Frequently Asked Questions

How far in advance can I make these?
You can make these 1-2 days in advance and store them in an airtight container.

How can I make these thicker?

If you want super thick rice krispies treats, you can double the recipe or use an 8×8 pan, except for the cup of cereal on the top. That amount will remain the same, unless you want less.

Things to Note:

• You may not have to leave them for an hour, as they often set pretty quickly. However, I tend to let them have plenty of time to rest as they’re easier to cut and less messy that way.
• You don’t have to add the mini marshmallows into the mixture. You can replace it with more cereal. It calls for 2 cups mini marshmallows so swap it for 2 cups cereal.
• Don’t press the mixture down into the pan too hard or you’ll make the treats tough. They’ll pack really tight making them like jerky tough. Believe me…I made this mistake before. Don’t do it!
• You can make the butter and marshmallow mixture over the stove instead of the microwave, if desired. It’s just quicker to use the microwave, which is why it’s my cooking method of choice.

How to Make Lucky Charms Rice Krispies Treats

Slice your butter into chunks and combine it with 8 cups of mini marshmallows in a large mixing bowl. Microwave for 2 minutes.

Immediately stir until the marshmallows are no longer chunky and the butter is fully mixed in.

Add the remaining 2 cups marshmallows and 5 cups Lucky Charms to the melted marshmallows and gently fold together until the cereal and unmelted marshmallows are fully covered.

Spray a 9×13 cake pan with nonstick cooking spray. Add the mixture to the pan and gently spread even in the pan.

Sprinkle the remaining cup of Lucky Charms over the top and lightly press to ensure it sticks to the top.

Let rest for about an hour or until set.

Slice into squares and enjoy!
