These birthday cake sugar cookies are soft, sweet, and loaded with rainbow sprinkles - everything you could ever want from an easy birthday themed treat!


  • 280g (2 1/3 cups) all-purpose flour
  • 1/2 tsp baking powder
  • 1/2 tsp baking soda
  • 1 tsp kosher salt
  • 170g (3/4 cup) unsalted butter, room temp
  • 150g (3/4 cup) granulated sugar
  • 106g (1/2 cup) light brown sugar
  • 1 egg, room temp
  • 2 tsp vanilla extract
  • 48g (1/4 cup) rainbow jimmies sprinkles


  1. In a medium size bowl, combine the flour, baking powder, baking soda, and salt. Set aside.
  2. In the bowl of a stand mixer, beat the butter and sugars together until light & fluffy, about 2-3 minutes.
  3. Add the egg and vanilla and beat until fully incorporated. 
  4. Scrape down the bowl, then add the dry ingredients and mix until just combined. Do not over-mix!
  5. Gently fold in the sprinkles. 
  6. Using a 2 tbsp cookie scoop, portion the cookie dough and place on one baking sheet lined with parchment paper. Freeze the cookie dough for 30 minutes. 
  7. Meanwhile, preheat the oven to 350 degrees F, and line two large baking sheets with parchment paper.
  8. Place the frozen cookie dough on one prepared baking sheet placed about two inches apart.
  9. Bake the cookies for about 10 minutes. Allow cookies to cool completely on the baking sheet, and enjoy! 


  • Use a cookie scoop. Use a 2 tablespoon cookie scoop to portion the cookie dough into equally sized cookies!
  • Freeze the portioned cookie dough. To ensure the cookies bake up to the right thickness, don't skip the freeze time!
  • Scoot the cookies. Immediately after the cookies come out of the oven, use a large round cookie cutter or glass to scoot the edges and form a perfectly round cookie.
