Gluten-Free Mary Berry Chocolate Cake Recipe: Classic & Indulgent

If you love classic British baking, you know that nothing beats an authentic Mary Berry chocolate cake recipe. Known for its rich flavor, moist crumb, and signature chocolate fudge icing, Mary Berry's legendary sponge cake is a staple in sweet lovers' kitchens around the world.

Here at Sweety's Bakery, we believe nobody should miss out on iconic desserts due to dietary restrictions. That is why we have adapted this famous treat into a scrumptious, 100% gluten-free version that tastes just as light and decadent as the original!

Why This Gluten-Free Adaptation Works

Traditional sponge cakes rely on wheat flour for structure. However, by substituting a high-quality 1:1 gluten-free baking blend alongside premium cocoa powder, you achieve a velvety texture without sacrificing any of that signature chocolate flavor.

Precision is essential when adapting classic recipes to gluten-free alternatives. Because gluten-free flours vary in density compared to standard all-purpose flour, measuring by weight yields the best results. Use our handy Cups to Grams Converter to ensure perfect measurements every single time!

Ingredients

For the Chocolate Cake:

• 225g (8 oz) gluten-free self-raising flour blend (containing xanthan gum)
• 50g (1.75 oz) unsweetened cocoa powder
• 2 tsp gluten-free baking powder
• 225g (8 oz) unsalted butter, softened
• 225g (8 oz) caster sugar
• 4 large eggs, at room temperature
• 2 tbsp milk

For the Chocolate Fudge Icing:

• 175g (6 oz) dark chocolate (70% cocoa solids, gluten-free certified)
• 150ml (5 fl oz) double cream
• 2 tbsp apricot jam (warmed and strained)

Step-by-Step Instructions

1. Prepare Your Kitchen

Preheat your oven to 180°C (160°C Fan / Gas 4). Line two 20cm (8-inch) round sandwich cake tins with parchment paper and lightly grease the sides.

2. Combine the Sponge Ingredients

Sift the gluten-free flour, cocoa powder, and baking powder into a large mixing bowl. Add the softened butter, caster sugar, eggs, and milk. Using an electric hand mixer, beat the mixture for roughly 2 minutes until it becomes smooth and glossy. Take care not to overmix, as keeping air in the batter helps gluten-free cakes stay fluffy.

3. Bake to Perfection

Divide the cake batter evenly between your prepared tins and smooth the tops with a spatula. Bake in the center of the preheated oven for 20 to 25 minutes. The cakes are done when they spring back gently to the touch and a skewer inserted into the center comes out clean.

4. Cool Completely

Allow the sponges to cool in their tins for 5 minutes. Gently run a butter knife around the inner edges and invert them onto a wire cooling rack to cool completely before frosting.

5. Prepare the Chocolate Fudge Icing

Break the dark chocolate into small pieces and place them in a heatproof bowl with the double cream. Place the bowl over a pot of gently simmering water, ensuring the bottom of the bowl does not touch the water. Stir occasionally until melted and silky smooth. Remove from heat and allow it to cool slightly until it thickens to a spreadable consistency.

6. Assemble the Cake

Spread the warmed apricot jam over the top of one sponge layer to seal in moisture. Layer half of the chocolate fudge icing over the jam, then gently place the second sponge on top. Cover the top and sides of the assembled cake with the remaining icing using an offset spatula.

Pro Tips for Gluten-Free Baking Success

• Check Ingredient Labels: Double-check that your baking powder, chocolate, and cocoa powder are certified gluten-free to avoid cross-contamination. You can review ingredient standards at the USDA FoodData Central.
• Maintain Moisture: Gluten-free flour blends absorb liquid quickly. If your batter seems overly thick, mix in one extra tablespoon of milk before baking.
• Storage: Keep your finished cake stored in an airtight container at room temperature for up to 3 days to preserve freshness.
