Spray a bread pan (not a large bread pan, but a slightly smaller bread pan.) and set aside.
In a medium bowl, whisk together the baking soda, cream of tartar, flour, salt and cinnamon.
3/4 teaspoon Baking Soda, 1 1/2 teaspoons Cream of Tartar, 1 3/4 Cup Flour, 1/2 teaspoon Salt, 1/4 teaspoon Cinnamon
Set aside.
Cream together the softened butter and sugar.
1/3 Cup Butter, 2/3 Cup Sugar
Add the eggs and mix until smooth.
2 Large Eggs
In a glass measuring cup, smash the bananas.
1 Cup Bananas
Add a little flour to the egg mixture and turn on the mixer.
Cream everything together as the flour gets incorporated add a little banana.
Continue to alternate between the dry ingredients and banana, ending with the banana.
Stir in the cinnamon chips and place in the bread pan.
1 Cup Cinnamon Chips
Sprinkle with 2 tablespoons of the cinnamon sugar and bake for 50-60 minutes. Sometimes I tent with foil the last 15 minutes if its getting too brown.
3 Tablespoons Cinnamon Sugar for topping
Remove from the oven and sprinkle with the last tablespoon of cinnamon sugar, allow to cool before slicing for nice slices, or dig in while it's warm but it may be a little more crumbly hot.
