Ingredients for Grapefruit Lemon Loaf Cake
Here’s what you’ll need to make this delicious Grapefruit Lemon Loaf Cake:
2 pink grapefruits (zest) – The zest of the grapefruits will infuse the cake with a fresh, citrusy aroma and flavor.
100 ml pink grapefruit juice – Freshly squeezed juice enhances the cake’s moisture and adds vibrant flavor.
100 ml soy milk – This dairy-free option works perfectly as a base to create a wonderful vegan buttermilk.
190 g golden caster sugar – This fine sugar dissolves easily, giving the cake its sweet and tender texture.
120 g vegan Greek-style yogurt – This ingredient adds creaminess and moisture while maintaining a vegan alternative.
100 ml olive oil – A healthy fat that keeps the cake rich and moist without overpowering flavors.
1 teaspoon vanilla extract – A hint of vanilla perfectly complements the tart citrus flavors.
300 g all-purpose flour – Sifted flour is essential for a light and airy loaf.
1 tablespoon baking powder – This leavening agent is key for achieving that lovely rise.
¼ teaspoon sea salt – A pinch of salt will enhance all the cake’s flavors beautifully.
150 g powdered sugar – Sweet and smooth, this is perfect for glazing the loaf after baking.
1 tablespoon grapefruit juice – A small amount adds brightness to the glaze.
1 tablespoon vegan Greek-style yogurt – Using yogurt here helps create a creamy glaze that ties everything together.
How to Make Grapefruit Lemon Loaf Cake
Follow these simple steps to prepare this delicious Grapefruit Lemon Loaf Cake:
Step 1: Preheat the Oven
Preheat your oven to fan-forced 160°C (320°F) or conventional 180°C (356°F). Lightly grease an 8″ loaf tin, and don’t forget to line it with parchment paper for easy removal.
Step 2: Prepare the Vegan Buttermilk
In a jug, combine the freshly squeezed grapefruit juice and soy milk. Stir them together and let the mixture sit for about 10 minutes—this will curdle the milk slightly and create a vegan buttermilk that thickens the batter wonderfully.
Step 3: Mix the Zest and Sugar
In a large mixing bowl, add the grapefruit zest and sugar. Using your fingertips, rub the zest into the sugar until it feels wet and aromatic. It’s like an olfactory hug every time you mix it.
Step 4: Combine the Wet Ingredients
Add the vegan Greek yogurt, olive oil, and vanilla extract to the bowl. Whisk everything together until smooth. Then, pour in your vegan buttermilk mixture and whisk again until well blended.
Step 5: Fold in the Dry Ingredients
Sift in the flour, baking powder, and salt in two parts. Using a rubber spatula, gently fold the dry ingredients into the wet ingredients until just combined—you want to avoid overmixing, so no visible lumps of flour should remain.
Step 6: Bake It
Pour the batter into the prepared loaf pan. For a fun touch, use thin strips of vegan butter or a knife dipped in olive oil down the center of the loaf. Bake on the middle shelf for 50-60 minutes. Check for doneness by inserting a knife or toothpick; it should emerge clean.
Ensure you let the loaf cool in the pan for about 10 minutes before transferring it to a cooling rack—this ensures it keeps its shape wonderfully.
To finish, whisk together the powdered sugar, grapefruit juice, and yogurt until the glaze is smooth. Once your cake has cooled down, pour this zesty glaze on top and enjoy the delightful show of flavors that results from every bite. You’ll be left with a beautifully moist and fragrant loaf that’s perfect for sharing or savoring solo. Enjoy your Grapefruit Lemon Loaf Cake adventure—it’s a flavorful journey worth taking!
