How to Make Ina Garten Chocolate Mousse Cake
Making this delicious cake is easier than you might think! Let’s break it down into three simple phases.
Phase 1 – Prep (200 words)
- Preheat your oven to 350°F (175°C).
- Grease and flour a 9-inch round cake pan. This will help the cake come out smoothly after baking.
- In a mixing bowl, cream 1/2 cup of butter and 1 cup of sugar together until light and fluffy.
- Add in 2 eggs and 1 tsp of vanilla extract, mixing until combined.
- Sift together 1/2 cup of cocoa powder, 1 cup of flour, 1 tsp of baking soda, and 1/2 tsp of salt in another bowl.
- Gradually mix the dry ingredients into the wet ingredients, alternating with 1/2 cup of buttermilk and 1/2 cup of hot coffee until the batter is smooth.
Phase 2 – Cook/Assemble (200 words)
- Pour the cake batter into your prepared pan.
- Bake for about 30-35 minutes, or until a toothpick inserted in the center comes out clean. You want it to be soft but not wet!
- Once baked, let the cake cool in the pan for about 10 minutes, then transfer it to a wire rack to cool completely.
- While the cake cools, melt 8 oz of bittersweet chocolate with 2 tbsp of butter over a double boiler or in the microwave. Stir until smooth.
- In another bowl, whip the 3 egg whites until soft peaks form, then gradually add 1/4 cup of sugar until you reach stiff peaks.
Phase 3 – Serve (200 words)
- Gently fold the melted chocolate mixture into the whipped egg whites until combined.
- In a separate bowl, whip 1 cup of heavy cream until stiff peaks form. Fold this into the chocolate mixture.
- Once the cake has completely cooled, slice it in half horizontally to create two layers.
- Spread a layer of the chocolate mousse on the bottom layer and then place the top layer back on.
- Finally, spread the remaining mousse on top and around the sides of the cake for a beautiful finish.
- Chill in the refrigerator for at least 2 hours before serving. When you slice into it, the layers will reveal those gorgeous, creamy chocolate levels.
Pro Tips for the Best Results
- Use Room Temperature Ingredients: Make sure your butter, eggs, and buttermilk are at room temperature for better mixing.
- Don’t Overmix: Gentle folding of the chocolate into the egg whites keeps your mousse light and airy.
- Optional Espresso Powder: For an extra punch of flavor, mix a teaspoon of espresso powder into your batter.
- Watch the Baking Time: Every oven is different, so start checking your cake a few minutes early.
- Storage Tip: If you have leftovers, cover the cake tightly in the fridge. It stays delicious for up to 3 days!
- Chocolate Variations: Feel free to experiment with different types of chocolate, like semisweet or dark, depending on your preference.
- Serving Ideas: Garnish with fresh berries or a drizzle of chocolate sauce for an extra touch.
Common Mistakes to Avoid
- Not Greasing the Pan Properly: If you skip this step, your cake might stick and break apart when you try to remove it. Always grease and flour your pan to ensure a smooth release.
- Overbaking: Leaving the cake in the oven too long can lead to a dry texture. Start checking it a few minutes before the suggested time to get that soft, moist cake.
- Skipping the Chilling Step: If you cut into the cake right after assembling, the mousse won’t be set properly. Allow it to chill in the fridge to achieve that perfect, creamy consistency.
Recipe Variations
- Gluten-Free: Substitute all-purpose flour with a 1:1 gluten-free baking mix.
- Dairy-Free: Use plant-based butter and coconut cream to replace the heavy cream.
- Vegan: Use flax eggs and dairy-free chocolate for a plant-based version.
- Spicy Twist: Add a sprinkle of cayenne pepper to the chocolate batter for a hint of heat.
How to Serve Ina Garten Chocolate Mousse Cake
- Best Pairings: Serve with fresh berries, vanilla ice cream, or a dollop of whipped cream.
- Toppings: Drizzle with chocolate sauce or sprinkle with cocoa powder for an elegant touch.
- Garnishes: A few mint leaves can brighten up the presentation.
Make Ahead & Storage
Can I Meal Prep This?

Storing Leftovers

Freezing

Reheating
This cake is best served cold, but if you want to warm it up, use the microwave for about 15-20 seconds, stirring gently to ensure even heat.
FAQs
Can I use frozen cauliflower?
While this recipe doesn’t call for cauliflower, for other dishes, yes, frozen works perfectly!
How to make it extra creamy without cream?
You can use full-fat coconut milk for a creamy texture without heavy cream.
Can I double it?
Absolutely! Just make sure to adjust baking times and use a larger pan.
How to fix a too-thick mousse?
Gently fold in a bit more whipped cream or egg whites to lighten and loosen the mousse.
