How To Make Peanut Butter Cup Crack Brownies:

So I started with a box of Ghirardelli Double Chocolate Brownies… they are some of my favorite boxed brownies. While they were baking I chopped up some peanut butter cups and honey roasted peanuts.

When your brownie has 5 minutes left to bake pull it out of the oven and sprinkle your peanut butter cups and peanuts all over the top. The chocolate will melt and then you can use an off-set spatula to spread the chocolate evenly on top.

Set all that aside and then in a microwave safe bowl combine chocolate chips, peanut butter and butter in a bowl and melt it in the microwave until smooth. Then stir in some vanilla, salt and krispie cereal. Pour that on top of the brownies and spread evenly.

Now chill the brownies for 2 hours, until the top layer is set.

Hi! I’m Shelly and I’m an addict. Of the buttercream sort. I started this site a few years ago as a way to justify my sugary, buttery obsession with desserts. It has worked out well for me so far, because as it turns out you guys all love sugary, buttery desserts too! It feels good to know you're not alone, doesn’t it?

If I use a 13×9 pan, do I double the recipe? And I have Reese’s miniatures, so how many would I use if I don’t have the regular size Reese’s cups?

How does a nine x nine pan make 25 pieces

May I use a 9×13 inch cake pan versus a 9×9 inch pan to make this recipe, or would that result in a thin brownie mixture? Also, would I be allowed to use a non stick aluminum foil to line the pan or stick with “regular” aluminum foil—if “regular” foil, do you recommend not to grease it a little? Please advise me. I am looking forward making your recipe and I do thank you.

I finally found and bought a 9 x 9 pan to make this great recipe. I mistakenly bought a fudge brownie mix versus your instructions using brownie mix. I read the recipe ad nauseam, so what do I do? I pick up the wrong type of brownie mix. Would I still be able to use the fudge brownie mix or will it be too sweet or just plain ruin the end result? I thought I had an IQ equal to that of a carrot but that may be debatable. As I stated in an earlier comment/question, I would appreciate your… Read more »

I have spent more time than I care to admit trying to find any store near my home (gas prices) that carries a box of brownie mix that is a smaller size than that of the family sized . I did read you said the family size would be thicker. I am not confident in my first attempt making these to have the outcome turn out thick. Also, may I use the same amount of shortening to replace the butter when melting the chocolate chips? I would truly like to make this for those who work at my Vet clinic… Read more »

I only have family size brownie mix at the house? Can I still use it? How does this alter the recipe?

These are delicious! I made them for a cookout with friends who enjoyed them as well. Easy to prepare.
Because I bought crispy cereal for this recipe, I made rice crispy treats as well. These 2 desserts together were a great balance because brownies are very sweet.

I omitted the peanuts and after I smooth out the resses I laid bite size pretzels on top. Drizzled caramel over that and then added the cereal topping. I call them my Take 5 brownies

I made these last night for our night shift Labor&Delivery potluck.
I bake a lot of stuff for midnight work potlucks but this is my girls’ new favorite treat!! They were SO good. The day shift wouldn’t let me take the few leftovers home!
The rice krispy/PB/chocolate topping was the best part, hands down.

Thanks for sharing!!!

Disappointed this recipe was a disaster for us, the Reese did not melt and the peanuts burned… I may try it again using the reese pb chips mixed with milk chocolate chips and no peanuts…
