Here’s a fun and colorful treat the kids will love—Funfetti Marshmallow Cereal Bars! Packed with Cheerios, Lucky Charms, and loads of marshmallow goodness, these bars are a blast to make and even more fun to eat. Perfect for snack time, lunchboxes, or just because!
I recently made some S’mores Overnight Oats and had some marshmallow fluff left over, so I knew I had to put it to good use. That’s how these Funfetti Marshmallow Cereal Bars came to be! They’re packed with crispy cereal and rainbow sprinkles, and they’re everything you want in a sweet treat—thick, soft, chewy, with just the right touch of vanilla. Perfect as a dessert or snack, and so fun to make!
I love making these for my boy—he gets so excited to help with the sprinkles! We usually mix in Cheerios + Lucky Charms for a fun twist on the classic 'Rice Krispie' treats. They come out so sweet, gooey, and tasty—perfect for sharing (or keeping all to ourselves. Haha). If you’re as into turning cereal into treats as we are, you’ve got to try my Loaded Lucky Charms Cornflakes Sugar Cookies or Chocolate Chip Cheesecake with Lucky Charms next!

Line a pan with parchment or foil—don’t forget a quick spray if you’re not using non-stick. In a bowl, mix up your cereals, marshmallow fluff, vanilla + sprinkles, and a pinch of cinnamon.
It’s going to get sticky, so gloves might come in handy! Press the mix into your pan, top with extra sprinkles, and let it chill in the fridge for about 30 minutes. No oven needed!

Funfetti is a fun and colorful twist on desserts, packed with colorful sprinkles mixed right into the batter or in this case marshmallow fluff. You'll see it in cakes, cookies, cheesecakes, and now these bars! It gives sweet treats a festive, confetti-like look, making them perfect for any celebration!
Cutting these sticky, gooey bars can be a bit tricky, but here’s a tip: spray a sharp knife with non-stick spray or lightly coat it with a bit of oil before slicing. You can also run the knife under hot water, then dry it off before cutting—this will help glide through the marshmallowy goodness without sticking. Make sure to clean the knife between cuts for the best results!
Yes, you can definitely make Funfetti Marshmallow Cereal Bars ahead of time! They’re perfect for prepping in advance. Just prepare the bars, let them cool and set, then store them in an airtight container at room temperature. They’ll stay fresh and delicious for up to a week. If you prefer them a bit firmer, you can also refrigerate them.
Leftover cereal bars can be tightly sealed and stored in the fridge for up to 1 week. Just know that the longer they stay in the fridge, the harder they get due to moisture being removed during chilling.
Absolutely! Cheerios and Lucky Charms are favorites, but feel free to mix and match with any cereal you love.
They can be, as long as you use gluten-free cereals and sprinkles.

Definitely! You can get creative by adding chocolate chips, nuts, or dried fruit. Just be sure to adjust the marshmallow fluff to ensure everything sticks together.
To avoid sticking, wrap each bar individually in parchment paper or plastic wrap before packing them in a container. This way, they’ll stay fresh and easy to handle.
