Ingredients

Scale
  • 2 ½ cups (315 g) all-purpose flour, sifted
  • 1 teaspoon (4 g) baking powder
  • ½ teaspoon (3 g) salt
  • 1 cup (227 g) unsalted butter, softened
  • 1 cup (200 g) granulated sugar
  • 1 large egg, room temperature
  • 2 teaspoons (10 ml) pure vanilla extract
  • ½ cup (113 g) unsalted butter, softened (for filling)
  • 2 cups (240 g) powdered sugar, sifted
  • 1 teaspoon (5 ml) vanilla extract (for filling)
  • 1 to 2 tablespoons (1530 ml) milk (whole or almond milk)
  • Optional: pinch of salt (for filling)
  • Black fondant or black royal icing (for decoration)
  • Yellow or gold edible glitter or sprinkles (for tassels)
  • Food-safe paintbrush (for applying edible glue or water)

Instructions

  1. Preheat oven to 350°F (175°C). Line two baking sheets with parchment paper or silicone mats.
  2. In a medium bowl, whisk together flour, baking powder, and salt. Set aside.
  3. In a large bowl, beat softened butter and granulated sugar with an electric mixer on medium speed until light and fluffy, about 3-4 minutes.
  4. Beat in the egg and vanilla extract until fully incorporated.
  5. Gradually add the flour mixture to the butter mixture on low speed, mixing just until combined.
  6. Shape dough into a disk, wrap in plastic wrap, and refrigerate for at least 30 minutes.
  7. Roll dough on a lightly floured surface to about ¼-inch (6 mm) thickness. Cut out shapes using a graduation cap cookie cutter.
  8. Place cookies on baking sheets about 1 inch apart.
  9. Bake for 10-12 minutes until edges are just starting to turn golden. Let cool on the sheet for 5 minutes, then transfer to a wire rack to cool completely.
  10. For the frosting, beat softened butter until smooth. Gradually add powdered sugar, mixing on low speed.
  11. Add vanilla extract and milk until frosting is fluffy and spreadable.
  12. Spread frosting on the flat side of one cookie and gently press a second cookie on top to form a sandwich. Repeat for all cookies.
  13. Roll out black fondant and cut small squares to fit cookie tops. Attach with a dab of frosting or edible glue.
  14. Add tassels using yellow/gold edible glitter or sprinkles. Allow decorations to set before serving.

Notes

Chill dough well before rolling to prevent spreading. Use an offset spatula for easier frosting application. If dough gets sticky, refrigerate for 10 minutes. Avoid overbaking to keep cookies soft but sturdy. Assemble sandwiches only when cookies are completely cool to prevent frosting from melting. Decorations can be attached with edible glue or frosting. For gluten-free, use Bob’s Red Mill Gluten-Free Flour blend. For dairy-free, substitute vegan butter and plant-based milk.
