Doctors and researchers are making progress yet only 4% of the money raised for cancer research goes to pediatrics. My food blogger friends and I develop recipes to raise awareness and money for the fight against pediatric cancer. We raise thousands each year and some amazing and generous brands have partnered with us to match our donations.
These fun rice Krispie treats were my contribution to an amazing cause. I’ve played with the ratios of cereal to marshmallows many times and these are definitely the best. Each square is sweet, thick, and super marshmallowy.
Tips & Tricks
- I like adding the third bag of marshmallows in with the cereal once the pot is off the heat. The residual heat melts them just enough to be sticky yet still hold some shape.
- If you do not have an offset spatula, you can use your clean hands to press the mixture into the pan. Spray your hands with a bit of cooking spray to keep the mixture from sticking.
- Don’t pack the mixture too tightly. If it is too compressed your bars might become hard as a rock.
- To cut clean squares. make sure the pan of Rice Krispies treats has cooled completely.

FAQ
Can you add food coloring to melted marshmallows?
Yes. To dye the melted marshmallow mixture, simply fold in 1 to 2 drops of food coloring at a time until the desired color is reached.
How do you keep Rice Krispie treats from getting too hard?
To achieve the perfect texture, be sure you’re using fresh marshmallows melted over low heat, and do not pack the mixture in the pan too tightly.
Can you use mini-pastel marshmallows for Rice Krispies treats?
Yes, but the colors will bleed together once melted, so I recommend replacing the third bag of marshmallows with a bag of mini-pastel marshmallows and adding them in with the cereals. They are supposed to be fruit-flavored so the taste will be a bit different.
