Ingredient Notes
Here are some notes on the ingredients. For a full list of ingredients, check out the recipe card below.
- Unsalted butter- Pull this out 2 hours before baking so the butter is softened.
- Brown sugar- I used light brown sugar.
- Peanut butter- Use Jif or skippy peanut butter. I like to use creamy peanut butter, but you can use crunchy if you prefer. I don't recommend using natural peanut butter, because it will be too runny for this recipe.
- Egg- Pull this large egg out 2 hours before baking so it is room temperature.
- Chocolate chips- You semi-sweet chocolate chips, dark chocolate chips, or mini chocolate chips. I don't recommend milk chocolate chips because it will be too sweet.

Step By Step Instructions
Here is how to make and bake these cookie bars. This recipe uses a stand mixer with a paddle attachment or a hand mixer (electric mixer). It also uses an 8X8-inch baking dish.
STEP 1: Mix the dry ingredients. In a medium bowl, mix the all-purpose flour, baking soda, and salt. Use a food processor to lightly blend the cookies. They should be small and medium pieces.
STEP 2: Beat butter and sugars. In a large bowl, beat the butter, brown sugar, and sugar on high speed for 2 minutes until creamy.
STEP 3: Add wet ingredients. Then, add in peanut butter and vanilla extract and mix until combined. Add the egg and mix in on medium speed. Make sure to scrape the sides of the bowl with a rubber spatula.
STEP 4: Add flour mixture. Add this in on low speed until just combined. Then, add in chocolate chips and chopped Nutter Butters.
STEP 5: Press cookie dough. Press the cookie dough into the square pan, making sure to press into the corners.
STEP 6: Bake. Bake for 20-25 minutes until the edges are golden. It is really easy to underbake these and have middle be gooey. Make sure to bake until the middle is set.
Top the bars immediately with more chopped Nutter Butters and chocolate chips. Cool the bars completely on a cooling rack before removing out of the pan.
Expert Baking Tips
- Flour- Make sure the flour is spooned and leveled. If you stick the measuring cup directly into the flour, it will compact the flour. Compacted flour can cause the cookies to be dry.
- The cookie bars should be slightly underdone, because they will continue to cook as they cool. This helps to make sure they have chewy centers.
- You can top these bars with whole Nutter Butters, but it goes make it hard to cut into it.
- To easily remove to peanut buttery bars, spray the pan with baking nonstick spray. Line the bottom of the pan and 2 sides with parchment paper and spray again. Once they are done cooling, you can easily remove from the pan.
