The user experienced a toaster oven banana bread with an unusually crispy crust. This crispiness is likely due to the toaster oven's heating elements being closer to the bread. They are seeking to replicate this crispy crust effect in a standard oven. Previously, attempts at broiling resulted in burnt bread. The user is considering purchasing a large toaster oven for this purpose. They provided a mayonnaise banana bread recipe that might have been used. The recipe includes mashed bananas, brown sugar, mayonnaise, egg, and vanilla extract. Dry ingredients consist of flour, baking powder or soda, salt, and optional cinnamon. The method involves combining wet and dry ingredients with minimal mixing. The bread was originally baked at 350 degrees Fahrenheit in a loaf pan, but the specific oven issues led to using a toaster oven. The goal remains to achieve a crispy crust comparable to the toaster oven result.
