Funfetti Cake Mix Cookies are like a birthday cake in cookie form! These easy funfetti cookies are giant, soft cookies that are rolled in sprinkles for a fun and festive cookie.

Funfetti Cake Mix Cookies

I absolutely love the flavor of funfetti. I'm not sure what exactly goes into that "cake batter" "birthday cake" flavoring, but oh man it's SO good! I love making desserts like my Funfetti Ice Cream Cake and Funfetti Ice Cream Sandwich Bars, so I decided to create my own bakery-style Funfetti Cake Mix Cookies.

Funfetti Cake Mix Cookies

These funfetti cookies are seriously so dang good. The first couple of times that I test them, they kept spreading out too thin. The flavor was great but I wanted these cookies to be giant but also thick and sturdy. I also decided I didn't care if I had to use a box of funfetti cake mix to get that funfetti flavor. These cookies are made with a combination of cake mix and flour, so I'd call them semi-homemade. The other key to making them is starting with cold butter. If you start with room temperature butter, they will spread out too thin.

Cold, Unsalted Butter - starting with cold butter will keep them from spreading out too thin.

How to Make Giant Funfetti Cookies

Preheat the oven. First, preheat the oven to 375 degrees F and lining a couple of baking sheets with parchment paper.

Beat the butter. This cookie recipe starts by beating the cold butter until it's creamy. You want to get it creamy so it won't be clumpy once you add the sugar.

Add the sugar and eggs. After the butter is creamy, you'll add the sugar and beat until combined, followed by the eggs and egg yolk. The addition of the egg yolk adds a little extra fat and makes the cookies chewy.

Add the dry ingredients. Next, add the baking powder, baking soda, and salt, and mix to combine. Lastly, add the cake mix followed by the flour, mixing until it is all one unified dough.

Form into cookie balls. The dough gets made into giant cookie dough balls by using a ½ cup measuring cup. I sprayed mine with cooking spray to make it easier to get the dough out.

Sprinkles. Once the dough balls are formed, roll them in funfetti sprinkles. Next, you'll spread them out onto a couple of baking sheets. I found that three cookies fit on one baking sheet and I baked mine one sheet at a time to ensure even baking. The recipe makes 8 cookies so it will take a few rounds of baking.

Bake. Bake the cookies for 10-11 minutes, which will get the edges slightly golden and the middle cooked just enough that they will be baked but not doughy and not overbooked! We are going for chewy. Since they are such large cookies, it's important to cool them completely. Cool them them for 10-15 minutes on the baking sheet and then carefully transfer them to a cooling rack with a spatula so they cool completely. By the time they are cool, they should be sturdy.

Enjoy. That's it! You're on your way to the best giant funfetti cookies you've ever had!

Tips for the Best Funfetti Cake Mix Cookies

Make them big enough. Make sure the cookie dough balls are ½ cup. This recipe makes 8 cookies, so if you have more cookie dough balls than that, you're not making them big enough.

Don't over bake. The cookies will seem underbaked when you take them out of the oven. They shouldn't be shiny on top, that means they need another minute or two, but they will seem not completely cooked. They WILL set up as they cool! These cookies are best when cooled completely.

Start with cold butter. This will ensure the cake mix cookies don't spread out too thin.
