I needed to use up some of the grapefruit in my fruit bowl before it went bad so I decided to try it in a cake! The pink grapefruit I used tinted the cake and the glaze ever so slightly to create a beautiful pink hue. As I mentioned, the cake is super dense and moist so don’t expect it to rise too much, but do expect it to be delicious!

Ingredients Needed to Make Grapefruit Pound Cake

You only need one large grapefruit to make this pound cake. I used a pink grapefruit, but you could also use a ruby red or yellow grapefruit.

• all-purpose flour
• baking soda
• baking powder
• unsalted butter, room temp
• sugar
• eggs, room temp
• fresh-squeezed grapefruit juice
• grapefruit zest
• milk, room temp
• confectioners powdered sugar

How to Make This Super-Moist Pound Cake

1. Preheat the oven to 350°F and prepare a loaf pan with butter or non-stick spray.
2. Mix together the flour, baking soda, and baking powder and set it aside. Zest the grapefruit and then juice it. Strain the pulp set the juice aside as well.
3. Place the butter and sugar in the bowl of a stand mixer (or a large mixing bowl if using a hand mixer) and beat together until creamy. Add the eggs, grapefruit juice, and zest and combine everything.
4. Add half of the dry mixture and half of the milk to the batter and mix in with a silicone spatula or spoon. Once combined, add the rest of the dry ingredients and the milk and fully incorporate everything.
5. Pour the batter into the prepared loaf pan, tap lightly on the counter to remove any air bubbles, and bake for 42-45 minutes or when a toothpick comes out clean. Remove the pan from the oven and allow the loaf to cool in the pan for 10 minutes and then on a cooling rack.

How to Make a Super Easy Grapefruit Glaze

Combine the powdered sugar and grapefruit juice in a medium bowl and whisk together until smooth. Immediately pour over the top of the cooled loaf and allow the glaze to set. Sprinkle with more fresh zest if desired and enjoy!

Ingredients

Grapefruit Pound Cake

• 1½ cups all-purpose flour
• ¼ tsp baking soda
• ¼ tsp baking powder
• ½ cup unsalted butter, room temp
• 1 cup sugar

• ½ cup fresh-squeezed grapefruit juice

Grapefruit Glaze

• 1 cup confectioners powdered sugar

Instructions

• Preheat the oven to 350°F and prepare a loaf pan with butter or non-stick spray. TIP: I used the wrapper from my butter and it worked perfectly!
  
• In a medium mixing bowl, mix together the flour, baking soda, and baking powder and set it aside. Zest the grapefruit and then juice it. Strain the pulp from the liquid, discard the pulp, and set the juice and zest aside as well.
  
• Place the butter and sugar in the bowl of a stand mixer (or a large mixing bowl if using a hand mixer) and beat together until creamy, about 5-6 minutes. Add the eggs, grapefruit juice, and zest and continue beating until everything is combined. Remove the bowl from the stand mixer.

• Pour the batter into the prepared loaf pan, tap lightly on the counter to remove any air bubbles, and bake for 42-45 minutes or when a toothpick comes out clean. Remove the pan from the oven and allow the loaf to cool in the pan for 10 minutes and then on a cooling rack.
  
• Once the loaf has cooled, combine the powdered sugar and grapefruit juice in a medium bowl and whisk together until smooth. Immediately pour over the top of the cooled loaf and allow the glaze to set. Sprinkle with more fresh zest if desired and enjoy!
  

Notes

• I’ve read that grapefruit juice and aluminum have a bad reaction together and create a bad taste in the bread so avoid aluminum tools when mixing the batter.
