Adapted from Little Spoon Farm for our low-iodine diet with regular diet substitutions. Still an amazing muffin, they do not last in the kitchen. PS I am not a dietitian or a dr. These are just my experiences, please consult your dr if on a low iodine diet.

A delightful sourdough discard banana muffin recipe featuring wheat germ (instead of nuts) and loaded with ripe bananas! You’ll appreciate how soft these are, with a touch of crispness on top from the addition of bakers’ molasses (Low iodine option). They’re perfect for making ahead for busy mornings!

Sourdough Discard Banana Wheat Germ Muffins
Wet Ingredients
- 8 tablespoons (113 g) Kentucky Lard, Or unsalted butter melted
- 3/4 cup (150 g) Organic White Sugar
- 1/4 cup Unsulfered bakers’ molasses(50 grams) (sub 200 grams of brown sugar for the white sugar and molasses if you are not low iodine)
- 3 Large egg whites, (or 2 large eggs if not restricted)
- 3 (350 g) very ripe bananas about 1 cup, mashed – the bananas were about the length of my hand and weighed the 350 grams
- 1 teaspoon (5 g) vanilla extract (measure with Love)
- 1 cup of Sourdough discard, new or saved about 250 grams
Dry Ingredients
- 3/4 cups (180g) Organic all-purpose flour ( I like Bob’s Redmill or Sir Galahad Non GMO Milled in USA non Bromated)
- 1/4 Cup (60g) Organic Wheat Flour
- 2 teaspoons baking powder
- ½ teaspoon baking soda
- 1 teaspoon (5 g) Kosher salt
- 2 tablespoons Organic Pure Ceylon Cinnamon (measure to taste I love Cinnamon)
- 1 cup (75 g) Organic Wheat Germ
Directions
- Preheat oven to 350°F (176°C) lightly grease a 12-count muffin tin or use a liner of your choice. (mine made a baker’s dozen)
- Whisk dry ingredients: the 2 flours, wheat germ, cinnamon, salt, baking powder, and baking soda together in a bowl and put it aside.
- Utilize a different bowl for wet ingredients, use a fork to squash the bananas until smooth.
- Melt the lard or butter in a mixing bowl or use a pan on the stove let it cool a bit.
- Add remaining Wet ingredients to mashed banana: the egg whites, cooled lard, sourdough discard, and vanilla extract and mix until combined.
- Add the wet ingredients to the dry ingredients and mix until just combined. (Do not over mix!) It will be thick.
- Bake for 20-25 minutes (check at 15min) or until a toothpick inserted into the center comes out clean. Transfer to cooling rack. When cool they pop right out of the tin if it is greased 🙂
I hope the Sourdough discard muffins turn out great, let me know in the comments how it goes!
