These gooey funfetti bars feature a sweet gooey center, colorful sprinkles, and soft texture. Make them in one bowl in less than 30 minutes!


  • 1 cup unsalted butter, melted
  • 1 ¼ cup light brown sugar, packed
  • ½ cup sugar
  • 2 large eggs
  • 2 teaspoons clear vanilla extract
  • 2 ¼ cups all-purpose flour
  • ½ teaspoon baking powder
  • 1 1/4 teaspoons salt
  • ¾ cups rainbow sprinkles


  1. Preheat the oven to 350 degrees Fahrenheit and line an 8” square metal pan with aluminum foil. Spray lightly with baking spray and set aside.
  2. In a large bowl, stir together the butter, brown sugar, and sugar. Add the eggs and extract, stirring well to combine. Toss in the flour, baking powder, and salt, stirring until combined. Fold in the sprinkles.
  3. Spread the batter into the prepared pan. Bake in the preheated oven for about 23-25 minutes or until a toothpick inserted comes out with a few moist clumps. Allow to cool (or place in the fridge) until set completely and then slice. These bars are rich, so I recommend small squares. 😊
