Chocolate Oreo Rice Krispies Treats in the Microwave (aka “baking” with no kitchen)

A church near our house hosted a Strawberry Festival last weekend. I was checking out the website and I found out they were also doing a bake sale and looking for people to donate baked goods. Of course I wanted to help out, but there was one minor problem… Oh right, we have no kitchen right now! Well I started thinking about things I could make with just my box of baking supplies and a microwave. A came across quite a few recipes and decided on these Oreo Rice Krispies treats. Who wouldn’t love these?

And I found out that Hubby apparently really loves Rice Krispies Treats. He said he’d only ever had plain ones, but I think I may have converted him to loving them with something mixed in. I used a 9×13 pan because I like mine thicker. And I cut them fairly large since they were for a bake sale. I got 12 our of each 9×13 pan.

They came together in a snap. I used the cabinets which are still in boxes as counterspace and the hardest part was cleanup. Washing big bowls in a bathtub is NOT fun!

Chocolate Oreo Rice Krispies Treats – from Recipezaar1/3 cup butter or margarine
5 cups mini marshmallows – I used a package of regular marshmallows
3 tablespoons unsweetened cocoa powder
1 teaspoon vanilla
6 cups Rice Krispies
15 Oreo cookies, coarsely chopped – I just threw them in a ziploc bag and crushed them with my hands

Butter an 11 x 7-inch pan (I used 9×13).

In a large microwave-safe bowl heat the butter or margarine with marshmallows and cocoa powder on HIGH powder for 3 minutes, removing after stirring each minute.

Mix in vanilla then add in the cereal and chopped Oreo cookies; mix with a wooden spoon until well coated.

Transfer to prepared pan then press down with back of a spoon to spread evenly.

Allow the mixture to cool slightly, then cut into squares.

    This looks AMAZING! What did you use to hold the Oreos in place on the top? Is that Oreo filling?

    Love this cake – made it for my hubby’s 30th! Just a quick question as I had a little trouble with the Oreo filling. It was a bit thin. I think the problem might be the type of cream I used as we don’t have heavy cream in Australia (at least it’s not called heavy cream) so does anyone know what type of cream I should use? Thanks heaps 🙂

    This cake turned out amazing! I omitted the coffee from the frosting and it was perfect without but im sure it would have been prefect with. It was a process to make it but well worth it! Just as good if not better than a bakery cake!

      Yes, it’s definitely a lot of work, but worth the effort! Glad you enjoyed it.

    • beantownbaker — September 2nd, 2014 @ 7:09 pm

      Did that work for you? I will have to check next time I am at the store. I just get the standard size with 3 rows.
