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 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 combined.
04 - Gradually add the dry ingredients to the wet mixture, mixing just until combined. Stir in the hot brewed coffee until smooth. The batter will be thin — this is normal.
05 - Divide the batter evenly between the two prepared pans. Bake for 30–35 minutes, or until a toothpick inserted in the center comes out clean. 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, add the butter, and whisk gently until smooth and glossy. Cool to room temperature.
07 - Beat the whipping cream with powdered sugar until stiff peaks form. Set aside in the refrigerator.
08 - Place one cake layer on a serving plate. Spread a thin layer of strawberry jam if using, top with half the whipped cream, and arrange sliced strawberries evenly over the cream.
09 - Place the second cake layer on top. Pour and spread the ganache over the top, allowing it to drip down the sides. Decorate with extra fresh strawberries. Chill for 30–60 minutes before serving.
