  5. Pour the batter into the prepared baking pan and sprinkle the crumbs on top. Gently press the crumbs into the batter to help stick.

  7. Allow to cool for about 30 minutes prior to serving. If desired top with icing.

Notes

  • If you don't have buttermilk on hand you can make sour milk. Add 2 teaspoons of lemon juice or plain white vinegar to your measuring cup, then pour the milk in to reach 2/3 cup. Let it sit briefly. This will make sour milk.
  • If you want to make this in a 9x13 pan you can add an additional 1/2 cup flour and 1/3 cup milk to the recipe. Double the crumb recipe and bake for 40 minutes.
