Buttery sugar cookies cut as diplomas and caps, iced with glossy royal icing and gold accents for grad celebrations.

# What You'll Need:

→ Sugar Cookies

01 - 2 1/2 cups (315 g) all-purpose flour
02 - 1 cup (225 g) unsalted butter, room temperature
03 - 3/4 cup (150 g) granulated sugar
04 - 1 large egg
05 - 1 tsp pure vanilla extract
06 - 1/2 tsp almond extract (optional)
07 - 1/2 tsp salt

→ Royal Icing

08 - 3 cups (360 g) powdered sugar, sifted
09 - 2 large egg whites (or 4 tbsp meringue powder + 6 tbsp water)
10 - 1/2 tsp cream of tartar
11 - 1 tsp vanilla extract
12 - Black gel food coloring
13 - Gold edible luster dust + clear alcohol or lemon extract

# How to Make It:

01 - In a large bowl, cream together butter and sugar until light and fluffy. Beat in egg, vanilla extract, and almond extract (if using).
02 - Add flour and salt gradually. Mix until dough just comes together.
03 - Divide dough in half, flatten into discs, and wrap in plastic wrap. Chill for 45 minutes.
04 - Preheat oven to 350°F (175°C). Line baking sheets with parchment paper.
05 - Roll dough out on a floured surface to 1/4-inch thickness. Cut out diploma and graduation cap shapes with cookie cutters.
06 - Place cookies on prepared sheets. Bake for 8–10 minutes or until edges are just golden. Cool completely on wire racks.
07 - For royal icing: Beat egg whites in a clean bowl until frothy. Gradually add powdered sugar and cream of tartar, beating until stiff, glossy peaks form. Stir in vanilla.
08 - Divide icing: Tint a portion black for caps, leave some white for diplomas, and set some aside for gold.
09 - Decorate cooled cookies with icing: Pipe outlines, flood, and detail as desired. Let set 1 hour.
10 - Mix gold luster dust with a few drops of clear alcohol to form a paint. Using a fine brush, add gold accents to tassels and diploma ribbons. Allow icing and details to dry completely before serving.

# Expert Tips:

01 -
  • This recipe makes you look effortlessly impressive with a few simple tools and a bit of luster dust.
  • The cookies are as buttery and tender as the icing is crisp, making each bite a perfect blend of comfort and celebration.
02 -
  • Once, I rushed chilling the dough and my caps lost their form in the oven—they puffed up and became nearly unrecognizable.
  • Adding a few drops of lemon extract to the gold luster powder made the shimmer smoother and more intense, transforming the look.
03 -
  • Always sift powdered sugar before making royal icing—clumps can stick in fine piping tips and ruin your neat designs.
  • A steady hand helps, but don't worry if your lines aren't perfect—the touch of gold will steal the show every time.
