CHOCOLATE VANILLA MARBLE CAKE
This Chocolate Vanilla Marble Cake is typically what we call a “Gâteau régréssif” in French – meaning it makes you feel like a kid again.
Here is the loaf I make over and over again, whenever I yearn for that taste from my childhood. It’s buttery, moist, tender and eye-catching with its pretty chocolate-vanilla swirls.

A Gâteau Marbré is traditionally baked in a loaf tin in France, which I think is a great way to showcase the marbled swirls. It’s a great recipe to have in your baking repertoire, as it is both delicious and classically suited for any occasion – be it a child’s “goûter” (after-school snack) or a fancier tea time gathering.
This is a simple recipe, but you need to be very precise with weighing your ingredients. As with many French baking recipes, I strongly recommend using a scale (we the French measure everything in grams). This is especially important for the eggs – you need 165g exactly.

INGREDIENTS:
- 2/3 cup (150g) unsalted butter, at room temperature
- 1 cup (200g) sugar
- 165g eggs (3 eggs)
- 2 cups (235g) flour
- 1 ½ tsp baking powder
- ½ tsp baking soda
- ¼ tsp kosher salt
- ¼ cups (60g) milk
- 2 tsp (8.5ml) vanilla extract
- 3 tsbp (22g) unsweetened cocoa powder + 1 tbsp (15ml) milk
INSTRUCTIONS:
- Preheat oven to 390°F (200°C). Grease a 9×5-inch loaf pan with butter and dust with flour.
- Using a spatula or a whisk, cream butter and sugar together until light and fluffy. Add in the eggs and mix until well incorporated.
- In a separate bowl, sift together the flour, baking powder, baking soda and salt. Combine with the wet ingredients, and mix until just incorporated. Add in the 60g of milk, and mix until just incorporated.
- Divide the batter in two separate bowls. In the first bowl, stir in the vanilla extract. In the second bowl, stir in the cocoa powder with one tablespoon of milk.
- Using a large spoon, dollop about 1/3 of a cup of the vanilla batter into the prepared pan and spread it evenly along the bottom. Using another large spoon, dollop the same amount of chocolate batter in the middle, and spread it out (pushing it down slightly in the middle and leaving some of the vanilla cake mix visible all around the edges). Repeat with a layer of vanilla cake mix, and then a layer of chocolate cake mix (always pushing the batter slightly in the middle, and leaving some of the batter underneath visible around the edges – to create that wavy marbled pattern when sliced). Repeat, alternating the layers, until all the batter is used. To create marbling, run a sharp knife through the batter in a swirling motion.
- Bake for 10 minutes. Lower the heat to 350°F (180°C) and bake for 40 minutes, until a cake tester comes out clean.
- Transfer to a cooling rack, and let cool at least 15 minutes before slicing.
- This cake is delicious warm or cool. You can keep it for up to 3 days on your kitchen counter, well wrapped in foil.
