Set your oven to 350°F (175°C). Grease two 8- or 9-inch round cake pans and line the bottoms with parchment paper. This will make it easier to take the cakes out later.

In a medium bowl, sift together the cake flour, cocoa powder, baking powder, baking soda, and salt. Once combined, set this bowl aside.

In a big mixing bowl, beat the softened butter with both granulated sugar and dark brown sugar until it turns light and fluffy. This usually takes about 2 to 3 minutes.

Add the eggs one at a time, mixing well after each one. Then pour in the vanilla extract and mix until everything is smooth.

Stir in the sour cream and vegetable oil first, then add the milk. Mix everything until well combined.

Slowly add the dry mixture to the wet batter in two or three parts, mixing gently each time. Finally, stir in the hot coffee (or hot water). Don’t worry if the batter looks thin that’s how it’s supposed to be.

Pour the batter evenly into the two prepared pans. Bake for about 30 to 35 minutes. To check if they’re done, poke a toothpick in the center if it comes out clean, they’re ready. Let the cakes cool in their pans for 10 minutes, then move them onto a wire rack to cool completely.

In a small saucepan, combine the strawberries, sugar, and lemon juice. Cook over medium heat until the strawberries release their juices, about 5 to 7 minutes. Add the cornstarch and cook for another 1 to 2 minutes until it thickens a bit. Let this cool completely.

Heat the heavy cream until it’s hot but not boiling, either on the stove or in the microwave. Pour the hot cream over chopped dark chocolate and let it sit for a minute. Stir until smooth and then let it cool a little. In another bowl, beat the cream cheese until smooth, then add powdered sugar and vanilla extract and beat again. Finally, mix in the cooled chocolate mixture until it’s creamy and spreadable.

Place one cake layer on your serving plate. Spread a thick layer of the strawberry filling on top. Put the second cake layer over it. Cover the whole cake top and sides with the chocolate cream cheese frosting. Add fresh strawberries or any decoration you like, and you’re done!
