Making These Chocolate Chip Banana Bars in Advance
These chocolate chip banana bars can be made in advance! They can be stored in an airtight container at room temperature for a few days, in the fridge for up to a week, or in the freezer for up to a month.
Just be sure to separate them a bit and place parchment between each layer of bars! This will help prevent them from sticking to each other if they’re stacked.
Doubling This Recipe
This recipe can also be doubled and made in a quarter sheet pan (9″x 13″). Bake for 37-42 minutes, or until the edges look golden brown and the center looks set.
Baking These Bars in a Different Type of Pan:
These bars bake up best in a light-colored metal pan.
However, if you need to bake these bars in a glass baking pan, reduce the baking temperature by 25 degrees (to 325 F) and bake them for about 5 minutes less. Glass doesn’t heat up as quickly as metal but becomes very hot once heated up.
