Decadent Berry Cloud Cake With Tangy Lemon Mousse: Your Blissful Ultimate Summer Indulgence

A Refreshing Dessert That Will Make You Rethink Fruit Cakes

Have you ever wondered why most berry cakes feel too dense or too sweet — or why they lack that fresh, zingy pop that screams summer?

You’re not alone.

According to a 2023 Statista report, over 58% of home bakers said they struggle to balance flavor and texture when baking with fresh fruit. This Berry Cake with Lemon Mousse solves that beautifully by combining light, airy yellow cake with a tangy lemon mousse and a colorful medley of juicy berries.

The result? A multi-layered masterpiece that tastes like sunshine on a plate.

Whether you’re hosting a backyard brunch, celebrating a birthday, or just craving a guilt-free indulgence, this cake has it all — visual appeal, balanced flavor, and a melt-in-your-mouth texture.

Ingredients List: A Colorful Symphony of Freshness

This Berry Cake with Lemon Mousse recipe calls for fresh, seasonal fruit, bright lemony notes, and the kind of mousse that makes people pause mid-bite. Here’s what you need:

Yellow Cake Base

▢ 1 baked yellow cake (baked in three 8-inch round pans)

Tip: You can use a boxed yellow cake mix or make your own from scratch. The homemade version tends to be fluffier and less sweet, which pairs well with the tart mousse.

Berry Filling & Garnish

▢ 2 cups fresh raspberries (about 12 ounces)
▢ 2 cups fresh blueberries (about 12 ounces)
▢ 2 cups fresh blackberries (about 12 ounces)
▢ 16 ounces fresh strawberries, sliced

Substitution Ideas: Use frozen berries only if they’ve been completely thawed and drained. For a tropical twist, add sliced kiwi or mango.

Lemon Mousse Filling

▢ 6 large eggs (3 whole eggs, 3 yolks, 3 whites)
▢ 1 cup + 2 tablespoons granulated sugar
▢ 2 teaspoons lemon zest
▢ ½ cup fresh lemon juice (from 3–4 lemons)
▢ Pinch of salt
▢ 1 cup heavy whipping cream

Pro Tip: Always use fresh lemon juice — bottled versions tend to be bitter and flat.

Step-by-Step Instructions

Step 1: Bake the Cake Rounds

Preheat your oven to 350°F (175°C). Prepare your yellow cake batter using a box mix or your favorite homemade recipe. Divide evenly among three 8-inch round cake pans. Bake for 16–22 minutes, or until a toothpick inserted into the center comes out with moist crumbs. Let the cakes cool completely. Wrap and refrigerate if making ahead.

Step 2: Make the Lemon Mousse

Fill a large saucepan with a few inches of water and bring to a simmer. In a heatproof bowl, whisk together: 3 whole eggs, 3 egg yolks, 1 cup sugar, lemon zest, lemon juice, and a pinch of salt. Place the bowl over the simmering water (double boiler style) and stir constantly with a wooden spoon for 12–15 minutes until thickened slightly. Remove from heat. Let sit for 15 minutes, then cover with plastic wrap directly on the surface. Chill in the fridge for 1–2 hours.

Step 3: Fold in Egg Whites

In a clean bowl, beat the 3 reserved egg whites until frothy. Add the remaining 2 tablespoons of sugar and continue beating until stiff peaks form. Gently fold into the chilled lemon curd base.

Step 4: Add Whipped Cream

In a separate bowl, whip the heavy cream until stiff peaks form. Carefully fold it into the lemon mixture. Chill mousse for 30 more minutes or until ready to use.

Step 5: Assemble the Cake

Place one cooled cake round on a serving plate. Spread ½ – ⅔ cup of mousse evenly, leaving a 1-inch border around the edge. Top with a mix of berries. Repeat with the remaining layers, stacking as you go. Garnish the top with the remaining fruit. Chill for at least 30 minutes before slicing.
