Cinnamon Mocha Sheet Cake Recipe

Preheat oven to 350 degrees F (175 degrees C). Grease a 10x15-inch jelly roll pan.

Melt 1 cup butter in a saucepan over medium heat. Whisk in 1/3 cup cocoa powder water and espresso powder; mix until smooth.

Combine white sugar brown sugar flour 1 1/2 teaspoon cinnamon and baking soda in a mixing bowl. Pour in the butter-cocoa mixture vanilla extract 1/2 cup milk and eggs. Mix until fully incorporated. Pour the batter into the prepared baking sheet

Bake in the preheated oven until the cake springs back when touched lightly with a finger about 18 minutes. Cool the cake in the pan on a wire rack.

To make the icing melt 1/4 cup butter in a saucepan or in the microwave. Transfer melted butter to a mixing bowl. Whisk in 3 tablespoons cocoa powder coffee 1/2 teaspoon cinnamon and 1 tablespoon milk. Slowly mix in the sifted confectioners' sugar and beat until smooth; add milk as needed to reach the consistency you like. Spread the icing over the cooled cake. For easier serving score the icing before cutting the cake: mark lines as a guide before you start to cut and divide the cake into 32 pieces.
