A sweet funfetti cake batter fudge that’s made with cake mix and packed full of colorful sprinkles.  A great birthday cake alternative!

Welcome to another installment of a day in the life of a sprinkles addict.

I may be biased, but it’s not a bad addiction to have, though it is causing some tension in my marriage — Zach does not like sprinkles in his desserts, or at least not nearly as many as I do, and I may or may not be storing (literally) 30 pounds of sprinkles in our office.

It’s also making its way into my work life (I shook a sprinkle out of my scrub top in the hospital the other day — Idon’tevenknow), and I had to brush bright pink powder out of the crevice of my camera where I accidentally crushed a lone sprinkle.

I’ve presented to you plenty of sprinkle-stuffed desserts in the past — funfetti cookies, my FAVORITE funfetti cake, and even a recipe for homemade sprinkles, to name just a few, but I think this is the first time that I’ve worked sprinkles into fudge.

Today I have a simple, decadent, no candy thermometer required, cake batter fudge for you.

do use box-mix cake batter here (I’ve waffled in the past on my preference for making things solely from scratch and incorporating box-mix for the most authentic flavor), but for this recipe cake mix resulted in the easiest and best tasting fudge of all of my taste-trials. If you’re concerned about using “raw” cake batter mix, I recommend cooking the cake mix in the oven for several minutes before using, just as I do with the flour in my cookie dough bites recipe.

I love making condensed milk fudge recipes (like my easy fudge recipe and hot chocolate fudge!) because of their simplicity — it’s just a matter of combining the ingredients on the stovetop and melting them together for sweet confection perfection.

This funfetti-packed cake batter fudge is very creamy, very sweet (cut it into small pieces!), and a little more than irresistible.

While I mentioned that Zach doesn’t like biting into sprinkles, I love the subtle texture that they make — it keeps things… interesting, fun, and (very) colorful. It’s also what I love about my Funfetti cupcakes.

You can use regular sprinkles or nonpareils, or a mix of both (which is what I did here).  The nonpareils give a little more of a crunch (I don’t want to say “gritty” because that sounds bad and it’s really a lovely texture, but I think that will give you a good idea of the taste), while the sprinkles are softer and less obvious.

Ingredients

  • 14 ounces (397 g) sweetened condensed milk, Make sure you are not using evaporated milk. Only condensed milk will work with this recipe.
  • 2 cups (340 g) Ghirardelli white chocolate chips, I only recommend Ghirardelli chocolate chips for this fudge. I have had no problems with this brand whereas people have not had their fudge set up properly with other chips.
  • 2 Tablespoons salted butter
  • ¼ cup (40 g) white or "funfetti" cake mix , not prepared -- just use the powdered mix straight out of the box. I use Pillsbury.
  • 1 ½ teaspoon vanilla extract
  • 2 Tablespoons colored sprinkles or a mix of sprinkles and nonpareils, + additional to sprinkle on top, if desired

Instructions 

  • Line an 8x8 pan with parchment paper. Set aside.
  • Combine condensed milk, chocolate chips, and butter in a medium-sized saucepan over medium heat.  Stir frequently until butter and chocolate chips are completely melted and mixture is well-combined.
    14 ounces (397 g) sweetened condensed milk, 2 cups (340 g) Ghirardelli white chocolate chips, 2 Tablespoons salted butter
  • Reduce heat to low, and add cake mix and vanilla extract. 
    ¼ cup (40 g) white or "funfetti" cake mix, 1 ½ teaspoon vanilla extract
  • Stir well, until cake mix is completely absorbed.
  • Remove from heat and stir in 2 Tablespoons sprinkles/nonpareils.  Immediately pour into prepared pan, use a spatula to gently smooth the surface. 
    2 Tablespoons colored sprinkles or a mix of sprinkles and nonpareils
  • Decorate with additional sprinkles, if desired.  Allow to cool to room temperature. If desired, chill in the refrigerator until completely firm before cutting and serving. It usually only takes several hours for my fudge to become completely firm, but since some people have had issues with their fudge setting (see note or see video) I recommend allowing it to chill overnight for best results.

Notes

Some people have commented that they have had problems with this fudge setting. I have re-tested this recipe nearly 2 dozen times now and have had friends do so in their own kitchen and have not been able to replicate this issue. One friend noted that her fudge was still soft after two hours so instead of recommending that you refrigerate for two hours or until firm (which I originally suggested in 2017) I now recommend chilling overnight. I have updated the ingredient list to include my preferred brand of chocolate chips and the cake mix and have added a photo of the ingredients I use in the post above. I've also included a step-by-step video in this recipe showing you exactly how I make this cake batter fudge in my own kitchen that I hope will be helpful!

    This recipe turned out perfectly. Thank you for all your detailed instructions.
    If I don’t want to make more fudge, is there another recipe I could use for the remaining cake mix?

      Thank you so much for trying my recipe, Lucky! I’m so glad you enjoyed the fudge! My funfetti cheesecake bars use cake mix. 🙂
