Ingredients You’ll Need

All the ingredients in this Vegan Marble Cake Recipe come together to create a balance of moistness, flavor, and lift. When you pick your vegan butter, I recommend block style for that perfect melt and creaminess in the batter. Also, using room temperature plant milk and yoghurt helps the batter come together smoothly without clumps.

• Vegan butter block style: The block melts beautifully, giving the batter richness and moisture.
• Cocoa powder: Use unsweetened for a deep chocolate flavor in your swirls.
• Boiling water: Helps bloom the cocoa powder to maximize its chocolatey intensity.
• Plain white flour: This all-purpose flour keeps the cake light and tender.
• Cornstarch: Adds a delicate crumb and softness to the cake texture.
• Baking powder & bicarbonate of soda: Work together to make the cake rise nicely.
• Fine sea salt: Enhances all the flavors in a subtle way.
• Caster sugar: Dissolves quickly, ensuring an evenly sweet cake.
• Vegan yoghurt (unflavored, unsweetened): Keeps the cake moist without any tangy overpowering.
• Plant milk (unflavored, unsweetened): I prefer soy or oat milk for creaminess, but any neutral variety works.
• Vanilla extract: Adds warmth and depth to the vanilla batter portion.
• White vinegar: Reacts with the baking soda to give a nice rise and tender crumb.

Variations

I love tweaking this Vegan Marble Cake Recipe depending on the occasion. It easily adapts to what you have on hand or the flavors you’re craving. Don’t be shy about making it your own!

• Nutty Twist: I once stirred in a handful of chopped toasted walnuts to the vanilla batter—added a lovely crunch that my family went crazy for.
• Spiced Swirl: Adding a pinch of cinnamon or a sprinkle of chili powder to the cocoa batter makes the marbled pattern even more interesting and flavorful.
• Fruit Boost: Swapping the white vinegar with apple cider vinegar and adding fresh or dried berries gives the cake a fruity zing and extra moistness.
• Gluten-Free: Try a gluten-free flour blend instead of all-purpose flour, just be mindful of the texture—it might be slightly denser but still delicious.

How to Make Vegan Marble Cake Recipe

Step 1: Prepare and Preheat

First things first: slice about 15g worth of vegan butter into thin rods and freeze them. This little trick will give you a fun surprise texture after baking. Meanwhile, preheat your oven to 160°C (320°F) and line a 2lb loaf tin with greaseproof paper—this lining makes it so easy to lift your cake out later without sticking or crumbling.

Step 2: Mix Dry Ingredients and Cocoa

Whisk your flour, cornstarch, baking powder, bicarbonate of soda, and salt together in a medium bowl—that’s your dry base. Then, in a small bowl, stir cocoa powder into boiling water until smooth and dark—that blooming step really intensifies the chocolate flavor.

Step 3: Blend Wet Ingredients

Using a high-speed blender or a whisk, combine caster sugar, vegan yoghurt, plant milk, vanilla extract, white vinegar, and melted vegan butter until super smooth. Gradually add this wet mixture to your dry ingredients—do it in small increments while whisking gently so you get a silky, lump-free batter without overmixing.

Step 4: Create the Marble Effect

Split the batter almost in half, then whisk the cocoa mixture into one half. In your loaf tin, alternate spooning vanilla and chocolate batter layers. I usually start with a vanilla layer to get a nice contrast at the base. Then, use a bamboo skewer to swirl the layers gently—don’t overdo it or you’ll lose the pretty marbled look!

Step 5: Add the Secret Butter Strip and Bake

Lay your frozen strip of vegan butter right down the center of the batter in the loaf tin. This melts during baking, giving a slightly gooey ribbon effect in the middle that I adore. Bake on a preheated baking sheet for about 60 minutes. You’ll know it’s done when a skewer inserted near the center comes out mostly clean with just a few moist crumbs.

Step 6: Cool and Enjoy

Let the cake cool in the tin for 15 minutes—this resting period lets it firm up so it won’t break when you remove it. Then, transfer it to a wire rack to cool completely before slicing. Trust me, the full-cool down makes slicing clean and keeps the texture perfect for those beautiful swirls to shine.

How to Serve Vegan Marble Cake Recipe

Garnishes

I love keeping it simple—a light dusting of powdered sugar or some toasted almond flakes scattered on top brings just enough extra flair. For celebrations, a drizzle of vegan chocolate ganache or a dollop of coconut whipped cream can turn it into a decadent treat.

Side Dishes

Pair your vegan marble cake slice with fresh berries or a warm cup of coffee or chai tea—this combo has become my go-to afternoon pick-me-up. It’s also fantastic alongside a fruit compote or some dairy-free vanilla ice cream for dessert.

Creative Ways to Present

For birthdays or brunch, I’ve served this cake sliced vertically to show off the marbled cross-section on each plate, adding edible flowers or fresh mint leaves for color. Another fun idea is to make mini loaf cakes in individual tins—perfect for gifting or portion control!

Make Ahead and Storage

Storing Leftovers

I wrap the cooled vegan marble cake tightly in plastic wrap and keep it in an airtight container at room temperature for up to three days. It stays moist and soft, I promise. If your kitchen is warm, storing it in the fridge works too, just bring it back to room temp before serving for best flavor.

Freezing

I’ve frozen slices wrapped individually in parchment and foil for up to a month. When it’s time to enjoy, thaw overnight in the fridge or for a few hours on the counter—it retains that lovely texture and flavor.

Reheating

To warm up slices, I pop them in a toaster oven or microwave for just 10-15 seconds. You’ll get that fresh-baked warmth and softness back, making every bite feel just like the first.
