Ingredients
Scale
- 2 cups (250g) all-purpose flour
- 2 tablespoons poppy seeds
- 1 teaspoon baking powder
- ½ teaspoon baking soda
- ¼ teaspoon salt
- ¾ cup (170g) unsalted butter, softened
- 1½ cups (300g) granulated sugar
- 3 large eggs, room temperature
- 2 tablespoons grapefruit zest (from about 2 medium grapefruits)
- ½ cup (120ml) fresh grapefruit juice
- ½ cup (120ml) buttermilk, room temperature
- 1 teaspoon vanilla extract
Instructions
- Step 1: Prepare Your Ingredients and Equipment Preheat your oven to 350°F (175°C) and grease a 10-cup bundt pan thoroughly, ensuring you reach all the crevices. In a medium bowl, whisk together the flour, poppy seeds, baking powder, baking soda, and salt. Set aside. In a separate small bowl, combine the grapefruit juice, buttermilk, and vanilla extract.
- Step 2: Create the Grapefruit-Infused Batter In a large mixing bowl, cream the butter and sugar together until light and fluffy, about 3-4 minutes. Don’t rush this step—proper creaming incorporates air that helps your Grapefruit Poppy Seed Cake rise beautifully. Add the grapefruit zest and mix until fragrant. Add eggs one at a time, beating well after each addition and scraping down the bowl as needed.
- Step 3: Combine Wet and Dry Ingredients With the mixer on low speed, add the flour mixture in three additions, alternating with the grapefruit-buttermilk mixture, beginning and ending with the flour. Mix until just combined—overmixing will develop the gluten and result in a tougher cake. The batter should be smooth and have a medium consistency that drops from the spoon rather than pours.
- Step 4: Bake to Perfection Pour the batter into your prepared bundt pan, smoothing the top with a spatula. Tap the pan gently on the counter a few times to release any trapped air bubbles. Bake for 45-50 minutes, or until a toothpick inserted in the center comes out clean and the cake begins to pull away from the sides of the pan.
- Step 5: Glaze and Serve Allow your Grapefruit Poppy Seed Cake to cool in the pan for 15 minutes before inverting onto a wire rack to cool completely. While the cake cools, prepare the glaze by whisking together the powdered sugar, grapefruit juice, and zest until smooth. Adjust the consistency as needed—it should be thick enough to coat the back of a spoon but thin enough to drizzle. Once the cake is completely cool, drizzle with the glaze, allowing it to cascade down the sides.
