Description

Sweet, colorful, and full of celebration vibes, these blondies are made from a yellow cake mix and loaded with rainbow sprinkles — perfect for birthdays or any fun occasion!


Ingredients

  • 1 (15 oz) box yellow cake mix
  • ¼ cup vegetable oil
  • 3 tablespoons whole milk
  • 1 large egg
  • 1 tablespoon vanilla extract
  • ½ cup rainbow sprinkles

Instructions

  1. Preheat the oven: Preheat the oven to 350°F. Grease a 9×9-inch baking pan or line with parchment paper.
  2. Make the Batter: In a mixing bowl, combine the cake mix, oil, milk, egg, and vanilla extract. Mix until well blended — batter will be stiff.
  3. Fold in Sprinkles: Fold in the rainbow sprinkles.
  4. Spread the Batter: Spread the batter evenly into the prepared pan using a rubber spatula.
  5. Bake: Bake for 30 to 35 minutes, or until a toothpick inserted into the center comes out clean.
  6. Cool: Let blondies cool for a couple of hours before cutting for best results.

Notes

  • For an extra fun touch, top with more sprinkles before serving.
  • For a different flavor, try using chocolate or vanilla cake mix.
  • Store leftovers in an airtight container for up to 3 days.
