- Why did the middle sink?
- You likely opened the oven door too early before the structure set, or overmixed it with the flour.
- Can I replace the rum?
- Yes, use rum flavouring or orange juice if you want it alcohol-free.
Snowy chestnut cake
Chestnuts became a favourite in aristocratic kitchens in the 16th century. This cake is a modern reimagining of the classic 'Mont Blanc' dessert. The essence is the play of textures: the dense, rich chestnut sponge meeting the airy, light, cold whipped cream, crowned by crisp chocolate.

Instructions
1
✓
Preheat oven to 180°C (standard top-bottom heat). Line the bottom of the tin with baking parchment and grease the sides with butter.
Tip: Precise temperature is essential for the baking powder to start working and lift the dough. (Gas production)
2
✓
Cream the soft butter with the sugar until pale and fluffy (approx 5 mins with machine).
Tip: Creaming butter actually means trapping air bubbles in the fat, making the cake light. (Physical aeration)
3
✓
Add the eggs one by one, mixing thoroughly after each.
Tip: If added all at once, the fat and egg water content will separate (curdle). Adding one by one helps form a stable cream. (Emulsion)
4
✓
Mix in the mashed chestnut, rum, and vanilla. Finally, fold in the flour mixed with baking powder alternating with the milk.
Tip: Mix the flour gently, just until combined. Overmixing makes the dough rubbery and tough. (Gluten formation)
5
✓
Smooth batter into the tin and bake for 35-40 minutes. Test with a skewer: if it comes out clean, it's ready.
Tip: During baking, proteins set and starch absorbs water, forming the final structure of the cake. (Gelatinisation)
6
✓
Let the cake cool completely. Whip the cream with icing sugar until stiff peaks form, and spread over the top of the cake.
Tip: Only cold cream can be whipped, as the fat needs to be solid to hold air bubbles.
7
✓
Melt the chocolate and drizzle over the cream for decoration.
Tip: Careful, the chocolate shouldn't be piping hot or it will melt the whipped cream!
