How to make
The butter and sugar are whipped into a thick and fluffy cream. Add the egg yolks, one at a time, by beating well after each one, until the yolk is absorbed well. The flour is sifted with the starch and baking powder. Add the salt and vanilla.
The flour mixture is gradually added to the butter mixture and a soft dough is formed into a ball. Wrap it in foil and leave it in the fridge for an hour to harden.
When ready, roll out the dough onto baking paper into a thickness of about 3 mm and use a cookie cutter of choice to cut out the cookies.
Bake them in a preheated oven at 340°F (170°C) for about 10 minutes. They should not turn brown, but even if they do, they will still be delicious.
After taking them out, leave them to cool in the tray. Stick them together with finished dulce de leche. The sweets are rolled in coconut flour.
The Alfajores Butter Cookies are ready.
