  • 1 1/4 cup (250g) granulated sugar
  • 3/4 cup (1 1/2 sticks or 170g) unsalted butter room temperature
  • 2 teaspoons baking powder
  • 1 teaspoon salt
  • 1 tablespoons McCormick vanilla extract
  • 1/2 teaspoon McCormick almond extract
  • 2 large eggs room temperature
  • 3 cups (384g) all-purpose flour
  • 2/3 cup whole milk room temperature
  • 3/4 cups Rainbow Jimmies


  • Preheat oven to 400°F. Line 3 baking sheets with parchment paper.
  • Add sugar and butter together in a large bowl and beat with a hand-held mixer until light and creamy, about 2 minutes.
  • Add baking powder, extract, and salt, and mix until combined.
  • Add eggs, one at a time, until completely combined. Scrape the sides of the bowl as needed.
  • Alternate adding the flour and milk to the butter mixture and mix until completely combined. (Do not overmix)
