Rice Krispie treats are a classic old-style snack that has been around for years. This particular spin, Caramel Stuffed Rice Krispie Treats are packed with marshmallows and coated with caramel. They are super easy to make and are loved by everyone! Personally, I love caramel and marshmallows, paired with rice krispies, they are a perfect marriage.
How to make Caramel Stuffed Rice Krispie Treats
- Grease a 9X13 glass pan, set aside. If using something other than glass, press parchment paper on bottom, lightly grease and finely crush up Rice Krispie cereal to line the bottom with.
- For the Caramel Filling – In a medium saucepan on medium heat, heat butter and sweetened condensed milk. Unwrap caramel pieces and add. Stir frequently until combined then turn heat down to low.
- For the Krispie Layer (two separate layers will be prepared) – In a large saucepan on medium heat, melt 6 tablespoons butter. Once melted, stir in 4 cups mini marshmallows and whip batter until smooth. Combine 5 cups Rice Krispie cereal and mix well until evenly coated.
- Next, using piece of wax paper lightly greased, press Krispie layer down evenly into pan. Pour caramel filling over the top and spread evenly. Press about 2 1/2 cups mini marshmallows into caramel layer.
- Repeat Rice Krispie layer with remaining ingredients. Heat 6 tablespoons butter and 4 cups mini marshmallows. Add 5 cups cereal and stir to combine. Press layer on top of marshmallow/caramel layer using a piece of lightly greased wax paper. Refrigerate at least 2 hours to set up.
Caramel Stuffed Rice Krispie Treats Ingredients
Caramel Filling
- 1 – 14oz can of sweet and condensed milk
- 14oz of caramel pieces
- 1/2 cup of butter
Rice Krispie Layer
- 12 tbsp butter
- 10 cups of rice krispie cereal
- 10 1/2 cups of mini marshmallows

Caramel Stuffed Rice Krispie Treats Variations
Peanut butter: Either in a drizzle or major part of the rice krispie peanut butter can change the flavor and consistency of this snack.
Chocolate: This could also be used for a drizzle or coating. I have seen people incorporate different milk chocolate bars or dark chocolate to give this snack a new flavor.
Crunch Bar: Not only would this elevate the taste with the chocolate, but it would also add a nice crunch to this treat.
Snickers: I have toyed with the idea of adding some mini snickers to the interior of this recipe. It would definitely add another layer of savory to this recipe.
Reeses: As with the snickers, adding either reeses pieces or even reeses peanut butter cups to this recipe would be an extremely delicious variation.
Peanuts: If I were going to add peanuts, I would add them as a crumble topping. You would also want to carefully consider which type of peanuts as some would add salt. Some people love sweet and salty!
Pistachios: This would also be something I could imagine adding by crumbling pistachios into a topping. Same thing with the peanuts however, I might be a little concerned about salt content.
Tips and other notes
Use a piece of wax paper/parchment paper/foil generously greased to press down Rice Krispie layer evenly into pan.
*If not using a glass pan, place parchment paper into pan. Lightly grease with butter. Finely crush Rice Krispie Cereal and spread evenly over the bottom. This will prevent it from sticking.
Storing Options and Shelf Life
These rice krispies can be stored on a plate with clingwrap or some kind of airtight storage. They can last anywhere up to 5 days. I have heard of people freezing them, but I do not advise doing that. Ice crystals would form and ruin the treat as you defrost.

These are amazing! For a slightly more grownup version, I browned the butter, added sea salt to the caramel layer and omitted the mini marshmallow layer. Delish!
I’d love some of these right now! Thanks, Nicole!
Hi Jessica! So I’m curious why the lower layer looks dipped? In your picture, are those outside edges that the caramel ran down?
Hi Jodi, some caramel does drip down. However, I did dip the ends in leftover caramel that I had.
