Peanut Butter Chocolate Bars
Peanut Butter Chocolate Bars are similar to blondies, but these bar cookies have peanut butter chips and chocolate through the center of the bars. Easy dessert for any time you want a little sweet treat. These also pack up well and often my go-to treats to send in the mail.

Peanut Butter Chocolate Bars
Chocolate and peanut butter. They are mean’t to be together, you know that. I’ve paired them up before; Chocolate cupcakes with peanut butter frosting, chocolate sugar free peanut butter eggs, a late night snack of a spoonful of peanut butter topped with a few chocolate chips – uhh, yes, please and thank you!
These dense chewy bars aren’t overly sweet. There is just enough flavor from the peanut butter chips and swirl of chocolate. Perfect with a glass of milk or a warm cup of coffee or tea.
These are the bars I would send to my son during his first year in college. Right before summer break I would pack up a batch before finals. Definitely helps with taking tests, right?!
Why you should make these peanut butter cookie bars
- One pan easy recipe. No dropping or forming cookies in batches. All the batter is spread in one pan.
- Can be mailed easily. For the freshest delivery, wrap each bar in plastic wrap, then place in an air tight container. Add cushion like bubble wrap under, over and on the sides of the container.
- Not overly sweet. I cut the sweetener to just 1 1/2 cups from over 2 cups of sugar. The peanut butter chips and chocolate add more flavor, so you can taste all the flavors, not just the sugar. Want to lower the sugar even more? Use a sugar alternative like Lakanto monk fruit (affiliate).
Ingredients needed:
To make these cookies you need basic baking ingredients like butter, eggs, flour sugar and an leavening agent.
This recipe is a basic cookie base recipe laced with peanut butter, peanut butter chips for extra deliciousness, and swirled with some melted semi-sweet chocolate. I know, crazy good.
Most items will be stock pantry ingredients. However, you may need to pick up the following:
- Peanut butter baking chips – if you can’t find them, then pick up butterscotch baking chips.
- Chocolate chips – use your favorite chocolate chips. I always have milk chocolate on hand. However, dark or even a sugar free chocolate will work well in this recipe.
How To Make Cookie Bars
STEP 1: Cream Butter and Sugar
For these cookie bars you will whisk together the butter, peanut butter, sugars, eggs, and vanilla until light and fluffy.
STEP 2: Mix Dry Ingredients
Next, whisk together the dry ingredients and add to the sugar mixture.
STEP 3: Fold in Baking Chips
Fold in the peanut butter chips into the cookie bar batter.
STEP 4: Layer the Batter
The next step is what makes these cookie bars a little different. We layer the cookie dough. First, lightly spray a baking pan with non-stick cooking spray. Put half of the prepared cookie dough on the bottom of the pan spreading it evenly.
STEP 5: Melt the Chocolate Chips
Melt the chocolate chips in the microwave or double boiler, then drizzle the chocolate over the cookie dough. You may want to place the chocolate in a piping bag to distribute on the cookie dough.
For for a homemade piping bag, place the melted chocolate (cooled) in a small sandwich bag and snip one corner with scissors before drizzling over the cookie batter.
STEP 6: SWIRL Melted Chocolate
Finally, add the remaining cookie dough and spread over the chocolate layer. Take a sharp knife and swirl it through the batter to distribute the chocolate under the batter.
STEP 7: Bake
Bake in the oven at 350°F and cool before slicing!
Go make a batch of these bars and send them to someone special for no reason at all! Every bite gets a mmmm comment and hello… what’s not to like, darling duo; peanut butter and chocolate!
How to Store Peanut Butter Chocolate Bars
Keep these bars in an airtight container. This will remain fresh for up to two weeks.
How to freeze
Freeze for up to 6 months. To freeze, cool completely before placing the cookie bars in an air tight freezer container. If you are layering the bars, then place freezer paper or parchment paper between the layers.
I like to use hard containers for cookie bars instead of freezer bags so that the bars don’t get smashed by other foods in the freezer.

Needed a fun recipe this week and this is it! Perfect balance of peanut butter and chocolate!
I made a batch of these and took them to the lake this weekend — my family DEVOURED THEM! Such a great recipe!!
I don’t often review, but I found this recipe 3 months ago and I’ve made 8+ batches since. Every one loves these things! Two things I would note after several batches, is:
1) Do spoon your flour into your measuring cup. It is possible to measure too much flour by simply scooping.
2) I skip the step of melting the chocolate. I simply mix in the morsels and it still turns out stellar!
Thank you Bonnie for taking the time to comment. Your tip to #1 is spot on! I think people know this, but not everyone does, so I’ll add that tip in the notes. I’m all for saving an extra step (#2).
Love peanut butter and chocolate anything! These really sound delicious and what a nice treat! Great idea to send sugar for finals haha!
Yes! Who needs to order pizza when you have these bars to much on 🙂
Well. You know how I feel about these bars! I Loooove them. For real.
P.S. Your nails look great! What color is that?
Thanks, Heather! the bars are so good – thick cookie, brownie consistency. In a category of their own! I actually got a manicure, so thanks for noticing my nails. No clue on the color. I let them pick it for me 🙂
What a delicious package. I am sure your son was delighted to receive this brain-power treat. Wishing him good luck with all his finals.
Hi Norma! Yes, he always is happy to get a package in the mail with treats! Thanks you 🙂
