Chocolate and Vanilla Zebra Cake

Directions

1. 1In a bowl, combine the eggs and the sugar, and beat with an electric mixer until creamy and fluffy. Add the butter and vanilla and stir well.
2. 2Gradually add the flour with the baking powder and the buttermilk, and beat well until homogeneous.
3. 3In a separate bowl, combine the cocoa and the water and mix well. Add slightly more than 1/3 of the cake batter to the cocoa and stir well, thus obtaining two batters, yellow vanilla and brown chocolate.
4. 4Preheat oven to 360°F.
5. 5Grease a bundt pan or angel food cake pan with butter and sprinkle with flour.
6. 6Gradually add 2 tablespoons of the yellow batter to the pan, followed by 1 tablespoon of dark batter on top, repeating the layers/spoonfuls until both batters are used up.
7. 7Bake the cake until cooked (or until a toothpick inserted into the center comes out clean).
8. 8When the cake is almost done, prepare the syrup by melting the chocolate pieces with the milk on low heat, stirring constantly until the chocolate melts. Let the syrup cool for about 10 minutes before pouring it on the cake (and after removing the cake from the pan).
9. 9For the buttermilk, mix 1 cup of milk with 2 tablespoons of lemon juice, and let it sit for 15 minutes before using.
