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.

Made these, INSANELY GOOD! They rocked, I rocked them. I bumped the recipe up by about 50% to accommodate a 9×13 pan and used my go-to non-mix brownie recipe and despite cooking them at 350 instead of 325 for 35 minutes which made them weird like crumbly cake they were still awesome. I can’t wait to try them with proper brownies for the base!! You rock girl! Crack is a good name!
These look AMAZING!
The pan size has been discussed already, but I wanted to clarify: the original BHG recipe calls for a 9×13 pan. So you just opted for the 9 inch pan and kept everything else the same, right? Did you really get 25 out of a 9 inch pan?
Well, I cut them small, because they are a little thicker. I tweaked some of the ingredients in the BHG recipe slightly to suit my taste, like adding more krispies…but I just prefer a thicker brownie!
A brownie addiction? Blasphemy.
Oh. My. Goodness. Love the krispie cereal – chocolate – peanut butter layer – pure awesomeness!
Was looking for a dessert to take to the school book fair on Monday. Found it! Thanks!
I am pretty sure that’s why four pound buckets of peanut butter remind Glory of you, lol! True story!
My thighs think you are the devil. But my stomach thanks you! 😉
Copy that!
I made these last night and my girls and I just tried them-OMG! We’re in a sugar coma now, and it’s totally worth it. I’m taking these to a dinner tonight, and I’ll be surprised if any of them make it home!
BTW, I made these in an 8 x 8 pan, and didn’t reduce any of the ingredients. They still turned out great…look forward to trying more of your recipes.
Whoops- ingredients, not recipes.
