Ingredients

Dry Ingredients

  • 2 ¾ cups all-purpose flour
  • 1 tsp baking soda
  • ½ tsp baking powder
  • ½ tsp salt

Wet Ingredients

  • 1 cup unsalted butter softened
  • 1 ½ cups granulated sugar
  • 1 large egg
  • 2 tsp vanilla extract
  • 2–3 tbsp milk only if needed for texture

For the Crunchy Coating

  • 1 cup rainbow nonpareils or more as needed

Instructions

Prep

  • Preheat oven to 350°F (175°C).
  • Line baking sheets with parchment paper.

Cream Butter + Sugar

  • In a large mixing bowl, beat butter and sugar together for 2–3 minutes until light and fluffy.

Add Egg + Vanilla

  • Mix in the egg and vanilla extract until smooth.

Add Dry Ingredients

  • Whisk flour, baking soda, baking powder, and salt in a separate bowl.
  • Add dry mixture to the wet ingredients and mix until a soft dough forms.
  • If the dough feels crumbly, add milk 1 tablespoon at a time until it becomes scoopable.

Scoop + Coat in Nonpareils

  • Scoop dough into 1.5 tbsp balls.
  • Roll each ball in rainbow nonpareils OR press the tops firmly into nonpareils to create a thick crunchy layer.

Bake

  • Place cookies 2 inches apart on the baking sheet.
  • Bake 10–12 minutes, until edges are set but centers look soft and slightly underbaked.
  • Let cool on the pan for 5 minutes before transferring to a rack.

Notes

  • Don’t overmix the dough: Mix just until the flour disappears. Overmixing can make the cookies tough instead of soft and tender.
  • Roll cookies gently in nonpareils: Pressing too hard can flatten the dough and cause uneven baking. A gentle roll or press into the sprinkles creates a perfect crunchy shell.
  • Chill for thicker cookies: If you want the cookies to spread less, chill the dough for 20–30 minutes before baking.
  • Use room-temperature butter: It creams better and creates a lighter, softer cookie texture.
  • Nonpareils work better than jimmies: They stay crisp during baking and add a more satisfying crunch.
  • Add almond extract (optional): A small amount — ¼ to ½ teaspoon — adds a bakery-style flavor that pairs beautifully with sugar cookies.
  • For extra soft centers: Pull cookies out of the oven when the centers still look slightly underbaked. They set as they cool.
  • Color variations: Use seasonal nonpareils (pastel, Halloween, Christmas, red/white/blue, Valentine’s) for instant holiday-themed cookies.
  • Storage: Store in an airtight container at room temperature for up to 4 days. Freeze baked cookies or uncooked dough balls for up to 2 months.
