01 - Preheat oven to 350°F. Grease and line two 8-inch round cake pans with parchment paper.
02 - In a bowl, whisk together the all-purpose flour, cocoa powder, baking powder, baking soda, and salt until evenly distributed.
03 - In a large bowl, beat the eggs with granulated sugar and brown sugar until light and creamy. Mix in the vegetable oil, whole milk, and vanilla extract until well blended.
04 - Gradually add the dry ingredients to the wet mixture, mixing just until combined. Stir in the hot brewed coffee until the batter is smooth. The batter will be thin—this is expected.
05 - Divide the batter evenly between the two prepared pans. Bake for 30 to 35 minutes, or until a toothpick inserted into the center comes out clean. Let the cakes cool in the pans for 10 minutes, then transfer to a wire rack to cool completely.
06 - Place the finely chopped semi-sweet chocolate in a heatproof bowl. Heat the heavy cream in a small saucepan until just simmering, then pour it over the chocolate. Let sit for 3 minutes, then add the unsalted butter and whisk gently until the ganache is smooth and glossy. Allow it to cool to room temperature.
07 - Beat the whipping cream with the powdered sugar using an electric mixer until stiff peaks form. Set aside.
08 - Place one cake layer on a serving plate. Spread a thin layer of strawberry jam over the top if desired. Add half of the whipped cream and arrange the sliced strawberries evenly over the cream. Place the second cake layer on top.
09 - Pour the ganache over the top of the assembled cake, allowing it to drip down the sides naturally. Decorate with additional fresh strawberries. Chill the cake for 30 to 60 minutes before serving to allow the layers to set.
