How to Make Marble Cake
Follow along with our step-by-step pictures, instructions, and expert tips to make the perfect swirl cake. We’ve got tricks to help you get the best swirl and texture every time. Let’s get started!
FIRST STEP: Preheat the oven to 325°F. Spray two 9-inch round cake pans with non-stick cooking spray, or use the wrappers from the butter to grease them thoroughly.
SECOND STEP: In one large bowl, combine the white or yellow cake batter ingredients: cake mix, butter, eggs, sour cream, buttermilk, and vanilla extract.
Beat on low speed for 1 minute and then on medium-high speed for two additional minutes. Set aside.
THIRD STEP: In a separate bowl, combine the chocolate cake batter ingredients: chocolate cake mix, butter, eggs, sour cream, buttermilk, and vanilla extract.
Beat on low speed for 1 minute and then on medium-high speed for two additional minutes.
FOURTH STEP: Using an ice cream scoop or large spoon, pile dollops of cake batter into the pans, rotating between the white and chocolate batter.
Fill the pans about ⅔ of the way full to prevent overflowing. You may not use all of the batter, depending on your pan.
Pro Tip
I filled my pans quite full (¾ of the way full) to use up all the batter. I baked the cakes with a sheet pan on the shelf underneath in the oven to catch any spills. The cakes puffed over the rim.
If you have deeper 9-inch cake pans, you can use those. I like the extra height on the cakes by filling the pans really full. You can just trim any overage with a bread knife before frosting.
FIFTH STEP: Use a butter knife to cut through the batter and swirl the two colors. Do not over-swirl, which can result in the colors blending.
Pro Tip
The marble effect comes from swirling the two cake colors into each other.
There isn’t a specific pattern or movement; just let your knife flow all the way down to the bottom of the pan and swirl a few times in curved strokes throughout the batter.
SIXTH STEP: Bake for about 40 minutes or until a toothpick inserted into the cakes comes out with just a few crumbs (the pans are going to be fuller than with a single cake mix, so the bake time will likely be 5 to 10 minutes longer than indicated on the box of cake mix.
SEVENTH STEP: Cool the cakes for 10 to 15 minutes and then remove the cakes from the pans and let them cool completely on a wire rack.
Pro Tip
Freeze cake layers before frosting to make them firmer and easier to assemble and frost.
Wrap with plastic wrap once cooled completely and then place in the freezer for 1 hour or up to 1 week.
No need to defrost before assembling and frosting the cake.
EIGHTH STEP: Meanwhile, prepare the frosting. Chop the German chocolate baking bar into small pieces.
Use a double boiler or 30-second increments in the microwave to melt the chopped chocolate. Stir until fully melted and set aside to cool.
NINTH STEP: Use a whisk to stir together the cocoa powder and hot water (or hot cream) until smooth and shiny.
TENTH STEP: In a large mixing bowl using a hand mixer or in the bowl of a stand mixer, beat together the softened butter, cooled melted chocolate, cocoa powder mixture, and powdered sugar.
Beat until the butter mixture is fully combined and fluffy.
ELEVENTH STEP: Level the tops of the cakes (and any lip from overfilled cake pans) with a serrated knife.
TWELFTH STEP: Using an offset spatula, frost the bottom cake layer with about ½ cup of chocolate frosting.
THIRTEENTH STEP: Stack the second cake layer on top of the first, top side down.
FOURTEENTH STEP: Frost the top and sides of the cake with the remaining frosting.
Pro Tip
The frosting can be chilled in the refrigerator if it is too soft or if you wish to prepare it in advance.
Give it another quick beat with a hand or stand mixer before using it to frost the cake.
The frosting is not shelf-stable – meaning that the cake should be kept chilled until serving and for storage.

Baked this one yesterday and I really liked how visible the chocolate & vanilla swirls were. Texture was moist enough, not dry like some marble cakes I’ve had. My kids thought it looked fancy when I sliced it too.
