These easy Funfetti Sugar Cookie Bars are made and frosted in one pan. A soft chewy cookie recipe with sprinkles and vanilla buttercream frosting will get smiles from everyone!
Change up the frosting color and sprinkles for any party or holiday.
A few years ago I realized just how easy it was to make sugar cookies in a pan. Since then I have not spent any time at all with my big box of cookie cutters.
I'm all for saving time by baking and frosting cookies in one pan! Who is with me?
Let's talk about sprinkles for a minutes. I may love sprinkles a little too much because I think there are at least 50 jars of different colors and kinds lurking in our cupboards.
I mean, you never know when a batch of Funfetti Cookies and Cream Fudge might need to happen, right? Sprinkles just make a dessert so much prettier.
Although, there are a few people in our house who don't seem to agree with me and brush said sprinkles off when I use them. I'm pretty sure I live with aliens!
Since I started making frosted sugar cookie bars, I have not rolled a single batch of cookie dough in our kitchen. I was completely serious when I said I gave up my cookie cutters.
Got to love baking and frosting cookies in one pan, right?
Ingredients for Cookie Bars:
- Butter - Be sure to set the butter out ahead of time, so it is easier to mix with the other ingredients. I always use unsalted butter in my recipes and adjust with additional table salt.
- Sugar - A mixture of brown and granulated sugar sweetens and softens the dough.
- Egg - The moisture that binds the dough together.
- Vanilla - Adds a sweet flavor.
- Flour - Gives the cookies structure as it bakes.
- Baking Powder - Using just a little helps to lift the dough as it bakes.
- Salt - Balances out the sweetness in the dough and frosting.
- Sprinkles - It would not be a Funfetti cookie without lots of sprinkles. Make sure you use jimmie sprinkles in the dough and to decorate the top of the vanilla frosting.
The best thing about these sugar cookie bars with sprinkles is that you can match the color of sprinkles to your party.
Use a mix of blue or pink sprinkles to make these perfect for a baby shower. A red and green mix would be great for Christmas and a red, white, and blue mix would be so pretty for Fourth of July.
We also love making these Shamrock Shake Sugar Cookie Bars for St. Patrick's Day and these Eggnog Sugar Cookie Bars for Christmas. Sugar cookie bars are so versatile when it comes to flavors and colors.
Lots of rainbow sprinkles make these cookie bars a fun and easy dessert.
How to make Funfetti Sugar Cookie Bars:
- Beat the softened butter and sugars until light and creamy.
- Add the egg and vanilla and mix again.
- Slowly mix in the dry ingredients and until a dough forms.
- Gently stir in sprinkles.
- Press cookie dough evenly in the bottom of a greased pan and bake.
- Cool completely before frosting.
Why is my dough dry and crumbly?
Did you let the butter sit out and get soft? Are you using a hand mixer or a stand mixer? If your butter is still cold OR you are using a hand mixer, it will take longer for the dough to come together. Just keep mixing.
Can these sugar cookie bars be made ahead of time?
Yes. This is one of those recipes that gets better the longer it sits. I actually recommend making them a day ahead of time for best flavor and texture.
How do you store frosted cookie bars?
Keep them in a tightly sealed container at room temperature, so they stay soft and delicious for longer.
Can you freeze sugar cookie bars?
Freeze the unfrosted bars in a tightly wrapped and sealed container for up to 3 months. Thaw overnight, then add the frosting and sprinkles.
You can also freeze the frosted cookie bars in a tightly sealed container.
