Gooey Chocolate Peanut Butter Oatmeal Bars
Packed with chocolate, oatmeal, and peanut butter chips, these cookie bars have a gooey center that tastes fresh from the oven every time.

Oatmeal Peanut Butter Chocolate Chip Bars Recipe
The edges will have a traditional cookie consistency, but the center is ultra gooey when warm and tastes fresh of out the oven chewy once completely cooled.
Melted butter helps create the slightly underdone gooeyness along with generous amounts of chocolate in every bite. The balance of chocolate, peanut butter and oatmeal make these the perfect bar cookie!
A friend from our workout class at the Y shared that her family looks forward to making these rich bar cookies every year at Christmas. When I heard the genuine enthusiasm in her voice I had to ask for the recipe!

We have the regulars of Almond Bark Candy, Magic Bars, White and Milk Chocolate Chip Cookies and our Cherry Candy recipe, and will be making this one a new addition to our tradition.
Ingredients Needed
- Butter – unsalted
- Creamy Peanut Butter
- Eggs
- Light Brown Sugar
- Vanilla Extract
- All-Purpose Flour
- Old Fashioned Rolled Oats
- Baking Soda
- Salt
- Chocolate Chips
- Peanut Butter Chips

Step By Step Instructions
Preheat oven to 350℉ and prepare a 9 x 13″ baking dish by lining with parchment paper or coating with non-stick cooking spray.
Melt butter and then stir in peanut butter, eggs, brown sugar and vanilla. We truly do use a full tablespoon, instead of the traditional teaspoon of pure vanilla.


Stir in the flour, oats, baking soda and salt until just combined.
Add chocolate chips and peanut butter chips.


Spread evenly in the prepared baking dish. Bake for 20 to 25 minutes. 22 minutes was the perfect amount of time for us with multiple tests in our convection oven.
Then center should be set and the edges lightly golden.

Serve warm (with napkins) or completely cooled for a different, but amazing eating experience each time.
Recipe Tips and Tricks
- Using real butter and melting it helps contribute to the gooey texture.
- We typically have chocolate chips on hand, but this is a great recipe to use chocolate chunks in.
- Use a board scraper to easily cut straight lines in the pan.
- We try to cut small bars and freeze extras for Valentine’s Day or another celebration.
