Brookies are one of my favorite desserts. It’s what I make when I can’t decide if I want brownies or cookies.

Normally I make brookies using chocolate chip cookie dough.

But today, I had this incredible craving for peanut butter and chocolate. Anyone else ever get this craving?


The cure for this craving was to make an over the top dessert combining my favorite brownie recipe with my favorite peanut butter cookie recipe. And throwing in some Reese’s PB cups, of course!

The dark rich chocolate brownies on the bottom of the Brookies is the first step to creating this ultimate dessert. I love using this brownie base on it’s own or topped with butterscotch and KitKatsIt’s fudgy and rich and just perfect in every way a brownie should be!

I topped this brownie base with peanut butter cookie dough. Soft and chewy peanut butter cookies. On top of a brownie.

With Reese’s mini peanut butter cups.

Must I repeat myself? These are amazing.

I refrigerated the cooked and cooled Brookies before cutting. It helps you get perfectly square cookie bars, with beautiful lines. And that’s important. Because a cold Peanut Butter Brookie tastes just as delicious as a room temperature one, you decide how you like to eat yours!!

    These look amazing. I’ve made your brownie base before and they are fantastic…but don’t they have cocoa? Is this base different?

    • posted Jul 7, 2013 at 2:06 pm

      This base is a little different. Instead of cocoa I melted chocolate morsels. You could use either version :)

    Oh my GOSH… When it comes to treats, there really isn’t a better combo than chocolate and peanut butter. Your brookies look AMAZING and I can’t wait to try them!

    Wait – I’m confused! Did you make these with the brownie recipe and peanut butter cookie recipe you said you used, and linked to? Or is the pictured bar made with the recipe further down the page? They don’t match. I’d like to make them so they look like the ones pictured.

    • posted Jul 18, 2013 at 5:37 pm

      Hi Dee, great question! I actually used the recipe in the recipe box, I made a few alterations to get the consistency and texture I wanted. ENJOY!!!

    I noticed you use a lot of crisco in your recipes. Crisco isn’t something I normally use, could I use butter instead?

    • posted Jul 19, 2013 at 8:49 am

      You can definitely substitute unsalted butter for the Crisco. I occasionally use Crisco when I’m looking for a certain texture! ENJOY!

    I just pulled my batch out of the oven, and it smells awesome.

    I made this recipe and it was wonderful! All of my co-workers loved them! Sinfully delish! I baked them for 35 minutes and the top got a little brown, but they still tasted great. I would just keep a closer eye on them and bake them for a shorter period of time.

    Hi would love to make these, can you tell me what butter flavoured crisco is? I’m in Australia and haven’t seen this before. Thanks

    • posted Apr 21, 2014 at 2:59 pm

      Crisco is shortening. Here in US they have butter flavored.

    I baked these for a bake sale and they went over quite well. I agree that the bake time should be less than 35 min as mine were a tad crunchy on top…awesome recipe!

    These are absolutely delicious. I have tried a brookie before and gave up because the brownie part was gooey and the cookie was dry. So I tried this recipe and baked it in my pampered chef stone ware 9X13 pan. It tasted good, but did not look like yours. The only changes I made to my recipe was to use all butter and no Crisco and a variety of chips instead of Reeses PB cups.  The brownie was slightly gooey, but the cookies was slightly overcooked especially on the edges. Do you think next time I should cook the brownie layer for about 5 min. then top it with the cookie layer? Would 350 degrees work? Should I use a glass pan instead?I really love brookies and would like to find a way to make it work so I’d appreciate suggestions. Thanks for the delicious recipe.

    • posted Jan 21, 2016 at 4:54 pm

      I too have Pampered Chef stones, and find that bars like this need a longer baking time. The crisco DOES make a difference in the cookie base, so switching to all butter will make a slight difference in the browning part too.
