For a richer flavor, use brown butter in the streusel topping. If you don't have buttermilk, you can make a substitute by adding 1 tablespoon of lemon juice or white vinegar to a measuring cup and then filling it with milk to equal 1 cup. Let it sit for 5 minutes before using. The cake can be stored in an airtight container at room temperature for up to 3 days.
