Cream the butter; gradually beat in the sugar. Mix in the flour and cinnamon. Add 1 egg yolk at a time, beating after each addition and until light and fluffy. Gradually add the coconut cream. Fold in the egg whites. Divide among 8 buttered custard cups. Set in a shallow pan of hot water. Bake 45 minutes or until set. Chill and turn out.
This dessert is much different from the typical coconut cookies or other desserts.
