    National Oreo Day is something to celebrate!

    March 6 is National Oreo day. Now THAT is worth celebrating!! Oreos are my favorite "from a store" cookie. Let's face it, they're not easy to replicate at home so I'm not even going to try.

    Instead, how about combining Oreos with something just as iconic and something made at home such as . . .  Rice Krispie treats!

    Mixing Oreos and Rice Krispie treats makes Oreo Krispies. And after your kids eat them, they'll be called, "These are FANTASTIC, Mom!"

    A few Oreo factoids

    Since this is "their day" let's look at a few fun facts about Oreos:

    • Over 450 billion Oreos have been sold since their introduction
    • Oreos are sold in more than 100 countries worldwide
    • More women dunk an Oreo than men
    • More men eat Oreos whole than women
    • Oreos are 71% cookie and 29% creme filling

    I don't know about you, but I was a little startled by the information that men are NOT dunking and are just eating the chocolate sandwich cookies whole. All at once. Savages!

    I always felt there was no way an Oreo could be improved. Then came the Double Stuf. Oh my. And then? Fudge dipped. No fair!

    How to make Oreo Krispies

    For this recipe, I have used both standard Oreos as well as Double Stuf. They are fantastic either way. 😃

    So many Oreos, so little time…..mmmm.

    Speaking of time, this comes together super fast! Just measure out the Krispie cereal with one cup of mini marshmallows in a large bowl. Crush up 16 Oreos and add them to the bowl.

    I'll email this post to you, so you can easily come back to it later!

    Then, use medium-low heat to melt butter in a saucepan, add remaining mini marshmallows to saucepan and stir until the marshmallows have melted completely into the butter. If you prefer, you can use the microwave for this step, just heat long enough to melt the butter and marshmallows, then stir well.

    Remove from heat and pour over the cereal mixture. Stir everything to coat the cereal mixture with marshmallow goodness. Spread this mixture into a buttered pan and press gently to flatten the top.

    The typical tool for this is a spoon or spatula. I like to use a sandwich bag to grease the pan and then reserve that bag to press the top of my Krispies. Works great, no rolling pin required. 😀

    Now comes the hardest part: Wait - til the pan cools for 30 minutes before cutting.

    Anyone else just love how gooey treats pull apart?

    These Oreo Rice Krispie treats should come with a warning label. They are wicked good!

    Storage

    Store your delicious treats at room temperature in an airtight container. They will be good for about 3 days, although they might not last that long!

    More delicious treat ideas

    For another snackable treat, consider making a Fruit Pizza.

    Got leftover Oreos? You might want to make some Oreo Cupcakes with Oreo frosting. Or make an Oreo crust for a delicious White Chocolate Cheesecake.

    It doesn't get much better!

      These looks so dangerous! They're easy to make and would disappear before you know it! And not using double stuffed, Sula? Not cool. I don't know why Oreo even bothers to make the original stuffed anymore. Sick!
