Canarsie Cookies Peanut Butter Brookies

Today’s recipe is from Stef, who loves to bake and share recipes on Canarsie Cookies.  This “Peanut Butter Brookie” is one of her creations, and I was lucky to be on the receiving end of a half dozen.

Peanut Butter Brookie

Stef makes her brookies (half brownie, half cookie) with organic peanut butter cookie dough and brownie batter and bakes them in a paper lined square muffin or bar cookie pan. This makes a lovely presentation, plus the shape is also perfect for packaging and shipping. For my package, she wrapped six brookies individually, fit them into a rectangular Ziplock container, and tied it all together with a ribbon.


The stamped labels were a nice touch, too!


So thanks to Stef for sharing her recipe, and I look forward to making it very soon. In the meantime, here’s Stef’s write-up on how her Brookie’s came to be.

The Organic Peanut Butter Explosion Brookie by Stefanie Mysel

One of the coolest things I used to do as a girl was constantly mix up flavors of well…anything. My friends and I lived outside Allentown, PA and would go to a place called Rita’s. They stayed open during the summer and sold Italian ices mixed with different flavored custards. It got me thinking…what if you combined your favorite recipes into one? So I decided to try different combinations and just happened to have a group of testers. Who were the testers? My husband’s golf students. Here’s what happened…I began testing recipes out on the golfers to see what really caught their attention. One afternoon my husband taught a long driving class and we came up with a “power” recipe. A peanut butter cookie on top of a chocolate brownie. The results were amazing! We got feedback like, “love the class…can you bring me one of those cookie combo things too?” From there, if we tried a recipe and it didn’t get that kind of feedback, we trashed it. So this recipe you’re about to see was tested by 50 people and was sold at the golf course.In terms of using organic ingredients. You don’t have to for any recipe but what we found is organic ingredients bought from farmers markets tend to last longer, taste fresher and in some cases can be less expensive. If you go later in the market session, often times you can score deals because the vendors just want to reduce leftovers. That’s when you get bargains.

    How truly awesome would these be for a bake sale?! They look like a little treasure and so much more than a cupcake.

    I love the idea of a square cupcake pan, have never seen one. Where do you find them?
    Brownies and cookies together and then choc. glaze…. to die for, now I want to make them!

    Hi Karen,

    A company called Wilton makes them as well as silicone square baking cups. Something I experimented with. Sometimes the brookies got thick so it actually made them easier to eat making them with corners.

    Funny thing is people just remembered the shape when we tested them versus round ones. Let me know how they turn out when you bake!

    Karen, I put a link to Amazon so you could order one. Otherwise, check Kohl’s. Kohl’s had them last weekend when I was there shopping for a cake pop maker.

  5. Phyllis says

    Am confused about what type of pan to bake these in…. Mini muffin pan, regular 8×8 pan ( then cut up into squares), or square silicone Wilton mini muffin pan? Can you help? They don’t look like the were cut….Thanks…

  6. Laura says

    I would like to make brookies. I don’t have a pan like this and don’t want to buy one.
    Would a 9×13″ work?

  7. says


    Yes that will work. You can do one of two things: 1) cut them after they cool or 2) or use a cupcake pan.

    Either one will work. The pan I use saves me some time and people for some reason love the shape.

    Let me know how it comes out!
