Peanut Butter Brownies

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 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 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.

Peanut Butter Brownies
Recipe from bettycrocker.com

  • 1 1/3 cups packed brown sugar
  • 1/4 cup butter, melted
  • 1/2 cup creamy peanut butter
  • 1 tsp vanilla
  • 3 eggs
  • 1 1/2 cups all-purpose flour
  • 3/4 tsp baking powder
  • 1/4 tsp baking soda
  • 1/2 tsp salt
  • 36 mini peanut butter cups (Reese’s are the best!)
  • 1/2 cup milk chocolate chips

Pre-heat oven to 350 degrees. Grease bottom of 9×13 inch baking dish.

In the bowl of a stand mixer, beat together sugar, peanut butter, butter, vanilla, and eggs until well blended. Mix in flour, baking powder, baking soda, and salt.

Cut 12 peanut butter cups into quarters and gently stir into brownie batter along with the chocolate chips. Spread into baking dish and bake for 25-30 minutes or until a tester comes out fairly clean.

Remove from oven and immediately press remaining peanut butter cups into the top of the brownies in even rows. Allow to cool before cutting and serving.

    Wow hello deliciousness!! I remember trying to make peanut butter brownies before but got halfway through and realized I didn’t have enough eggs. I love that there are peanut butter cups chopped up and in the brownie as well as on top. And that it’s not a chocolate based brownie so I guess it’s a peanut butter blondie. Yum!

    OMG! Can’t wait to try these! They look fabulous!
    Love the picture!

    Question – when you make cookies (say chocolate chip) what do you store them in? Every time I make cookies, it seems that by the next day they don’t seem as fresh and are a little stale.

    Lea,

    I usually just store cookies in ziploc baggies. My husband inevitably leaves the bag open after getting a cookie out though, so I’m not sure how effective the bag method really is. ;) I do have these fun jars with suction-y type lids that work wonderfully, but I keep my flour and sugar in those. I got them for super cheap at TJ Maxx or Marshall’s and they would work great for cookies…if your husband is a good boy and remembers to put the lid on the jar.

    of course reese’s are the best! there is no substitution when it comes to peanut butter cups. these bars are worth every calorie, and that’s that. :)

    Oh, these sound really good! I might wait until Sunday afternoon to make them, and then send most of them to work with hubby. I don’t have any Reese’s cups, though. I’ll need to go buy some. How sad for me!

    These look amazing! Just a note, I was reading the recipe (trying to figure out whether I had everything to make these RIGHT NOW), and it looks like the post doesn’t include when you actually add the peanut butter. I found the full directions on the bettycrocker website, but I thought you might want to adjust the directions since we wouldn’t want to deny anyone any peanut buttery goodness. Thank you so much for posting this recipe; I’m already in bliss just thinking about these brownies!

    I made them and we LOVED them. I would add more peanut butter next time…and maybe more pb cups (and only half them instead of quarter them) in the batter. I made them Saturday afternoon and they are gone as of this morning! YUM! :)

    OMG Karly! That third photo with the Reese’s sticking out of the batter nearly did me in! No wonder your son has the dreamy “I’m thinking about Mom’s brownies” look.
    Calories? I’m not going to think about it!

    I sent the picture to my husband – an original peanut butter nut – and his reply:
    “Make em Make em Make em Make em Make em Make em Make em Make em Make em Make em Make em Make em Make em Make em Make em Make em Make em Make em Make em Make em Make em Make em Make em Make em Make em Make em Make em Make em Make em Make em Make em Make em Make em Make em Make em Make em Make em Make em Make em Make em”
    So I guess I will.

    You just gave me the tools to become the best girlfriend EVER. My boyfriend eats peanut butter out of a jar and calls it dinner, so I can’t wait to make these for him! Hmm. Or better yet, I could use them as a bribe of some sort…

    I’m not sure what I could have done differently, but I found them to be dry and devoid of the peanut butter flavor I was craving, sadly, as I love peanut butter!

    I’ve been wanting to make peanut butter desserts for such a long time now!!! These look so chewy and gooey………Oh I can’t wait until I can make these! I havent been able to bake anything with peanut butter though because my brother doesnt like peanut butter, and if I bake something sweet, he’ll definitely want to eat it. Great recipe and photographs though!
