You only need 12 simple ingredients to make these banana cookie bars.
unsalted butter: Unsalted butter works well in baking by providing a fat, and flavor without added salt. You can use salted butter in it’s place if you would like.
brown sugar: brown sugar is a mixture of granulated sugar and molasses. Light brown sugar and dark brown sugar are interchangeable. However dark brown sugar is sweeter than light brown sugar.
vanilla extract: Vanilla extract not only adds a slight hint of vanilla flavor, it also increases the other flavors in recipes.
eggs: When baking with eggs I recommend always using room temperature eggs.
all-purpose flour: No need to sift the flour for this recipe, but sifted flour would make your bars lighter and less dense.
kosher salt: kosher salt is a course more crystallized salt from table salt. This gives the salt more flavor.
bananas: This recipe is best with bananas that are soft and ripe. Look for bananas that are speckled. Or you can follow my tips below to ripen them at home.
Applesauce: Use 1/4 cup of applesauce in place of eggs, if you want a lower fat recipe.
Table Salt: If you are using table salt in place of kosher salt, reduce your salt to 3/4 teaspoon.
