Whisk egg and sugar until puffy and white.

Mix flour with all the spices and the baking powder.

Melt the butter and add the cream/milk. Mix this with the eggs and the flour. Stir well.

Pour the batter in a buttered and breaded spring form and bake for 35-45 minutes in 175°C. (The baking time varies so check after 35 minutes.)

Let cool for 10 minutes before you turn it up side down on a plate. Powder with icing sugar just before serving.
