Peanut Butter Brownies

These peanut butter brownies are one of the best bar desserts out there! Just wait til you get a taste of all that peanut butter!
These peanut butter brownies are so rich and chewy! You'll love them!

I apologize for what I’m about to do to all you skinny girls on diets. Your thighs and hips and butt and waist will never be the same. It’s my fault. I’m a naughty girl. I can’t hide this recipe from you though. It’s just too good to keep to myself.

Besides, if I have to gain 500lbs eating these Peanut Butter Brownies, so do you.

It’s the law. My law.

And, okay, so I don’t have the authority to make laws, but I’m pretty bossy, so you should just listen to me and make these peanut butter brownies.

I, for one, had never seen peanut butter brownies before I came across this recipe. Sure, there are tons of recipes with peanut butter cups or peanut butter added to regular brownies, but these guys are made from a peanut butter base. And, yes, there are a few peanut butter cups thrown in for good measure.  We wouldn’t want to eat responsibly or anything, would we?

I mean, I love all brownies. My Nutella brownies are top notch.

I should mention that the batter for this is very thick. Don’t be scared. It won’t hurt you. I promise.

And, because chopping up peanut butter cups and putting them in the batter just isn’t enough, the next step is removing the brownies from the oven and squishing more peanut butter cups all over the top. Just do it. Don’t question me. Mama knows best.

That’s my son up there. You see that deep, soulful gaze of his? Wondering what he’s thinking so intently about? It’s these brownies. I’m sure of it.
