Heat the butter slightly and let it melt. After cooling, stir the butter, sugar and eggs until frothy. Add the ground almonds and finally sift the flour and baking powder over them. Knead everything into a dough and chill for about 1 hour.
Roll out the dough thinly on a surface sprinkled with flour and cut out different shapes.
Bake at 180 ° for about 10 minutes.
Let the cookies cool, cover with the couverture and decorate with the sprinkles.
P.S. Personally, I roll out the cookie dough very thinly and accordingly need more chocolate couverture. But 4 bags should be enough.
You can of course use ground hazelnuts instead of almonds.
