- Why did the middle sink?
- You opened the oven too soon or used too much baking powder. Thermal shock causes the batter structure to collapse before it sets.
Rum & coffee cake
This cake is the love child of tiramisu and a rich chocolate cake. Espresso adds depth to the cocoa (coffee enhances the chocolate flavour), whilst the rum relaxes the batter and adds aroma. It's not a dry sponge, but a moist, buttery batter that stays fresh for days.

Instructions
1
✓
Mix the dry ingredients (flour, sugar, cocoa, baking powder) in a bowl.
Tip: It's worth sifting the cocoa powder as it tends to form small lumps that taste bitter in the cake.
2
✓
Mix the melted butter, milk, coffee, rum and egg yolks. Pour into the dry mixture.
Tip: The acidity of the coffee reacts with the baking powder, helping the rise.
3
✓
Whisk the egg whites to stiff peaks. Gently fold into the cocoa mixture using a spatula.
Tip: The egg whites provide the air. Don't mix wildly, just 'fold' so the bubbles don't break.
4
✓
Bake at 180°C (conventional oven) for 35-40 minutes. A skewer test is mandatory!
Tip: If liquid batter no longer sticks to the skewer, only a few crumbs, take it out. If it comes out completely clean, it might be slightly overbaked.
5
✓
Let it cool, dust with icing sugar, and serve with whipped double cream.
Tip: The fat (cream) counterbalances the dryness of the cocoa.
