Preheat oven to 350°F. Coat a 9-by-5 loaf pan with cooking spray.
In a mixing bowl, sift together the flour, baking soda, salt and cinnamon; set aside. In another bowl, mash the bananas until smooth.
In the bowl of a stand mixer, cream together the butter and sugar for 3 to 5 minutes at medium speed, or until fluffy. With the mixer still on medium speed, add in the eggs one at a time, then the vanilla, sour cream and mashed banana, mixing until fully incorporated. Turn the mixer off and add the flour mixture; beat on low speed until just combined (don’t over-mix). With a spatula or large spoon, gently fold in the dehydrated strawberries, chocolate chips, rainbow sprinkles, and walnuts.
Pour the batter into the prepared loaf pan; top with maraschino cherries and more sprinkles, then bake in the oven for 1 hour, or until an inserted toothpick comes out cleanly.
Let loaf cool 5 min in the pan; remove, then cool on a rack 10 to 15 min more. Slice and serve topped with a drizzle of caramel sauce, whipped cream, and more sprinkles… Enjoy!
