Lisa, streusel toppings freeze impressively well. Sometimes we even make an extra batch of streusel topping to freeze separately so that we can have some on hand for the next time we're ready to bake. You can either top the pie with the struesel topping and then freeze, or you can freeze it in a separate container and top it when you're ready to bake — either method works. Happy baking! Kye@KAF
