Step 1

Preheat an oven to 350 degrees F and grease a bread pan (not a large pan - see note).

Step 2

In a medium bowl, whisk together the flour, baking soda, baking powder, cream of tartar, and salt. Set aside.

Step 3

In the bowl of a mixer, add the canola oil and sugar.

Step 4

Add the egg and mix again.

Step 5

Dump in the zucchini and mix on medium speed until everything is evenly combined.

Step 6

Starting and ending with the flour, add a little flour while the mixer is running on low.

Step 7

Next add a little mashed banana and continue to alternate until the last of the flour is added.

Step 8

Pour into a greased bread pan and top generously with cinnamon sugar. *See note below for instructions to make muffins.

Step 9

Bake at 350 degrees F for 50-55 minutes, tenting with foil the last 15 minutes to avoid too much browning.

Step 10

Allow to cool before slicing, then serve warmed up with a little butter.
