Calling all Rhubarb Lovers! This luscious coffee cake is an irresistible way to start the day…or end it! Any day you can have cake for Breakfast is a good day! I’ve been dying to make this moist flavor packed crumb cake for months. The crumb is the “Non-icing” on top of the cake! If you’re not a Rhubarb lover…add a different fruit! This cake is so out of the this world crazy good not to try it!
