What is a Marble Cake?
A marble cake gets its name from the swirl of chocolate and vanilla batters that create a “marbled” appearance when baked. No two loaves look the same, which makes every cake unique and visually stunning once sliced. This version is baked in a loaf pan for a classic pound cake-style finish—soft, buttery, and rich in flavor.
Ingredients You’ll Need
Here’s everything you’ll need to make the best chocolate marble loaf cake at home:
- Granulated sugar – Adds sweetness and helps cream the butter for a fluffy texture.
- Salted butter – Adds flavor and richness. (Use unsalted if preferred and add ½ tsp salt.)
- Eggs – Room temperature eggs help bind and create a smooth batter.
- Pure vanilla extract – For that iconic vanilla flavor.
- Sour cream – Keeps the loaf moist and tender. (Don’t skip it!)
- Cake flour – Creates a lighter crumb than all-purpose flour.
- Baking soda – Gives the loaf its lift and perfect texture.
- Unsweetened cocoa powder – For the rich chocolate swirl.
- Boiling water – “Blooms” the cocoa to enhance its chocolatey depth.
✨ Pro Tip: Want to make your own cake flour? Replace 2 tablespoons of every cup of all-purpose flour with cornstarch, then sift well.
How to Create the Marble Effect
The gorgeous marbled design is easier than it looks! Just follow these simple steps:
-
Make the base batter – Start by creaming butter and sugar, then beat in eggs, vanilla, sour cream, and cake flour.
-
Divide the batter – Split the batter in two. Mix cocoa powder and boiling water into one portion to create the chocolate batter.
-
Layer in the loaf pan – Alternate spoonfuls of vanilla and chocolate batter into your greased loaf pan.
-
Swirl – Use a butter knife to gently swirl the batters together for a marbled effect.
-
Bake – Pop into the oven and bake until a toothpick comes out clean.
