A dessert in three parts: crust, filling, and streusel topping
Whisk together the ingredients for the filling, pour over your pretzel crust
Combine ingredients for streusel, set aside.
Bake at 425 for 15 minutes, then lower the temperature to 350 for another 15-20 minutes. Remove from the oven, top with streusel, and bake another 10-15 minutes. Let it cool completely before eating.
*These proportions made much more dessert than I anticipated. You may want to consider halving the recipe. I filled a 5×7 baking dish and a 7.5×9 baking dish.
