Extra Thick Lucky Charms Marshmallow Treats are a taste of childhood! I can’t stand a wimpy marshmallow treat, so these are a full 2 inches thick, gooey, and sweet. Wrap them up in plastic wrap to give away and watch people’s eyes light up!
What is it about marshmallow treats that make me so nostalgic? We didn’t have them often as kids, so maybe that’s why they seem special. I took the classic marshmallow treat and fancied it up for St. Patrick’s Day, using Lucky Charms for the base and making them EXTRA thick.
I started with one whole (10.5 oz) box of Lucky Charms, which is about 9 cups. I found a St. Patrick’s Day edition of Lucky Charms at my local grocery store, but the regular version works great, too. I fished out a few of the marshmallows to save for the top—this is key for presentation!
The rest of the recipe is classic: a little butter, a bunch of marshmallows, and I added a pinch of salt to balance the sweetness.
You could use either large or miniature marshmallows here. The recipe calls for 1½ bags of marshmallows, which I admit is kind of annoying. I know that I don’t want half a bag of marshmallows lying around, so here are a few ideas:
1. Add them to trail mix
2. Use them to top hot cocoa
3. Make a double batch of these Lucky Charms Treats (just double each of the ingredients and you’ll use 3 bags of marshmallows)
On the plus side, the recipe uses an entire box of Lucky Charms, so you won’t have extra cereal taking up space in your pantry. 🙂
The fact that these Lucky Charms Marshmallow Treats are extra thick make them even more special. I made them in an 8×8 inch square pan which I lined with parchment paper first (this makes them easy to get remove and slice). The treats will come up to the very top of the pan, which is about 2 inches high.
I recommend using a large pot or bowl to make these. I went for the route of less clean-up and made them in a 5–6 quart dutch oven. I heated the butter and marshmallows in the dutch oven, stirred in the cereal, and transferred it to the 8×8 inch square pan.
A quick tip on transferring the treats to the pan: use a small plastic bag sprayed with cooking spray to spread them out. The treats won’t stick to your hand or a spatula, and you’ll be able to work quickly to flatten the mixture before it cools.
The recipe for Lucky Charms Marshmallow Treats makes 9 large (3×3 inch) squares. These are generous portions, so you could definitely slice them smaller since they are so thick.
I wrapped some individually in plastic wrap and sent them to work with my husband to share with his co-workers.
Extra Thick Lucky Charms Marshmallow Treats
- 4 tablespoons butter
- Pinch of salt
- 1½ 10 oz bags marshmallows (about 60 large marshmallows or 6 cups of miniature marshmallows)
- 9 cups Lucky Charms cereal exactly one 10.5 oz box
- Line an 8x8 inch baking dish with parchment paper, or spray with nonstick cooking spray.
- Pick out ¼ cup of the marshmallows from the Lucky Charms; set aside.
- Melt the butter and salt in a large saucepan or pot over medium heat. Add the marshmallows and stir until the marshmallows have completely melted.
- Remove from the heat and let sit for 1 minute. Since Lucky Charms have marshmallows, this will prevent the marshmallows in the cereal from melting. Meanwhile, spray a small plastic resealable bag with cooking spray on one side.
- Pour in the Lucky Charms and stir to combine. Pour the mixture into the prepared baking dish. Place your hand inside the plastic bag and push the cereal down into the dish in an even layer. The cooking spray prevents the mixture from sticking to the bag.
- Place the reserved Lucky Charms marshmallows on top and let cool for at least 30 minutes.
- Lift the parchment paper out of the pan, place on a cutting board, and use a sharp knife to slice the Lucky Charms Treats into squares.
- If not serving immediately, wrap the squares tightly in plastic wrap. Serve within 2 days.

- Note: I know, I know—1½ bags of marshmallows? Who wants half a bag of marshmallows sitting around? Use them for hot cocoa, put into trail mix, or make a double batch of these gooey treats and it’ll require 3 bags. The recipe does use up a whole box of Lucky Charms so you won’t have those laying around. 🙂
