Ingredients

Crumble Topping

  • ½ cup flour
  • ½ cup cornmeal
  • ¼ cup sugar
  • 2 Tablespoons brown sugar
  • ½ teaspoon baking powder
  • ¼ teaspoon salt
  • 3 Tablespoons butter chilled
  • 1 whole egg lightly beaten

Cake

  • ½ cup butter room temperature
  • 1 cup flour
  • 5 cups rhubarb can substitute up to two cups with another fruit
  • ¼ teaspoon ground ginger
  • 1 teaspoon ground cinnamon
  • ¾ cup sugar
  • 1 ⅓ cup cornmeal
  • 2 teaspoons baking powder
  • 1 teaspoon salt
  • 1 cup buttermilk
  • ½ cup yogurt or sour cream
  • 4 large eggs added one at a time

Instructions

To Make the Crumb Topping

  • Whisk the sugar, cornmeal, flour, baking powder, and salt thoroughly in a medium bowl and set aside.
  • Using your fingers, a fork or a pastry cutter, work in butter pieces until the crumbs are the size of small peas.
  • Using a fork, stir in the whisked egg until the mixture comes together. Cover and chill. This can be made up to 3 days in advance.

To Make the Cake

  • Preheat oven to 350°F. Lightly butter and flour a 13×9 baking dish or two loaf pans.
  • Toss the rhubarb (and optional fruit), ginger, cinnamon, and 1⁄4 cup of granulated sugar in a medium bowl and set aside while preparing other ingredients.
  • Whisk cornmeal, baking powder, salt, and 1 cup of flour in a medium-sized bowl, and set the flour mixture aside.
  • Whisk buttermilk and yogurt (or sour cream) in a smaller bowl and set aside.
  • Using a mixer with a whisk attachment, beat the remaining sugars and 1⁄2 cup butter until light and fluffy. 
  • To the butter and sugar mixture, add eggs, one at a time, beating well between additions.
  • Reduce speed to low and slowly add dry ingredients, alternating with milk mixture, beginning and ending with dry ingredients.
  • Fold in rhubarb mixture. Spread the batter into the prepared pan and sprinkle the crumble topping liberally over the cake batter.
  • Bake the cake until golden brown and a toothpick inserted into the center comes out clean, about 1 hour. 
  • Transfer to a wire rack and let cool slightly before serving.
