A perfectly soft and chewy sugar Funfetti cookie but in bar form so it’s easy to share with others. These customizable cookie bars are topped with a fantastic Funfetti frosting for a special touch!
Addie shared a birthday party with one of her friends a few short weeks ago. She and this little girl have known each other since they were 3 months old. They were both enrolled in the same daycare and have been friends ever since. Last year, they even shared the same kindergarten teacher.
The girl’s mom and I were discussing our birthday party plans for the year and just couldn’t get motivated. We wanted to do something low-key without breaking the bank so we decided to do a fun swim outing at our local YMCA. We invited about 15 girls, and unfortunately only 1 or 2 of them were able to attend.
Rather than pay the $150+ to rent out the party room at the YMCA, we canceled the party and held at our friend’s house. She ordered pizza and I bought an ice cream cake at the grocery store. Since I relinquished the cake to a grocery store this year, I figured that I could bake some Funfetti bars as an additional item.
The bars baked up beautifully, and I chose to use blue and white sprinkles to reflect Addie’s favorite colors (of the moment). She is still obsessed with Frozen so the color scheme was perfect for her. I added the same sprinkles to the frosting to finish the look. You can absolutely customize the sprinkles to whatever color or shape makes you happy.
The girls loved these bars and had no problem finishing them off along with a slice of ice cream cake. I think they were sugared up for the rest of the afternoon. But, it was worth it to see their little faces light up that day.
Funfetti sugar cookie bars
Ingredients
Cookie
- 1/2 cup (1 stick) unsalted butter, softened
- 1/2 cup brown sugar packed
- 1/2 cup granulated sugar
- 1 egg
- 2 teaspoons vanilla extract
- 1 teaspoon baking powder
- 1/2 teaspoon salt
- 2 and 1/2 cups all-purpose flour
- 1/2 cup sprinkles
Frosting
- 1/2 cup (1 stick) 1 stick unsalted butter, softened
- 2 teaspoons vanilla extract
- 1/2 teaspoon salt
- 3 and 1/2 cups powdered sugar
- 1/4 cup milk of choice
- sprinkles
Instructions
- Preheat your oven to 375 degrees F. Generously butter or grease a standard 9"x13" pan and set aside.
- In the bowl of a stand mixer fitted with the paddle attachment or in a large bowl if using a handheld mixer, cream the butter and sugars together on medium speed until light and fluffy, about 2-3 minutes. Add the egg and vanilla and mix well.
- Add in the baking powder and salt until well mixed. Turn the mixer to low and slowly add in the flour until no dry streaks remain. Add in the sprinkles.
- Transfer the batter to your prepared pan and spread it out evenly, making sure you cover all the corners. Smooth out the top. Bake in your preheated oven for 15 minutes or until the tops and sides are golden brown. Allow the bars to cool completely.
- While the bars are cooling, make the frosting. In the bowl of a stand mixer fitted with the paddle attachment or in a large bowl if using a handheld mixer, beat the butter on medium speed. Add in the vanilla and salt. Turn the mixer down to low and slowly add in the powdered sugar about 1/2 cup at a time. Slowly stream in the milk and beat until smooth and creamy. Fold in the sprinkles last.
- Once the bars have fully cooled, spread the frosting on top.
