Chocolate Peanut Butter Cookie Bars
Peanut Butter Oatmeal Cookie Bars with a Creamy Chocolate Frosting. A chocolate peanut butter lover’s dream!
We have an annual tradition to head up to a cabin with friends. We love it because we are surrounded by great friends, eat amazing food, and always laugh a lot! It is so nice to go to the woods and get away from technology and just spend good quality time with family and friends. One of our favorite things to do there is EAT! We take our menu planning pretty seriously and there is never a shortage of treats.
My dear friend, Stephanie, always brings up her famous chocolate peanut butter bars and they are a huge hit! She doubles the recipe and brings a huge pan of them and we just eat slivers of the bars all day long. If you eat little pieces all day long, there is less guilt! 🙂 But after the first year at the cabin I told her that I needed the recipe stat.
These Chocolate Peanut Butter Cookie Bars are a soft, chewy homemade peanut butter oatmeal cookie baked until soft. Â Then the peanut butter finger bars are topped with a fluffy peanut butter glaze and a creamy milk chocolate frosting. The peanut butter cookie pairs perfectly with the light chocolate frosting.
How to make Chocolate Frosted Peanut Butter Cookie Bars:
- Â Cream together butter, sugars, vanilla, eggs, and peanut butter until light and fluffy. Use regular or crunchy peanut butter in this recipe. I wouldn’t suggest using natural peanut butter as it won’t be sweet enough.
- Stir in quick oats, flour, baking soda, and salt just until mixed. Spread in a 9 x 13 pan and bake until cooked through but still soft and chewy.
- Whip remaining peanut butter until light and fluffy — about 4 minutes. Spread on slightly cooled cookie.
- Make the chocolate frosting. This can be made in a saucepan. Melt the butter and add milk and cocoa. Carefully spread over the peanut butter layer. Cool completely and slice into bars.

Love this recipe so much! So easy to make and the ratio of pb to chocolate is heavenly.
This recipe is delicious! The oats give it a fantastic texture. It almost has a toasted coconut texture without the coconut taste. I always add about 10 min to the cooking time. The recipe is forgiving- if you over bake it tastes great and likewise with under baking. I made this at Thanksgiving and it disappeared quickly. My picky daughter loves it. These bars are one of my favorites and are used heavily in my rotation.
This ended up being excellent, but it does not look like the pictures. Maybe I over-creamed the cookie dough – I’m not sure – but the dough seemeed more moist than it should be, and even though I cooked it fo the full 15 minutes at 350, it stayed kind of moist and dough=y. It firmed up as it cooled off, and it tasted great, but I don’t think it was as cookie-like as it was supposed to be.
Also, I felt more “on my own” with this recipe compared with others I’ve baked on this site (and LOVED them!). No video, and very little instructions. Is it salted or unsalted butter? Should the butter be softened, frozen and shaved, etc.? I’m thinking I’ll stick it in the refrigerator after spreading the peanut butter next time, so the peanut butter firms up before I apply the warm icing (when I did it it threatened to mix together completely).
Regardless, I will be trying this one again and hopefully it will turn out even better!
