👩🍳🇫🇷 Eléa joined A Grandchild in My Kitchen, Grandma Sita’s cooking challenge, to bake her family’s recipe for marble cake together.

It’s a simple family-style cake that children and grown-ups can enjoy making, slicing and sharing.
🍫✨ The best part is the surprise inside. As you cut into the cake, the chocolate and vanilla swirls reveal themselves, making every slice a little different. That playful marble effect is part of the charm of this classic-style cake, which is often enjoyed as a snack, for afternoon tea or alongside a coffee.
🌱 And because this is a Grandma Sita recipe, there’s always room to adapt. Use the chocolate you already have, add nuts if they need using or make the recipe your own with whatever suitable leftovers are waiting in your kitchen. Small changes can help us waste less while making homemade baking even more rewarding.
💚 So, let’s turn those everyday ingredients into something delicious! Bake this easy vegan chocolate marble cake, share a few slices with family and friends, and enjoy a little taste of French-inspired home baking — the Grandma Sita way!
INGREDIENTS
Dry ingredients
150 g cane sugar
250 g plain flour
11 g baking powder
½ tsp vanilla powder
1 tbsp cocoa powder
A pinch of salt
Wet ingredients
350 g vanilla soya drink
120 g olive oil
1 tbsp apple cider vinegar
1 tbsp rum (optional)
METHOD
1. Preheat the oven. Preheat the oven to 170°C, without the fan. Grease and line a loaf tin with baking parchment.
2. Combine the wet ingredients. Pour the vanilla soya drink and apple cider vinegar into a large bowl. Add the cane sugar and whisk until well combined.
3. Add the dry ingredients. Sift the plain flour and baking powder into the bowl. Add the vanilla powder and a pinch of salt, then gently mix with a whisk until just combined. Be careful not to overmix the batter.
4. Add the oil. Pour in the olive oil and gently fold it into the batter until fully incorporated.
5. Create the two batters. Divide the batter evenly between two bowls. Leave one half as the vanilla batter. Add the cocoa powder to the other half and, if using, stir in the rum. Mix gently until combined.
6. Create the marble effect. Pour alternate spoonfuls of the vanilla and chocolate batters into the prepared loaf tin. Gently run a knife through the batter to create beautiful chocolate and vanilla swirls.
7. Bake the cake. Bake for 10 minutes. Then, carefully make a shallow cut lengthways along the centre of the cake. Return it to the oven and bake for a further 30–35 minutes, or until golden and a skewer inserted into the centre comes out clean.
8. Cool and enjoy! Remove the cake from the oven and leave it to cool in the tin for a few minutes before transferring it to a wire rack. Slice and enjoy this delicious vegan chocolate marble cake with a cup of tea, coffee or as a simple homemade treat. Et voilà!
🧓🏻🤎 Grandma Sita’s Tips
- 🍫 Store chocolate well: Keep chocolate in a cool, dry and dark place, such as a cupboard or pantry, away from direct sunlight and strong smells. An airtight container can help keep it in good condition.
- ❄️ Too warm? If your kitchen is very hot and your chocolate is at risk of melting, you can refrigerate it in an airtight container. Let it return to room temperature before using it.
- ♻️ Use what you already have: Leftover chocolate, a handful of nuts or an almost-empty jar of jam can all find a delicious second life in your baking. Check your cupboards before heading to the shops!
- 🌀 Create beautiful swirls: Alternate the vanilla and chocolate batters, then gently swirl them together with a knife. Don’t overmix — a few simple movements are enough.
- 🍰 Let it cool: Allow the cake to cool before slicing. This helps the crumb set and makes it easier to get neat, beautiful slices.
📗 Did you know?
“Gâteau marbré” means “marbled cake” in French. The name comes from the beautiful patterns created by combining vanilla and chocolate batters. Depending on how the batter is swirled, every slice can have its own unique design.
🦓 It can also look like a zebra cake! When the contrasting batters create stripes, the pattern resembles a zebra — a fun variation on the classic marble effect.
