Dark and stormy cake with rum and lime buttercream recipe

September 2024 · 3 minute read

The only ginger-flavoured food I don’t like is the very dark ginger cake, made with molasses or treacle. I was determined to find a ginger cake I really liked, and this is it. It’s moist and gorgeous.

Method

1. Heat the oven to 180C/170C fan/gas mark 4. Butter two 20cm cake tins and line the bases, buttering the paper as well.

2. Because soft brown sugar tends to clump together, put it in a bowl and break the lumps down with a fork or the back of a spoon. Add the golden caster sugar and blend them well.

3. Sift the flour, baking powder, cornflour and ground ginger together in a separate bowl. Add a pinch of salt.

4. Cream the butter and sugar together until light and fluffy. Beat in the eggs a little at a time, but after the first addition add a tablespoon of the flour mix – this stops the eggs and butter curdling. Add the lime zest and vanilla.

5. Fold in the flour mixture in three more goes, using a large metal spoon. Alternate with the milk, ending with the last portion of flour. Mix in the rum. 

6. Divide the batter between the two tins and smooth the tops. Bake for 30 minutes, or until you can see the cakes coming away from the sides of the tins.

7. Remove from the oven and leave the cakes in their tins for 15 minutes, then turn out on to a wire cooling rack and carefully remove the paper.

8. Simmer all the syrup ingredients except the lime for two minutes, stirring to help the sugar melt. Add the lime.

9. Place each sponge on a plate, bottom-side up. Prick them all over with a skewer and brush them with the syrup, being generous with it.

10. Cover the sponges with foil and leave for an hour, then spoon on more of the syrup. Repeat – you can leave the cakes covered with foil overnight.

11. To make the buttercream, beat the butter and gradually add the icing sugar. Add the lime zest and juice and mix again, then slowly add the rum. Spoon or pipe half the buttercream on to the sponge you’re using as the bottom layer, then put the other sponge on top. Spread or pipe the rest of the buttercream on top of that. 

12. Decorate with preserved ginger and, if you like, some finely sliced lime.
