INGREDIENTS

Dry ingredients

• 1 cup (128 grams) all-purpose white flour
• 1 teaspoon baking powder
• Pinch of salt
• 1/2 cup + 2 tablespoons (125 grams) granulated sugar

Wet ingredients

• 15 tablespoons aquafaba (the liquid from canned chickpeas)
• 1 teaspoon alcohol-free vanilla flavoring
• 1 stick (113 grams) vegan butter, melted

Chocolate layers

• 4.4 oz (125 grams) vegan dark chocolate (make sure it’s dairy-free)
• 4.4 oz (125 grams) vegan white chocolate (if you can’t find it, you can skip it)

For the cake pan

• A bit of vegan butter (just enough to grease the pan)
• Parchment paper

STEP BY STEP INSTRUCTIONS

STEP 1) I start by grabbing my egg beater and whipping the aquafaba with the sugar until it looks super fluffy and almost doubles in size. It’s kinda wild how it gets thick and shiny, and when I drizzle some off the spoon, it folds over itself like a pretty little ribbon. That’s how I know I’ve nailed it.

STEP 2) I toss in the alcohol-free vanilla flavoring, the baking powder, and a small pinch of salt. I give it a quick mix to pull everything together. This step is fast but super important to get the flavors blended.

STEP 3) While that’s working, I melt my vegan butter. Sometimes I microwave it because, honestly, I’m not in the mood to wash extra pans. I pour the melted butter into the fluffy aquafaba mix while stirring, making sure it’s all mixed smoothly. I’m not rushing here. I stir gently to keep that lovely airiness.

STEP 4) I sift the flour right over the wet mix. No lumps allowed. I carefully fold everything together with my spatula like I’m wrapping a soft blanket. No smashing, just sweet little folds to keep it light and fluffy.

STEP 5) I split the batter into two bowls. In one, I stir in the melted vegan dark chocolate. In the other, I mix in the melted vegan white chocolate. Sometimes I get playful and swap flavors like strawberry or green tea. You know what? It’s your cake, go wild with it.

STEP 6) I preheat the oven to 360°F (180°C). I grease my cake pan with a little vegan butter and line it with parchment paper. I always press the paper down so it sticks properly and cut it nice and neat to fit the pan. Trust me, this saves you from a sticking disaster later.

STEP 7) I pour half of the white chocolate batter into the pan and spread it out. Then I layer all the dark chocolate batter on top and spread it gently. Finally, I pour the rest of the white chocolate batter over it. It doesn’t need to look perfect. It’s all gonna swirl anyway.

STEP 8) Now for the fun part. I grab a butter knife and swirl it through the batter like I’m doodling in a notebook. Big loops, little circles, I just have fun with it. There’s no right way to do this. Just swirl until you love the look.

STEP 9) I slide the cake into the oven and bake it for about 45 minutes. I don’t open the oven door too early. I learned that the hard way. When it turns golden on top and feels firm when I press it gently, I know it’s ready.

STEP 10) I let the cake cool down in the pan a bit before taking it out. I know waiting is hard because the smell is incredible, but patience is key here. Once it’s cool, I slice into the soft, fluffy layers, and seriously, it’s everything I wanted in a marble cake.

EXPERT COOKING TIPS

• Whip the aquafaba really well – don’t rush this part. The longer you whip, the fluffier your cake will be. I used to stop too early, and my cake turned out kinda flat. You want those shiny ribbons.
• Fold gently – when you add the flour, don’t smash it in. I used to stir like I was in a race, but nope, that kills the fluff. Just fold like you’re wrapping a gift.
• Use good-quality chocolate – I learned the hard way that cheap chocolate doesn’t melt well and can make the batter lumpy. Go for the smooth, dairy-free stuff.
• Don’t over-swirl – I used to think more swirls meant prettier cake, but too much mixing blends the layers together and ruins the marble effect. Just a few gentle swirls do the trick.
• Let it cool properly – I know it’s tempting to cut into it right away, but if you let it cool, the texture holds better, and the flavors come through. I’ve rushed this before and ended up with a crumbly mess.

RECIPE FAQ

VEGAN & ALLERGY-FRIENDLY SWAPS

• Aquafaba swap – you can use 1 and 1/4 cups of unsweetened applesauce if you don’t have aquafaba on hand. It won’t whip the same, but the cake will still come out soft.
• Vegan butter swap – if you’re out of vegan butter, a neutral oil like sunflower oil or light olive oil works just fine. I’ve tried both, and they keep the cake moist.
• White chocolate swap – if you can’t find vegan white chocolate, just skip it or replace it with another flavor like strawberry puree or matcha powder.
• Gluten-free option – you can use a gluten-free all-purpose flour blend. I’ve tested this with a good 1:1 gluten-free mix, and it holds up pretty well.
• Sugar swap – if you need to avoid refined sugar, coconut sugar or another granulated sweetener can work. Just keep in mind the color of the cake will be a little darker.

This Moist Marble Cake Recipe has become one of my go-to desserts when I want something soft, fluffy, and just plain fun to make. I love how simple the steps are and how the cake always comes out looking like a little work of art. The mix of rich chocolate and light vanilla flavors makes every bite feel special. Honestly, it’s one of those recipes I keep coming back to because it never disappoints. I hope you enjoy baking it as much as I do!
