Roasted Banana and Black Walnut Bundt Cake #BundtBakers

Our theme this month for Bundt Bakers was Any combination of fruit and nuts, but at least one of each! Our host, SimplyVeggies, created this fun, challenging theme for us!

My inspiration for this theme came from my daughter, who loves Banana Boats.  We made them on vacation and I loved the banana taste and texture after roasting in the oven.  I also always like to look for ways to cut down on oil and fat in my cakes, so I worked hard to incorporate healthy fats into the batter and I think I have a winner!

  • 1 1/2 t cinnamon
  • 1/2 t salt
