These Cake Mix Cookie Bars are the best funfetti gooey bars you will ever make! They are made with cake mix and then add white chocolate chips and sprinkles – you can’t go wrong. This is my first ever viral recipe – can you see why?
Funfetti Gooey Bars
These gooey bars are one of my favorite sweet treats, especially these funfetti ones: I can never get enough sprinkles! I made mine with cake mix because it makes the recipe easier and the sweetened condensed milk puts the ‘gooey’ into gooey bar!
This is the first recipe of mine that went truly viral on all social media – and the blog. Can yo see why? There is nothing bad about this recipe – the batter has the taste of cake – with colorful sprinkles. This is one of my favorite easy dessert recipes in the entire world!
Ingredients Needed
- Yellow Cake Mix: You can use any brand – but make sure it’s approximately 15 ounces. (I’ve also made this recipe with red velvet cake mix!)
- Butter: I always use unsalted butter – make sure it’s room temperature (softened)
- Sprinkles: Can’t have funfetti without the sprinkles! I use rainbow jimmies – be sure to use a high quality brand so they don’t melt in your batter. You can use any colors.
- Sweetened Condensed Milk: Regular or nonfat can be used.
- White Chocolate Chips: These can be omitted, or you can use chocolate to make chocolate chip cookie bars!
How to make Cake Mix Gooey Bars
- Add cake mix, butter, and egg to a large bowl. Mix with a hand mixer (you can also use a stand mixer). It will take awhile to mix the dough together (longer with a hand mixer) but it will turn into a thick cookie dough.
- Press about half to two-thirds of the dough into the bottom of your baking dish with your rubber spatula or hands. Pour sweetened condensed milk over the top of the dough, leaving a thin border around the edges. Sprinkle with white chocolate chips.
- Separate remaining dough into small balls and evenly space over the top of the bars. Press down to flatten. Try to seal the edges as much as possible.
- Bake bars for about 25-30 minutes, or until they just begin to get golden brown around the edges. Cool completely before slicing, otherwise the mixture will be too gooey to cut.
Expert Tips
- Recipes that use cake mix are so fun because you can make other recipes with different flavors of cake mix! I love making gooey bars with chocolate cake mix, white cake mix, even lemon cake mix or strawberry cake mix!
- I do not recommend using nonpareils because they often dissolve during baking.
- Bake these in a pan lined with foil or parchment paper for easy removal. They’re super gooey!
- Be sure to allow them to cool completely before slicing.
- Storage: Store in an airtight container or covered with plastic wrap. If you are going to put them in the freezer, slice them before freezing so they are easy to grab and defrost when the craving hits.
FAQs
Can you freeze these gooey bars?
Yes you can! Freeze them in an airtight container for up to 3 months.
Funfetti Gooey Bars Recipe
These Funfetti Gooey Bars are the best cake mix cookie bars ever! Made with a cake mix and a few simple ingredients, they are gooey to the max!
Prep Time 15 minutes
Cook Time 30 minutes
Total Time 45 minutes
Ingredients
- 1 box (approx 15 ounces) yellow cake mix
- ½ cup (113g) unsalted butter, softened

Instructions
- Preheat oven to 350°F. Line a 9×9” pan with foil and spray liberally with cooking spray.
- Add cake mix, butter, and egg to the bowl of an electric mixer fitted with a paddle attachment. (You can also use a hand mixer.) Mix until a thick dough forms. This will take a long time, especially if you're using a hand mixer. Just keep mixing! Add sprinkles and stir until incorporated.
- Press about ½-⅔ of the dough into the bottom of the prepared pan.Pour sweetened condensed milk over the top of the dough, leaving a thin border around the edges. Sprinkle with white chocolate chips. Separate remaining dough into small balls and evenly space over the top of the bars. Press down to flatten. Try to seal the edges as much as possible.

Recipe Notes
- Use higher quality jimmies so they don’t melt – any color can be used. Do not use non-pareils.
- Wait until they’re cool to cut.
- I recommend baking in a metal pan with foil or parchment paper for easy removal.

So you can use a hand mixer?
Made my own version of these bars due to my mad love of rainbow chip cake mix and my complete inability to use a half of a can of sweetened condensed milk. Two rainbow chip cake mixes, two eggs, half cup each butter and plain yogut mixed to a thick batter. Two thirds spread in a parchment lined and sprayed 9 by 13 pan. Topped by two cups white chips and of course a whole can of sweetened condensed milk. Drop rest of batter by spoonfuls over top and bake at 350 for 30 minutes. Cool.
LOVE IT! I know, I hate using half the can – but I’m usually making 100 other things, so it’s easy to use it. Using the whole can for a 9×13 is perfect!!
These look so yummy!
I want them make them tonight. Are they ok to ship priority mail?
I’ve made these twice so far, and I have to tell you that my husband LOVES them. “I’d do anything to get more” were his words to describe them. Ha! Thanks for the recipe!
I’m so glad Anne!!! Thanks for letting me know!
I made a variation of these with red velvet cake mix (with cubes of cream cheese mixed in after it’s blended) and white chocolate chips. O-M-G, it was almost better than S-E-X! Thanks for the recipe!
Just made these for the first and probably last time. They did not come out like bars at all. More like blobs. I followed the recipe to a T to no avail. I even cooked them 5 minutes longer. The white chips haven’t even melted….
Hi Barbara, I’m sorry about that. The white chips aren’t supposed to melt (you can see them in the bar in the picture). Kind of like a chocolate chip cookie? The pan of bars when removed from the oven is quite gooey, and needs time to set (hence the chilling). Once they’re chilled and cut, they taste amazing, even if they aren’t beautiful!
I made these for my moms birthday a few weeks ago and I’m repeating them today for Mother’s Day! We LOVE them and now that I know the base recipe, there’s seriously SO many options! I have an 8×8 pan and I cooked them in that last time and they still turned out great! Just a little fatter 🙂
I love them fat as can be! 🙂 I’m so glad you liked them!!
I stumbled upon your site and just had I add these to my list of desserts to make for Mother’s Day this year (even though it is quite full). Much of my family has celiac disease and this was so simple to adjust to be gluten free! Thank you so much! They just came out of the oven and I cannot wait to try them! Have you ever put them in the freezer to cool quicker? I’m not sure I can wait until Sunday to eat these!
I’m so glad they work gluten free! That’s one of the thing I love about mixes! Freezer, go for it. I have used it for blast cooling before, not with these, but with other things. 🙂
I made these for my office. One of my coworkers proclaimed that he wanted to marry me so I could bake these for him every day.
LOL! That’s so great, thank you. I’m glad everyone enjoyed them!
Ooooh you had me at gooey. Looks amazing 🙂
