Reese’s: My favorite candy.
Peanut Butter: Makes everything better.
Oatmeal: Â Now it’s healthy!
Cookie Bars:Â Easy to eat, easy to make.
Do you see where this is going? I’ve been on a bar kick lately that started with my Raspberry Coconut Magic Bars and then more recently the Coconut Toffee Chocolate Chip Cookie Bars. I thought I’d mix it up a little today and bring my favorite candy EVER to the table – Reese’s Peanut Butter Cups. I pulled out all the stops today with Reese’s miniatures AND minis and also used Reese’s peanut butter baking chips in the dough.
Oh. And don’t think that these are “peanut butter” bars exclusively due to the Reese’s. No. There is peanut butter in this recipe as well. Not only are these bars delicious but they are really filling as well. The center is perfectly soft and chewy and of course the sweet Reese’s surprise makes it even more drool-worthy. Now I’m wondering why I sent that big plate of them to work with Chris…
This is one of those desserts that you can whip together in no time and that will have everyone asking for the recipe. Trust me. To make sure the Reese’s are nicely distributed I put down a layer of dough first and then sprinkle the yumminess on top. Next some dollops of the remaining dough top it off making a peanut butter oatmeal cookie sandwich with a Reese’s filling. Not a bad way to go I’m thinking.
They bake up so beautifully and I love seeing the Reese’s peeking out from the bars! I cut these into 16 bars for the pictures but you’ll want to cut these in half for a party. If you’re by yourself and no one is there to judge…eat a whole bar. You deserve it. I know I did!
Tips for the perfect bars
- Let your butter come to room temperature, an hour or two is usually perfect. This helps the creaming process go smoothly.
- Spoon and level the flour or else you’ll end up with too much and the bars could end up a little dry.
- I used old fashioned oats in this recipe but quick oats will also work in pinch.

How To Make Reese’s Peanut Butter Oatmeal Bars
Reese’s Peanut Butter Oatmeal Cookie Bars
Ingredients
- 1 1/2 sticks unsalted butter softened
- 2 cups light brown sugar
- 1/2 cup creamy peanut butter
- 2 eggs room temperature
- 1 tbsp vanilla
- 2 cups flour
- 1 cup old fashioned oats
- 2 1/2 tsp baking powder
- 1/4 tsp salt
- 1 cup Reese's peanut butter baking chips
- 2 cups Reese's minatures chopped or Reese's minis
Instructions
- Preheat oven to 350 degrees.
- Line a 9x13 inch baking dish with parchment paper.
- Cream butter and sugar together in a large mixing bowl. Add peanut butter and continue mixing.
- Add eggs one at a time, mixing well after each egg. Add in vanilla.
- Combine flour, oats, baking powder, and salt in a small mixing bowl.
- Add the flour mixture slowly stirring until well combined.
- Stir in the peanut butter chips.
- Spread 2/3 of the dough on the bottom of the pan. Top with Reese's minis or chopped miniatures.
- Drop the remaining dough on top by the teaspoon. It doesn't have to be perfect and it won't cover all the Reese's.
- Bake for about 30 minutes. Let cool completely and then cut into bars.

I used Nestle chocolate and peanut butter chips and a mix of mini peanut cups and leftover Reese’s peanut butter eggs because that’s what I had hanging around my pantry! Soooo excited about these!
Trish - Mom On Timeout says
Woohoo! I bet they turned out amazing!

When I look for recipes on line, I always read the reviews. It is so annoying to read so many comments that say how good the picture looks. Of course they look great! I can see that. Lets give comments after you make them. Valid comments that can help others decide if they are worth making. Obviously you have lots of time on your hands!
Kelley says
Stacy Myers, thanks for your great comments. You get it!
carrots says
So agree with you!! Tell us how they taste!! Thanks!!
Stacy Myers says
These are so yummy! I used white wheat flour and sucanat instead of brown sugar. I didn’t have the Reese chips, so I used chocolate chips and chocolate chunks. The entire family raved over these….and they are fantastic warm, with a little bit of vanilla ice cream. 🙂

Margo, Thrift at Home says
looks great! Could I omit the peanut butter chips in the dough without affecting the chemistry? Seems like I could. . .
Trish - Mom On Timeout says
You can just replace the pb chips with chocolate chips if you’d like Margo!
Tanesha says
I cooked these for Christmas any mine were dry. What could I do different? Add more butter?
Trish - Mom On Timeout says
They might have been over baked Tanesha. I would shave off a few minutes next time. Good luck!
