Let me tell you, my life changed the day I decided to try making rice krispies in the microwave. I honestly can't believe it's taken me so long to make them this way. Growing up, my mom, sisters and I would always get the frying pan out and spend way too much time cooking them over the hot stove and making a huge mess trying to keep all the cereal in the pan! I will say, those are great memories and we always had fun making rice krispies the traditional way, but this new modern way of making them in the microwave is a quick and easy alternative that I love and I haven't gone back to the old way since!

I love making these rice krispie squares all year long. They're such a simple and versatile dessert to bring to potlucks, dinner parties, or just having around the kitchen for a sweet treat after dinner.
