  • This is a very dry batter so don’t worry that it doesn’t look like cake batter, as the rhubarb will start to “melt” during baking and release steam to help make it lovely and moist.
  • Try adding variations like, lemon zest, orange zest, vanilla, ginger, or adding almond, hazelnut, pecan, walnut or coconut to the streusel.
  • Great served warm with a thick custard, ice cream, rhubarb compote, or simply dusted with icing sugar.
  • Wonderful for breakfast with a cup of coffee!
