Preheat oven to 400˚F. Mix together crushed pretzels, chopped pecans, brown sugar, and melted butter.
Spread on a large baking sheet with sides (I used my jelly roll pan) and bake at 400˚F for 7 minutes. Allow the mixture to cool, and then break it into small pieces. Set aside.
Beat together softened cream cheese, granulated sugar, and vanilla.
Fold in the cool whip. Cover and store in the fridge.
Before serving, stir the diced strawberries and sugared pretzels and pecans into the cream cheese mixture.
