Hey there! Before you scroll, there’s lot’s of important stuff in the post!…including the FAQ section, which may answer any questions you might have about this recipe. Enjoy!

I love these cake mix bars because not only are they so good (and addicting), but they’re so easy to make and don’t require a lot of ingredients.

If you have to put together a quick treat, then these are definitely the way to go and the possible flavor combinations are endless.

Let’s Talk About Some of The Ingredients in These Bars:

Cake mix: You’ll be using either a vanilla, french vanilla or white cake mix for this. You could probably use any flavor, but if you want it to be funfetti cake bars, then you’ll want to use a light colored cake mix, so the fun colors will actually show up.

Melted Butter: I used unsalted butter for this recipe. Read the tips and faq section below to see my notes about that.

Vanilla Extract: This just bumps up the flavor a bit.

Mini semi-sweet chocolate chips: I like using the mini chips here because they don’t all sink to the bottom and I think the size of them is just perfect for these bars.

Rainbow jimmies: You’ll use these to get the funfetti look. Jimmies seem to work better than the small round rainbow sprinkles as those seem to bleed color quite a bit. (Watch the video below in the recipe card to see a closeup of the sprinkles I used.)

Mixing Method for These Cake Bars:

Oh my goodness the mixing method for these things are insanely easy. You’ll add all the ingredients in a bowl (except for the chocolate chips and sprinkles) and mix together with an electric mixer.

Once that’s well mixed, you’ll add in the chocolate chips and sprinkles and mix those in by hand.

Tips & FAQs for the Funfetti Chocolate Chip Cake Mix Bars:

Do I have to use vanilla cake mix?

Vanilla cake, French vanilla cake, or White cake mix is best here so that the funfetti colors can still be seen once baked. You can of course use any flavor of cake mix and it will taste just fine though.

What type of butter should I use?

Generally when baking, you’ll use unsalted butter. If you can’t find that, salted butter will work okay. I have not tried this recipe using margarine, so I’m not sure what the outcome would be.

Why do I need to use the rainbow jimmies? Why can’t I use the small round sprinkles?

You can use the round sprinkles, but I’ve found that the color bleeds more if you use those.

When baking these, once you reach 20-25 minutes, take them out of the oven.

They will still be a little soft, but that’s okay. If you bake them too long, they will end up hard and crunchy when they firm up later.

Let these bars cool completely before cutting.

These bars need to come to room temperature before you cut them, or they won’t be firm enough and you’ll have a mess on your hands. You don’t need to chill them in the fridge though…just set them out on a rack to cool at room temperature.

Ok let’s get to the recipe!

***I write recipes using volume (cups) measurements because here in the U.S., this is what people are used to seeing and using. For weight in metric measurements, click the ‘metric’ button under the ingredients in the recipe card. The weights are converted by a program, not me, and it’s a best guess. Please note that because I develop recipes using ‘cups’ I can’t guarantee that weighing the ingredients will produce the exact same results.

  • 2 large eggs
  • ½ cup melted unsalted butter

Instructions

  • Preheat the oven to 350 degrees. Spray a 13×9 inch glass pan very well with a non-stick spray.
  • In a large mixing bowl, add the cake mix, eggs, melted butter and vanilla. Mix well with an electric mixer.
  • Add in the mini chocolate chips and sprinkles and mix well with spoon or rubber spatula. Batter will be very thick.
  • Spread batter into prepared pan. Use a rubber spatula or spoon to press the batter evenly in the pan. (It helps to spray your spoon or spatula with non-stick spray, so it doesn't stick to the batter.)
  • Bake at 350 degrees for approximately 20-25 minutes until the edges are golden brown.
  • Cool the bars completely in the pan, on a cooling rack at room temperature. Make sure to let the bars cool completely before cutting, or you'll have a mess.
