Rhubarb Cake from Orpha Ilstrup
This Rhubarb Cake recipe, written in 1991 by Orpha Ilstrup, is a charming example of Midwestern baking that showcases the tart, fresh flavor of rhubarb. Moist and tender with a hint of vanilla and cinnamon, this cake balances sweet and tangy beautifully. The batter is simple and pantry-friendly, while the cinnamon-sugar topping adds warmth and crunch. Perfect for summer gatherings or as a cozy treat with coffee, it reflects a time when neighbors shared recipes on handwritten cards and rhubarb thrived in backyard gardens.

Tips

  • Use fresh, bright red rhubarb for the best color and flavor
  • Margarine or butter both work, but butter adds richer flavor
  • Toss rhubarb lightly in flour to prevent sinking
  • Add chopped walnuts or pecans for texture
  • Serve warm with whipped cream or vanilla ice cream
  • Reduce sugar slightly if your rhubarb is mild
  • Add orange zest for a citrus note
