Preheat oven to 350F. Grease a 9 x 5 loaf pan and set aside.
In a small bowl, mix flour, baking soda, and baking powder. Set aside.
In a mixing bowl, cream butter and sugars. Mix in eggs, vanilla, applesauce, and mashed bananas. Stir in chopped strawberries and cinnamon chips.
Add flour mixture into the wet ingredients and mix to combine.
Pour into greased loaf pan (top with strawberry slices and cinnamon chips, if desired) and bake for 60-65 minutes, until a toothpick inserted in the center comes out clean.
Cool for 10 minutes in the pan before removing and cooling fully on a wire rack. Slice and enjoy!
