Ingredients

Scale
  • 2 ½ cups (315 grams) all-purpose flour
  • 1 teaspoon baking soda
  • ½ teaspoon salt
  • 1 cup (226 grams) unsalted butter, softened
  • ¾ cup (150 grams) granulated sugar
  • ½ cup (110 grams) packed brown sugar
  • 2 large eggs, room temperature
  • 2 teaspoons pure vanilla extract
  • ½ cup (120 ml) sour cream
  • ¾ cup (about 100 grams) rainbow star-shaped sprinkles
  • 8 ounces (227 grams) cream cheese, softened
  • ½ cup (113 grams) unsalted butter, softened (for frosting)
  • 3 cups (360 grams) powdered sugar, sifted
  • 1 teaspoon pure vanilla extract (for frosting)
  • 12 tablespoons (1530 ml) milk or cream (optional, for frosting consistency)

Instructions

  1. Preheat your oven to 350°F (175°C). Grease a 9-inch cake pan thoroughly with butter or non-stick spray, then lightly dust with flour. Set aside.
  2. In a medium bowl, whisk together the flour, baking soda, and salt. Set aside.
  3. In a large bowl, beat the softened butter with granulated sugar and brown sugar until light and fluffy, about 3-4 minutes on medium speed.
  4. Beat in the eggs one at a time, then add the vanilla extract and mix until combined.
  5. Fold in the sour cream gently to keep the batter tender and moist.
  6. Gradually add the dry ingredients to the wet ingredients, mixing just until combined. Avoid over-mixing.
  7. Fold in the rainbow star-shaped sprinkles carefully to avoid color bleeding.
  8. Spread the batter evenly in the prepared cake pan and smooth the top with a spatula.
  9. Bake for 30-35 minutes, checking at 30 minutes with a toothpick. It should come out with a few moist crumbs but no raw batter. The edges will be golden.
  10. Allow the cookie cake to cool in the pan for at least 20 minutes, then transfer to a wire rack to cool completely before frosting.
  11. To make the frosting, beat the softened cream cheese and butter until smooth. Gradually add powdered sugar and vanilla extract, beating until fluffy. Add milk or cream if needed to reach desired consistency.
  12. Spread the frosting evenly over the cooled cookie cake. Optionally, sprinkle a few more star-shaped sprinkles on top.
  13. If frosting is too soft, chill the cake in the fridge for 15 minutes before slicing.
  14. Slice into wedges and serve.
