For the best streusel, ensure butter is cold straight from the fridge — pop it in the freezer for 10 minutes while you prep the filling. Don't overbake; the center should still wobble slightly when you pull it. The crisp keeps for 4 days in the fridge; reheat at 350°F for 10 minutes to re-crisp the topping. To freeze: assemble unbaked in a foil pan, wrap tightly, and bake from frozen, adding 20 minutes to the bake time. For gluten-free, use a 1:1 gluten-free flour blend and certified GF oats. For dairy-free, substitute full-fat coconut milk for evaporated milk and use vegan butter.
