Preheat the oven to 350°F (175°C). Grease and flour the two 9-inch round cake pans.
In a large mixing bowl, combine the flour, granulated sugar, cocoa powder, baking powder, baking soda, and salt. Whisk together until well mixed.
Add the eggs, milk, vegetable oil, and vanilla extract to the dry ingredients. Mix with an electric mixer on medium speed for about 2 minutes until the batter is smooth.
Stir in the boiling water. The batter will be thin, which is normal. Divide the batter evenly between the two prepared cake pans.
Bake for 30-35 minutes or until a toothpick inserted in the center comes out clean. Allow the cakes to cool in the pans for 10 minutes, then turn them out onto a cooling rack to cool completely.
While the cakes are cooling, prepare the whipped cream. In a mixing bowl, combine the heavy whipping cream and powdered sugar. Beat with an electric mixer until soft peaks form.
Once the cakes are completely cooled, place one cake layer on a serving plate. Spread a layer of whipped cream on top, then add half of the sliced strawberries.
Place the second layer of cake on top. Spread the remaining whipped cream over the top and sides, then arrange the remaining strawberries on top.
If desired, garnish with chocolate shavings for an extra touch.
Slice and serve your chocolate cake with strawberries. Enjoy!
