Preheat your oven to 325”F.
In a large mixing bowl cream together the butter and 3/4 cup of the powder sugar until fluffy.
1 1/2 cup salted butter, 3/4 cup powder sugar
Add the vanilla extract and little by little the ground walnuts and hazelnuts. Mix until combined.
4 tsp vanilla extract, 3/4 cup ground walnuts, 3/4 cup ground hazelnuts
Start adding in the flour little by little until mixed in. ( For easier handling freeze or refrigerate the dough for 10 minutes or so)
3 cup all purpose flour
Prepare your largest cookie sheet and using a small spoon (or small ice-cream scoop) form the cookies into balls, the size of a golfball or smaller. You should have about 45 cookies.
Arrange all the cookies on the baking sheet without touching each other.
Bake the cookies in the preheated 325”F oven for 20 minutes.
Remove the wedding cookies from the oven and allow them to cool off for a few minutes before rolling them over in the reserved powder sugar. It's best that they are still a little bit warm so the sugar coating sticks nicely.
1/2 cup powder sugar for dusting
Arrange the cookies on a platter and dust with more powder sugar on top before serving.
