Raspberry Chocolate Fudge Cake

Many wonderful things happen in March…. Daylight Savings Day, St. Patrick’s Day, and my good friend SIJIA’S BIRTHDAY!! I wanted to make her a birthday cake that is as wonderful as she is. This raspberry chocolate fudge cake, with a rich chocolate buttercream, and raspberry filling seemed perfect for the occasion.

Chocolate Cake:

  • 3 cups all-purpose flour
  • 3 cups sugar
  • 1 1/3 cup cocoa
  • 3 tsp baking powder
  • 2 tsp baking soda
  • 2 tsp salt
  • 1 tsp espresso powder
  • 1 1/2 cups milk
  • 3/4 cup vegetable oil
  • 3 eggs
  • 3 tsp vanilla extract
  • 1 1/2 cups boiling water

Chocolate Buttercream Frosting:

  • 1½ cups butter (3 sticks), softened
  • 1 cup cocoa
  • 5 cups confectioner’s sugar
  • 1/2 cup milk
  • 2 tsp vanilla extract
  • 1/2 tsp espresso powder

Raspberry Filling:

  • 24 oz frozen unsweetened raspberries, thawed
  • 1/2 cup sugar
  • 1 tsp lemon juice
  • 2 heaping tablespoons cornstarch

Step 1: Make the Cake Layers

Preheat oven to 350º F. Prepare four 7-inch cake pans or 3 8-inch cake pans by spraying with baking spray or buttering and lightly flouring.

For the cake batter, add flour, sugar, cocoa, baking powder, baking soda, salt and espresso powder to a large bowl.

Add milk, vegetable oil, eggs, and vanilla to flour mixture and mix together on medium speed until well combined. Carefully add boiling water to the cake batter.

Beat on high speed for about 1 minute (to add air to the batter). Distribute cake batter evenly between the four prepared cake pans.

Bake for 30-35 minutes, until a toothpick or cake tester inserted in the center comes out clean. 

Remove from the oven and allow to cool for about 10 minutes, remove from the pan and cool completely.

Step 2: Make the Chocolate Frosting

While the cake is baking, prepare the chocolate frosting. 

Add cocoa to a large bowl. Cream together butter and cocoa powder, until combined.

 Add the sugar and milk to cocoa mixture, alternating between 1 cup of sugar, and about a tablespoon of milk.

After each addition has been combined, turn mixer to a high speed for about a minute.

Repeat until all sugar and milk have been added. Mix in the vanilla extract and espresso powder. 

If the frosting appears too dry,  add more milk until it reaches the right consistency. If it appears to wet, or does not hold its form, add more confectioner’s sugar, a tablespoon at a time until it reaches the right consistency.

Step 3: Make the Raspberry Filling

The last step is the raspberry filling, which will be layered on top of the chocolate buttercream between layers.

Thaw the raspberries and strain juice from berries, reserve half the berries in a separate bowl (to be added between the cake layers during assembly). 

Add enough water to the juice to get 3/4 cup of liquid. In a small saucepan, combine raspberry juice/water, sugar, lemon juice, and cornstarch.  Cook over medium heat, whisking constantly, until mixture bubbles and thickens.  Remove from heat, set aside.

Step 4: Assemble this Raspberry Chocolate Fudge Cake

To assemble the cake, alternate between cake layer, chocolate  buttercream, and raspberry filling. Add 1/3 of the thawed raspberries on top of each layer of raspberry filling. Repeat until you reach the top cake layer, then apply a thin crumb coat of frosting.

Let the cake chill in the fridge for 30 minutes until the crumb coat is firm, then apply a thicker layer of frosting.

I decided to do elegant pulls of chocolate frosting up the sides the cake, and then top the entire top of the cake with fresh raspberries and a sprinkle of powdered sugar.

The end result? An elegant chocolate raspberry fudge cake that perfectly matches the birthday girl 😀

When you say butter in ingredients is it salted or unsalted

So I'm a little confused. You thaw all the berries, but you never say what to do with half of the thawed berries. One half you layer on top of the filling as you are layering your cake. But what about the other half? Was it supposed to go in the filling while cooking?

Hi Summer,

The reserved raspberries get added between the cake layers, on top of the raspberry filling. Hope that helps, happy baking!
