Grapefruit Cake with Pistachios is a one-bowl quick bread with a mild citrusy flavour and crunchy pistachios. It’s dairy-free and vegan, and made with wholesome ingredients, so you can even enjoy a slice or two for breakfast!


  • 1 1/2 cups whole wheat flour
  • 3/4 cup cane sugar
  • 1 teaspoon baking soda
  • 1/2 teaspoon salt
  • 1 cup unsweetened nut milk
  • 1/4 cup extra virgin olive oil
  • 1/2 red or pink grapefruit, juiced and zested
  • 1/2 cup raw whole pistachios
  • 1 tablespoon crushed raw pistachios


  1. Preheat oven to 350F. Grease and line a loaf pan with parchment paper.
  2. In a large bowl, whisk together the flour, sugar, baking soda and salt.
  3. Add in the milk, oil and grapefruit juice and zest. Stir until the dry ingredients are well incorporated.
  4. Fold in the 1/2 cup of whole pistachios.
  5. Pour batter into the prepared loaf pan and sprinkle the crushed pistachios on top.
  6. Bake for about 48-52 minutes, or until a toothpick inserted into the cake comes out clean.
  7. Let cool for a few minutes in the pan before transferring to a wire rack to cool completely.
  8. Store in an airtight container at room temperature and enjoy within 4-5 days.


  1. This cake was baked in a loaf pan measuring 8.5″ x 4.5″. If your loaf pan is a little bigger, you may need to reduce the bake time by a few minutes. Test for doneness with a toothpick
  2. Make sure you zest the grapefruit first before you cut and juice it. Once juiced, it’s more difficult to zest the rind of a grapefruit.
  3. Be sure to read the Tips and Substitutions section above for more detailed advice and suggestions for variations on the recipe.
