👩‍🍳 How to Make Chocolate Ganache Cake

1. Prepare the Oven

Preheat the oven to 350°F (175°C).

Grease and line two 8-inch round cake pans with parchment paper.

2. Mix the Dry Ingredients

In a large bowl, whisk together:

• Flour
• Cocoa powder
• Sugar
• Baking powder
• Baking soda
• Salt

3. Mix the Wet Ingredients

In another bowl, whisk together:

• Eggs
• Buttermilk
• Oil
• Vanilla

4. Combine

Add the wet ingredients to the dry ingredients.

Mix until mostly combined.

5. Add the Hot Coffee

Slowly pour in the hot coffee.

The batter will become relatively thin. That’s normal.

Mix just until smooth.

6. Fill the Pans

Divide the batter evenly between the prepared cake pans.

7. Bake

Bake for approximately 28–33 minutes.

A toothpick inserted into the center should come out clean or with a few moist crumbs.

8. Cool

Let the cakes cool in the pans for about 10 minutes.

Turn them out onto wire racks and cool completely.

🍫 How to Make Chocolate Ganache

1. Chop the Chocolate

Place the chopped chocolate in a heat-safe bowl.

2. Heat the Cream

Warm the heavy cream until steaming but not boiling.

3. Pour Over the Chocolate

Pour the hot cream over the chocolate.

Let it sit for approximately 2–3 minutes.

4. Stir

Stir gently from the center outward until smooth and glossy.

Add the butter if using.

5. Let It Thicken

Allow the ganache to cool until it reaches a spreadable consistency.

For pouring over the cake, use it slightly warmer.

For filling and frosting, let it cool longer.

🎂 Assemble the Cake

1. Level if Needed

If the cake layers are strongly domed, trim them gently with a serrated knife.

2. Add the First Layer

Place one cake layer on a cake stand.

Spread a layer of ganache over the top.

3. Add the Second Layer

Place the second cake layer on top.

4. Cover with Ganache

Pour or spread the remaining ganache over the top and sides.

Allow it to flow naturally rather than trying to make every edge perfectly smooth.

5. Set

Let the cake sit until the ganache firms slightly before slicing.

✨ Variations

Raspberry Chocolate Ganache Cake

Add a thin layer of raspberry preserves between the cake layers.

Espresso Chocolate Cake

Add espresso powder to the batter and ganache.

Salted Chocolate Ganache Cake

Finish the ganache with a tiny amount of flaky sea salt.

Chocolate Orange

Add fresh orange zest to the cake batter.

Single-Layer Ganache Cake

Bake the batter in one deeper pan and serve as a simpler single-layer cake.

🔥 Tips for the Best Chocolate Cake

Measure flour carefully. Too much flour can make the cake dry.

Don’t skip the coffee. It intensifies the chocolate flavor without making the cake taste strongly of coffee.

Don’t overmix. Mix only until the batter is smooth.

Cool the cake completely. Warm layers will melt the ganache.

Use chopped chocolate for ganache. It generally melts more evenly than large chocolate chips.

Let ganache cool before spreading. If it’s too warm, it will run straight off the cake.

Use a warm knife for clean slices. Wipe it between cuts.

❄️ Storage

Room Temperature

If your kitchen is cool, the cake can sit covered at room temperature for approximately 1 day.

Refrigerator

Store covered in the refrigerator for up to 4 days.

Let slices sit at room temperature briefly before serving for a softer texture.

Freezer

Unfrosted cake layers freeze very well.

Wrap them tightly and freeze for up to approximately 2 months.

Thaw before adding ganache.
