It doesn't get easier than this marble cake recipe. Perfect for a cozy afternoon snack. Topped with a rich chocolate glaze, this is the best marble cake I've ever had!
Grease and line a 9x5 loaf pan with parchment paper.
Following the instructions on the cake box, combine the ingredients necessary to make the yellow cake batter. In my case, I used 3 eggs, water and vegetable oil.
Scoop out 1 cup of the yellow batter and add the cocoa powder, dark cocoa powder and chocolate chips. Mix to combine.
Pour half the yellow cake batter into a prepared 9x5 loaf pan. Spoon in the chocolate batter over the yellow batter, and make swirls using a knife or skewer. Don't over mix!
Add the remaining yellow batter and swirl one more time.
Bake following directions on the box. Allow to cool before adding the chocolate sauce.
For the Chocolate Sauce:
In a microwave safe bowl, combine the chocolate chips and coconut oil. Heat in 30 second increments, mixing in between until the chocolate is fully melted. Allow to cool a bit before pouring over the cake. It will set within an hour.
