Ingredients
- Ripe Bananas: Because of the natural sweetness of ripe bananas, no additional sweetener is needed for these peanut butter oatmeal bars - this means 3g of sugar per serving. The mixture of mashed banana and peanut butter binds the bars without additional fats or ingredients.
- Creamy Peanut Butter: Use processed, homemade, or natural peanut butter in this recipe. Swap it for almond butter, cashew butter, or sunflower seed butter if desired.
- Old-Fashioned Rolled Oats: Rolled oats have a thick, chewy texture ideal for this recipe. The oats soften once baked but retain their desirable chewiness.
- Semi-Sweet Chocolate Chips (or chunks): Peanut butter and banana naturally pair perfectly with chocolate. You can also use peanut butter or white chocolate chips.
