We had a busy, busy weekend full of Halloween parties and I made these delicious peanut butter chocolate chip bars to take to one Saturday evening.

These bars are fantastic, just like our turtle cookie bars or cranberry crumb bars, they are always the first sweet to be devoured at parties. You just can’t go wrong with pairing the flavors of PB and chocolate, am I right?

Step by step

Whisk together flour, salt, and baking soda in a bowl and set aside. In a stand mixer (affiliate link) or large bowl with an electric mixer, mix brown sugar, peanut butter, butter, and sugar until smooth.
Add egg and vanilla extract to the peanut butter mixture and mix on medium speed until just combined. Reduce mixer speed to low and add in flour mixture.
Remove from mixer and fold in chocolate and peanut butter chips by hand. Spread the cookie dough batter in the pan and bake 25 to 30 minutes until golden and center is done.
Cool on a rack and slice into 16 bars once cool.

Tips for best results

You can use either crunchy peanut butter or smooth peanut butter but do not use natural versions, the end result won’t be the right texture due to the separation of oil. Other nut butters will work too as long at they don’t have oil that separates.
Choose any kind of chocolate chip you want, dark chocolate, semisweet, milk chocolate, even white chocolate chips: it’s up to you, they will all turn out delicious!
For thicker bars use a 9 by 9-inch baking dish and extend the baking time by about five minutes.

Freeze bars in a freezer bag, separating layers with parchment paper. Thaw at room temperature or in the refrigerator overnight.
