Fluffernutter Cookies

These fluffernutter cookies have a soft peanut butter base and a thick and sweet marshmallow topping!

It’s cookie time, y’all. Because, really. Isn’t it always?

The truth is that no. It’s not, sadly. I’m back on my low carb diet, which means no cookies for me. Luckily, I had the sense to make this recipe the day before I started my diet and I got to eat as many of these cookies as I wanted because I knew I was starting a diet the next day.

That’s how you guys do the day before a diet starts too, right? You eat all the foods you know you won’t be having for a bit? And maybe gain a pound or two in the course of 24 hours all in the name of freedom?

Huh. Maybe I’m dieting wrong?

Anyway, I don’t hate my low carb diet. I eat bacon and eggs for breakfast every day. I have hamburgers with extra homemade mac sauce and no buns for lunch. I eat steak for dinner a few times a week. Yeah, yeah, there are vegetables involved, but did you hear about the bacon and the steak and the mac sauce? Makes the veggies doable.

Anyway, let’s back up to the eggs, shall we? As you guys must know by now, I’ve been working with Davidson’s Safest Choice eggs for, um, 2 years now. A little more than that even. It’s been pretty rad, because I legit love their eggs for a lot of reasons, like the fact that they’re pasteurized so when I make myself eggs for breakfast, I’m not the least bit concerned about serving them sunny side up!

And when I make cookies I get to eat the dough before I bake it. Like my favorite recipe for peanut butter cookies. The dough is so soft and it doesn’t require any chilling, which is always a bonus. The dough holds it shape really well so the cookies come out thick and puffy and delicious. But, let’s be real…the raw dough is just amazing, like a peanut butter ball!

So, I wanted to experiment a little and I turned my favorite peanut butter cookies into fluffernutters by adding a half of a marshmallow to the tops of the cookies! It worked so well. The marshmallow melts over the cookie and stays soft even after it’s come back to room temperature. What an easy way to frost a cookie and add a little pizzazz!
