Super Sour Kool-Aid Grapes (Only 2 Ingredients!)

I don’t know about you, but I love sour candy. If I’m on a long road trip and I need a snack, 9 out of 10 times I’m going for the sour gummy worms. But as my dad-bod goes from super-hot to something else, I realize I have to keep my sweet tooth in check.

So when I discovered the deliciousness that are Kool-Aid grapes, I had to try them out. There are a couple of variations of this recipe. You can use the pre-sweetened, “just add water” Kool-Aid or a packet of flavored and sweetened Jello powder. You can even use sugar-free Jello and make a Weight Watchers-friendly recipe.

So if you’re a fan of sweet and sour, but not intensely sour, this recipe can easily be adjusted. For me though. I’m going with sour. And I love that I get to bring back a blast from my childhood: Kool-Aid.


  • 2-3 lbs grapes (You can use whatever color grapes you want, but green grapes will show the most coloring from the Kool-Aid.)
  • 2-3 packets of Kool-Aid mix (If you want your grapes super sour with no added sugar, get the small 0.14 oz packages. If you want something sweeter, use the “just add water” Kool-Aid that has sugar.)


  1. Allow the grapes to sit in the freezer for about an hour to start to freeze (the grapes will be easier to destem when they’re frozen.)

  1. Destem and wash the grapes. Shake some of the water off, but don’t let them completely dry. A little water will help the Kool-Aid stick, but too much will make a gloppy mess.

  1. If you want to have different flavored Kool-Aid (which I like. This way I can find out what’s my favorite), separate the grapes into different zip-top bags. If you want one flavor, put all the grapes in one bag. I decided to go with lemon, cherry, and grape (yes, I flavored my grapes with grape flavoring. It was awesome).

  1. Line a large sheet pan with a piece of parchment, wax paper, or a Silpat. Pour the coated grapes onto the baking sheet and freeze overnight.

Warning: The Kool-Aid coating will stain! Do not snack on these grapes on the couch or eat over any furniture you care about. Prepare to have stained fingers. It’s a small thing to pay for something so delicious!

Final Thoughts

Just a few things from my experience. Be prepared to get stained fingers, especially with darker-colored Kool-Aid mixes (the purple in the grape flavor was especially dark). Do not eat these on the couch or any furniture you care about. And you can bet I don’t trust my kids to eat these anywhere except at the kitchen table. With a roll of paper towels. Maybe even a bib.

My other advice is after you scoop some out of the freezer to snack on, let them sit on the counter for about 5-10 minutes. This will help take some of the intense cold off. A little of the slightly melted grape juice will help take down some of the intense bite of the citric acid in the Kool-Aid coating.

All the flavors were great. I loved going back and forth between them all. The lemon flavor was definitely the most intense. I liked it, but I definitely could not only eat the lemon-coated grapes.

If you want to store the grapes, put them in a zip-top bag and leave them in the freezer. This is a great treat to randomly snack on when you’re bored looking around in the refrigerator. No added sugar, and a little goes a long way!
