Peanut Butter Pretzel Brownies

Brownie Base
I cheated and used two packages of fudge brownie mix, though any doubled brownie recipe would work

Peanut Butter Filling
5 tbsp melted butter
1/2 cup powdered sugar
1 tsp vanilla
pinch of salt
3/4 c peanut butter

Topping
1 c crushed pretzels
1/2 c chocolate chips or chunk chocolate

Prepare brownie base and spread evenly in an 8x12 greased pan (can go smaller or bigger, depends the depth of the brownie you desire). Mix all filling ingredients together and dollop on top of brownie mix. se a knife to cut through and create a marbling effect. Sprinkle crushed pretzels and chocolate chips on top. Bake at 325 for approx. 40 minutes. Cool and slice. :)
