Festive spiced latte cake

Preheat the oven to 180ºC, gas mark 4. Use a little of the butter to grease a 23cm springform tin, then line the base. Sift the flour and baking powder into a large bowl. Add the light brown soft sugar, a pinch of nutmeg and the salt. Mix well with your hands to smooth any lumps in the sugar, then make a well in the middle.

In a cup, mix 1 tbsp coffee with 1 tbsp hot water. Stir into the melted butter with the milk, 175g custard and the eggs; whisk into the dry ingredients until smooth. Pour into the tin and bake for 50 minutes, until risen, golden and a skewer inserted into the centre comes out clean. While the cake bakes, mix 1 tsp coffee with 2 tbsp caster sugar, 1 tbsp water and 1 tbsp rum to make a syrup; set aside.

Place the cake, in its tin, on a wire rack to cool. After 30 minutes, poke lots of holes into the top using a cocktail stick and brush with the coffee syrup. Once cooled completely, remove from the tin and put on a plate.

Make a frothy topping by whipping the cream with the remaining 2 tbsp caster sugar and 1 tbsp rum until very thick, then fold into the remaining 100g custard. Spoon and spread the topping onto the cake, then use a fine sieve or tea strainer to dust with the remaining ½ tsp nutmeg.
