Banana unit

one banana unit
two banana unit
three banana unit
four.

my guess is each unit is one, but you may need more...

(unit jokes likely to follow)

thought that as I typed it lol. One doesn't sound like enough though for a dozen muffins ( I know I know, size does matter too!) lol

What are the other measurements in the recipe? Are any of the others units?

The other measurements might be a clue.

Compare your recipe to other similar recipes. If the flour, liquids and sugar measurements are about the same as yours, go with the amount of bananas in the other comparable recipe.

here is the list of ingredients:
Ingredients
Banana Chocolate Chip Muffins
1 cup white All Purpose flour
1 cup whole wheat flour
1/2 cup rolled oats
2 teaspoons ground cinnamon
2 teaspoons baking powder
1 teaspoon baking soda
1/2 teaspoon salt
1 unit ripe banana, mashed
1/4 cup chopped walnuts
1/2 cup light brown sugar
2 tablespoons vegetable oil
2 large organic eggs
1 1/4 cups reduced-fat buttermilk
1 teaspoon pure vanilla extract
2 tablespoons chocolate chips

Here is one that is fairly similar to yours. The total grains and liquids are about equal. This one uses 3 mashed bananas.

I'm wondering if by unit, your recipe means 1 cup of mashed banana which would probably equal 3 bananas.

Banana Oatmeal Muffins

Yield: One dozen regular size muffins or six Texas size muffins and two regular size
Prep Time: 30 minutes
Cooking Time: 20-25 minutes

1 cup rolled oats
1 1/2 cups whole wheat flour
1/2 cup pastry flour
2 tsp baking powder
1/2 tsp baking soda
3/4 tsp salt
1 tsp cinnamon
1/2 tsp nutmeg
1/4 tsp cardamom (optional)
2/3 cup brown sugar, packed
3 tbsp butter, melted or use grapeseed oil
3 ripe to overripe bananas, roasted** and mashed
1/3 cup milk (soy, almond, skim, 1%, 2% or whole)
1 tsp vanilla
1 cup plain yogurt (full or low fat, not no fat)
1 egg

1. Preheat oven to 400°F. Line muffin tins with paper liners or grease very well.
2. Combine oats, flours, baking soda and powder, salt, spices and sugar in medium sized bowl.
3. In separate large bowl, combine melted butter, mashed roasted bananas, milk, vanilla, yogurt and egg. Stir to combine very well.
4. Stir dry ingredients into wet very gently and JUST until incorporated. Do not overmix!
5. Spoon evenly into 12 regular sized muffin tins or 6 Texas sized muffin tins and two regular. Bake for 20-25 minutes. Muffins are done when golden brown on top and a toothpick inserted into the center comes out clean.
6. Allow to cool in tins for 10 minutes, then turn out onto cooling rack and cool completely.

** To roast bananas: Place skin on bananas on a baking tray (lined with foil if you don’t want a sticky mess!) and pop into a 400°F oven for 15-20 minutes. You’ll know they are done when a) the bananas have turned black or b) your house smells like banana caramel. Remove from oven and allow to cool slightly before using.

that sounds about right too thanks so much I will give it a try with 3!
