Ingredients:
- 1 cup (225g) unsalted butter, chilled and cubed
- 3/4 cup (150g) granulated sugar
- 1 large (50g) egg, room temperature
- 2 tsp (10ml) pure vanilla extract
- 3 cups (375g) all-purpose flour
- 2 tbsp (16g) cornstarch
- 1 tsp (5g) baking powder
- 1/4 tsp (1.5g) salt
- 4 cups (480g) powdered sugar, sifted
- 3 tbsp (25g) meringue powder
- 6 tbsp (90ml) warm water
- Gel food coloring (Pastel pink, yellow, and leaf green)
Instructions:
- Cream the chilled butter and sugar together until combined but not fluffy to avoid adding too much air.
- Mix in the room temperature egg and vanilla extract.
- Gradually fold in the all-purpose flour, cornstarch, baking powder, and salt until a stiff dough forms.
- Wrap the dough in plastic and refrigerate for at least 2 hours to prevent spreading during baking.
- Preheat oven to 350°F (175°C) and line a baking sheet with parchment paper.
- Roll the chilled dough to a consistent 1/4 inch (6mm) thickness and cut out floral shapes.
- Bake for 8–10 minutes until edges are just barely set and pale. Let cool completely on the pan.
- Prepare royal icing by mixing powdered sugar, meringue powder, and warm water until glossy and stiff.
- Divide the icing into bowls and add gel food coloring.
- Using a petal piping tip, pipe outward from the center of the cookie to create layered petals.
