- 1 3/4 cup white whole wheat flour (or all-purpose flour – see notes)
- 1 tsp baking powder
- 1/2 tsp sea salt

How to Make Easy Grapefruit Olive Oil Cake
Step 1: Preheat the Oven
Heat your oven to 350°F. Greasing your pan well ensures the cake comes out perfectly every time. Using parchment paper at the bottom makes it even easier to remove once cooled.
Step 2: Prepare the Zest and Juice
Zest enough grapefruit to yield about 2 tablespoons. Be careful not to include too much of the bitter white pith. Then juice your grapefruits until you have one full cup of juice—this usually takes about one and a half grapefruits.
Step 3: Combine Dry Ingredients
In a medium bowl, sift together the flour, baking powder, and sea salt. Stir in the grapefruit zest so that it’s evenly distributed throughout the flour mixture. This step helps ensure that your cake rises perfectly!
Step 4: Whisk Eggs and Sugar
In a large bowl, whisk together the eggs until they’re nice and frothy. Add in the granulated sugar and vanilla extract, whisking until everything is light and fluffy. This creates air pockets in your batter that will help make your cake delightfully airy.
Step 5: Mix Wet and Dry Ingredients
Slowly alternate adding in your dry flour mixture and grapefruit mixtures into the egg mixture while continuing to whisk gently until just mixed. Be careful not to overmix; we want our cake to be tender!
Step 6: Bake Your Cake
Pour the batter into your prepared pan and bake for 50-60 minutes. To check if it’s done, insert a toothpick into the center—if it comes out clean, it’s ready!
Step 7: Cool and Serve
Once baked, remove from the oven and let cool slightly before inverting onto a serving platter. If you like, sprinkle with powdered sugar for an extra special touch and serve with fresh grapefruit sections on the side.

Pro Tips for Making Easy Grapefruit Olive Oil Cake
Baking can be a delightful adventure, and with a few pro tips, your grapefruit olive oil cake will turn out perfectly every time!
- Use fresh ingredients: Freshly squeezed grapefruit juice and zest add vibrant flavor that enhances the cake’s overall taste. Bottled juices often lack the brightness you want in this dessert.
- Measure flour correctly: Spoon the flour into your measuring cup and level it off instead of scooping directly from the bag. This prevents packing and ensures you have the right amount, leading to a better texture.
- Don’t overmix the batter: Mix until just combined when adding the flour mixture to the wet ingredients. Overmixing can lead to a dense cake rather than a light and fluffy one.
- Test for doneness: Ovens can vary, so start checking your cake around the 50-minute mark. A toothpick inserted in the center should come out clean or with a few crumbs attached, indicating it’s ready.
- Cool completely before serving: Allowing the cake to cool fully helps set its structure, making it easier to slice without crumbling. Plus, it allows flavors to develop further!
How to Serve Easy Grapefruit Olive Oil Cake
This cake is not only delicious but also versatile! You can serve it in various ways, whether for breakfast, brunch, or dessert. Here are some ideas to elevate your serving experience.

- Fresh mint leaves: A sprig of mint brings a refreshing pop of color and fragrance that complements grapefruit beautifully.
- Citrus segments: Adding fresh grapefruit sections on top or alongside provides an extra burst of tartness that pairs well with the cake’s sweetness.
Side Dishes
- Greek-style yogurt: A dollop of dairy-free yogurt can add creamy richness and balance the sweetness of the cake, making it perfect for breakfast or dessert.
- Fruit salad: A medley of seasonal fruits adds freshness and color to your table while complementing the citrus notes of the cake.
- Herbed quinoa salad: A light quinoa salad tossed with fresh herbs offers a savory contrast that helps round out a meal if you’re serving this cake as part of brunch.
