# What You'll Need:
→ Dry Ingredients
01 - 2 cups all-purpose flour
02 - 1 1/2 teaspoons baking powder
03 - 1/2 teaspoon baking soda
04 - 1/4 teaspoon salt
05 - 1/3 cup rainbow sprinkles
→ Wet Ingredients
06 - 2 large eggs
07 - 1 cup whole milk
08 - 1/2 cup sour cream
09 - 1/3 cup granulated sugar
10 - 1/4 cup unsalted butter, melted and cooled
11 - 1 teaspoon vanilla extract
→ Topping
12 - 1 cup shredded mild cheddar cheese
13 - 1/4 cup mini chocolate chips
14 - Extra rainbow sprinkles, for garnish
# Step-by-Step:
01 - Preheat oven to 350°F. Line a 9x13-inch baking pan with parchment paper, leaving an overhang for easy removal.
02 - In a large bowl, whisk together the all-purpose flour, baking powder, baking soda, and salt. Fold in the rainbow sprinkles evenly.
03 - In a separate bowl, whisk together the eggs, whole milk, sour cream, granulated sugar, melted unsalted butter, and vanilla extract until smooth.
04 - Add the wet mixture to the bowl of dry ingredients and stir just until combined. Do not overmix; stop when no streaks of flour remain.
05 - Transfer the batter into the prepared baking pan and spread it evenly. Distribute shredded mild cheddar cheese, mini chocolate chips, and additional sprinkles across the surface.
06 - Bake for 22 to 25 minutes, or until the edges are golden and a toothpick inserted into the center comes out clean.
07 - Allow to cool in the pan for 10 minutes. Use the parchment overhang to lift the bars out and cut into 12 equal portions. Serve warm or at room temperature.
