What Kind of Butter Should I Use?
For this grapefruit pound cake, it’s best to use unsalted butter that is softened to room temperature. Unsalted butter allows you to control the salt content in your recipe more precisely, which is especially important in a sweet dessert like this one where the citrus flavor needs to shine. Additionally, using softened butter ensures that it can cream effectively with the sugar, creating a light and airy texture that contributes to the cake’s moistness. If you only have salted butter on hand, you can still use it; just be sure to reduce or omit the added salt in the recipe to maintain balance in flavor.
Ingredients You’ll Need
Each ingredient in this dish plays an essential role in flavor and texture. Here’s what you’ll need:
- 1 cup unsalted butter (softened): Provides richness and moisture for a tender crumb.
- 2 cups granulated sugar: Enhances sweetness and contributes to the cake’s structure.
- 4 large eggs: Binds the ingredients together and adds moisture for a fluffy texture.
- 3 cups all-purpose flour (sifted): Forms the base of the cake, giving it stability and texture.
- 1 cup grapefruit juice (freshly squeezed): Infuses the cake with a bright, citrusy flavor.
- 2 tablespoons grapefruit zest: Adds an aromatic burst of grapefruit essence for depth.
- 1 tablespoon baking powder: Helps the cake rise, ensuring a light and airy finish.
- 1 teaspoon salt: Balances sweetness and enhances the overall flavors.
How To Make the Grapefruit Pound Cake

Preheat and Prepare the Pan
Preheat your oven to 350°F (175°C) and prepare your loaf pan by greasing it thoroughly with butter and dusting it with flour. This ensures that your pound cake will release easily after baking, giving it a beautiful shape.
Cream the Butter and Sugar
In a mixing bowl, combine the softened unsalted butter and granulated sugar. Use an electric mixer on medium speed to cream them together until the mixture is light, fluffy, and pale in color, which should take about 3-5 minutes. This step incorporates air into the batter, helping the cake rise beautifully.
Incorporate the Eggs
Add the four large eggs to the creamed mixture one at a time. Mix well after each addition until fully incorporated. The eggs will help bind the ingredients together and contribute to the cake’s moist texture.
Combine Dry Ingredients
In a separate bowl, sift together the all-purpose flour, baking powder, and salt. This process not only combines these dry ingredients but also aerates them, making it easier to mix with the wet ingredients later.
Mix Batter with Juice
Gradually add the dry ingredient mixture to the butter mixture while alternating with the freshly squeezed grapefruit juice. Start with a third of the dry mixture, then add half of the juice, continuing this pattern until everything is just combined. Be careful not to overmix; you want a smooth batter without lumps for best texture.
Fold in Grapefruit Zest
Gently fold in two tablespoons of grapefruit zest into your batter using a spatula. This will enhance the citrus flavor without losing any air from your batter. You’ll know it’s ready when you see even distribution of zest throughout.
Pour Batter into Pan
Pour your batter into the prepared loaf pan and use a spatula to smooth out the top evenly. Ensure there are no air pockets trapped in the batter, as this could affect how evenly it bakes.
Bake Until Golden
Place your loaf pan in the preheated oven and bake for 60 minutes. The cake is done when it’s deeply golden on top and a toothpick inserted into the center comes out clean or with just a few moist crumbs attached.
Cool Before Serving
Once baked, remove your pound cake from the oven and let it cool in the pan for 10 minutes. Afterward, transfer it carefully to a wire rack to cool completely before glazing; this helps maintain its structure and prevents sogginess.
Whisk Together Glaze
In a small bowl, whisk together one cup of powdered sugar with two tablespoons of grapefruit juice until you achieve a smooth consistency. The glaze should be slightly thickened but pourable; adjust by adding more juice or sugar if necessary for your desired thickness.
Drizzle Over Cake
Once your pound cake has cooled completely, drizzle the prepared glaze over the top. Allow some of it to drip down the sides for an enticing presentation while ensuring an even coating for that delightful sweet-tart flavor contrast.
How to Serve and Store Grapefruit Pound Cake
This delightful Grapefruit Pound Cake makes 8 servings, perfect for sharing with friends and family. For a beautiful presentation, slice the cake and serve it on a decorative platter, drizzled with the refreshing grapefruit glaze. Pair it with a dollop of whipped cream or a scoop of vanilla ice cream to enhance its moist texture, while fresh mint leaves can add a pop of color and flavor.
To store any leftovers, wrap the cake tightly in plastic wrap or place it in an airtight container to keep it fresh for up to five days in the refrigerator. When you’re ready to enjoy another slice, simply reheat it in the microwave for about 10-15 seconds; this will help restore its softness without drying it out. Keep in mind that while this cake can be frozen for up to three months, the texture may change slightly upon thawing, so it’s best enjoyed fresh!
