Ingredients:
- 1 cup (225g) unsalted butter, softened
- 1 cup (200g) granulated sugar
- 1 large (50g) egg
- 1 tsp (5ml) vanilla extract
- 3 cups (375g) all-purpose flour
- 2 tsp (10g) baking powder
- 1/2 tsp (3g) salt
- 4 cups (480g) powdered sugar, sifted
- 3 tbsp (45ml) meringue powder
- 5 tbsp (75ml) warm water
- 2 oz (56g) yellow fondant
- cornstarch
Instructions:
- Cream the butter and sugar until pale and fluffy. Beat in the egg and vanilla until fully incorporated.
- Slowly mix in the flour, baking powder, and salt on low speed until a stiff dough forms.
- Divide dough into two discs, wrap in plastic, and refrigerate for at least 2 hours.
- Preheat oven to 350°F (175°C) and line baking sheets with parchment paper.
- Roll dough to 1/4 inch (6mm) thickness on a lightly floured surface and cut into graduation cap shapes.
- Bake for 10-12 minutes until edges are barely set. Cool on the pan for 5 minutes before transferring to a wire rack.
- Pipe a border around the diamond top and base of the cap using stiff black royal icing.
- Fill in the centers with flood consistency icing and pop air bubbles with a scribe tool.
- Roll a thin rope of yellow fondant and attach it to the center of the cap to create the tassel.
- Allow cookies to dry undisturbed for 8-12 hours until the icing is completely hard.
