  • Total Time: 50 minutes
  • Yield: 8 servings

Ingredients

Cake Ingredients

  • 1 ½ cups all-purpose flour
  • 1 cup granulated sugar
  • ½ cup unsalted butter, softened
  • 2 large eggs
  • ½ cup grapefruit juice
  • 1 tablespoon grapefruit zest
  • 2 tablespoons poppy seeds
  • 1 teaspoon baking powder
  • ½ teaspoon baking soda
  • ¼ teaspoon salt
  • 1 teaspoon vanilla extract

Instructions

  1. Preheat Oven: Begin by preheating your oven to 350°F (175°C). Grease and flour an 8-inch round cake pan to prevent sticking.
  2. Mix Dry Ingredients: In a medium bowl, whisk together the all-purpose flour, baking powder, baking soda, salt, and poppy seeds until evenly combined.
  3. Cream Butter and Sugar: In a large bowl, use a mixer to cream the softened unsalted butter and granulated sugar until the mixture is light, fluffy, and pale in color.
  4. Add Eggs: Beat in the eggs one at a time, making sure each egg is fully incorporated into the butter and sugar mixture before adding the next.
  5. Incorporate Wet Ingredients: Stir in the grapefruit juice, grapefruit zest, and vanilla extract until the mixture is smooth and well combined.
  6. Combine Dry and Wet Mixtures: Gradually add the dry ingredients to the wet mixture, stirring gently until just combined to avoid overmixing the batter.
  7. Pour Batter into Pan: Transfer the batter to the prepared cake pan and smooth the top evenly using a spatula.
  8. Bake: Place the cake pan in the preheated oven and bake for 35 minutes, or until a toothpick inserted into the center comes out clean.
  9. Cool the Cake: Remove the cake from the oven and let it cool in the pan for 20 minutes before transferring it to a wire rack to cool completely.
  10. Frost (Optional): Once completely cooled, you can frost the cake with a light glaze made from powdered sugar and grapefruit juice for added sweetness, or enjoy the cake plain for a lighter treat.

Notes

  • For a gluten-free version, substitute all-purpose flour with a gluten-free baking flour blend.
  • Ensure the butter is softened to room temperature for easier creaming.
  • Do not overmix the batter after adding the dry ingredients to keep the cake tender.
  • The optional glaze adds extra citrus flavor but can be omitted to reduce sugar content.
  • Use fresh grapefruit juice and zest for the best flavor intensity.
  • The cake pairs wonderfully with a cup of tea or light coffee.
