Ingredients

Dry Ingredients

  • 1 ½ cups all-purpose flour (217 g)
  • 2 teaspoons corn starch
  • ½ teaspoon sea salt
  • ½ teaspoon baking soda

Wet Ingredients

  • ½ cup unsalted butter, softened to room temperature (113 g)
  • ¾ cup granulated sugar (150 g)
  • ¼ cup brown sugar (50 g)
  • 1 large egg
  • 1 ½ teaspoons vanilla extract

Add-ins

  • ½ cup rainbow sprinkles

Instructions

  1. Combine Dry Ingredients: In a small bowl, whisk together the flour, sea salt, corn starch, and baking soda until evenly mixed. Set aside.
  2. Cream Butter and Sugars: In a large bowl, beat the softened butter, granulated sugar, and brown sugar together using a mixer on medium speed until light and fluffy, about 2 to 4 minutes.
  3. Add Egg and Vanilla: Beat in the egg and vanilla extract until fully incorporated and the mixture is smooth.
  4. Mix Dry Ingredients into Wet: Gradually add the dry ingredient mixture to the wet ingredients, mixing just until combined. Avoid over mixing to keep cookies tender.
  5. Fold in Sprinkles: Gently fold the rainbow sprinkles into the dough to evenly distribute them without breaking them up.
  6. Chill Dough: For the best texture, roll the dough into 1 to 1 ½ inch balls, place them on a tray, and chill for about 15 minutes.
  7. Preheat Oven: While the dough chills, preheat your oven to 350°F (175°C).
  8. Bake Cookies: Arrange dough balls spaced about 2 inches apart on a parchment paper-lined baking sheet. Bake for 9 to 11 minutes. Cookies will puff up and might not look completely done, so remove them just before they appear fully baked to maintain softness.
  9. Cool: Let the cookies cool on the baking sheet for 2 to 3 minutes, then transfer them to a wire rack to cool completely.
  10. Store and Enjoy: Store cooled cookies in an airtight container for 3 to 5 days to maintain freshness. Enjoy your celebratory treats!

Notes

  • Do not over mix the dough after adding flour to avoid tough cookies.
  • Chilling the dough helps maintain cookie shape and enhances texture.
  • Baking time may vary based on oven; watch carefully to remove cookies before overbaking for the best soft texture.
  • Use parchment paper to prevent sticking and for easy cleanup.
  • Rainbow sprinkles add fun and color but can be substituted with chocolate chips or other small mix-ins.
