Grapefruit Breakfast Loaf Cake

Grapefruit’s strong, sour citrus flavor can be difficult for some people to warm up to. Growing up, my parents had a grapefruit tree in their yard, and as I kid I remember my mom spooning sugar onto fresh cut grapefruit for my snack, which I thoroughly enjoyed. As an adult, I have graduated from this practice, and now love eating them out of hand, unadorned, or tossed in a salad, or used to brighten up a cocktail. They are truly one of my favorite Sunshine State treats. No matter where you fall on the grapefruit spectrum, I think you’ll agree this cake is a winner. The use of yogurt produces a tender crumb, and balances the acidity from the citrus. A little grapefruit/sugar glaze makes it an indulgent brunch treat.

Grapefruit Zest

Organic is best when using the zest of citrus.


Add half of the flour to the batter.


Alternate adding the yogurt and the flour.

Loaf Pan

Spread the batter evenly in the pan.
