Step 1: Ingredients
1 Tbsp. sugar
1 1/2 cups all-purpose flour
1/2 cup confectioner's sugar (powdered sugar)
1/4 cup cornstarch
3/4 cup cold butter, cubed
2 Tbsp. Nutella
1 egg, lightly beaten (not pictured)
Step 2: Cubed Butter
Step 3: Preheat the Oven and Prepare the Topping
In a small bowl, mix the hazelnuts and sugar.
Step 4: Making the Dough
Cut in the butter until crumbly. Since I already cut my butter into cubes, I just added the butter a few cubes at a time and mixed them in.
Step 5: Kneading the Dough
Knead gently until the mixture forms a soft dough. This basically means just squeeze it and squish it until it looks more like dough and less like a pile of flour. The original recipe says about 2 minutes, but it took me more like 10.
I know this looks like magic, but if you just keep kneading it will eventually look like dough!
Divide your dough in half.
Step 6: Rolling and Cutting
Cut with a floured cookie cutter, between 2 and 3 inches.
Transfer cookies to a greased baking sheet.
Step 7: Fill, Fold, Sprinkle
Fold your cookies partway over, just enough to cover the filling. The cookies will probably break at the fold, but that's okay.
Brush the tops of the cookies with the beaten egg, then sprinkle with hazelnut mixture.
Step 8: Bake!
Enjoy your delicious cookies!
