How to Make Easy Grapefruit Olive Oil Cake
Step 1: Prepare Your Baking Pan
Start by preheating your oven to 350°F. Greasing a 9-inch springform pan (or round can pan) with oil is essential to ensure your cake comes out easily once baked. Line the bottom with parchment paper for extra protection.
Step 2: Zest and Juice the Grapefruit
Zesting the grapefruit yields about two tablespoons of bright-colored zest, which infuses the cake with incredible flavor. Be careful to avoid the bitter white pith! After zesting, juice your grapefruits until you have one cup of fresh juice—this will keep your cake moist and flavorful.
Step 3: Combine Dry Ingredients
In a medium bowl, sift together the flour, baking powder, and sea salt. Stir in the grapefruit zest so it’s evenly distributed throughout the mixture. This step helps ensure that your dry ingredients are well-blended before adding them to the wet ingredients.
Step 4: Whisk Eggs and Sugar
In a large bowl, whisk three eggs until they are well combined. Gradually add granulated sugar along with vanilla extract or vanilla bean paste. The goal here is to whisk until the mixture becomes light and fluffy; this will help create air pockets in your cake, making it tender.
Step 5: Mix Wet Ingredients
Slowly whisk together the olive oil and freshly squeezed grapefruit juice into your egg mixture. This combination adds richness without being heavy, keeping your cake light yet flavorful.
Step 6: Combine Wet and Dry Mixtures
Now it’s time to combine everything! Alternately add small amounts of your dry flour mixture and grapefruit mixture into the egg mixture while whisking continuously until just mixed together. Overmixing can lead to a dense cake, so be gentle!
Step 7: Bake Your Cake
Pour your batter into the prepared pan and smooth out the top if needed. Bake in your preheated oven for about 50-60 minutes. You know it’s ready when a toothpick inserted into the center comes out clean—this part is always so exciting!
Step 8: Cool and Serve
Once baked, remove from the oven and let it cool in the pan for a bit before releasing it onto a serving platter. It’s optional but oh-so-lovely to sprinkle some powdered sugar on top before serving alongside fresh grapefruit sections!

Pro Tips for Making Easy Grapefruit Olive Oil Cake
Baking is an art, and a few tips can help you create the most delightful Easy Grapefruit Olive Oil Cake!
- Use fresh grapefruit: Freshly squeezed juice and zest provide a vibrant flavor that bottled options can’t match, ensuring your cake is bursting with citrus goodness.
- Don’t skip the parchment paper: Lining the bottom of your pan with parchment prevents sticking, making it easier to remove the cake once it’s baked. This way, you can present your masterpiece without any mishaps!
- Measure flour correctly: Spoon your flour into the measuring cup instead of scooping it directly from the bag. This helps avoid packing and results in a lighter cake texture.
- Check for doneness: Since ovens vary, keep an eye on your cake towards the end of baking. A toothpick should come out clean when inserted in the center, ensuring it’s perfectly baked without being dry.
- Let it cool completely: Allowing the cake to cool in the pan for a bit before transferring it to a platter helps maintain its structure and moisture, making each slice delicious.

Side Dishes
