Why I love these funfetti blondies:
- Thick & chewy: These are everything you want from a cookie bar; thick, soft, chewy, and packed with a sweet & salty flavor!
- One bowl, no mixer required! Because we're using melted butter, no mixer is required to make these funfetti blondies! If you do use a mixer, be sure to only mix until the ingredients are incorporated; overmixing will result in a more cake-like texture.
- Made in 9x13 pan: After developing my chewy funfetti cookie cake, I knew I needed to try them thicker in a 9x13 pan! These would even be perfect to make as a rectangle cake by piping a border of the frosting from my cookie cake recipe!
Ingredient Notes & Tips
- Use a higher-quality white chocolate chip: While I use generic chips all the time, white chocolate chips are one that I don't like to cut corners on. The generic ones often taste waxy and artificial, which will affect the overall flavor of your cookie (trust me, I tried it and it was not good). I use Ghiradelli or Nestle white chocolate chips, which both have a good flavor.
- Sprinkles: Jimmies sprinkles work best; avoid anything with pearls as they will bleed and be too crunchy. Also, test out the flavor and only use sprinkles that you like the taste of. Some sprinkles have a fake, bad flavor and will ruin the flavor of the cookie.
- Don't overbake: The trick to a soft, chewy texture is to only bake until the edges are lightly brown. You also want to allow the bars to fully cool before slicing (they can look doughy when warm).
- Mix by hand: Because this uses melted butter, you don't need a high-powered mixer. The trick to a chewy texture is to just mix the ingredients until incorporated!

Instructions
- Preheat oven to 350ºF. While preheating, be sure to read tips & tricks in post above for recipe success.
- Warm the 1 cup unsalted butter (not margarine), i.e. 2 sticks[/adjustable] in a microwave-safe bowl or saucepan until it's just melted. If steaming, allow to cool for a few minutes before proceeding.
- In a large mixing bowl, combine the unsalted butter with the 1 cup light brown sugar and 1 cup granulated sugar. Stir until combined. (I recommend mixing this by hand rather than a mixer.)
- Stir in 2 large eggs and 1 tablespoon vanilla extract, followed by the 1 teaspoon baking powder and 1 ½ teaspoons salt.
- Mix in 1 tablespoon cornstarch and 2 ½ cups all-purpose flour, followed by the 1 cup white chocolate chips and ½ cup rainbow sprinkles. Mix the dough until well-combined. This is a "wetter" dough but if it is runny, let it sit and firm up for a few minutes (or add 1-2 tablespoons more flour).
- Grease and line a 9x13 light-metal pan with parchment paper. Spread dough into an even layer in pan. If desired, press some extra sprinkles on top for added presentation.
- Bake for 28-32 minutes at 350℉, or until edges are slightly golden brown. The center may look slightly underbaked but the residual heat from the pan will continue to bake the bars even after you take it out of the oven.
- Cool completely before slicing into 12-24 squares.
Notes from Melissa
White Chocolate Chips: While I use generic chips all the time, white chocolate chips are one that I don't like to cut corners on. The generic ones often taste waxy and artificial, which will affect the overall flavor of you cookie (trust me, I tried it and it was not good). I use Ghiradelli white chocolate chips, which are well worth the extra dollar!
Sprinkles: Jimmies sprinkles work best; avoid anything with pearls as they will bleed and be too crunchy. Also, test out the flavor and only use sprinkles that you like the taste of. Some sprinkles have a fake, bad flavor and will ruin the flavor of the cookie (they might be fine for topping in small amounts but not to put in the dough!).
This was probably the most easiest recipe I've ever followed, and the blondies came out amazing despite the fact I mess up almost every other recipe I've ever done. THANK YOU SO MUCH for making this available for everyone, it was just lovely to follow and I'm looking forward to making another batch - great work and thanks again!
Taste was great! The baking on the other hand—time was not enough for the thickness of the bar. I let it bake full time plus 5 mins. I would highly suggest larger pan or longer baking time. Will try again and see what happens. Still tasty even if I had to throw out 2/3’s because it was too undercooked to eat without a spoon 😕
A big hit with kids, friends and family. Soft and chewy.
