Peanut Butter Crispy Marshmallow Brownies from - fudgy brownies with gooey marshmallows and a crispy chocolate peanut butter topping!One of my favorite things about food blogging is the food blogging community.  I have made some awesome blogging friends, who like to talk about food photography and blog plugins just as much as I do.

One of my very best bloggy buddies is Carla at Chocolate Moosey.  And when I mentioned to her that I needed a killer brownie recipe for the upcoming family reunion brownie bake-off for eternal fame and glory, she suggested I try her Peanut Butter Crispy Marshmallow Brownies.

It was a brilliant suggestion.  They are amazing.

Which is why I’m sharing them with you today.  I made a couple small changes, to make them my own and all, but overall, this brilliant recipe is all Carla.

The family brownie bake-off was a good time, by the way.  I still didn’t kick Maren’s butt, but I have high hopes for the next contest, which is all about cookies.

The big winner was actually Grandma.  No surprise there, the woman is a fantastic cook and baker, despite her inability to smell the amazing things she makes.  Her winning bar was very similar to this one, which is so addictive I literally had to quit making it.

I also attempted a second brownie, this one with a mint cheesecake swirl, but I never could get the thing to bake all the way through for some reason, and it was really too gooey to be enjoyed.  #foodbloggerproblems  We all have those days, right?

What I love about this brownie is everything.  Honestly.  That crispy chocolate-peanut-butter topping is to die for.

One suggestion:  I have tried them warm and cold, and I recommend eating them cold.  The marshmallow is easier to eat, the topping has a nicer texture, and they cut cleanly into pretty little squares.  It’s a win-win.

Even if it didn’t win the family reunion bake-off.

Serves: 16
  • ½ cup butter

    A few very important things to note:

    1) While Grandma is a very FANTASTI C cook, the recipe she used was mine (just sayin’),
    2) Your brownies were ultra-delicious; I especially liked the crunchy topping, which I could have eaten all by itself and been a happy girl,
    3) You are still going down two years from now for the cookie bake off. I have already discovered a secret recipe that will blow your socks off. But probably not the judge’s, since this year I was sleeping with one of the judges and I still didn’t win. We’ve really got to work out this judging situation…

      Maren… claiming Grandma’s recipe now?? This is a new low. Nothing against Grandma, but those weren’t brownies. Although, they were amazing. Also, not sure if you noticed, but I have a few super delicious cookie recipes in my back pocket. 😉 I think I’ve got a shot at this one!
