In this tutorial, we learn how to make a chocolate cake from scratch. You will need: sugar, cooking chocolate, white flour, black coffee, butter, orange juice, orange peel, eggs, and baking powder to make this cake. First, melt the chocolate into the coffee in a pot over low heat. Then, beat the sugar and butter until fluffy. Add in the eggs while whipping one by one. Then, stir in the chocolate mixture and mix until combined. After this, sift the flour and baking soda inside it and whip well. When combined, add in the orange peel and then bake in a cake pan. Bake in the oven for 45 minutes, then make the frosting with sugar, butter, egg yolk, coffee, and orange juice. Whip this all together, then ice the cake when it's finished and enjoy!
