Mix up the white cake ingredients according to package directions.

Take out 1/3rd of the batter out and mix in 3-4 drops of red food color to it.

Bake it in a well greased 7×3-inch loaf pan. This might take a little less time than instructed.

Remove from pan and let cool. Cut the cake into slices. Cut heart shapes from slices.

Spread a touch of the white cake batter to the bottom of greased 9×5 pan as a ‘glue’ to stick the hearts together. Carefully align the hearts. Then pour the rest of the batter on top of the hearts to cover them well. You may have more batter than required. Try not to overfill the pan. Bake according to the directions in box. Let cool.

Place chocolate in a large bowl. Heat 1 teaspoon butter and 1/2 cup heavy whipping cream in a saucepan over medium heat until butter is melted. Pour cream mixture over chocolate and whisk until smooth. Set aside until cooled, but still pourable, about 20 minutes.

Pour the ganache over the cake and refrigerate it for half an hour. Cut into slices and delight your loved ones with the heart shaped surprise that peeks out from inside!
