Ruby Red Grapefruit Sheet Cake with Grapefruit Cream Cheese Frosting is tender, moist, sweet, and tart. If you like citrus and grapefruit, this flavorful combination is sure to satisfy!

The perfect breakfast…er, because grapefruit is great for breakfast, am I right?

That’s my story and I’m sticking to it!

This cake is wonderfully dense and moist. The batter is very wet resulting in an almost brownie like cake.

It has a delightful citrus flavor that is clearly grapefruit. There’s no mistaking it for orange, lemon, or lime. It has a unique, mild grapefruit flavor. It’s actually a refreshing cake flavor that you grow to like more and more with every bite!

I smothered this cake in a smooth cream cheese frosting that has a kiss of grapefruit flavor. I used a basic Cream Cheese Frosting and added one tablespoon grapefruit zest to it. However, if you think this is too much grapefruit, you may choose to frost simply with the cream cheese frosting. You really can’t beat the classic!

Fresh grapefruit is available to me all year, so I consider this a year-round dessert. It makes a memorable and pretty cake for birthday celebrations as well as potlucks or entertaining.

Ruby Red Grapefruit Sheet Cake with Grapefruit Cream Cheese Frosting

1. I recommend using real butter and not margarine.
2. You can substitute sour cream or Greek yogurt for the buttermilk. You’ll use 1/2 cup for substitutions.
3. Additionally, you can use a plain cream cheese frosting, like my Best Cream Cheese Frosting, if you’re concerned with grapefruit overload.
4. You may also consider adding 1 cup chopped pecans, walnuts, or almonds to the cake batter.
