Crack brownies

Have you ever tried crack? Yeah, me either. After eating these brownies, though, I feel like I would probably be less addicted to crack. I mean, how can that not be the case with brownies, peanuts, marshmallows, Reese's peanut butter cups, chocolate, peanut butter and Rice Krispies all present in a single bite?! This recipe comes from my very good Heather, and I am very grateful that she shared it!

Prepare 1 package of brownie mix according to the package directions. Coat a 9x13 baking dish and bake in the oven, also according to package directions (20-25 minutes).

While the brownies are baking, chop enough Reese's peanut butter cups (I used minis) to make 1 cup. Feed extras to hungry children running by, or pop them into your own mouth.

Add on top of the baked brownies:

1/2 cup salted peanuts

1 cup Reese's peanut butter cups, chopped

2 cups miniature marshmallows

Return to the oven and bake at 350 degrees F for an additional 5 minutes, or until the marshmallows begin to puff and brown and the chocolate begins to melt.

In a medium bowl, combine:

1 1/2 cups semi-sweet chocolate chips

1 1/2 cups creamy peanut butter

Microwave on high for 1 minute and stir until melted and creamy. 

Add 2 cups of Rice Krispies cereal and stir until completely coated with the chocolate-peanut butter mixture.

Pour mixture evenly over the brownies.

Refrigerate for a minimum of 2 hours before serving. 

Cut into squares, and prepare to feel like you might need addiction counseling.

You think I'm kidding!

Definitely delicious! Looks amazing! Got to try it.

I stumbledupon these today. I made them today. They were awesome and were a hit on the entire floor of my dorm. I left out the peanuts and subbed the mallows for fluff. I dont know if that is any better, I'll just have to make the original next time...... which is definitely a guarantee!

Reese's cups, marshmallows, and Krispies? OH MY! These look outstanding and have all my favorite things, definitely going to have to include these in my ventures into baking...

It looks great...thanks for the recipe, I'll try it!

Man those look delicious!!

I am about to make these for Thanksgiving. After you refrigerate these and cut them, do you have to keep them refrigerated or can you leave them out because they've hardened already. I've made cake balls before and they've become kind of sweaty after I had them in the fridge and I don't want this to happen to these!! They look sooo good! Thank you for this! :-) Anyone know this answer?

Hi Karla! These can be kept in the fridge or at room temp, depending on how you like them. If you want them to keep longer, fridge would be best. Otherwise, they are great on the counter, as well!

wow, no wonder they're called crack brownies. They're filled with the best stuff ever---on top of BROWNIES! Can't beat it! I love recipes like these that incorporate a lot of pre-made candy ingredients mixed with something that you just whip together. Great stuff, and post! Thanks!

Oh wow, these look great! The name is definitely fitting I think I could eat the whole batch!

I made these for my high school jazz band, and I forgot to buy peanuts. So, I just mixed half of the creamy peanut butter with extra chunky peanut butter.

It's so amazing.

Oh my mom used to make something like this but with a cake mix bottom instead of browines. yours look amazing!! So dense and chewy! YUM

Very tasty reading brownies. Hope they aren't as addictive as crank is supposed to be or you'll never make anything else ever again!

Wow these brownies look mouth watering! I def need to make these. Yum!

Made these for Easter and they were so good! Usually my friends tease me about my bad cooking, but they turned out so good that everyone was raving about them! Wish I had toasted the marshmallows a bit longer and gotten them toasty brown on the tops before added the krispies.

When I try to Pin this to Pinterest, no pictures show up :(
