Cake Batter

These soft, chewy birthday cake batter cookies pack bold “boxed-cake” flavor thanks to cake batter extract and a kiss of vanilla. You’ll cream butter and sugars, mix in egg and milk for tenderness, then add cake batter extract, vanilla, and dry ingredients. Fold in rainbow sprinkles and white chocolate chips for that classic funfetti look, chill to keep the cookies thick, then bake until the edges are set and the centers stay soft. Finish with extra sprinkles while warm for picture-perfect cookies that taste like a slice of birthday cake in every bite.

Ingredients

  • 2 ¼ cups (280 g) all-purpose flour

  • 1 tsp cornstarch

  • ½ tsp baking soda

  • ½ tsp fine salt

  • ¾ cup (170 g) unsalted butter, softened

  • ¾ cup (150 g) granulated sugar

  • ½ cup (100 g) light brown sugar, packed

  • 1 large egg, room temperature

  • 2 Tbsp milk

  • 1½ tsp cake batter extract

  • 1 tsp pure vanilla extract

  • ¾ cup white chocolate chips

  • ½ cup rainbow jimmies sprinkles, plus extra for topping

Directions

  1. Whisk the dry ingredients: In a bowl, whisk flour, cornstarch, baking soda, and salt until evenly combined for perfect cake-batter-cookie texture.

  2. Cream for lift: In a separate large bowl, beat butter, granulated sugar, and brown sugar on medium-high until pale and fluffy, 2–3 minutes.

  3. Add wet flavors: Beat in egg and milk until smooth, then mix in cake batter extract and vanilla for concentrated birthday-cake flavor.

  4. Combine: Add dry ingredients to wet on low speed just until a soft dough forms—do not overmix.

  5. Fold-ins: Stir in white chocolate chips and sprinkles. Cover and chill 30 minutes to keep cookies thick and chewy.

  6. Bake: Preheat oven to 350°F (175°C). Scoop 2 Tbsp mounds (about 40 g) onto parchment-lined sheets, spacing 2 inches apart. Bake 10–12 minutes until edges set and centers look slightly underbaked.

  7. Finish & set: While warm, dot with extra sprinkles. Cool on the sheet 5 minutes, then move to a rack to finish setting. Enjoy ultra-soft, bakery-style cake batter extract cookies!
