Using a hand whisk, beat together the butter, sugar, and vanilla until creamy. Add the egg yolk and beat well. Stir in the flour and ground almonds (if using) and quickly mix to a firm dough using your hands. Knead into a ball, wrap in plastic wrap, and refrigerate for 2 hours.

| 1 1/4 sticks butter, room temperature | 1 1/2 cups all-purpose flour, plus extra for dusting | |
| 3/4 cup confectioners' sugar | 1/3 cup ground almonds (optional) | |
| 1 drop pure vanilla extract | 15 colored hard candies | |
| 1 egg yolk |
Divide the candies by color, place each color in a plastic bag, and seal. Using a rolling pin, smash the candies into tiny pieces.
Preheat the oven to 350 degrees F.
On a lightly floured surface, roll out the dough to a thickness of 1/4 inch. With cookie cutters, cut into 2 3/4-inch shapes. Cut out patterns in the center of each cookie, leaving a generous margin. Put on the baking sheets and fill each hole with one color of crushed candy.
Bake for 8 minutes, or until golden brown. Remove from the oven and leave for 1 minute, then remove with a spatula onto a cooling rack.
Grease 2 nonstick baking sheets before you begin.
