01 - Preheat oven to 350°F (175°C). Grease two 8-inch round cake pans and line the bottoms with parchment paper rounds. Lightly flour the sides.
02 - In a medium bowl, sift together the all-purpose flour, cocoa powder, baking powder, baking soda, and salt. Whisk to ensure even distribution and set aside.
03 - In a large mixing bowl, beat the eggs with granulated sugar and brown sugar using an electric mixer on medium-high speed until the mixture is pale, light, and creamy, about 3 to 4 minutes. Pour in the vegetable oil, whole milk, and vanilla extract, mixing until fully incorporated.
04 - Gradually add the sifted dry ingredients to the wet batter in three additions, mixing on low speed just until each addition is incorporated. Do not overmix. Stir in the hot brewed coffee last; the batter will be quite thin and that is expected.
05 - Divide the batter evenly between the two prepared cake pans, smoothing the tops with a spatula. Bake on the center rack for 30 to 35 minutes, or until a wooden toothpick inserted into the center of each layer comes out clean. Let the cakes cool in their pans for 10 minutes, then turn them out onto a wire rack to cool completely.
06 - Place the finely chopped semi-sweet chocolate in a heatproof bowl. In a small saucepan, heat the heavy cream over medium heat until it just begins to simmer around the edges—do not let it boil. Pour the hot cream over the chocolate and let it sit undisturbed for 3 minutes. Add the butter, then whisk gently from the center outward until the ganache is smooth, glossy, and free of lumps. Set aside to cool to room temperature, stirring occasionally, until it reaches a spreadable consistency.
07 - In a chilled mixing bowl, beat the heavy whipping cream with the powdered sugar using an electric mixer on medium-high speed until stiff peaks form. Be careful not to overwhip. Refrigerate until ready to assemble.
08 - Place the first cake layer on a serving plate. Spread a thin, even layer of strawberry jam over the top. Dollop half of the whipped cream over the jam and spread gently. Arrange the sliced strawberries in an even layer over the cream. Place the second cake layer on top and press down gently to settle it.
09 - Pour the room-temperature ganache over the top of the assembled cake, using a spatula to guide it evenly over the surface and allow it to drip naturally down the sides. Arrange the remaining whole strawberries on top for garnish. Refrigerate the finished cake for 30 to 60 minutes before slicing to allow the ganache to set and the flavors to meld.
