Piano Cake

Whip the eggs with sugar until pale and fluffy.

Add the milk and butter, whip again.

Fold in the flour, cocoa, baking powder, and vanilla, mixing until smooth.

Grease a baking pan, pour in the batter, and bake in a preheated 350°F oven for about 35 minutes.

Let the cake cool slightly.

Mix milk with cocoa and soak the cake evenly, making sure there are no dry spots. Let it sit so the soak is fully absorbed.

For the frosting: combine milk, sugar, and flour in a saucepan, place over medium heat, and stir constantly until thickened. Remove from heat, cool, add heavy cream, and whip until smooth.

Spread the frosting evenly over the cake surface and sprinkle with coconut flakes.

Lay parchment strips parallel on top, spacing them evenly, dust the exposed areas with cocoa, then carefully remove the strips.
