1 cup finely crushed pretzels (do it in a food processor)
8 tablespoons melted butter
1/4 C sugar
1/4 teaspoon cinnamon (optional)
Blend ingredients thoroughly. Press firmly into an 8″ or 9″ pie plate and bake at 375 for 7-10 minutes. Use with banana cream pie, pecan pie, chocolate cream pie or anything else that would be good with a salty, pretzely crunch.
