This Marble Cake is irresistibly soft, fluffy, and moist, with a stunning swirl of vanilla and chocolate. It’s surprisingly easy to make and tastes every bit as amazing as it looks!
Ingredients
1½ cups all-purpose flour
1/4 cup cocoa (carob powder)
1 tsp baking soda
1 cup fine sugar
1 cup milk (at room temperature)
1/3 cup cooking oil (sunflower or canola)
1 tbsp vanilla extract
1 tbsp vinegar (lemon juice)
Method:
In a large mixing bowl, whisk together the oil, sugar, milk, vinegar, and vanilla extract until the sugar dissolves and the mixture becomes light and slightly fluffy.
In another bowl, sift together the all‑purpose flour, cocoa (or carob) powder, and baking soda so the dry ingredients are evenly blended and airy.
Slowly pour the wet mixture into the dry ingredients. Gently mix with a whisk or spatula from the center outward until just combined. Be careful not to overmix — stop as soon as the dry ingredients are incorporated. The batter should be runny in consistency.
Pour the batter into an 8‑inch baking tray that has been lined with parchment paper or greased and floured. Gently tap the tray on the counter a few times to release any large air bubbles in the batter before baking.
Bake in a preheated 350 °F (175 °C) oven for about 35–40 minutes, or until a skewer inserted in the center comes out clean. After baking, let the cake cool in the pan for about 15 minutes, then carefully invert it onto a cooling rack to cool completely.
Once cooled, you can frost the cake with chocolate frosting or simply slice it into thick pieces and serve.
