Mix together all the wet ingredients. Mash the bananas first if you'd like. I threw it all into my mini stand mixer.
3 banana, ½ cup butter, 1 tsp vanilla extract, 2 egg
Stir together all the dry ingredients.
1 cup sugar, 2 cup flour, 1 tsp baking powder, ½ tsp baking soda, ½ tsp cinnamon
Add the dry ingredients into the wet and mix to combine.
Fold in the chips. I don't think I used enough chips. Feel free to increase the amount.
¼ cup cinnamon chips
Spray your slow cooker with baking spray and pour the mixture in. I ran out of baking spray and pretty much sprayed out air. I think that's another reason why my edges burned.
Place a paper towel under the lid to help absorb moisture. Remove the paper towel during the last half hour of cooking.
