Ingredients You’ll Need
Getting started with this Marshmallow Rice Krispie Treats Recipe is a breeze because the ingredients are both simple and purposeful. Each component adds a unique touch to the final treat, from the butter’s richness to the marshmallows’ melt-in-your-mouth sweetness and the crispy cereal’s signature crunch.
- Rice Krispies cereal: 6 cups of these light, crispy cereal pieces form the base and give the treats their irresistible crunch.
- Mini marshmallows or marshmallow fluff: 10 oz of mini marshmallows or 4 cups of fluff provide that sticky, sweet binder that holds everything together.
- Unsalted butter: 3 tablespoons add richness and help melt the marshmallows uniformly without overpowering the treats.
- Vanilla extract (optional): A 1/4 teaspoon enhances the sweetness and adds a subtle warmth to the flavor profile.
- Pinch of salt (optional): Just a touch balances the sweetness and intensifies the overall flavor for a more rounded taste.
How to Make Marshmallow Rice Krispie Treats Recipe
Step 1: Prepare Your Dish
Lightly grease a 9×13-inch baking dish with butter or non-stick spray to ensure the treats won’t stick. Having the dish ready makes it easier to transfer the sticky mixture without losing any of the deliciousness.
Step 2: Melt the Butter
Place 3 tablespoons of unsalted butter in a large pot over low heat and stir continuously. This gentle melting process prevents burning and helps achieve a smooth, creamy base for the marshmallows.
Step 3: Add the Marshmallows
Once the butter is fully melted, add your mini marshmallows or marshmallow fluff directly to the pot. Stir carefully over low heat until the marshmallows have completely melted into a glossy, sticky mixture that will coat the cereal evenly.
Step 4: Add Flavor (Optional)
For an extra layer of flavor, stir in a 1/4 teaspoon of vanilla extract and a pinch of salt. These additions might seem small, but they elevate the taste, making the treats even more irresistible.
Step 5: Mix in the Cereal
Quickly pour 6 cups of Rice Krispies cereal into the melted marshmallow mixture. Using a spatula, gently fold the cereal in until every crisp is coated in that sweet, gooey goodness, but be careful not to overmix or crush the cereal.
Step 6: Press Into the Dish
Transfer the mixture to your prepared baking dish. Use a spatula or wax paper to press it down evenly, applying light pressure to keep the treats light and airy rather than dense. This step sets the shape and texture for perfect squares.
Step 7: Let Them Cool
Allow the treats to cool for at least 30 minutes at room temperature. This resting time lets them firm up just enough so you can cut them into squares or rectangles without crumbling.
How to Serve Marshmallow Rice Krispie Treats Recipe

Garnishes
While these treats are delicious on their own, try sprinkling some colorful sprinkles, mini chocolate chips, or even a drizzle of melted chocolate for an extra-special touch. These garnishes add visual appeal and can personalize the treats for any occasion.
Side Dishes
Marshmallow Rice Krispie Treats pair wonderfully with classic cold milk, a cup of hot cocoa, or even fruity smoothies. These beverages complement the sweetness and provide a refreshing balance to the chewy texture.
Creative Ways to Present
Try cutting the treats into fun shapes using cookie cutters for themed parties or celebrations. Stack them with layers of fresh fruit or even sandwich a smear of peanut butter between two squares for a playful twist that surprises the palate.
Make Ahead and Storage
Storing Leftovers
Keep your Marshmallow Rice Krispie Treats fresh by storing them in an airtight container at room temperature. They should stay soft and chewy for up to three days, making them a perfect make-ahead snack for busy days.
Freezing
You can freeze these treats by wrapping individual squares tightly in plastic wrap and then placing them in a freezer-safe bag. They maintain their quality for up to six weeks and thaw quickly at room temperature, making them a convenient treat to enjoy anytime.
Reheating
While these treats are best enjoyed at room temperature, a quick 5-10 second zap in the microwave (wrapped loosely to avoid drying) can bring back some of that fresh, melty softness if they’ve stiffened in storage.
FAQs
Can I use regular-size marshmallows instead of mini ones?
Absolutely! Regular marshmallows will work just fine, though mini marshmallows tend to melt a bit faster and blend more evenly with the cereal.
Is it possible to make these treats gluten-free?
Yes, as long as you use gluten-free puffed rice cereal like Rice Krispies Gluten-Free, your treats will be safe for those avoiding gluten.
How do I prevent my treats from turning hard?
Be careful not to overcook the marshmallows or press the mixture too firmly when setting it in the pan. Also, store them properly in an airtight container to maintain softness.
Can I add other mix-ins to this recipe?
Feel free to get creative by tossing in chocolate chips, M&M’s, nuts, or dried fruit right before you press the mixture into the pan for personalized flavor and texture.
What if I don’t have vanilla extract?
No worries, the vanilla extract is optional and just enhances the flavor. The treats will still be delicious without it!
