Description
These thick, chewy funfetti blondies are buttery, soft-centered, and exploding with color. Made in one bowl—no mixer needed—they’re perfect for birthdays, bake sales, or just brightening someone’s day. We’ve doubled the batch and added a few irresistible twists for even more flavor and texture. Sweet, salty, colorful… these are pure joy in bar form.
Ingredients
2 cups unsalted butter, melted and slightly cooled
2 cups packed brown sugar
1 cup granulated sugar
2 tbsp vanilla extract
2 tsp salt
2 tsp baking powder
2 tbsp cornstarch
3 cups all-purpose flour
2 cups white chocolate chips
1 cup rainbow sprinkles (jimmies work best)
½ cup chopped golden Oreos (optional, for crunch)
½ cup mini marshmallows (optional, for gooey pockets)
Instructions
Preheat oven to 350°F (175°C). Grease or line a 9×13″ pan with parchment paper.
In a large mixing bowl, combine melted butter, brown sugar, and granulated sugar. Stir until smooth.
Add vanilla, then stir in salt, baking powder, and cornstarch.
Gradually mix in flour until fully incorporated.
Fold in white chocolate chips, rainbow sprinkles, golden Oreos, and mini marshmallows (if using).
Spread batter evenly into prepared pan. For extra flair, sprinkle a few extra chips and sprinkles on top.
Bake for 30–35 minutes, or until the edges are set and the center looks slightly underbaked (they’ll continue to set as they cool).
Cool completely before slicing into bars.
