Preheat oven to 350 degrees and grease a 9×13 pan.
Combine pretzels, brown sugar, and melted butter and press into prepared baking dish and bake for 10 minutes.
Dissolve the Jello in the boiling water, stirring for 2 minutes or until Jello is completely dissolved and then stir in the strawberries and chill. Refrigerate until partially set. If it is not set enough it will leak through your cream cheese layer and make your pretzels soggy.
Beat cream cheese and sugar until smooth. Fold in cool whip or fresh whipped cream. Spread over cooled crust make sure you spread completely to the edges to create a seal so your jello doesn’t leak through. Pour jello over cream cheese layer. Refrigerate until serving.
