Graduation Diploma Cap Cookies (Printable Version)

Buttery diploma and cap sugar cookies iced in white, black and gold for a polished graduation display.

# What You'll Need:

→ Sugar cookies

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

→ Royal icing

08 - 3 cups powdered sugar, sifted
09 - 2 large egg whites (or 4 tablespoons meringue powder + 6 tablespoons water)
10 - 1/2 teaspoon cream of tartar
11 - 1 teaspoon vanilla extract
12 - Black gel food coloring, as needed
13 - Gold edible luster dust and a few drops of clear alcohol or lemon extract for painting

# Method:

01 - In a large bowl, use an electric mixer to cream 1 cup unsalted butter and 3/4 cup granulated sugar until light and fluffy. Beat in 1 large egg, 1 teaspoon vanilla extract and 1/2 teaspoon almond extract if using, mixing until combined.
02 - Gradually add 2 1/2 cups all-purpose flour and 1/2 teaspoon salt to the butter mixture on low speed, mixing just until the dough comes together and no large streaks of flour remain.
03 - Divide the dough in half, flatten each portion into a disc, wrap in plastic and chill in the refrigerator for 45 minutes to firm up for rolling.
04 - Preheat the oven to 350°F. Line baking sheets with parchment paper and set aside.
05 - On a lightly floured surface, roll one disc of dough to a 1/4-inch thickness. Cut out diploma and graduation cap shapes with cutters, transferring cookies to prepared sheets with minimal handling.
06 - Bake cookies, one sheet at a time, for 8–10 minutes or until the edges are just golden. Remove from the oven and cool completely on wire racks before decorating.
07 - In a clean bowl, beat 2 large egg whites until frothy. Gradually add 3 cups sifted powdered sugar and 1/2 teaspoon cream of tartar, then beat until the icing holds stiff, glossy peaks. Stir in 1 teaspoon vanilla extract.
08 - Divide the icing into portions: tint one portion with black gel coloring for caps, leave a portion white for diplomas and reserve a small amount plain to mix with gold luster dust for accents.
09 - Using piping bags and fine tips, pipe outlines, flood the shapes and add details. Allow the flooded icing to set for about 1 hour before adding painted accents.
10 - Mix gold luster dust with a few drops of clear alcohol or lemon extract to create a paint. With a food-safe fine brush, apply gold to tassels and diploma ribbons. Let all decorations dry completely before storing or serving.

# Expert Tips:

01 -
  • The gold-tipped royal icing transforms every cookie into a show-stopping centerpiece that looks as good as it tastes.
  • Each step, from mixing to decorating, is surprisingly soothing—offering a calm, focused break before the festivities begin.
02 -
  • Chilling the dough fully is essential—after too many sticky disasters, I never skip this step.
  • Let each layer of icing set before adding gold; hurrying leads to smuged details and less dramatic cookies.
03 -
  • If the dough seems soft when rolling, dust both your pin and surface with flour—it’s the difference between frustration and fun shapes.
  • For super-sharp designs, chill shaped cookies on the tray before baking.
