If you like chocolate and marshmallows and peanut butter and more chocolate…these brownies are the absolute best!  One year my daughter requested them for her birthday–instead of cake–and she and her three friends at the entire jelly roll pan of them before morning. (No, we didn’t have to take any of them to the hospital!)

Marshmallow Brownies up REAL close!

To begin, I make up a batch of brownies–just regular, everyday fudge brownies. If you can’t buy the Betty-Crocker-type, do what I do, and make my recipe for One Bowl Brownies. Instead of putting the batter in a 9X13-inch (22X33 cm) pan however, I put the brownie batter in a greased jelly-roll pan. (A jelly-roll pan is basically a baking sheet or cookie sheet with sides. It should measure around 11X17-inches  or 28X43 cm.)

So I pour in the batter…

…and spread it around…

I bake the brownies at 350° F (180° C) for 15-18 minutes.  I can’t tell you exactly how long, because everyone’s oven is a little different. However, I usually err on the side of underdone because there are few things worse than a dried out, overdone brownie. The batter should be dried out a bit on top…but still a little soft and “jiggly”.

While they’re in the oven, I get my marshmallows ready. Since Kraft hasn’t yet found it’s way to Italy, I can’t find mini-marshmallows here, so I used these multi-colored ones, which I cut up with scissors to be close to the size of mini-marshmallows…

They’re actually quite pretty, aren’t they? You might wish you could buy them where you live! I sprinkle these over the baked brownies…

…and pop them back in the oven just long enough to poof up and melt so they “stick” to the brownies…

If you prefer, you can make your own Homemade Marshmallows and pour the mixture over the baked brownies. No need to put them back into the oven since the fresh marshmallows will adhere nicely to the brownies. Whichever type of marshmallows you use, you’ll want to now let them cool, while you mix up the topping. “You mean there’s MORE?”, you ask. Yes! The best is yet to come!

I melt some butter and semi-sweet chocolate in a small saucepan…

Once it’s nice and smooth…

…I stir in some peanut butter…

I get that all stirred in…and then add some crispy rice cereal (better known as Rice Krispies but that’s a trademark so we’ll go generic with “crispy rice cereal”)…

Please be careful not to drool into the luscious topping…instead, place dollops of it on top of the softened marshmallows…

…and then spread it all over…

Make sure it goes all the way to the edges. I feel bad for the person who gets the corner or edge who doesn’t get all that gooey-goodness!

Now, if you can stand it, let everything cool until the chocolate topping is firmed up. Then cut into squares and enjoy!

These are rich–don’t cut them too large! And such a large pan serves a gang…but if your group is small, you might have enough left over to wrap up individually in plastic wrap (or foil) and freeze…

My Good Husband is only too happy to pull one out of the freezer and microwave it for an after-dinner treat! I sometimes dropped one into my kids’ lunch bag…by noon they were thawed and brought a smile to their faces!

I wish I had some in the freezer right now! Just talking about them makes me want one. I want one NOW!
