Start by preheating your oven to 350 degrees and prepping a 9x13 pan. I used this nonstick brownie pan but you can also use a ceramic or glass pan. Just be sure to adjust your baking time up a few minutes. Even with a nonstick pan, paranoid me still sprays it with nonstick spray or lines it with parchment paper. Better safe than scraping up stuck pieces of cookie bar!
With a hand mixer, beat the ¾ cup butter, granulated sugar, and brown sugar on high until well combined, light, and fluffy.
Add the eggs and vanilla extract to the mixing bowl and beat on medium speed until fully combined.
Add the box cake mix ½ cup at a time and beat on low speed between each addition until you have a consistent dough.
With a rubber spatula, spread the cookie dough out evenly throughout the pan and bake for 15-17 minutes.
HINT: When spreading the cookie dough across the baking pan, spray the spatula with nonstick spray to help prevent the dough from sticking to it.
I used my hand mixer for this recipe because it's easy to clean and I didn't feel like dragging up my kitchen aid from the basement. However, if you have a stand mixer, feel free to use it with the paddle attachment for this recipe.
Bake these lazy cookie bars until the edges are light brown and the top is golden brown. The lower end of the baking time will produce more gooey cake bars.
Allow the cake bars to cool for about 10-15 minutes in the cake pan before removing them and cutting into squares. They can be enjoyed plain or topped off with frosting! If you are frosting them, make sure the bars cool completely beforehand.
I think a regular vanilla or white canned frosting goes really well with these cake bars, and is also the easiest option. However, if you aren't a fan of the can, try this Almond Buttercream recipe or this Margarita Frosting recipe.
If you don't have Funfetti box mix, you can use a white cake mix, vanilla cake mix, or make these into yellow cake mix cookie bars too! I did not test it, but I bet the strawberry cake mix would make great cookie bars as well.
Feel free to add any mix-ins into the cookie dough such as chocolate chips, white chocolate chips, butterscotch chips, peanut butter chips, or even extra sprinkles.
You can also serve these warm right out of the oven with a scoop of vanilla ice cream!
Keep the cookie bars sealed in an airtight container for up to 5-7 days. These containers are my favorite.
I hope these easy cake mix cookie bars are the perfect quick dessert for your next party or sweet tooth craving!
