The peanut butter cookie bars are soft and chewy with lots of chocolate chips. These bars are perfect alongside a glass of cold milk!
Peanut butter cookies are one of my favourites and I find myself baking them quite often. Sometimes I do not have lots of time so I make cookie bars instead. These chocolate chip and peanut butter cookie bars are so good and you end up with 35 cookies in one batch!
What Are Bar Cookies?
Bar cookies are basically just cookies that are not individually shaped and baked. Instead, the dough is pressed into a baking sheet or dish and baked as a big slab. Once finished baking, the cookie slab is cut into individual bars.
I love bar cookies because not only are they easy to make, the recipe can be baked in one batch since it is a slab. Typically, cookie recipes need to be baked in a couple batches slowing down the process.
Bar cookies are also quite soft and chewy, almost soft like a dense brownie but being a cookie instead. They are awesome!
Ingredients You Will Need
Since these are essentially peanut butter cookies pressed into a baking sheet and cut into bars, the ingredients needed are typical for any classic peanut butter cookie.
- Peanut butter
- White sugar
- Brown sugar
- Baking powder
- Baking soda
- Chocolate chips
Beat The Wet Ingredients
I find that any time I bake cookies, I prefer to mix together the wet ingredients and dry ingredients separately. Then, they can be beat together which helps to ensure the cookie dough is smooth and creamy.
Start off by creaming the softened butter, peanut butter, white sugar and brown sugar. Once it is all smooth and creamy, mix in the eggs and vanilla.
Sift The Dry Ingredients
Dump all the flour, baking soda, baking powder, and salt in a separate bowl and sift them all together. This ensures that everything is evenly dispersed.
After the wet and dry ingredients have been combined separately, it is time to mix them together. Use an electric mixer to beat the dry into the wet. Peanut butter cookie dough is a little bit on the dry side, so the dough should look a little crumbly after everything has been combined. Finally, beat in the chocolate chips!
Press The Dough
Take the dough and press it into a cookie sheet. It is important to make sure that the dough is as even of a layer as possible to ensure even and consistent baking. This is now ready to go into the oven for baking!
How Long To Bake Cookie Bars?
Bake the cookie bars in a 375F oven. Depending on the size of the cookie sheet, the baking time will vary.
- 20-22 minutes for a 15×10 inch cookie sheet
- 17-19 minutes for a 17×11 inch cookie sheet
As the cookies bake you should notice that the edges begin to brown and crisp up. Once the baking has finished, take the cookie sheet out of the oven and place on a wire rack to cool. After the cookie slab has had a chance to slightly cool down, you can cut it into bars. I cut it into 35 bars, but you can cut them into whatever size you prefer!
