The Inspiration.
This recipe for chocolate peanut butter swirl bars is inspired and brought to you by my very own mom, Sandra. Whenever I think of these bars, I’m always taken back to mom’s kitchen.

My mom is truly an inspiration as a cook and a mom. Not a day passed that mom didn’t have breakfast, lunch, or supper, including any sort of snacks or desserts for all of us.
I can’t even begin to imagine the number of meals (and dishes!) that have been made in that kitchen.
Mom has always prided herself in being able to whip up a meal or a quick dessert in a matter of minutes. These bars are just one example of a recipe ready in minutes.

The Masterpiece.
With quick prep and bake time, the Swirl Bars are perfect if you’re crunched for time after work or rushing off to church potluck, and will definitely be a win with any chocolate and peanut butter fans!
To begin these scrumptious bars, I first cream together the butter and both types of sugars.
If you’re looking for a good arm workout, I highly recommend mixing the butter and sugars together by hand!
However, if you’re looking to speed up this process, any sort of mixer works great. Personally, I use a Kitchen Aid stand mixer. I think that machine has to got to be one of the greatest time savers in the kitchen ever invented!

Once the peanut butter oatmeal crust is baked, these bars come together so quickly!
After sprinkling the chocolate chips over the warm crust, the peanut butter mixture can be prepared.
You’ll be able to tell when the chocolate chips are ready to be spread over the crust when they appear glossy/shiny or if you just touch them and they’re melty!
The peanut butter can be spread over the top and swirled in any direction then after spreading the chocolate evenly over the crust.
And there you have it! The bars are ready to be enjoyed at this point!

Growing up, and even to this day, these are my all-time FAVORITE bars!
Between the moist peanut butter and oatmeal crust to the perfect balance of melted dark chocolate and peanut butter on top, the chocolate swirl bars are a great match for anybody with a sweet tooth!
