Marble Cake

Ingredients

white cake batter
liquid carmine (for coloring)
finely grated sweet chocolate (for coloring)

Directions

Prepare the white cake batter as usual.
In a separate bowl, mix a portion of the batter with liquid carmine to achieve a bright pink color.
In another bowl, mix a portion of the batter with finely grated sweet chocolate to achieve a brown color.
In a cake mold, alternate filling with portions of the white, pink, and brown batters, but do not layer them.
Using a small stick, gently drag through the dough in a zig-zag pattern to create a marbled effect.
