Brownie Peanut Butter Magic Bars

Wellll hellllloooooo beautiful brownie peanut butter magic bar. How you doin’?

{Tell me the truth, you just said that in your best Joey voice, right? Could there be a better TV show?}

Brownie Peanut Butter Magic Bars

These kind of speak for themselves, am I right? I think I *may* have just blown your diets to pieces. Sorry.

Actually…I’m not really sorry. If I can’t avoid sugar than neither can you! 😉

I’ve been on a magic bar kick lately. I made monster magic bars, cookies ‘n cream magic bars, almond white chocolate magic bars, and I have a few more save to share with you. They are just SO easy to make and so sinfully good! The possibilities are endless.

These babies…well. The crust is a brownie. You know that whole “make a crust out of cake mix” idea? With one stick of butter and an egg? I did it with brownies.

{You’re welcome.}

Then I chopped up some peanut butter cups and added peanut butter chips and chocolate chips along with my favorite drink, sweetened condensed milk.

These brownies are a mouthful. They are a meal. Skip lunch and eat two of these bad boys. Take that Weight Watchers!

Could there be a better magic bar? I’m not sure…

  1. These are AWESOME.  Seriously.  So wrong and so irresistible.  I only have one thing to add….   when spreading the brownie “dough” – use a piece of saran wrap!  Put the dough in the dish in clumps and cover with a sheet of plastic wrap.  Then you can use your hands without making a mess (so much easier and faster than trying to do it with a spatula) and the cling wrap just peels right off.  Done and done.  WE LOVE THESE DARN THINGS.  Thank you!

  2. I love these! This is my 3rd time making them and today I am making 2 batches. I want to freeze a batch. Is that ok?

    1. Yes! I always freeze bars. Just make sure they’re in a tightly sealed container and in a single layer – the SCM may make them stick together if you stack them. A few Quart or a Gallon sized ziploc is perfect for this!

  3. I just tried to make the Brownie Peanut Butter Magic Bars and it was kinda an epic fail. The center did not cook. I had them in for 40+ minutes and they were just goo. Should I cook the brownies a little first then add all the toppings. The toppings got so brown that they didn’t look pretty to bring to a party. They still tasted fantastic what isn’t to love about those ingredients but I couldn’t cut them to serve.

    1. I’m so sorry Carrie! I suppose lots of things could cause that to happen, oven temp differences and altitude and those sorts of things. Cooking them for about 10 minutes first might work, or using a thinner pan possible too (like a jelly roll instead of a 9×13). I’m so sorry they browned too much. Sometimes, if I notice things browning too much, I’ll put some foil on top during baking. I’ve never done it to magic bars, but I have done it to pies. Sorry for the troubles!
