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 flour, baking powder, baking soda, salt, cocoa powder, and sugar until evenly distributed.
03 - Add eggs, vegetable oil, milk, and vanilla extract to the dry mixture. Beat until smooth and no lumps remain.
04 - Gradually pour in hot water while mixing on low speed until fully incorporated. The batter will be thin.
05 - Divide batter evenly between the two prepared pans. Bake for 30–35 minutes, or until a toothpick inserted in the center comes out clean.
06 - Let cakes cool in pans for 10 minutes, then transfer to wire racks to cool completely before assembling.
07 - Combine sliced strawberries, sugar, and lemon juice in a small bowl. Set aside for 15 minutes, stirring occasionally until the strawberries release their juices.
08 - Place chopped chocolate in a heatproof bowl. Heat cream in a small saucepan until just boiling, then pour over chocolate. Let sit for 3 minutes, then stir until smooth. Allow to cool until thickened but still spreadable.
09 - Place one cake layer on a serving plate. Spread a thin layer of ganache over the top, then arrange the macerated strawberry slices evenly on top.
10 - Place the second cake layer on top. Spread the remaining ganache over the top and sides. Decorate with whole or halved strawberries and chocolate shavings if desired.
11 - Refrigerate for at least 30 minutes before slicing for cleaner cuts and set layers.
