Irish Coffee Ice Cream Cake
Serves 10
cake:
250 g almond paste
2 egg whites
2 tbsp cocoa powder
ice cream:
400 ml heavy/double cream (35-40% fat)
2 tbsp instant coffee
100 ml (0.4 cups) powdered sugar
2 egg yolks
2 tbsp whiskey
Grate the almond paste and mix with cocoa and egg whites until smooth. Spread into a greased springform pan (line the bottom first with parchment paper if you're at all nervous about getting the cake out) and bake at 175°C for 12-15 minutes. Remove the cake from the tin and let it cool completely on a rack. Wash the pan.
When the cake is cooled, put it back in the now-clean pan. Beat the cream with powdered sugar and instant coffee until it's really thick. Stir in egg yolks and whiskey. Pour this on top of the cake, cover with plastic foil and freeze over night or for at least four hours.
Serve with a little bit of cocoa powder on top, or with chocolate covered coffee beans.
