Ingredients You'll Need

You only need a handful of simple pantry staples to make this M&M Rice Krispie Squares recipe. Each ingredient plays an important role in creating soft, chewy, perfectly balanced squares.

Butter - Butter adds richness and that classic homemade flavor. If you prefer, you can substitute coconut oil, but butter gives the best soft, chewy texture in traditional Rice Krispie squares.
Rice Krispie Cereal - Classic Rice Krispie cereal gives these squares their light, crispy texture. Make sure your cereal is fresh - stale cereal can make the bars taste flat and less crunchy.
Marshmallows - Marshmallows are what bind everything together and create that gooey, chewy texture. Use fresh marshmallows for the softest results - older marshmallows can make the mixture firm up too quickly.
Vanilla Extract - A small amount of vanilla enhances the sweetness and adds a warm, bakery-style flavor that makes these taste extra homemade.
Pastel Colored M&Ms - The M&Ms add a pop of color and chocolate crunch to this classic treat. You can use pastel for spring, red and green for Christmas, or any seasonal variety to customize your M&M Rice Krispie Squares for parties and holidays.
Salt - Don't skip this! A touch of salt balances the sweetness from the marshmallows and M&Ms and makes the flavors pop.

How to Make M&M Rice Krispie Squares

This M&M Rice Krispie Squares recipe comes together in just minutes and requires no baking. Follow these simple steps for soft, chewy squares every time.

Step 1: Prepare Your Pan

Line a 9×13-inch baking pan with parchment paper and lightly grease it with cooking spray. This prevents sticking and makes it easy to lift the squares out for slicing later.

Step 2: Melt the Butter and Marshmallows

In a large pot over medium heat, melt the butter completely. Add the mini marshmallows and stir continuously until they are just melted and smooth.
Important: Do not overcook the marshmallows. Overheating can make your Rice Krispie squares hard instead of soft and chewy.

Step 3: Add Vanilla and Salt

Remove the pot from the heat immediately. Stir in the vanilla extract and salt to enhance the flavor.

Step 4: Fold in the Cereal and M&Ms

Working quickly, add the Rice Krispie cereal and M&Ms to the melted marshmallow mixture. Gently fold everything together until evenly coated.
Tip: If you want the M&Ms to keep their shape and not melt, let the mixture cool for about 30-60 seconds before stirring them in.

Step 5: Press Into the Pan

Transfer the mixture into your prepared pan. Place a piece of parchment paper or lightly greased plastic wrap on top and gently press the mixture evenly into the pan.
Do not press too firmly - packing the mixture too tightly can make the squares dense and hard.

Step 6: Let Cool and Slice

Allow the squares to cool completely at room temperature for about 1 hour. Once set, lift them out using the parchment paper and slice into squares.

Pro Tip for the Softest Rice Krispie Squares

The key to the best M&M Rice Krispie Squares recipe is:

Fresh marshmallows
Low heat
Gentle pressing

Follow those three rules and you'll get perfectly soft, gooey bars every time.

Tips for Soft and Chewy Rice Krispie Squares

If you've ever made Rice Krispie squares that turned out hard or dense, don't worry - a few small adjustments make all the difference. Follow these simple tips to get perfectly soft and chewy M&M Rice Krispie Squares every time.

1. Don't Overheat the Marshmallows

This is the most important step. Melt the butter and marshmallows over medium-low heat and stir just until smooth. Overcooking the marshmallows causes the sugar to tighten, which leads to hard Rice Krispie squares.

2. Use Fresh Marshmallows

Fresh marshmallows melt more smoothly and create a softer texture. Older marshmallows can make the mixture stiff and harder to mix.

3. Remove from Heat Before Adding Cereal

As soon as the marshmallows are melted, remove the pot from the heat before stirring in the cereal. This prevents the mixture from continuing to cook and firm up.

4. Gently Press Into the Pan

When transferring the mixture into your pan, lightly press it down. Do not pack it tightly. Pressing too firmly compresses the cereal and makes the bars dense instead of soft and airy.

5. Let Them Cool at Room Temperature

Avoid refrigerating your M&M Rice Krispie Squares. Chilling them can make them firm and lose that soft, chewy texture. Let them set naturally at room temperature instead.

Quick Fix: Why Are My Rice Krispie Squares Hard?

If your Rice Krispie squares turn out hard, it's usually because:

The marshmallows were overheated
The mixture was pressed too firmly
There wasn't enough butter
They were stored uncovered and dried out

A little extra butter and gentle handling go a long way in this M&M Rice Krispie Squares recipe.

How to Store Rice Krispie Squares

Proper storage is key to keeping your M&M Rice Krispie Squares soft and chewy for days.

At Room Temperature (Best Method)

Store your Rice Krispie squares in an airtight container at room temperature for up to 3 days. Layer them with parchment paper between each layer to prevent sticking.

Avoid refrigerating them, as this can make the marshmallow mixture firm and dry out the texture.

Can You Freeze Rice Krispie Squares?

To freeze:

Let the squares cool completely.
Wrap individual squares tightly in plastic wrap.
Place them in a freezer-safe bag or airtight container.

How to Keep Rice Krispie Squares Soft Longer

Store in an airtight container immediately after cooling.
Add a small slice of bread to the container - it helps retain moisture.
Keep them away from heat and direct sunlight.

When stored properly, these M&M Rice Krispie Squares stay perfectly soft and chewy for days.
