Funfetti Sugar Cookie Bars

Please share

Funfetti sugar cookie bars are soft, delicious and covered in sprinkle filled buttercream. Plus when you bake cookies as bars, it makes everything so quick and easy with no chilling of the dough or rotating trays of cookies through the oven.

If you love soft sugar cookies topped with frosting, you are going to love these yummy sprinkle filled cookie bars. They are perfect for birthdays, parties and more.

You start by making a dough based on butter and cream cheese. The cream cheese helps to keep that super soft texture in the final bars.

Add in the standard cookie ingredients like sugar, eggs, vanilla and flour. Then you stir in a whole cup of colorful sprinkles.

Use colors to match your party theme or use a standard mix. Just be sure to use the longer jimmy style sprinkles, not the smaller ball style nonpareils.

The nonpareil sprinkles have a tendency to melt into the dough and create a muddled effect. The larger sprinkles tend to have more distinct color bits after baked.

Little Dude created the sprinkle mix we used and he had a great time combining the colors. So do whatever makes you happy.

Press the dough into a 10×15-inch pan. It makes the perfect thickness of cookie.

However, if you don’t have a 10×15, you can use a 9×13. Just add a few minutes to the bake time to make up for the addition depth.

The cookies will be extra thick, but if you family is like mine, that won’t be a problem!

Decorating your Funfetti Cookie Bars

These cookies are fabulous on their own. They aren’t overly sweet and are super fun.

But adding frosting to the top makes them even more fun. We made a batch of funfetti buttercream to put on them.

You could use a plain crusting buttercream if you prefer or dye it a fun color. Then add a few more sprinkles on top to really drive the point home.

We piped simple stars on our bars for more fun. Just be sure to use a large tip if you are using funfetti buttercream so the sprinkles don’t clog the tip.

You can just spread the frosting on top if you prefer. Either way, it is going to look great and taste amazing.
