Ingredients

Rhubarb Topping

  • 3 cups sliced fresh rhubarb (½-inch slices)
  • 1 cup sugar
  • 2 tablespoons all-purpose flour
  • ½ teaspoon cinnamon
  • ¼ teaspoon ground nutmeg
  • ¼ cup butter melted

Cake Batter

  • ¼ cup butter melted
  • ¾ cup sugar
  • 1 large egg
  • cups all-purpose flour
  • 2 teaspoons baking powder
  • ½ teaspoon ground cinnamon
  • ¼ teaspoon nutmeg
  • ¼ teaspoon salt
  • cup whole milk
  • sweetened whipped cream or whipped topping optional

Instructions

  • Preheat oven to 350 degrees F. Coat the bottom and sides of a 10-inch springform pan generously with nonstick cooking spray.
  • Scatter the sliced rhubarb over the bottom of the prepared pan. Combine 1 cup sugar, 2 tablespoons flour, ½ teaspoon cinnamon and ¼ teaspoon nutmeg in a small bowl and sprinkle it over the rhubarb. Drizzle ¼ cup melted butter over the top and set it aside.
  • For the batter, in a large bowl, beat ¼ cup melted butter and ¾ cup sugar until blended. Beat in the egg. In a separate bowl, combine the flour, baking powder, cinnamon, nutmeg and salt. Add about half of the dry mixture to the egg mixture and beat just until combined. Add half of the milk and beat again until combined. Repeat with remaining flour mixture and milk, beating well. Spoon the cake batter over the rhubarb mixture and use an offset spatula or the back of a spoon to spread out evenly.
  • Bake for 40 to 45 minutes or until golden brown and a toothpick inserted in the center comes out clean. Remove from oven and run a knife along the edge of the cake and the pan to loosen the edges and then immediately invert onto a serving dish. Unlatch and remove the sides of the springform pan. Use a knife to lift up the base of the pan and remove it.
  • Allow to cool for about 10 to 15 minutes and then slice and serve warm with whipped cream, if desired.

Notes

Rhubarb should be trimmed by about 1-inch at each end. Trim and discard green leaves. Wash well and slice into ½-inch slices.
