Lemon Rhubarb Tube Cake


  • 3 medium lemons
  • 1 cup butter, softened
  • 2 cups sugar
  • 3 large eggs, room temperature
  • 3 cups all-purpose flour
  • 1 teaspoon baking powder
  • 1/2 teaspoon baking soda
  • 1/2 teaspoon salt
  • 1 cup buttermilk
  • 1 cup sugar
  • 1 cup sliced fresh or frozen rhubarb
  • 1 cup halved fresh strawberries
  • Confectioners’ sugar, optional


  • Preheat oven to 350°. Grease and flour a 10-in. fluted tube pan. Finely grate enough zest from lemons to measure 2 tablespoons. Cut lemons crosswise in half; squeeze juice from lemons.
  • In a large bowl, cream butter and sugar until light and fluffy. Add eggs, one at a time, beating well after each addition. Beat in lemon juice and zest. In another bowl, whisk flour, baking powder, baking soda and salt; add to creamed mixture alternately with buttermilk, beating well after each addition.
  • Transfer batter to prepared pan. Bake until a toothpick inserted in the center comes out clean, 50-60 minutes. Cool in pan 10 minutes before removing to a wire rack to cool.
  • Meanwhile, for topping, combine sugar and rhubarb in a small saucepan. Bring to a boil; reduce heat. Simmer until rhubarb is almost tender, 8-10 minutes. Add halved strawberries; cook until strawberries and rhubarb are softened. Serve with cake. If desired, dust with confectioners’ sugar.

Test Kitchen Tip

  • Try replacing the strawberries with chopped apples for a uniquely different flavor twist!

    This dessert practically screams summer. The fresh lemon flavor in the cake and the tart rhubarb topping are just so refreshing. —Courtney Stultz, Weir, Kansas
