Cake Batter Popcorn Gooey-ness

We have movie night every Friday as a family, and we love to have some yummy treat to go with it.

This past week, we made Birthday Cake Popcorn, and it was delicious!! It is gooey and had sprinkles and was a hit with all of the kids in the family.

It was also very simple to make, so you better believe we will be making this again.

Ingredients for birthday popcorn

Tips + Tricks

For making birthday cake popcorn:

  • I add dry cake mix to the mixture, not prepared.
  • This popcorn is sticky and can be a little messy (but so worth it) just keep this in mind when serving it.
  • Use a lightly salted, plain or a lightly buttered popcorn for this recipe. I would avoid using a really buttered popcorn.

To make into popcorn balls: After the popcorn is completely coated, lightly grease your hands or get them wet and pack the popcorn into ball shapes. You will want to re-wet or re-grease (lightly) between each popcorn ball. This will help the popcorn from sticking.

Popcorn FAQ

Can this be made in advance? This popcorn is definitely best eaten soon after it is made. If you want to make it in advance I would suggest making it as close to when it will be eaten as possible but no more than 2 days ahead of time. After it is made, store it in an airtight container until ready to serve. You can also make them into individual servings and store in ziplock bags, just try to squeeze as much air out as you can. 

How to store? Store leftovers in an airtight container at room temperature for up to 2 days. 

How to make for a crowd? If you are wanting to make this popcorn for a crowd and you’re worried about the sticky mess, just divide the popcorn into individual servings or have the guests scoop the popcorn out with a large serving spoon or measuring cup.

    1. It is the dry mix, that you add to the melted marshmallows and butter, then you’ll add the cake mix, vanilla, and milk. It is the tastiest popcorn ever!! Hope you like it!

  1. Vanilla extract or vanilla icing? I have an upcoming 4th of July / birthday party coming up & want to make this with red, white, & blue star shaped sprinkes for the kiddos (if it makes it to the table 😉

  2. This looks soooo tasty! We are heading out on a family RV trip and I was thinking about bringing this. Is it something you have to eat fresh, or will it harden into an inedible glob if I make and bag it in advance?


  3. This looks so yummy! Have you made it a day or so early? How early could I make it and store it for later use? Does it get hard when it cools? Thanks so much!

  4. Hey! I have two questions. Do you think I would be able to use a different cake mix (like chocolate for example. Have you tried that?) And how messy is this? I was thinking for a game night but I don’t want people to be sticking to the pieces. Thanks in advance! 🙂

      1. Hi want to make this for my daughter sleepover, but I will like to prep and make it a day in advance and put it in clear favor bags tied up. Would it be fine.

  5. Hi! This looks great. I’ve been considering making it as an end of the year treat for my students. Do you have an estimate of how many “servings” this would yield?


    1. It just depends on how much you are giving them. You’ll probably want to double/triple the recipe for sure. I wish I knew an exact amount, I’m sorry. They will love it, though 🙂

  6. Does this stay clumped together (more like popcorn balls) or separate more? I’m trying to decide if I should make this for a 8 adult movie party or if it would be too awkward to self serve and share.
    Either way I’ll be making this soon. Looks awesome. ????

    I tried out your birthday cake popcorn for my son’s birthday party, and it was a hit! I’m going to post a photo of it on my brand new website (it’s only got a few posts so far). I’ll make sure to credit you with a link so they can check out your awesomeness (they=my future fans).

    I actually used light butter. It was recommended I not do it on the actual Rice Krispy site, but I learned a trick….if you do the melting part super, duper slowly, it will turn out just fine with light butter.

    I’ll be using real butter next time though! I’m all finished with my light and fat free phase!

  8. This looks really fun. How long does the popcorn last. I was thinking of doing this for a graduation party and making it ahead of time. So, was wondering if I could make it a couple of days ahead.

    Thank you,
