Notes

  • Fresh rhubarb works best in this rhubarb batter cake.  Frozen rhubarb will fall apart during baking. It still tastes great, but the consistency is different.
  • This is a magic rhubarb cake because boiling water is poured over a sugar mixture right before baking.  It forms the most delicious crunchy sugar topping.
    • Add just enough boiling water so that all the sugar mixture is moistened. This takes approximately 1/2 cup.
  • For a new spin, add some ground cinnamon to the sugar topping.
