For an extra layer of flavor, consider adding a teaspoon of lemon zest to the cake batter. If you don't have buttermilk, you can make a substitute by adding 1 1/2 teaspoons of white vinegar or lemon juice to 1/2 cup of milk. Let it stand for 5 minutes before using. The crumble topping can be made ahead of time and stored in the refrigerator for up to 2 days. This will help the butter solidify, resulting in even larger, more distinct crumbs. Store leftover crumb cake in an airtight container at room temperature for up to 3 days.
