Ingredients

1 cup (226 g) unsalted butter melted
1 cup (213 g) brown sugar
½ cup (100 g) granulated sugar
2 large eggs room temperature
1 ½ teaspoons vanilla extract
½ teaspoon almond extract
2 ¼ cups (270 g) all-purpose flour *measured properly
1 teaspoon salt
1 teaspoon baking soda
½ cup (80 g) rainbow sprinkles
12 ounces (340 g) white chocolate chips

Instructions

Preheat oven to 350F. Line a 9x13 baking pan with parchment paper and set aside.
In a large bowl, add melted butter, brown sugar, and granulated sugar. Stir to combine. Add eggs, vanilla extract, and almond extract and stir until incorporated.
In a separate bowl, sift together the flour, salt, and baking soda. Gradually stir dry ingredients into butter mixture until just combined. Add sprinkles and white chocolate chips and gently stir until just combined.
Pour batter into 9x13 pan and use a spoon to spread evenly to the edges.
Bake for about 25 to 30 minutes, or until evenly browned across the top and set in the center. Use a toothpick in the center to check for doneness. Remove from oven and allow to cool before slicing and serving.

Notes

* How to measure flour properly: Use a kitchen scale to measure flour for accurate results every time. If you don't have a kitchen scale, use the spoon and level method. Stir the flour (especially if it's been packed down in a bag/container), then gently spoon into the measuring cup, leveling off the top with a knife. Scooping with a measuring cup compacts flour into the cup and adds up to 25% extra to the recipe, resulting in dry, bland bars.
Storage: Cookie bars will keep for 5-7 days in a sealed container. To help keep bars fresh, place a slice of bread in the container with the bars. Replace the bread slice as needed.
Freezing: Cookie bars freeze well, up to 3 months in a sealed plastic container or freezer bag.
