Ingredients

Scale
  • 2 ¾ cups (345g) all-purpose flour, sifted
  • 1 teaspoon baking powder
  • ½ teaspoon salt
  • 1 cup (227g) unsalted butter, softened
  • 1 ½ cups (300g) granulated sugar
  • 1 large egg, room temperature
  • 1 teaspoon pure vanilla extract
  • 2 tablespoons milk (whole or 2%, optional)
  • ½ cup funfetti sprinkles (rainbow nonpareils, no bleed)
  • 3 cups (360g) powdered sugar, sifted
  • 2 large egg whites (or 4 tablespoons meringue powder mixed with 6 tablespoons water for no-egg version)
  • ½ teaspoon cream of tartar
  • Yellow gel food coloring
  • Black gel food coloring
  • Optional: a few drops of lemon juice

Instructions

  1. Mix dry ingredients: whisk together flour, baking powder, and salt in a medium bowl; set aside.
  2. Cream butter and sugar: beat softened butter with granulated sugar on medium speed until light and fluffy, about 3-4 minutes.
  3. Add egg and vanilla: beat in egg and vanilla extract until combined, scraping down sides.
  4. Incorporate dry ingredients: gradually add flour mixture to wet ingredients on low speed; add milk if dough is too stiff. Mix just until combined.
  5. Fold in funfetti sprinkles gently with a spatula.
  6. Chill dough: shape into a disk, wrap in plastic, refrigerate at least 1 hour.
  7. Preheat oven to 350°F (175°C). Line baking sheets with parchment paper or silicone mats.
  8. Roll dough on lightly floured surface to ¼ inch (6mm) thickness. Cut shapes with school bus cookie cutter and place 2 inches apart on baking sheets.
  9. Bake 8-10 minutes until edges start to golden but centers remain soft. Cool on sheets 5 minutes, then transfer to wire racks to cool completely.
  10. Prepare royal icing: beat powdered sugar, egg whites, and cream of tartar until stiff peaks form (7-10 minutes). Divide into two bowls; color one yellow, one black with gel food coloring. Adjust consistency with water for piping or flooding.
  11. Decorate: outline cookies with thicker yellow icing, flood inside with thinner yellow icing. After 15 minutes, add black details for windows and wheels. Let dry completely for several hours or overnight.

Notes

Chill dough for at least 1 hour to prevent spreading and keep colors vibrant. Mix dough just until combined to avoid tough cookies. Keep icing tools clean and dry for best royal icing results. Adjust icing consistency with water or powdered sugar as needed. Let decorated cookies dry overnight for best stacking and packaging.
