01 - Preheat oven to 350°F. Grease and line two 8-inch round cake pans with parchment paper.
02 - In a large bowl, whisk together the flour, baking powder, baking soda, salt, cocoa powder, and sugar until evenly distributed.
03 - Add the eggs, vegetable oil, milk, and vanilla extract to the dry mixture. Beat until smooth and well combined.
04 - Gradually pour in the hot water, mixing on low speed until fully incorporated. The batter will appear thin — this is normal.
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.
06 - Allow the cakes to cool in their pans for 10 minutes, then transfer to wire racks to cool completely.
07 - Combine the sliced strawberries, sugar, and lemon juice in a bowl. Let the mixture sit for 15 minutes, stirring occasionally, until the strawberries release their juices.
08 - Place the chopped chocolate in a heatproof bowl. Heat the cream in a small saucepan until it just begins to boil, then pour it over the chocolate. Let sit for 3 minutes, then stir until smooth and glossy. Allow to cool until thickened but still spreadable.
09 - Place one cooled cake layer on a serving plate. Spread a thin, even layer of ganache over the top, then arrange the strawberry slices on top of the ganache.
10 - Place the second cake layer on top. Spread the remaining ganache over the top and sides of the cake. Decorate with whole or halved strawberries and chocolate shavings as desired.
11 - Refrigerate the assembled cake for at least 30 minutes before slicing to ensure clean, even cuts.
