Grandma’s Rhubarb Cake (but healthier)

There's nothing like grandma's baking, and this Rhubarb Cake recipe is adapted from a family classic. Made with fresh rhubarb, ripe bananas, coconut sugar, buttermilk, olive oil, and cinnamon, resulting in a tender, moist crumb. It is sweet, tart, nostalgic, easy to make, and perfect served with Greek yogurt, ice cream, or a hot cup of coffee.
