Cornflake Marshmallow Treats Ingredients
My cornflake marshmallow treats recipe is easy because it has just a few, simple ingredients:
Cornflakes – 6 cups. If you buy a box that’s at least 9 oz, you should have enough.
Marshmallows – 14 oz. I started off with just 10 oz, but as expected, I ended up adding more. I used miniature marshmallows since they tend to melt better.
Butter – 1 stick, unsalted
Optionally, you can also add:
Salt – 1/8 teaspoon. If using unsalted butter, I recommend adding a pinch of salt.
Extra Salt – 1/8 to 1/4 teaspoon. An extra sprinkling of salt once the treats are cut into squares will help bring out the flavor.
Vanilla – 1 teaspoon. I didn’t add any vanilla since marshmallow usually have vanilla flavoring.
Tools:
Before starting this recipe, make sure you have:
Large Pot – You’re going to need enough room to stir all the ingredients together, so make sure your pot is big enough.
Wooden Spoon – A large wooden spoon or spatula to stir the cornflakes and marshmallows.
8×8 Casserole Dish – Pour the hot corn flakes and marshmallows into a casserole dish to harden.
Cooking Spray – These treats can be sticky, so spraying your hand with non-stick spray makes it much easier to handle these cornflake treats when they’re still warm.
How to Make Cornflake Marshmallow Treats
Learning how to make cornflake marshmallow treats is easy. You just have to follow a few, simple steps:
Gather the Ingredients
It’s important to gather the ingredients before starting cornflakes marshmallow treats recipe. This recipe moves very quickly, so you want to make sure you have everything you need ready to go.
Butter the 8×8 Dish
Rub butter in the 8×8 casserole dish in which you’re going to let the treats harden. You could also use non-stick spray to coat the dish. Like I said, this recipe moves quickly, so I would grease the dish before starting.
Melt the Butter
The first step in the recipe is melting the butter. Put the butter into a large pot on the stove and melt the butter on medium heat, stirring constantly.
Add the Marshmallows
Once the butter is melted, add the marshmallows. At first I only added 10 oz of marshmallows because I wasn’t sure how many ounces I was going to need, but I ended up adding 4 more oz later for a total of 14 oz. However, I recommend adding all 14 oz at the beginning.
Add the Cornflakes in Stages
When you see that the marshmallows are fully melted, start adding the cornflakes in stages. I think I added about 1/3 of the cereal at a time, but looking back, I think that adding 1/4 of the cornflakes at a time would have made it easier to mix in the cereal..
Turn Off The Heat and Add the Vanilla (If Using)
Once all the cornflakes are completely coated in the melted marshmallows and butter, turn off the heat. If you want to add vanilla extract, now is the time to add it. I don’t recommend adding the vanilla extract at the beginning because the heat might burn off the vanilla.
Pour the Cornflakes Treats into the 8×8 Dish
Now it’s time to pour the hot cornflakes, marshmallows, and butter into an 8×8 dish to harden. Although the mixture will be hot at this point, it will start to set quickly: that’s why you should gather the ingredients and prepare the mold before you turn on the heat.
Spray Your Hand with Non-Stick Spray
These soon-to-be treats are extremely sticky while they’re still hot, so spraying your hand with non-stick spray or coating it in butter will help tremendously when you pat them down flat into the 8×8 dish.
Pat Down the Warm Treats Into the 8×8 Dish
Although the corn flakes treats will still be hot, using your hand to pat them down flat is easier than using a wooden spoon or large spatula. So, use caution to them down into the 8×8 dish so you can later cut them into squares or bars.
Let the Cornflake Marshmallow Treats Harden
Corn flakes marshmallow treats hold their shape better if you wait until they’re fully cooled to cut, but I think they taste better warm, so I only waited about 15 minutes.
However, if you want your treats to hold their shape perfectly, I would wait at least 30 minutes, if not a full hour to cut them. If you make ball-like cookies, I think they’d be almost totally cooled after 30 minutes.
Cut The Treats
Once the cornflake treats have set enough for you, it’s time to cut them into pieces.
Sprinkle With Extra Salt (Optional)
Even though an extra sprinkle of 1/8 to 1/4 salt on these treats is optional, I highly recommend it: I thought it really helped to bring out the flavor.
Serve
Enjoy these easy, no-bake cornflake marshmallow treats!
Cornflake Marshmallow Treats FAQ’s
How Many Treats Does This Recipe Make?
Although it depends on how large you want the portions to be, I would say that this recipe makes 9 large servings, 12-16 servings that are just a few bites.
Should Cornflake Marshmallow Treats Be Served Warm, Cold, or Room Temperature?
This is personal preference. In my opinion, these cornflake treats, rice krispie treats, and other marshmallow treats taste better and are crisper while still warm.
How To Store Cornflake Treats
Store your treats in the refrigerator in a closed container. If you want to eat them warm, take the treats out of the refrigerator 30-60 minutes before you want to eat them.
How Long Do Cornflake Marshmallow Treats Last?
2-3 days. Although some websites say that marshmallow treats will last up to a week, I think that as with many homemade desserts, cornflake treats will be past their peak after the 3-day mark. They should still be acceptable up to a week–just dried out and past their prime.
Can You Freeze Cornflake Marshmallow Treats?
Yes! To freeze corn flakes treats, simply cut them into individual portions, wrap them in plastic wrap, put them in a plastic bag, and then freeze. Your treats should stay good frozen for up to 3 months.
To thaw, simply take them out of the freezer and let them come to room temperature either in the refrigerator or on the counter. They will still be as crispy and crunchy as ever!
Do I Have To Use Miniature Marshmallows?
No, you don’t. As in other treats recipes, I used miniature marshmallows because they tend to melt easier and faster than large marshmallows. However, if you have large marshmallows, feel free to use them.
Cornflake Marshmallow Treats Recipe Variations
If you want to put a twist on this recipe, good ideas include:
Chocolate Treats – Although you could use chocolate corn flakes, adding cocoa powder and chocolate chips while melting the marshmallows would make these extra chocolatey.
Peanut Butter Treats – Adding some creamy peanut butter would make these extra delicious.
Cornflake Marshmallow Wreaths – Forming the treats into wreaths and adding green food coloring would make them perfect for Christmas and the holidays.
