This is a treat that my kids beg for and it takes only about ten minutes of effort. These Oreo Krispies don’t really seem homemade because of the help they get from the cereal and cookie aisles. But trust me, they taste infinitely better than the pre-made krispie treats you can buy in the store. 

Oreo Krispies

In my opinion the basic rice krispie treat recipe needs a little extra oomph to really make them shine. I started with this recipe here and altered it a bit, including adding the crushed Oreo cookies. They are perfect. Extra thick with lots of marshmallow flavor. Some of the recipes I found when researching Oreo Krispies included melted white chocolate – which is fine if you are a fan of white chocolate. But I prefer the more classic flavor of the melted butter and marshmallows.

These Oreo Krispies are getting rave reviews on Pinterest. I’m floored by how many people are making them and snapping photos of their efforts. I had a recent question from a reader that I think others may wonder too:

Can you cut Oreo Krispies into shapes?

Yes! In this recipe I call for the treats to be spread in a 9-inch square pan because I wanted these Oreo Krispies to be extra indulgent. But if you spread them into a 9×13 dish they will be thinner and easier to cut using a cookie cutter. I would be sure to spray the dish with cooking spray or grease with a little extra butter to make sure the shapes are easy to remove from the dish.
