Smores banana bars

Vegan, gluten-free, and dang delicious. These bars have it all, and they NEED to be added to your baking rotation. I love to whip up a batch of these and enjoy them as a super filling breakfast with coffee, or as a snack throughout the day! They’re delightfully sweet and make an excellent dessert option as well.

These delicious bars take just 4 ingredients, have no oil or added sugar, and taste like s’mores and banana bread all at once. If you want to make these healthier, feel free to omit the chocolate/marshmallows all together and just make PB Banana Oat Bars, or give them a fun twist by adding dried fruit instead! Either way, these are easy, quick, and killer as a breakfast, snack, dessert, anything!
