Perfectly thick, soft and chewy peanut butter bars with a peanut butter and chocolate glaze.
You wont see me use the words “BEST” in too many recipes, because a lot of people have great variations of a lot of dishes. However, without hesitation I can say these are THE BEST peanut butter bars in existence!
This peanut butter bars recipe has been a huge family favorite for many years. Simply put, they are completely addicting and you will want to eat the entire pan by yourself. Consider that my warning 🙂
If I’m ever making these for a party I always have to make an extra pan for my family or else I’m in trouble! I’ve tried quite a few peanut butter bars in my day, and none compare to these.
First of all, they are thick, chewy, and soft. They’re in the same family as my Oatmeal Chocolate Chip Cookie Bars, but with a peanut butter twist. I love the taste and texture that the oats add.
They have the perfect ratio of chocolate and peanut butter, without being overwhelmingly sweet.
The dough for the bars has 1/2 cup of peanut butter in it. Once they’re baked and cooled, you spread a very thin layer of creamy peanut butter over them.
Then, you make a warm chocolate frosting and pour it over the top. YUM!
These really are the World’s Best Peanut Butter Bars!

Ingredients
For the bars:
- 3/4 cup butter
- 1/2 cup granulated sugar
- 1 cup light brown sugar
- 2 large eggs
- 1/2 teaspoon vanilla extract
- 1/2 cup creamy peanut butter (plus more for spreading over baked bars)
- 2 1/2 teaspoons baking soda
- 1/2 teaspoon salt
- 1 1/2 cups all-purpose flour
- 2 cups old-fashioned rolled oats
For the chocolate frosting:
- 1/4 cup butter
- 1 Tablespoon unsweetened cocoa powder
- 1 1/2 Tablespoons milk
- 1 1/4 cups powdered sugar
- 1 teaspoon vanilla extract
Instructions
- Preheat oven to 350 degrees F. In a large mixing bowl, cream together the butter, sugar and brown sugar.

- In a separate bowl mix together the dry ingredients. Add dry ingredients to creamy mixture.
- Press firmly into a greased 9x13'' pan. Bake at 350 degrees for 17-21 minutes. Do not over-bake! They will look just barely set in the center, and they will harden as they cool. Allow to cool completely.
- Once cooled, spread a thin layer of peanut butter over the bars.
To make the chocolate frosting:
- Add butter to a small skillet over medium heat. Once melted, stir in cocoa.
- Remove from heat and add milk, powdered sugar and vanilla. Whisk until smooth, using electric beaters to get out any lumps, if needed. .
- Spread chocolate frosting over the top of the bars.

Your ‘best ever’ peanut butter bars were mushy on the bottom and had way too much peanut butter. The peanut butter, along with the salt called for in the recipe, gave these bars a very salty taste. There was way too little icing to really taste the sweetness! A very big disappointment!

These are indeed the best peanut butter bars ever! I follow the recipe exactly and they are perfect every time, and devoured by all. People always ask me for the recipe. The edges are chewy and the middle is soft. Perfect!

Not traditional pb squares. More cake like. Did not care for them at all.
