Method
 

Preparation Steps
  1. Preheat your oven to 350°F (175°C) and grease and flour an 8-inch round cake pan.
  2. In a medium bowl, whisk together the all-purpose flour, baking powder, baking soda, salt, and poppy seeds until well combined.
  3. In a large bowl, beat the softened unsalted butter and granulated sugar together until light and fluffy, about 3-5 minutes.
  4. Add the eggs one at a time, mixing well after each addition until fully incorporated.
  5. Pour in the grapefruit juice, grapefruit zest, and vanilla extract and stir until blended smoothly.
  6. Gradually fold in the dry ingredients until just combined without overmixing.
  7. Pour the batter into the prepared pan and bake for 30-35 minutes or until a toothpick comes out clean.
  8. Let the cake cool in the pan for about 20 minutes before transferring to a wire rack to cool completely.
  9. Optionally, frost with a glaze made from powdered sugar and grapefruit juice after cake is fully cooled.
