This Mary Berry Gluten-Free Chocolate Cake is a rich and fudgy recipe, which is naturally gluten-free thanks to the use of ground almonds instead of flour. It’s a classic, foolproof recipe that results in a dense, moist cake perfect for any special occasion.
Mary Berry Gluten-Free Chocolate Cake Ingredients
For the Cake:
- 265g (9½oz) plain chocolate (around 40% cocoa solids), broken into pieces
- 1 level tsp instant coffee granules
- 1 tsp hot water
- 6 large eggs (5 separated, 1 whole)
- 215g (7½oz) caster sugar
- 150g (5oz) ground almonds
For the Icing and Filling:
- 4 tbsp apricot jam
- 225g (8oz) plain chocolate, broken into pieces
- 100g (4oz) unsalted butter
How To Make Mary Berry’s Gluten-Free Chocolate Cake
- Prep the oven and tin: Preheat the oven to 190°C/170°C Fan/Gas 5. Grease a 23cm (9in) deep round cake tin and line the base with non-stick baking parchment.
- Melt the chocolate: Dissolve the coffee granules in the hot water. Place the 265g of plain chocolate in a heatproof bowl over a pan of simmering water (a bain-marie) and add the coffee mixture. Stir occasionally until the chocolate is melted and smooth, then set aside to cool slightly.
- Mix the base: In a large bowl, beat the 5 egg yolks and the 1 whole egg with the caster sugar until the mixture is thick, pale, and leaves a trail when the whisk is lifted. Stir in the ground almonds and the slightly cooled melted chocolate.
- Fold in egg whites: In a separate, clean bowl, whisk the 5 egg whites until they form stiff, but not dry, peaks. Gently fold one large spoonful of the egg whites into the chocolate mixture to loosen it up. Then, carefully fold in the remaining egg whites in two batches using a large metal spoon, being careful not to knock out the air.
- Bake the cake: Pour the batter into the prepared tin and gently level the surface. Bake for about 50 minutes, or until the cake is well-risen and a skewer inserted into the center comes out clean. Let it cool in the tin for 10 minutes before turning it out onto a wire rack to cool completely.
- Prepare for icing: Gently warm the apricot jam in a small pan until it’s runny. Brush the jam all over the top and sides of the cooled cake. This will seal the cake and prevent crumbs from getting in the icing.
- Make the icing and finish: Melt the 225g of plain chocolate and the butter together in a bowl over simmering water until smooth. Let it cool until it has the consistency of thick pouring cream. Place the cake on a wire rack over a tray to catch drips, then pour the icing over the cake, using a palette knife to smooth it over the top and sides. Let it set in a cool place.

Recipe Tips
- How to get a light, airy cake? The key is in the egg whites. Whisk them until they are stiff enough to hold their shape, but stop before they become dry and clumpy. When folding them into the chocolate mixture, use a gentle figure-of-eight motion with a metal spoon to keep as much air in the batter as possible.
- What is the purpose of the coffee? The instant coffee doesn’t make the cake taste like coffee; instead, it deepens and enhances the flavor of the chocolate, giving it a richer taste.
- Can I use a different nut? Ground almonds provide the best texture and moisture for this cake. You could experiment with finely ground hazelnuts for a different flavor profile.
- How to get a smooth icing? Let the melted chocolate and butter cool sufficiently before pouring it over the cake. If it’s too warm, it will be too thin and run straight off.
What To Serve With Gluten-Free Chocolate Cake
This rich, fudgy cake is a decadent treat on its own, but it’s also wonderful with:
- A dollop of fresh, unsweetened whipped cream or clotted cream
- A scoop of high-quality vanilla bean ice cream
- A side of fresh raspberries to cut through the richness
How To Store Gluten-Free Chocolate Cake
- Room Temperature: Store the cake in an airtight container in a cool place for up to 4-5 days. It is naturally moist and keeps very well.

FAQs
Yes, this is a fudgy, dense, and moist cake, more like a torte than a light sponge. It is naturally dense because it uses ground almonds instead of flour.
To make it dairy-free, you would need to use a good quality dairy-free plain chocolate and substitute the butter in the icing with a dairy-free baking block or spread.
This can happen if the cake is underbaked or if too much air was knocked out when folding in the egg whites. Make sure to bake it until a skewer comes out clean, and be very gentle during the folding stage.
