Ingredients & Substitutions

Ingredients needed to make peanut butter banana bars.

Mashed Banana: This is about 3 large bananas. Since bananas vary in size, be sure to measure or the bars might end up too wet or too dry.
Honey: To make these vegan, use maple syrup or packed brown sugar.
Milk: Any type of dairy or dairy-free milk will work. You can even use water in a pinch.
Seeds: If you omit the seeds, use an additional 1/4 cup of oats so the bars are not too wet.
Chocolate Chips: Feel free to switch up the add-ins. Use 3/4 cup total of chocolate chips, chopped nuts, dried fruits (dates, cranberries, etc.), or a combination.

Recipe Serving Suggestions

These bars are a very complete breakfast, snack, or dessert on their own, but they also pair well with savory dishes. Here are some ideas:

Expert Tips & Variations

Use a kitchen scale. This is the easiest and more precise way to measure ingredients when baking. You also do not have to dirty a bunch of measuring cups.
Use parchment paper. This will prevent the bars from sticking and allow you to easily remove them from the pan and slice.
Let cool completely. These bars are very soft. If you try to remove them before they cool, they will fall apart. They will continue to firm up and set as they cool in the pan.
Freeze leftovers. These freeze extremely well. I recommend wrapping each bar in plastic wrap then foil first. Place all of the wrapped bars into a freezer bag and store for up to 3 months. Microwave from frozen to thaw and serve warm.
