Chocolate Drip Cake with Xylitol and Erythritol

This chocolate layer cake uses almond meal, milled flaxseed, cocoa, xylitol and erythritol. It has a denser crumb than a conventional wheat-flour sponge and should be described accurately as a cake made without added caster sugar, not as universally sugar-free or automatically suitable for a particular diet. Dark chocolate, cocoa, baking powder and flavourings may contain sugar or other ingredients, so labels matter.

Chocolate Sponge Layers

Yield: three 6-inch layers. Ovens, tins and ingredient brands vary, so treat the baking time as a guide and check the centre carefully.

Ingredients

• 95g finely ground almond meal
• 60g finely milled golden flaxseed
• 8g baking powder, checked for dietary suitability where relevant
• 80g cocoa powder
• 5g instant coffee granules
• A pinch of salt
• 4 medium or large eggs
• 200g xylitol
• 70g unsalted butter
• 70g ghee

Method

1. Preheat the oven to 160°C fan. Grease three 6-inch round cake tins and line the bases.
2. Mix the almond meal, flaxseed, baking powder, cocoa, coffee and salt evenly in a bowl.
3. Whisk the eggs and xylitol in a separate large bowl until evenly combined.
4. Melt the butter and ghee gently, then leave them to cool until warm rather than hot. Whisk the fats slowly into the egg mixture so the eggs do not scramble.
5. Fold the dry ingredients into the wet mixture until no dry pockets remain. Do not continue mixing once the batter is even.
6. Divide between the tins and bake for about 15 minutes. Check the centre with a skewer; it may have a few moist crumbs but should not carry wet batter. Continue in short intervals when required.
7. Cool in the tins before turning the layers onto a wire rack.

Chocolate Swiss Meringue Buttercream

Use pasteurised egg whites and a digital thermometer. Feeling the bowl is not a reliable food-safety test.

Ingredients

• 150g pasteurised egg whites
• 70g erythritol
• 90g xylitol
• A pinch of salt
• 250g unsalted butter, softened but not greasy
• 5ml vanilla extract
• 70g cocoa powder, sifted

Method

1. Place the pasteurised egg whites, erythritol, xylitol and salt in a clean heatproof mixer bowl over gently simmering water. The bowl must not touch the water.
2. Whisk continuously and heat the mixture to 71°C, checking with a digital thermometer. Make sure the sweeteners are dissolved as far as their texture allows.
3. Transfer the bowl to the stand mixer and whisk at high speed until the meringue is glossy, holds firm peaks and the bowl has cooled.
4. Add the butter gradually at medium speed, followed by the vanilla. Continue mixing until smooth.
5. Add the sifted cocoa at low speed, then mix only until evenly combined.

Sugar alcohols behave differently from caster sugar and can recrystallise or feel cool on the palate. Results will vary by brand, so this should not be presented as a direct substitute for our standard Swiss meringue buttercream.

Chocolate Drip

Ingredients

• 50g dark chocolate, with the label checked for sugar and allergens
• 50g unsalted butter

Method

1. Melt the chocolate and butter gently in short microwave bursts or over a bain-marie.
2. Stir until smooth, then allow the mixture to cool. Test one drip on the chilled cake before covering the top; a hot glaze can melt the buttercream.

Assembling The Cake

1. Secure the first sponge to a cake board with a small amount of buttercream.
2. Fill and stack the three layers, keeping them level.
3. Apply a thin crumb coat and refrigerate until firm.
4. Add the final buttercream coat and return the cake to the refrigerator briefly.
5. Test the chocolate glaze, then add controlled drips around the edge and cover the top.
6. Finish with piped buttercream and hazelnuts only when nuts are safe for every person being served.

Storage And Serving

Keep the finished cake covered in the refrigerator because it contains buttercream made with egg whites and butter. Bring it towards cool room temperature before serving, keep it away from heat and sunlight, and return leftovers to the refrigerator promptly.
