Chocolate Orange Truffle Cake

Chocolate and orange are one of those pairings that just work. This chocolate orange truffle cake brings them together in a rich and elegant dessert.

The cake itself is flourless, so it comes out dense and fudgy like a real truffle. It’s naturally gluten free too, which is a nice bonus.

On top, there’s a smooth chocolate ganache that melts in your mouth. A little of it drips down the sides, which makes the whole thing look bakery worthy.

The final touch is a light orange cream made with mascarpone. It adds a fresh, citrusy note that balances all the deep chocolate flavor.

It looks fancy, but each part is simple to put together. I’ll walk you through it step by step so nothing feels stressful.

Recipe Ingredients

For the Flourless Cake

• 10 oz Bittersweet Chocolate, Chopped
• 3/4 cup Unsalted Butter
• 5 Large Eggs
• 3/4 cup Granulated Sugar
• 1/4 cup Unsweetened Cocoa Powder
• 1 tbsp Orange Zest
• 1 tsp Pure Vanilla Extract
• 1/4 tsp Fine Sea Salt

For the Ganache

• 8 oz Bittersweet Chocolate, Chopped
• 3/4 cup Heavy Cream
• 1 tbsp Light Corn Syrup
• 1 tsp Orange Zest

For the Orange Cream

• 4 oz Mascarpone Cheese
• 1 cup Heavy Cream
• 1/4 cup Powdered Sugar
• 1 tbsp Orange Zest
• 1/2 tsp Pure Vanilla Extract

For the Finish

• 1 oz Dark Chocolate, Shaved

Directions

Step 1

Heat the oven to 325 F. Grease an 8-inch springform pan, line the bottom with parchment paper and wrap the outside securely with foil.

Step 2

Melt the bittersweet chocolate and butter together over low heat, stirring until smooth. Remove from the heat and stir in the cocoa powder, orange zest, vanilla and salt.

Step 3

Beat the eggs and granulated sugar for 4 to 5 minutes, until pale, thick and tripled in volume. Gently fold in the chocolate mixture in three additions.

Step 4

Pour the batter into the pan and bake for 30 to 35 minutes, until the edges are set and the center remains slightly soft. Cool completely, then refrigerate for 2 hours before releasing the cake from the pan.

Step 5

Heat the cream for the ganache until steaming and pour it over the chocolate, corn syrup and orange zest. Let it stand for 2 minutes, then stir until glossy and cool until slightly thickened.

Step 6

Spread the ganache over the chilled cake, allowing a small amount to flow down the sides. Refrigerate for 30 minutes to set.

Step 7

Beat the mascarpone, heavy cream, powdered sugar, orange zest and vanilla to firm peaks. Spoon the orange cream over the cake and finish with shaved dark chocolate.

My Tips

Beat the Eggs Until They Triple in Size

This is the most important step for the whole cake. Since there’s no flour, the beaten eggs are what give the cake its structure and light texture.

Beat the eggs and sugar for the full 4 to 5 minutes until they turn pale, thick, and grow to three times their starting size. If you stop too early, the cake will come out dense and flat instead of tender.

You’ll know it’s ready when you lift the beater and the mixture falls back in a slow ribbon that sits on top for a second before sinking in.

Fold in the Chocolate Gently

After all that work beating the eggs, you don’t want to knock the air back out. That’s why you add the chocolate in three separate additions instead of dumping it in all at once.

Use a soft, sweeping motion from the bottom up and stop as soon as you don’t see any streaks. From my experience, folding slowly keeps the batter fluffy and gives you that melt-in-your-mouth center.

One thing to watch for is the chocolate temperature. Let the melted chocolate and butter cool for a few minutes first, because if it’s too hot it will deflate the eggs and start cooking them.

Take It Out While the Center Is Still Soft

This cake is meant to stay a little wobbly in the middle when it comes out of the oven. The edges should look set, but the center will still jiggle slightly when you gently shake the pan.

It keeps setting as it cools and chills, so pulling it out at 30 to 35 minutes is exactly right. If you wait for the center to look fully firm, you’ll end up with a dry, cakey texture instead of a rich, fudgy one.

Frequently Asked Questions

What kind of chocolate works best for this cake?

Bittersweet chocolate is the way to go because it gives the cake a rich, deep flavor that balances out the sweetness from the sugar and cream. Look for something in the 60 to 70 percent range for the best results.

You can use semisweet if that is what you have, but the cake will taste a little sweeter overall. Try to use a good quality bar chocolate rather than chips, since chips have added stabilizers that can make everything less smooth.
