Ingredients:
- 1 cup (225g) unsalted butter, softened
- 1 cup (200g) granulated sugar
- 1 large egg (50g)
- 1 tsp (5ml) vanilla extract
- 3 cups (375g) all-purpose flour
- ¼ tsp (1.5g) salt
- ½ tsp (2.5g) baking powder
- 4 cups (480g) powdered sugar, sifted
- 3 tbsp (45ml) meringue powder
- 7 tbsp (105ml) warm water
- Gel food coloring
Instructions:
- Beat the butter and sugar until smooth. Add the egg and vanilla, mixing until fully incorporated.
- Sift flour, salt, and baking powder together. Gradually add to the wet ingredients until a stiff dough forms.
- Wrap the dough in plastic and refrigerate for 2 hours.
- Roll dough to ¼ inch thickness. Cut shapes and place on parchment-lined sheets. Bake at 350°F (175°C) for 10-12 minutes until the edges are just barely golden. Let cool completely on the pan.
- Whisk powdered sugar, meringue powder, and water. Divide into bowls and add gel colors.
- Using the stiff icing, pipe the border of the graduation cap or diploma.
- Switch to the flood icing and fill the center. Use a scribe tool to pop any air bubbles.
- Let the cookies sit undisturbed at room temperature for 24 hours to harden.
