For the cake:

  • 1-1/2 cups all-purpose flour

  • 2 teaspoons baking powder

  • 1/4 teaspoon salt

  • 3 large eggs, room temperature

  • 1 cup fat-free plain yogurt

  • 1/3 cup sugar

  • 5 tablespoons grated grapefruit zest

  • 1/4 cup agave nectar or honey

  • 1/2 teaspoon vanilla extract

  • 1/4 cup canola oil

For the glaze:

  • 1/2 cup confectioners' sugar

  • 2 to 3 teaspoons grapefruit juice

  • Grapefruit wheels and fresh mint leaves, optional

  • Fresh mint leaves


  1. Preheat oven to 350°. Whisk together flour, baking powder and salt. Combine next seven ingredients. Gradually stir flour mixture into yogurt mixture, then pour into a 9-in. round baking pan coated with cooking spray. Bake until a toothpick inserted in center of cake comes out clean, 25-30 minutes. Cool.

  2. For glaze, mix confectioners' sugar with enough grapefruit juice to reach desired consistency; drizzle glaze over top, allowing some to flow over sides. Top cake with grapefruit and mint if desired.

  3. Freeze option: Omit glaze. Securely wrap cooled cake in plastic and foil; freeze. To use, thaw at room temperature. Prepare glaze; top as directed.
