Finnish Brownies with Peanut Butter Frosting

I’m a definite fan of chocolate and peanut butter mixed together- I try to combine it whenever possible, and I’ve done that again with these Finnish Brownies with Peanut Butter Frosting! Chocolate by itself is amazing yes, but combining it with the flavor of peanut butter just makes your taste buds come alive with nutty goodness. These brownies are topped with chopped walnuts which add a decorative appeal, but also a wonderful crunch to the top.

My fiance is a huge brownie fan.  He has watched me make them several times now, and let me tell you- he never complains about eating them.  He can eat 2-3 brownies in one sitting if you leave him alone!
