What You’ll Need
Here are the ingredients you’ll need to make cookie bars at home. See the recipe card located at the bottom of the page for full details and instructions.
- Butter– For most of my recipes I use salted butter. Unsalted works too.
- Granulated Sugar– This fine white sugar adds sweetness to the cookie bars.
- Light Brown Sugar– Light brown sugar also adds sweetness and richness to the bars.
- Creamy Peanut Butter– Use your favorite brand of creamy peanut butter.
- Large Egg– For consistency, I use large eggs in my cooking and baking.
- Pure Vanilla Extract– Use pure vanilla extract for best tasting results.
- All-Purpose Flour– Flour is the main dry ingredient in the cookies.
- Baking Soda– Baking soda helps the cookies rise during baking.
- Kosher Salt– Kosher salt is a course salt commonly used in cooking and baking. I prefer it over table salt.
- Chocolate Chips- Milk or semi sweet is generally what I use. White chips and butterscotch would be good substitutions too.
- Mini Oreos– Mini Oreos are usually sold in a bag in the cookie isle. You can crush your own regular size Oreo cookies if needed too.

These look Just. Too. Good. Loving them 🙂
Looks delish!
I have no words, you did it again, Jenny!! 🙂
Oh my gosh- does it get any better than this?? I don’t think so!!
My, my, my!!! These look very addictive!
Ooooh I love those Guittard chips and anything with Oreos just has to be magical!
You cannot go wrong with these ingredients!
Your gorgeous photos helped me to envision the Guittard chips. First, I’d open the package and test a handful. Then I’d pour the required amount atop the cookie dough and test a few of those. Then I’d gently, carefully stir them into the cookie dough and test a few tablespoonfuls of the cookie dough. Then, moving on to the mini Oreos ~
Keep writing…
OH MY GOSH! I HAVE to make these! Looks delicious, thanks for the recipe!!! 🙂
These look super yummy…adding to my “need to make” collection of recipes.
Pinned. But then again, I could (and practically do) pin everything you post!
These look so moist and perfect!! Yummmmm!
These remind me of “the parent trap”, when they eat oreos with peanut butter, lol. These bars look great!
These would definitely be #1 on my list of back-to-school treats! 🙂
these look sooooo good…i love the contrast in color in the chips vs. oreos too! not that it REALLY matters, but pretty nonetheless 😉
Hey Jenny 🙂 great recipe , can’t wait to try it. Just wondering does it matter what brands of ingredients we use ? As I live in Australia and don’t have the brands you used. Hopefully I don’t look to stupid
Wowwwww seriously I am drooling! They are looking awesome. Amazing recipe!
You are just evil-evil with these Oreos…whoa. I love them.
These bars look amazing! I love that you keep making wonderful desserts in the last month of your pregnancy… Keep them coming!
Pinning this! My little ones will love to make it for FHE tonight!
Oh. My. I’m bookmarking this one to reserve when I need to butter up my guy. He’d go gaga for these (and I, of course, would have to test one or two or three to make sure they’re up to par).
This might be the perfect bar!
All of my favorite things in a bar!! I’ll take a dozen 🙂
my hubby would faint. these look incredible!
Love these bars!
I can’t see how people wouldn’t go bonkers over these. They look marvelous!
My kids would think they had died and gone to heaven if I served them these for an after school snack. Fun, Jenny!
Oh My Goodness Gracious!!! Everything is so right with these bars, Jenny. Everything.
Does this recipe use hazelnut or vanilla extract? The ingredient line up picture includes imitation hazelnut extract, but you use vanilla extract in the action shot. Also, the ingredient list includes vanilla extract. It seems like it should be vanilla, but I want to make sure. Thanks!
Where did you find the Guittard chocolate chips? I love using them but usually I have to get bags from a baker friend who gets them straight from the supplier.
These look great! I’d like to try them with Biscoff spread instead of peanut butter…up the cookie factor a little! 😉
you’ve got me hooked on baking with oreos! These sound wonderful as usual 🙂
I love Oreo’s so I just know I would love this recipe.
I’m almost drooling on my keyboard here. That’s almost too much to take on a monday morning. I’m gonna be craving these the whole day. 🙂
I just want to have 6 of everything you post! Always.
Cant go wrong with PB, butter, chocolate chips, Oreos – Oh Jenny, so many great things rolled up into one. Delish!
