Moist pumpkin spice cake with a swirl of chocolate! Learn the easiest way to make marble cake with this Pumpkin Marble Cake recipe!
I love marble cakes because they’re two cakes in one!
This pumpkin marble cake has a base of moist pumpkin spice cake with a swirl of rich chocolate cake throughout. And I have the secret to perfectly marbled cakes!
Before I figured out how to swirl the batter, I used to either over or under-marble my cake batters. Instead of pretty marble cake, I would end up with muddied cake from the mixed batters or two separate batters in one cake. Neither was what I wanted.
But this simple marbling technique makes perfectly marbled cake every time. It makes nice patterns in the batter with very little effort. So you get moist pumpkin spice cake with ribbons of chocolate cake throughout.
How to make pumpkin marble cake
In a large bowl, whisk sugars, vegetable oil, and buttermilk together until well-combined. Add eggs, and whisk well after each addition.
Stir in the pumpkin puree and vanilla extract. Add flour, baking soda, baking powder, and salt. Whisk in just until combined.
Scoop out 1 1/2 cups of batter into a separate bowl. Whisk in cocoa powder, sugar, and buttermilk until just combined. Stir pumpkin spice into pumpkin cake batter.
Add 1 cup of pumpkin batter to the bundt pan.
Top the pumpkin batter with 1/4 cup chocolate batter. Add 1/2 cup pumpkin batter over the top of the chocolate batter.
Continue repeating layers to use up the remaining batter. Bake until a toothpick inserted near the center comes out clean, about 50-60 minutes.
Let the cake cool in the pan for 10 minutes before inverting onto the wire cooling rack.
- Generously grease the pan! Bundt cakes are notorious for sticking. I like to use a nonstick baking spray with flour, but greasing and flouring will also work.
- Don’t stir! Don’t stir the batter. If the batter is uneven in the pan, don’t spread the batter. Simply give the pan a couple taps on the counter to help it settle.
- Wire cooling rack: If you’re worried about the cake sticking to the wire cooling rack, give it a quick spritz with nonstick baking spray before using.
How to store
Store the cake, covered, at room temperature. The cake will keep for up to 4 days.
