Ingredients

(Tip: You can find the complete list of ingredients and their measurements in the recipe card below.)

All-purpose flour provides structure to the cake while keeping the texture soft and tender.

Granulated sugar sweetens the batter and balances the tartness of the grapefruit.

Poppy seeds add subtle crunch and a classic visual element to the cake.

Baking powder helps the cake rise and ensures a light texture.

Salt enhances the flavors and balances the sweetness.

Eggs provide structure, moisture, and richness to the batter.

Vegetable oil keeps the cake moist and tender.

Fresh grapefruit juice delivers bright citrus flavor and natural acidity.

Grapefruit zest intensifies the citrus aroma and adds depth to the flavor.

Greek yogurt adds moisture and contributes to a soft, delicate crumb.

Vanilla extract adds warmth and complements the citrus notes.

Powdered sugar forms the base of the simple glaze that finishes the cake.

Directions

Preheat the oven to 350°F (175°C). Lightly grease a loaf pan or line it with parchment paper for easy removal.

In a large bowl, whisk together flour, poppy seeds, baking powder, and salt.

In another mixing bowl, beat the eggs and granulated sugar until the mixture becomes light and slightly thickened. Add vegetable oil, grapefruit juice, grapefruit zest, Greek yogurt, and vanilla extract. Mix until smooth.

Gradually add the dry ingredients to the wet mixture, stirring gently until just combined. Avoid overmixing, as this can affect the cake’s texture.

Pour the batter into the prepared loaf pan and smooth the top with a spatula.

Bake for about 45–50 minutes, or until a toothpick inserted in the center comes out clean. Allow the cake to cool in the pan for about 10 minutes before transferring it to a wire rack.

While the cake cools, prepare the glaze by mixing powdered sugar with a small amount of grapefruit juice until smooth.

Once the cake has cooled completely, drizzle the glaze over the top. Allow the glaze to set before slicing and serving.

Variations and Customizations

This citrus cake can easily be adapted with other fruits or flavor combinations. For example, lemon or orange juice can replace grapefruit if you prefer a milder citrus flavor. I once tried using blood orange juice, which created a slightly sweeter cake with a beautiful color.

If you enjoy extra texture, consider adding chopped pistachios or almonds to the batter. These nuts complement the citrus flavor and provide additional crunch.

For a richer version, substitute part of the vegetable oil with melted butter. This adds deeper flavor while maintaining a moist crumb.

You can also enhance the glaze by adding a small amount of honey or vanilla extract. This introduces additional depth and sweetness.

Finally, for a more intense citrus profile, brush the warm cake with a light grapefruit syrup before applying the glaze.
