Grapefruit Greek Yogurt Cake with Fresh Citrus Zest

A moist, tender cake brightened with fresh grapefruit zest and juice, balanced by tangy Greek yogurt for extra richness. The citrus adds vibrant flavor without overwhelming sweetness, making this perfect for brunch gatherings, spring celebrations, or as a lighter dessert. Greek yogurt keeps the crumb incredibly soft while adding protein, setting this version apart from traditional butter-based cakes.

FAQ

Can I use regular yogurt instead of Greek yogurt?

Regular yogurt will work but drain it first or the cake may be too wet. Greek yogurt provides better structure and tanginess.

What if I don't have fresh grapefruit juice?

Bottled 100% grapefruit juice works fine, though fresh gives brighter flavor. Avoid juice cocktails with added sugar.

How long does this cake keep?

Stays moist for 2 days at room temperature covered, or up to 5 days refrigerated. Freezes well for 3 months wrapped tightly.
