# Ingredient List:
→ Bars
01 - 1 cup unsalted butter, softened
02 - 1 cup granulated sugar
03 - 1/2 cup light brown sugar, packed
04 - 2 large eggs, room temperature
05 - 2 teaspoons pure vanilla extract
06 - 2 cups all-purpose flour
07 - 1/2 teaspoon baking powder
08 - 1/2 teaspoon salt
09 - 1/2 cup rainbow sprinkles (jimmies preferred)
→ Cinnamon Sugar Topping
10 - 1/4 cup granulated sugar
11 - 1 tablespoon ground cinnamon
# Directions:
01 - Preheat oven to 350°F. Line a 9x9-inch baking pan with parchment paper, leaving an overhang on two sides for easy removal.
02 - In a large bowl, use an electric mixer or whisk to cream the softened butter, granulated sugar, and light brown sugar until the mixture is light and fluffy, about 2–3 minutes.
03 - Add eggs and pure vanilla extract to the creamed mixture and beat until well combined.
04 - In a separate bowl, whisk together all-purpose flour, baking powder, and salt.
05 - Gradually add the dry ingredients to the wet mixture, mixing just until incorporated. Do not overmix.
06 - Gently fold rainbow sprinkles into the dough using a rubber spatula.
07 - Transfer dough to the prepared pan, spreading it evenly and smoothing the top.
08 - In a small bowl, mix granulated sugar and ground cinnamon. Sprinkle evenly over the surface of the batter.
09 - Bake in preheated oven for 28–32 minutes, until the edges are set and golden and a toothpick inserted in the center comes out clean.
10 - Place pan on a wire rack and cool completely. Lift out the bars using the parchment overhang and slice into equal portions.
