Baking Options:

  • All the batter can be baked in a 8” x 4” loaf pan that has been buttered and lined with parchment paper so that the paper over hangs the long edges. This will make it easier to remove. Place the batter into the prepared pan and spread evenly with an offset spatula. Cover with the streusel topping.
  • Bake in the middle of the oven for 45-50 minutes. After 45 minutes start testing to see if the bread is done by inserting a skewer into the center of the cake. If it comes out clean it’s done. If not let the bread cook for another 5 minutes and test again.
  • You can also evenly divide the batter between 6 mini loaves in a Trudeau Silicone Mini Loaf Pan that has been lightly coated with butter. Divide the streusel topping evenly over the 6 loaves. Bake in the middle of the oven for 23-25 minutes or until the top of the loaves spring back with lightly pressed.
  • The batter can also be divided evenly amongst a 12 count standard muffin pan, lined with cupcake liners. Divide the streusel topping amongst the 12 muffins. Bake at for 18-20 minutes. or until the top of the muffins spring back when lightly pressed.
