Instructions

  9. Sprinkle streusel evenly over the cake batter.
  10. Bake for 40-45 minutes or until a toothpick inserted into the center comes out clean.
  11. Allow cake to cool in pan for 15 minutes before transferring to a wire rack to cool completely.

Notes

For a nutty twist, sprinkle chopped walnuts or pecans over the streusel topping before baking.
