For the Cake:
- ¾ cup extra virgin olive oil
- ½ cup Greek-style yogurt (non-dairy if needed)
- 2 tablespoons poppyseeds
- ¼ cup grapefruit juice (from about ½ large grapefruit)
- ¾ cup unsweetened almond milk or soy milk
- 1 cup organic raw sugar
- 1–2 tablespoons grapefruit zest (optional)
- 1 tablespoon vanilla extract
- 2 cups all-purpose flour
- 2 teaspoons baking powder
- ½ teaspoon baking soda
- 1 teaspoon kosher salt
For the Icing:
- ¾ cup powdered sugar
- 1 tablespoon grapefruit juice
- 1 tablespoon cranberry juice (for color; can be substituted with more grapefruit juice)
For Optional Topping:
- Candied ginger
- Dried culinary-grade rose petals
- Preheat and Prepare: Preheat your oven to 350°F (175°C). Lightly oil a standard loaf pan (8.5 x 4.5 x 2.5 inches) or line it with parchment paper to prevent sticking.
- Mix Wet Ingredients: In a large bowl, combine the extra virgin olive oil, Greek-style yogurt, poppyseeds, grapefruit juice, unsweetened almond or soy milk, organic raw sugar, grapefruit zest (if using), and vanilla extract. Stir until thoroughly mixed.
- Combine Dry Ingredients: In a separate smaller bowl, whisk together the all-purpose flour, baking powder, baking soda, and kosher salt to evenly distribute the leavening agents.
- Combine Wet and Dry: Carefully fold the dry ingredients into the wet mixture. Mix gently to ensure all flour is hydrated but avoid overmixing to keep the cake tender and light.
- Bake the Cake: Pour the batter into the prepared loaf pan. Bake in the preheated oven for about 1 hour. Test doneness by inserting a knife into the center; it should come out clean without sticky crumbs.
- Cool the Cake: Allow the cake to cool completely in the pan before removing it to a wire rack or serving plate to prevent breakage.
- Prepare the Glaze: While the cake cools, whisk together the powdered sugar, grapefruit juice, and cranberry juice in a small bowl until smooth.
- Glaze and Garnish: Drizzle the glaze evenly over the cooled loaf. Optionally, sprinkle candied ginger and dried rose petals on top to add visual appeal and extra flavor notes.
- Store Properly: Cover the cake and keep it at room temperature. It will stay fresh for up to 5 days on the counter.
Notes
- Using a glass loaf pan may increase baking time due to slower heat conduction and will cause the cake to continue cooking after removal from the oven. Check doneness accordingly.
- If using an aluminum loaf pan, start checking for doneness at 45 minutes to avoid overbaking.
- Non-dairy yogurt and milk substitutions make this recipe suitable for those avoiding dairy.
- Grapefruit zest is optional but enhances citrus aroma and flavor.
