Ingredients
Method
- Preheat oven to 180°C / 160°C fan / Gas 4. Grease and line two 20cm tins. Melt chocolate — cool 10 minutes.
- Beat butter and sugar 4–5 minutes. Add eggs one at a time. Add vanilla and cooled chocolate — beat to combine. Sift in flour, cocoa, and baking powder. Add ground almonds and milk — fold gently until just combined.
- Divide between tins — weigh for even layers. Bake 22–26 minutes until risen and skewer shows moist crumbs. Cool in tins 10 minutes. Cool completely on wire rack.
- Heat cream and golden syrup to just simmering. Pour over chopped chocolate — leave 2 minutes. Stir from centre until smooth. Add butter — stir until combined. Cool 45 minutes — 1 hour until thick and spreadable.
- Place one sponge on plate. Spread half the ganache. Top with second sponge — press gently. Spread remaining ganache over top and sides. Scatter chocolate curls. Dust with cocoa. Leave to set 30 minutes. Slice.
Notes
Check gluten free flour contains xanthan gum — it replaces the binding function of gluten.
Check every ingredient is certified gluten free — cocoa powder and baking powder can contain traces.
Ground almonds are not a compromise — they actively improve the texture.
Cool melted chocolate 10 minutes before adding to butter mixture — prevents splitting.
Do not overwork the gluten free batter — fold until just combined and stop.
Allow ganache to reach spreading consistency — 45 minutes to 1 hour at room temperature.
Freeze unfilled sponge layers for up to 3 months. Make ganache fresh.
