For the cake

  • 11/2 cups flour
  • 2 teaspoons baking soda
  • 1 teaspoon kosher salt
  • 3 eggs
  • 2 5-ounce containers plain Greek yogurt
  • 1/2 cup canola oil
  • 1 cup granulated sugar
  • 1/4 teaspoon vanilla extract
  • Zest from one grapefruit
  • 1/2 cup freshly squeezed grapefruit juice

For the glaze

  • 2 tablespoons freshly squeezed grapefruit juice
  • 1 cup confectioners' sugar


  • :Preheat your oven to 350°F. Using cooking spray, grease a 10-inch tube pan. Using a stand mixer, mix the eggs, yogurt, sugar, vanilla, grapefruit juice and grapefruit zest.
  • In a separate bowl sift the flour, baking soda and salt. Add the dry ingredients to the wet ingredients and mix well. Next fold in the canola oil until incorporated.
  • Pour the batter into the prepared pan and bake for 50 minutes. Once baked, remove the pan from the oven and allow the cake to cool completely.
  • Next, remove it from the pan to a platter. Mix together the confectioner sugar and the 2 tablespoons of grapefruit juice. Drizzle the glaze over the cake and allow to set.


I peeled the zest off the grapefruit with a vegetable peeler instead of my microplane zester and finely minced it. I found the skin of the grapefruit to be tougher than lemons or limes.
Wait for the pound cake to completely cool before applying the grapefruit glaze. 
Refrigerate pound cake for a week in the fridge or freeze for later.
Make sure to cover the cake with foil or plastic wrap to prevent it from drying out.
