- 1 and 1/2 teaspoons baking powder
- 1/2 teaspoon salt
- 3 large eggs
- 3/4 cup (180g) Greek yogurt (I use plain!)
- 1 cup (200g) packed light brown sugar
- 1/2 cup (120ml) vegetable or canola oil
- 1/4 cup (60ml) freshly squeezed grapefruit juice
- 1 and 1/2 Tablespoons grapefruit zest (from about 1 large grapefruit)
- 1 teaspoon pure vanilla extract
- seeds scraped from 1/2 of a vanilla bean (optional, but SO good!)

- 2 Tablespoons (30ml) freshly squeezed grapefruit juice (for the glaze!)

How to Prepare Grapefruit Greek Yogurt Loaf Cake
Okay, ready to get baking? Don’t worry, it’s easier than you think! Just follow these simple steps, and you’ll have a delicious Grapefruit Greek Yogurt Loaf Cake in no time.
Preparing the Batter
First things first, let’s get that batter ready!
- Grab a big bowl and whisk together the flour, baking powder, and salt. Set it aside for now.
- In a separate bowl (medium-sized is perfect), whisk those eggs until they’re nicely combined.
- Now, whisk in the Greek yogurt, brown sugar, oil, grapefruit juice, grapefruit zest, vanilla extract, and vanilla bean seeds (if you’re using them – trust me, they add a *lot*!).
- Pour the wet stuff into the dry stuff and gently mix it all together with a wooden spoon or rubber spatula. Don’t overmix! A few streaks of flour are totally fine. Seriously, that’s key!
Baking the Grapefruit Greek Yogurt Loaf Cake
Time to bake!
- Preheat your oven to 350°F (177°C). And grease a 9×5-inch loaf pan REALLY well. I hate it when cake sticks!
- Pour the batter into that pan and spread it out evenly.
- Bake for 45-50 minutes. You’ll know it’s ready when a toothpick inserted into the center comes out clean. If you see the top browning too fast, just loosely cover it with aluminum foil. Problem solved!
Glazing and Serving Your Grapefruit Greek Yogurt Loaf Cake
Almost there! Now for the finishing touch…
- Take the cake out of the oven and let it cool on a wire rack. Let it cool *completely* before glazing. Trust me on this one!
- While it’s cooling, whisk together the confectioners’ sugar, grapefruit juice, and vanilla extract for the glaze.
- Once the cake is cool, drizzle that glaze all over the top. It’s so pretty!
- Slice it up and serve! It’s great on its own, but even better with a cup of coffee or tea. Enjoy! Leftovers will keep at room temp for up to 5 days. Though, honestly, it never lasts that long at my place!

Tips for the Best Grapefruit Greek Yogurt Loaf Cake
Want to make sure your Grapefruit Greek Yogurt Loaf Cake is *perfect* every time? Here are a few little secrets I’ve learned along the way!
Don’t Overmix the Batter
Seriously, this is a big one! Overmixing develops the gluten in the flour, and that means a tough, dense cake. Yuck! Just mix until everything’s *just* combined, and you’ll be golden.
Use Fresh Grapefruit Juice and Zest
Okay, this might seem obvious, but it makes *such* a difference. Bottled juice just doesn’t have the same zing, and the zest is where all the grapefruit’s amazing oils are hiding. Fresh is best, always!
Let the Cake Cool Completely Before Glazing
Patience, grasshopper! If you glaze the cake while it’s still warm, the glaze will just melt right off and make a sticky mess. Nobody wants that! Let it cool completely, and you’ll get a nice, pretty glaze that sets up perfectly.
Variations for Your Grapefruit Greek Yogurt Loaf Cake
Okay, so you’ve mastered the basic recipe? Awesome! Now let’s get a little crazy and try some fun variations on this Grapefruit Greek Yogurt Loaf Cake. Don’t be afraid to experiment!
Add Different Citrus Zest
Grapefruit’s great, but why not mix things up? Try using lemon or orange zest instead! Each one brings its own unique flavor to the party. Lemon is super bright, and orange is a little sweeter. Yum!
Incorporate Poppy Seeds
Poppy seeds add a nice little crunch and a subtle nutty flavor. Just toss in a tablespoon or two to the batter before baking. Trust me, it’s a yummy addition to this Grapefruit Greek Yogurt Loaf Cake!
Top with a Streusel Topping
Want to add some extra sweetness and texture? Make a simple streusel topping! Just mix together some flour, sugar, butter, and maybe a pinch of cinnamon. Sprinkle it over the top of the cake before baking. So good!
Serving Suggestions for Grapefruit Greek Yogurt Loaf Cake
Okay, so you’ve got this amazing Grapefruit Greek Yogurt Loaf Cake…now what? Here are a few ideas to take it to the next level!
Pair with Coffee or Tea
Seriously, a slice of this cake with a hot cup of coffee or tea? It’s a match made in heaven! The warm drink just brings out all the grapefruit-y goodness. It’s my go-to breakfast!
Serve with Fresh Fruit
Want to make it a little healthier? (Okay, maybe not *healthier*, but you know…). Serve it with some fresh grapefruit segments or a handful of berries. So pretty and delicious!
Add a Dollop of Greek Yogurt
If you’re feeling extra fancy (or just want more yogurt, like me!), top a slice with a dollop of plain Greek yogurt. It adds a nice tang that complements the sweetness of the cake. Trust me, it’s *good*.
Storing & Reheating Your Grapefruit Greek Yogurt Loaf Cake
Okay, so you made this amazing Grapefruit Greek Yogurt Loaf Cake…and somehow you have leftovers? Wow! Here’s how to keep it fresh and delicious.
Storage Instructions
You can totally keep this cake at room temperature for a few days – just wrap it up tight! Or, pop it in the fridge for even longer. It’s yummy cold, too!
Reheating Instructions
Wanna warm it up? Just zap a slice in the microwave for a few seconds. Or, for a really nice treat, warm it in the oven! It’s like it’s fresh out of the pan all over again. Seriously, so good!
Grapefruit Greek Yogurt Loaf Cake FAQs
Got questions about this Grapefruit Greek Yogurt Loaf Cake? I got you! Here are some of the most common questions I get asked, so you can bake with confidence!
Can I use regular yogurt instead of Greek yogurt in this Grapefruit Greek Yogurt Loaf Cake?
Okay, so technically, *yes*, you *can*. But! Greek yogurt is thicker and tangier, which makes the cake extra moist and gives it that yummy flavor. Regular yogurt will work in a pinch, but your cake might be a little less…perfect. Just sayin’!
Can I freeze the Grapefruit Greek Yogurt Loaf Cake?
Absolutely! This cake freezes beautifully. Just wrap it really well in plastic wrap and then foil, and it’ll keep in the freezer for up to 2-3 months. When you’re ready to eat it, let it thaw overnight in the fridge. It’ll be just as good as the day you baked it! (Maybe even better, if you ask me!).
What can I substitute for grapefruit juice in the Grapefruit Greek Yogurt Loaf Cake?
No grapefruit on hand? No worries! You can totally use orange juice or lemon juice instead. Orange will give it a sweeter flavor, and lemon will make it a bit more tart. Both are delicious! Just use the same amount as the recipe calls for.
Is it possible to make this recipe gluten free?
Yep! Just swap out the all-purpose flour for a gluten-free blend. I’ve had good luck with a 1:1 replacement. Keep an eye on the baking time, though, as gluten-free flours can sometimes bake a little differently. You might need to adjust it slightly. But totally doable!
