrigerate it for up to 3 days. Use an airtight container or cover it with plastic wrap to keep it fresh and prevent drying out. If you’re keeping it without the mousse, it can stay at room temperature for 1 day, covered.

Can I freeze the Caramel Mousse Cake?
Very! To freeze your cake, it’s best to do so before adding the mousse. Wrap it tightly in plastic wrap, followed by aluminum foil, and store it in the freezer for up to 2 months. When you’re ready to enjoy it, simply thaw in the fridge overnight, then add your mousse and serve!

What if my caramel becomes grainy?
Oh no, that can happen if the sugar crystallizes! If your caramel seizes, don’t panic. Simply return the pan to low heat while stirring gently until it melts back down to smooth. To avoid graininess, ensure your sugar is clear of impurities and don’t stir too much once it starts melting; letting it cook undisturbed helps.

Are there any dietary considerations for this cake?
Absolutely! If you are baking for someone with allergies, please note that this recipe includes dairy (heavy cream, butter, cream cheese, and sour cream) and gluten (from all-purpose flour). Feel free to substitute with non-dairy alternatives or gluten-free flour blends. Just ensure your salted caramel sauce is also free of allergens if necessary!
