All about Peanut Butter Blondies

Sometimes you just can’t get enough peanut butter.  You have it on toast or make peanut butter and jelly sandwiches but you still keep craving it.  You then find yourself getting spoonfuls of peanut butter from the jar.  If this sounds like you, and you’re a peanut butter lover too, this is the cookie bar for you!   

The blondie is an all-time great base recipe and you can pretty much add anything to make it your own.  We have tried so many different additions and they have been nothing but delicious.  But this peanut butter blondie is down right amazing, you get all the rich and fudgy flavors of the blondie with a hint of a peanut butter cookie.  

The best way to make this recipe is to start off with melted butter.  We’ve tried using softened butter before, but it does not give it the fudgy, rich center.  

In a large bowl or a mixing bowl, combine the wet ingredients and then add in the dry ingredients.  You can either use parchment paper, aluminum foil or a baking dish sprayed with cooking oil.  You then will add in the blondie batter and bake for about 20-25 minutes.  You will need to let the blondies completely cool before slicing.
