Lemon Chocolate Marble Cake – Gluten-free version

👨‍🍳 Method

To assemble

1. 1
   Preheat the oven to 175°C (345°F) and grease cake pan 26 cm.

   ⚙ Preheating the OvenOven

   💡Put things in the oven only once it's reached temperature, after the heating light has gone off: an oven that hasn't reached temperature changes baking times, and the bake burns outside or stays underbaked.
2. 2
   Grate the zest and squeeze the juice.

   Whip the eggs and sugar 3–4 minutes, until the mixture is pale and fluffy.

   💡Room-temperature eggs whip better than cold eggs. Take them out of the fridge 30 minutes before baking. Warm eggs also make a more stable foam that holds up in the oven.
4. 4
   Add the oil, yogurt and vanilla extract, the zest and juice, and mix.
5. 5
   Sift the gluten-free flour blend and baking powder, combine, add to the wet mixture and Fold gently, just until no dry gluten-free flour blend remains.

   💡Fold in the gluten-free flour blend only until there are no pockets of dry gluten-free flour blend: overmixing develops gluten, and the cake comes out dense.

   💡Fold with a spatula, in broad strokes from the bottom up, and stop when there's no dry flour: vigorous mixing of a batter with flour develops gluten.

   Pour three-quarters of the batter into cake pan.

   Mix the cocoa and milk into the rest of the batter, pour on top and swirl with a spoon so the dark batter sinks into the light one in a marbled pattern.

   💡Check by the cue (until…), not just the clock: every oven bakes a little differently.
