This homemade Marble Cake is so moist and and buttery. Easy marble cake recipe with deep chocolate flavors. Every bite is chocolatey and sweet. 5 stars.
Beat well after each addition of egg until creamy. Scrape down the sides and add in vanilla extract. Fold the flour into the mixture and mix well. Add in the milk.
Divide the batter into two portions. Stir the cocoa powder into one portion and mix well. Transfer the plain batter into the greased baking pan. Shake it lightly to distribute evenly.
Pour the cocoa batter in the middle of baking pan, and lightly swirl the cocoa batter with a butter knife. I usually make a "S" shape with the butter knife a few times. Do not over mix.
Bake until golden brown and cooked, about 40 minutes. If the top turns too brown before the cake is set, cover the top with aluminum foil at 20 minutes mark to prevent the top from being too brown and crusty.
Insert a cake tester in the middle of the cake to test doneness. Bake longer if the middle of the cake is still wet. Remove it from the oven and let cool on the wire rack for 5 minutes. Remove from pan, slice and serve immediately.
