I never thought I’d say this, but I might love these Lucky Charms Rice Krispie Treats even more than classic Rice Krispie treats! They’re gooey, have an extra crunch, and the colorful marshmallows add so much charm!
The perfect St. Patrick’s Day treat, especially if you love festive desserts like my Lucky Charms Cupcakes.

Pin ItThis started as a fun St. Patrick’s Day idea, but the second I browned the butter and folded in the Lucky Charms, I knew these were going to be dangerous. They’re rich, nostalgic, and loaded with those marshmallow bites everyone secretly eats first… you know you do! If you’re planning a St. Patrick’s Day spread, these pair perfectly with treats like my Baileys Dipped S’mores.
When I tell you my kids (and husband!) went crazy over these, I mean it. They kept sneaking pieces off the counter while they were setting, and by the end of the day, the pan was basically gone. But I did take these pictures, thank goodness!

If you already love my strawberry Rice Krispie treats, this is a fun, festive twist you’ll want to try next.
Ingredients

Lucky Charms cereal: Measure it out with a 1-cup measuring cup so the ratio stays just right. You want plenty of cereal without losing that gooey marshmallow texture.
Unsalted butter: Browning the butter is what makes these special. It adds depth and balances the sweetness perfectly, just like I do in my Strawberry Rice Krispie Treats.
Marshmallows: These melt into the browned butter to create the soft, gooey base that makes these irresistible. Kind of like making an easy marshmallow fluff, yum!
How to Make Lucky Charms Rice Krispie Treats




- Measure out 7 cups of Lucky Charms cereal using a 1-cup measuring cup and set aside.
- In a large pot, melt the butter over medium heat. Continue cooking until the butter turns golden brown and smells nutty.
- Lower the heat, add the marshmallows and salt, and stir until completely melted and smooth.
- Turn off the heat and add the Lucky Charms cereal. Stir until everything is evenly coated.
- Press the mixture into an 8×8 ceramic pan. I don’t butter the pan or use parchment underneath because there’s plenty of butter in the recipe and they release cleanly.
- Place parchment paper on top and gently press the treats down.
- Let them sit for about 1 hour before cutting.
Eden’s Recipe Tips
These are best the day they’re made, but still delicious the next day
Browning the butter is worth the extra minute and adds so much flavor
Use a large pot so mixing is quick and easy
I always use parchment paper to press the gooey marshmallow mixture into the pan so it doesn’t stick to my hands and presses evenly.
A ceramic pan works great and doesn’t need greasing
You can dip these in white chocolate instead of regular chocolate if you want something extra fun and festive
