How to Make Grapefruit Pound Cake
Step 1: Preheat Your Oven
First things first—preheat your oven to 350˚F (175˚C) and grease two 8-inch loaf pans. This step ensures that your cakes bake evenly and don’t stick to the pans.
Step 2: Cream Butter and Sugar
In your stand mixer fitted with the paddle attachment, beat together the butter and sugar until fluffy—this should take about five minutes. Remember to scrape down the sides halfway through. This process incorporates air into the mixture, giving your pound cake that lovely light texture.
Step 3: Prepare Your Grapefruits
Wash and zest those grapefruits before juicing them. Zesting releases oils that add incredible flavor to your cake. Just make sure not to mix with aluminum tools; we want all that tangy goodness without any weird aftertaste!
Step 4: Add Eggs One at a Time
With your sugar mixture nice and fluffy, add in the eggs one at a time. Make sure to beat well after each addition; this helps create an even batter.
Step 5: Switch Gears If Needed
If you’re using an aluminum paddle on your mixer, switch it up now! Take off the bowl and continue mixing by hand with a wooden spoon or use stainless steel options if available—this avoids any unwanted reactions between aluminum and grapefruit.
Step 6: Stir in Zest
Once you’ve added all your eggs, gently stir in the grapefruit zest with that trusty wooden spoon we talked about earlier. It helps distribute that bright flavor throughout your batter.
Step 7: Combine Dry Ingredients
In a separate bowl, whisk together flour, baking soda, and baking powder. Mixing these dry ingredients first ensures they’re evenly distributed in your batter.
Step 8: Mix Buttermilk and Juice
In another small bowl, combine buttermilk with a quarter cup of freshly squeezed grapefruit juice. The acidity from the juice helps keep the cake moist while adding flavor.
Step 9: Alternate Dry and Wet Ingredients
Now comes the fun part! Gradually add in one-fourth of your flour mixture followed by one-third of your buttermilk mixture into the mixing bowl. Repeat until everything is well combined—start and end with flour.
Step 10: Divide Batter into Pans
Pour equal amounts of batter into each loaf pan, smoothing out the tops as needed.
Step 11: Bake Until Golden
Bake in preheated oven for about 40-50 minutes or until a toothpick inserted comes out clean. The smell will be heavenly!
Step 12: Cool Down
Once baked, let those loaves cool on a wire rack before moving on to glaze them.
Step 13: Prepare Glaze
While cooling, mix powdered sugar with two to three tablespoons of leftover grapefruit juice until you achieve a drizzling consistency—thin enough to pour but thick enough to cling nicely!
Step 14: Drizzle Away!
Pour that gorgeous glaze over each cooled loaf and let it set up beautifully before slicing.
Step 15: Slice & Serve
Finally, slice up that delightful Grapefruit Pound Cake! Serve it up at gatherings or enjoy it all week long—you deserve every sweet morsel!
Enjoy making memories over this lovely dessert!
Pro Tips for Making Grapefruit Pound Cake
Making grapefruit pound cake is a delightful experience, and with these tips, you can ensure it turns out perfectly every time!
-
Use room temperature ingredients: Having your butter and eggs at room temperature helps them mix more easily and creates a fluffier batter. This results in a lighter cake texture that melts in your mouth.
-
Don’t rush the mixing process: Beating the butter and sugar until fluffy may feel tedious, but this step is crucial for incorporating air into the batter. The more air you incorporate, the lighter your cake will be!
-
Avoid aluminum tools: Grapefruit juice reacts with aluminum, which can affect the taste of your cake. Using stainless steel or glass tools ensures you get that pure grapefruit flavor without any metallic undertones.
-
Check doneness carefully: Every oven is unique, so start checking your cake around the 40-minute mark. Insert a toothpick into the center; if it comes out clean, your cake is ready to come out of the oven.
-
Let it cool completely: Cooling on a wire rack allows steam to escape, preventing sogginess. A properly cooled pound cake will hold its shape better when sliced and glazed.
