Mix the butter with the sugar and the vanilla to a fluffy mass. Add the egg yolks one by one, then add the almonds. Continue by adding the flour and end by folding in the beaten egg whites.

Butter a pastry tin, dust it with flour, pour in the mixture and bake the pie in the middle of a preheated oven (175° C – 355° F) until it is golden.

Yields 1 pie.
