For the cake:

1 ½ cups (285g) granulated sugar

½ cup (118 ml) vegetable oil

3 large eggs

1 tablespoon (15 ml) pure vanilla extract

½ cup (118 ml) light sour cream

2 cups (280g) all-purpose flour

½ cup (55 g) cocoa powder

1 tablespoon (5g) espresso powder (optional)

2 ½ teaspoons (9 g) baking powder

½ teaspoon (2 g) baking soda

1 teaspoon (5 g) salt

1 ¼ cup (296 ml) brewed coffee

For the Strawberry filling:

2 cups (303g) strawberries, pureed

1 tablespoon (15 ml) lemon juice

2 tablespoons (24g) granulated sugar

1 tablespoon (8g), all-purpose flour, sifted

For the frosting

10 large egg whites

2 ½ cups (475 g) granulated sugar

3 cups (24 oz) unsalted butter, at room temperature

1 tablespoon (15ml) vanilla extract (or vanilla bean paste)

12 ounces (452 g) dark chocolate, melted


For the cake: 

Preheat the oven to 350°F. Prepare 3 8-inch round baking pans, line the bottom with parchment paper and grease the sides. Prepare your bake even stripes if desired.

In a large mixing bowl, combine the sugar, vegetable oil, eggs and vanilla extract. Beat on medium speed until the eggs and oil are well incorporated and the batter is lighter in color. Next mix in the sour cream and beat until well combined.

In a separate bowl, sift together the dry ingredients. Alternate half the dry ingredients followed by half of the coffee and mix just until the flour starts to incorporate. Repeat with remaining ingredients.

Use a spatula to scrape down the sides of the bowl and stir the batter from the bottom to the top to ensure it’s well mixed.

Divide the batter evenly between the three pans, about 1 2/3 cups of batter per pan. Bake at 350°F for 20-24 minutes. Rotate your pans in the oven halfway through baking.

Test the cake for doneness by inserting a toothpick into the center of the cake. If the toothpick comes out clean, your cake is done. Remove from the oven and allow to cool completely.

For the filling: 

Chop and puree the strawberries using an immersion blender or food processor.

In a medium-sized sauce pan, combine pureed strawberries, lemon juice sugar and flour stir well. Cook over medium-high heat until mixture starts to boil, stirring frequently.

Reduce heat and simmer for another 5 minutes, stirring occasionally until the strawberry puree starts to thicken. If the puree seems to thin, add up to 1 tablespoon of additional flour.

Allow the puree to cool completely, refrigerating to help speed up the process.

For the frosting: 

Wipe down the inside of your stainless-steel bowl with vinegar to remove any grease. Combine sugar and egg whites in the bowl with candy thermometer attached.

Set the bowl over top of a pot with 1 ¼ cups water covering the bottom. Place over medium heat.

Stir constantly with a whisk until the mixture reaches 140°-160° The sugar should be dissolved in the egg whites. You can test this by placing a drop on your finger tips and rubbing them together. The mixture should be completely smooth.

In a microwave-safe bowl, microwave the chocolate 50% power in 30-second increments, stirring each time until the chocolate is melted and smooth. Set aside to cool.

Immediately place the mixing bowl on your stand. Using the wire whisk attachment, beat the eggs white on low for 2 minutes than increase to medium high.

Beat for another 5 minutes. At this point, your frosting should have turned white and the body of the meringue starts to form. Increase the mixing speed to high. It will start to look glossy as the peaks begin to form. Beat for another 5-8 minutes until the bottom of your bowl is cool to the touch and your meringue has stiff peaks.

Turn your mixer down to medium-low. Slowly add your butter, 1 tbsp at a time. As you add more butter, the frosting might appear to have curdled and lost its body, that’s ok. Scrape down the sides of the bowl.

Switch to the paddle attachment, add the vanilla extract and continue beating on medium-high speed until your frosting starts to form. Slowly drizzle in the chocolate and continue beating until stiff peaks form, about 3-5 minutes.

To assemble this cake: 

level off your cakes by removing any domes. Place a dollop of frosting on your cake board and place the bottom layer of cake over that.

Pipe a thick boarder (a dam) along the outside edge of your cake. You may need to do this twice.

Spread half of the strawberry mixture over the cake, carefully filling the inside of the dam you created (so the sauce doesn’t leak out the sides)

Pipe another thin layer of frosting over the strawberry sauce and spread evenly with your offset spatula.

Add the second layer of cake and repeat the above steps using all of the remaining strawberry sauce. Next, add the final layer of cake on top

Use your piping bag to fill in any gaps between your layers and to create a crumb coat. Using an offset spatula or icing smoother, wipe away the excess frosting, leaving you just enough to coat the outside of the cake. Do not mix your crumb coating frosting back into your icing if it has cake debris in it.

Proceed to frost the top and sides of the cake using your offset spatula. Run your spatula around the outside edge of the cake while turning the turntable to create the indent in the frosting.

Use remaining frosting to pipe the florets on the top of the cake using an Ateco 846 tip (large open star). Garnish with strawberries if desired.
