Peanut Butter Cup Crunch Brownie Bars

So, do you happen to remember the insane brownies that I made quite awhile ago, the Marshmallow Crunch Brownie Bars? They’re a layer of brownies, then ooey gooey marshmallows, and then topped with a combination of melted chocolate, peanut butter and Rice Krispies. Well, those brownies and these brownies could be sexy twin sisters. What’s going on here is a layer of chewy, fudgy brownies, topped with peanuts and chopped peanut butter cups, and then topped off with that same melted chocolate/peanut butter/Rice Krispies mixture. Insanity. In an insanely good way.

I found these brownies on How Sweet It Is, and Jessica called them “Better-Than-Crack Brownies”. Addicting would be an understatement. Also, no surprise that something like this showed up over there – us Pittsburgh girls seem to have very similar tastes in our sweets! :) I also found a version of this recipe over on Babble – it includes a full-on peanut butter layer in the middle instead of the peanuts and peanut butter cups. I may have to give that one a shot too. Oh, who am I kidding? “May?” Of COURSE I am going to make those too!

For the brownie base of these you can use your favorite brownie recipe. They are best with a chewy, fudgy brownie vs. a cakey brownie. I think these Chewy Brownies are perfect for the job, but use whatever you’d like, just make sure it’s a recipe for a 9×13-inch baking dish (not an 8×8 or 9×9).

Don’t say I didn’t warn you about how addicting these are, but your life will certainly be more complete with these babies in it!

Peanut Butter Cup Crunch Brownie Bars

Yield: 24 brownies

Prep Time: 20 minutes

Cook Time: 25 minutes

Total Time: 45 minutes

Ingredients:

1 batch of your favorite brownie recipe for a 9x13-inch pan (I recommend Chewy Brownies)
½ cup salted peanuts
8 Reese's peanut butter cups, chopped
1½ cups milk chocolate chips
1½ cups creamy peanut butter
½ tablespoon unsalted butter
1½ cups Rice Krispies cereal

Directions:

1. Prepare the brownies according to the directions and bake for about 5 minutes less than the recipe states. Remove from the oven and sprinkle the top with the peanuts and chopped peanut butter cups. Return to the oven and bake for 5 additional minutes.

2. While they are finishing baking, melt the chocolate chips, peanut butter and butter in a medium saucepan over medium-low heat. Stir in the cereal to evenly coat. Remove the brownies from the oven and evenly pour the chocolate and peanut butter mixture over top. Spread to cover evenly. Refrigerate for 2 hours before cutting and serving. Store in an airtight container in the refrigerator.

    Every time I see a spin on this I want to make it. Brownies with peanut butter anything are so good but the idea of the rice krispies that add a crunch is just so good!

    Michelle, I’ve made a very similar recipe (the brownie recipe is slightly different.) These are awesome!! Wanted to tell you about a variation I have made, which might appeal to others. My son loves chocolate, but isn’t a marshmallow fan. I have replaced the marshmallow with a bag of caramels, melted with 1/4 cup half-and-half. I may even like that better. But hey, I wouldn’t turn down either!

    As for spreading the chocolate/peanut butter topping, as someone mentioned having difficulty with, I find it easiest to wait about 5 minutes, then put small dabs of it (maybe about 1 tsp to 1 TB – not necessary to be precise) over the entire surface, not being too particular – just dropping it all over quickly) and, using the offset spatula like you mentioned, then spread the stuff. When you only have to spread a tiny area to meet up with the next, it’s much easier to do.

    This might be sudden… but… will you marry me? :)

    Honestly, that brownie is insanely awesome. I have an unhealthy relationship with peanut butter and anything peanut butter and chocolate (or peanut butter and anything :)). I built what I dubbed the “ “Epic Brownie” for Christmas which was 4 layers of different chocolates and chocolate textures. However, I now realize my error and wish it had occured to me at the time to add a layer of peanut butter or peanut butter cups :). Simply brilliant ! :).

    I keep complaining because everyone keeps making all of these amazing peanut butter related recipes. This, Looks, INCREDIBLE. I’m tempted to grab some peanut butter cups on the way home.. I have the other ingredients. But I DO have a batch of peanut butter chocolate chip cookies waiting to be baked in the fridge. All these peanut butter posts drove me crazy, so I made the dough at 10pm last night :P

    Those brownies look deliciously decadent. On a side note inspired by your cookie topped borwnie link at the bottom of the post… I’m playing with an idea for a brownie bar that has a chocolate chip cookie dough bottom with a brownie layer on top. All the recipes I’ve seen for any type of layered bar put the brownie batter on the bottom. Any one know why??

    Reply

    • Adam on February 17th, 2011 at 7:21 pm

      The brownie requires a longer bake time to bake through. The cookie layer on the bottom will stifle the heat coming from below and the potential for the cookie bottom to burn before the brownie is baked will increase. I did something similar with a layered brownie, where I put a crumb crust and a layer of fudge before the brownie layer and it added another 15 minutes to my bake time. To counter this you’d probably want to chill the cookie dough before adding the brownie batter and putting it in the oven.

      • Laura on February 17th, 2011 at 7:30 pm

        Thanks, Adam. I’ve done brownies on a shortbread crust (pre-baked) and didn’t have any problems. For my current idea, my plan was to make individual “bars” in a lined muffin pan that has chocolate chip cookie dough on the bottom, brownie on top, and then frost them with chocolate chip cookie dough frosting (or eggless raw cookie dough) and decorate hem with a cookie wedge. Do you think that making them in a muffin pan might eliminate the problem of over baking the cookie dough?

        Reply

        • Adam on February 17th, 2011 at 7:38 pm

          I’d say that if you load the pan with cookie dough and chill, and perhaps lower the oven temperature (if its 350F) I’m sure you’d be okay. It’s not something I’ve done before, but I’m curious to hear the results. I’m actually thinking of doing something similar but in a pie form :).
          Oh and by the way: That sounds awesome :) Good luck :).

          Reply

          • Laura on February 17th, 2011 at 9:06 pm

            Again, thanks! I remembered that I’d baked both brownies (as a base for an ice cream cake) and cookie dough (as a “Cookie cake”) in my 4 1/2″ mini-springform pans. Ironically the cookie dough baked longer, 15 min @ 350 and then 15-18 at 325. The brownie base only took ~18 at 325. I think that the cookie dough was slightly chilled, and probably thicker than the brownie batter, but it gives me hope that my idea will work. :) Your pie idea is intriguing.
