(Light sponge + silky chocolate buttercream + caramel top perfection!)

🌟 Introduction

Some cakes are simple desserts… and some are masterpieces that leave everyone speechless.
This Caramel Chocolate Sponge Cake belongs to the second category — light, airy sponge layers filled with rich chocolate buttercream and crowned with a shiny, golden caramel topping.

Every bite is a perfect blend of soft, creamy, and crunchy textures. This is the kind of cake that makes people ask for the recipe before they even finish their slice.

If you’re ready to impress your guests, your family, or even yourself — this is the recipe you’ve been waiting for.

📜 A Little History

The origins of sponge cakes go all the way back to the 18th century in Europe, where beaten eggs were used to leaven cakes before baking powder existed. Over time, the sponge cake became beloved worldwide for its lightness and versatility.

Chocolate buttercream has French roots — a luxurious mixture used in patisserie for centuries — while caramel has been adored since the early 1700s for its golden sweetness.
This recipe combines all three classics into one unforgettable dessert.

🧬 Formation of the Cake (How the Layers Work Together)

The sponge cake forms the airy base. The whipped egg whites create a delicate structure that holds everything together.
The chocolate buttercream adds richness, moisture, and depth of flavor.
The caramel topping creates a glossy, slightly crisp finish that gives the cake its dramatic final touch.

Together, these layers form a cake that is visually stunning and irresistibly delicious.

🛒 Ingredients

🎂 Sponge Cake

6 eggs, separated
3/4 cup sugar (150 g)
3/4 cup cake flour or all-purpose flour (100 g)
1 tsp vanilla
Pinch of salt

🍫 Chocolate Buttercream

1 cup butter, softened (225 g)
1 cup powdered sugar (120 g)
4 oz dark chocolate, melted (120 g)
3 egg yolks
1 tsp vanilla

🍯 Caramel Top

3/4 cup sugar (150 g)
2 tbsp water
1 tbsp butter

👩‍🍳 Instructions / Method

⭐ Step 1 — Make the Sponge Cake

Preheat oven to 350°F (175°C).
Separate the eggs into whites and yolks.
Beat the egg whites with a pinch of salt until soft peaks form.
Add half the sugar and continue beating until stiff peaks form.
In another bowl, beat the egg yolks with the remaining sugar until pale and creamy.
Add vanilla.
Gently fold the egg yolk mixture into the whites.
Sift in the flour and fold slowly to avoid deflating the batter.
Pour into a lined or greased cake pan.
Bake 20–25 minutes until the top is lightly golden.
Let cool completely before frosting.

⭐ Step 2 — Make the Chocolate Buttercream

Beat softened butter until light and fluffy.
Add powdered sugar gradually and keep beating.
Add melted dark chocolate and mix well.
Add vanilla and egg yolks.
Beat until smooth, creamy, and silky.

Optional: Chill for 10 minutes if you want a firmer texture.

⭐ Step 3 — Make the Caramel Top

⚠️ Be careful — hot caramel can burn skin.

In a saucepan, combine sugar and water.
Cook over medium heat without stirring.
When it turns amber-colored, remove from heat.
Stir in 1 tbsp butter for shine.
Quickly pour the caramel over the top of the cake (or over parchment to create a decorative disk).

You can swirl it thin or make a hard caramel sheet — your choice!

⭐ Step 4 — Assemble the Cake

Slice the sponge cake into 2–3 layers.
Spread chocolate buttercream between each layer.
Frost the outside lightly or heavily — your preference.
Finally, add the caramel topping while warm so it sets beautifully.
