Ingredients

200 g all-purpose flour
150 g sugar
3 large eggs
100 g unsalted butter, melted
100 ml milk
1 teaspoon vanilla extract
2 tablespoons cocoa powder
1 teaspoon baking powder
Pinch of salt

Instructions

Step 1: Prepare the Thermomix

Grease a heatproof steaming tin that fits inside your Varoma tray. Set aside.

Step 2: Mix the Batter

Place eggs and sugar in the Thermomix bowl. Beat for 2 minutes / 37°C / speed 4, until light and frothy.
Add melted butter, milk, and vanilla. Mix 10 seconds / speed 3.
Add flour, baking powder, and salt. Mix 20 seconds / speed 4 until a smooth batter forms.

Step 3: Create the Marble Effect

Transfer half of the batter into another bowl.
Add cocoa powder to one half and fold gently with a spatula until combined.

Step 4: Layer the Batter

Alternate spoonfuls of vanilla and chocolate batter into the prepared steaming tin. Use a skewer or knife to swirl lightly for a marbled effect.

Step 5: Steam the Cake

Fill the Thermomix bowl with 500 ml water.
Place the Varoma tray with the cake tin on top. Cover with the Varoma lid.
Steam for 35–40 minutes / Varoma temperature / speed 2. Check doneness with a skewer—it should come out clean.

Step 6: Cool and Serve

Remove the cake from the Varoma and allow it to cool slightly before slicing. Serve warm or at room temperature. Optionally, dust with powdered sugar or drizzle with chocolate.

Tips for Best Results

Ensure your steaming tin fits inside the Varoma without touching the lid.
Do not lift the Varoma during steaming, as this can cause the cake to sink.
Fold the chocolate batter gently to maintain a light, fluffy texture.
For extra flavor, add a teaspoon of instant coffee to the chocolate portion.

Storage

Keep in an airtight container at room temperature for 2–3 days
Can be refrigerated for up to 5 days
Reheat slices lightly in a steamer or microwave before serving

Variations

Orange-Chocolate Marble: Add orange zest to the vanilla batter
Coffee-Chocolate Marble: Add a teaspoon of instant coffee to the chocolate batter
Nutty Marble: Sprinkle chopped nuts on top before steaming
