How to Make Easy Grapefruit Olive Oil Cake
Step 1: Preheat the Oven
Heat your oven to 350°F. Greasing a 9 springform pan with oil and lining the bottom with parchment paper ensures your cake will come out cleanly and beautifully.
Step 2: Zest and Juice the Grapefruit
Zest your grapefruit carefully until you have about 2 tablespoons. Remember to avoid the white pith since it’s bitter! Then juice enough grapefruits until you have one full cup. Combining these two elements adds that wonderful citrus punch.
Step 3: Prepare the Dry Ingredients
In a medium bowl, sift together your flour, baking powder, and sea salt. Mixing in the grapefruit zest at this stage helps distribute its flavor throughout the dry ingredients. Set aside this mixture for later.
Step 4: Whisk the Eggs
In a large bowl, whisk your eggs until they’re nice and frothy. Add in granulated sugar and vanilla extract (or paste) and keep whisking until everything looks light and fluffy. This step is key; it incorporates air into your eggs which helps give the cake its lovely texture.
Step 5: Combine Wet and Dry Ingredients
Now comes the fun part! Slowly alternate adding your dry mixture and grapefruit juice-oil mixture into the egg mixture while whisking just until combined. Be gentle here; we don’t want to overmix!
Step 6: Bake Your Cake
Pour your batter into the prepared pan and pop it into the oven. Bake for about 50-60 minutes or until a toothpick inserted comes out clean. The smell that fills your kitchen during baking is simply heavenly!
Step 7: Cool and Serve
Once done, remove from oven to cool slightly before inverting onto a serving platter. You can sprinkle powdered sugar on top if you’d like—a little touch that adds elegance! Serve with fresh grapefruit sections for an extra treat.
And there you have it! A delicious Easy Grapefruit Olive Oil Cake that’s sure to brighten up any day. Enjoy every slice!
Pro Tips for Making Easy Grapefruit Olive Oil Cake
Baking this delightful grapefruit olive oil cake is a breeze, and these tips will help ensure it turns out perfectly every time!
- Use fresh grapefruit: Freshly squeezed juice and zest enhance the flavor of your cake, bringing out the bright citrus notes that make this dessert stand out.
- Measure flour correctly: Spoon and level your flour instead of scooping directly from the bag. This prevents overpacking, which can lead to a dense cake.
- Don’t skip the parchment paper: Lining your pan with parchment helps the cake release easily, ensuring a beautiful presentation once inverted.
- Check for doneness carefully: Ovens vary in temperature; start checking for doneness at 50 minutes. A toothpick should come out clean or with just a few moist crumbs attached.
- Let it cool completely: Allowing the cake to cool fully before inverting helps maintain its structure and prevents breakage.
