Ingredients for amazing pound cake

Buttermilk magic plus these 11 simple staples create a pound cake that stays moist for days.

The butter matters—unsalted, room temperature is non-negotiable. Land O'Lakes or Plugrá are my go-tos, but any good brand works. Sift the flour to avoid dense cake—King Arthur or Gold Medal are reliable. For buttermilk, if you don't have it, mix 1.5 tbsp lemon juice or vinegar with 1.5 cups milk and let sit 5 minutes. The lemon zest? Use a microplane for fine texture—no zest bag graters here. Eggs should be room temp too, so take them out 30 minutes before baking.

No buttermilk? Milk plus acid (lemon juice or vinegar) works perfectly. Short on vanilla? Almond extract at half the amount adds depth. The baking powder is key—Diamond Crystal is double-acting, so use it as written. For a richer flavor, swap 1/4 cup of the all-purpose flour for cake flour. The powdered sugar is optional but adds that classic pound cake finish—skip it if you're serving it plain with fruit.

This cake keeps for 5-6 days at room temp in an airtight container, or 1 week in the fridge. For longer storage, freeze slices wrapped in plastic for up to 3 months. The buttermilk keeps it so moist that it actually tastes better the second day—perfect for making ahead. Dust with powdered sugar right after baking while still warm for that classic look.

Step-by-step instructions for buttermilk-infused pound cake

Here's how to create a pound cake with legendary moisture and texture that stays perfect for days.

In a stand mixer fitted with the paddle attachment, beat the 1 cup unsalted butter and 2 cups granulated sugar on medium speed for 3-4 minutes until the mixture is pale and nearly doubles in volume. You'll see ribbons form when you lift the paddle—this means you've incorporated plenty of air for that signature tender crumb.

I like to scrape down the sides of the bowl every minute or so to ensure everything gets evenly creamed. If you're using a hand mixer, this will take about 5 minutes of steady mixing. The butter should be completely smooth with no graininess, and the mixture should look almost fluffy. This step is what gives pound cake its signature richness and moisture.

Add the 4 whole large eggs, one at a time, mixing on low speed for 30 seconds after each addition until fully incorporated. Then add the 2 tsp pure vanilla extract and 1 tbsp lemon zest, mixing just until combined. The lemon zest will add a bright citrus note that complements the buttery richness perfectly.

Here's the thing—don't overmix here. You want the eggs to blend smoothly but not create too many air bubbles. The batter should be thick and smooth, like a pale yellow ribbon. If you see any streaks of egg white, give it just a few more seconds to fully incorporate. The lemon zest is crucial—it's what gives this cake its signature brightness that keeps it from being too heavy.

In a separate bowl, whisk together the 2.5 cups all-purpose flour, 2 tsp baking powder, and 0.5 tsp salt. With the mixer on low speed, add about ⅓ of the flour mixture to the butter mixture and mix just until combined. Then add ½ of the 1.5 cups buttermilk and mix until smooth.

Repeat this process, alternating between the remaining flour mixture and the remaining buttermilk, ending with the buttermilk. The key here is to mix just until combined—you should still see some flour streaks. Overmixing develops gluten and makes the cake tough. The buttermilk is what gives this cake its legendary moisture and tender crumb. Don't skip this alternating method—it creates the perfect texture.

Gently fold in the 2 tbsp lemon juice using a spatula. The lemon juice adds another layer of brightness that balances the richness of the butter. Preheat your oven to 350°F and grease a 9x5-inch loaf pan thoroughly with butter, then dust with flour, tapping out any excess. This ensures the cake won't stick and comes out cleanly.

Pour the batter into the prepared pan and smooth the top with a spatula. The batter should fill the pan about ¾ full. Gently tap the pan on the counter a few times to release any air bubbles. The cake will rise beautifully, so don't overfill it. Place the pan in the center of the oven and bake for 50-60 minutes, or until a toothpick inserted in the center comes out clean.

Remove the cake from the oven and let it cool in the pan for 10 minutes. Then invert it onto a wire rack to cool completely. This gradual cooling process helps the cake set properly and develop its full flavor. I know it's tempting to cut into it right away, but patience here is key—waiting ensures the cake holds its shape when you slice it.

Once completely cool, dust the top with the 0.5 cup powdered sugar if desired. This pound cake is amazing served at room temperature, but it also reheats beautifully. Store leftovers wrapped tightly at room temperature for up to 5 days or refrigerate for up to 1 week. The buttermilk infusion keeps it incredibly moist even after several days.

Pro cooking tips for this recipe

Butter Temperature Matters

The butter must be room temperature—no exceptions. Cold butter creates dense pockets in your cake, while overly soft butter can cause the batter to separate. I test by pressing a thumb into the butter: it should leave a slight indentation but hold its shape. For best results, take the butter out of the fridge 1 hour before baking or use the microwave on 30-second intervals until just softened. Land O'Lakes or Plugrá brands work perfectly for this recipe. 🧈

Pro Mixing Technique

When creaming butter and sugar, mix until the mixture is pale and fluffy with ribbons forming when you lift the paddle. This takes 3-4 minutes with a stand mixer or 5 minutes with a hand mixer. Scrape the bowl every 60 seconds to ensure even mixing. Overmixing here can incorporate too much air, leading to a cake that collapses during baking. The goal is to create a light, airy base for that signature tender crumb. 💛

Buttermilk Substitute

If you don’t have buttermilk, make your own by mixing 1.5 tbsp lemon juice or white vinegar with 1.5 cups milk. Let it sit for 5 minutes until slightly thickened. Never use cold buttermilk—it can cause the cake to sink. For extra richness, I sometimes replace ¼ cup of the all-purpose flour with cake flour, which adds a finer texture. The buttermilk is what keeps this cake moist for days! 🥛

Pan Prep for Perfect Release

Grease your 9x5-inch loaf pan thoroughly with butter, then dust with flour, tapping out any excess. This ensures the cake releases cleanly without sticking. For extra insurance, I line the pan with parchment paper cut to fit snugly. If you skip this step, the cake may tear when inverting. Bake at 350°F for 50-60 minutes—a toothpick inserted in the center should come out clean. 🍳

Lemon Zest vs. Juice

The lemon zest adds brightness and prevents the cake from tasting too heavy, while the lemon juice balances the richness. Use a microplane for fine zest—no zest bag graters! For maximum flavor, zest 1 lemon and juice 2 tbsp. If you prefer a milder taste, reduce the zest to ½ tbsp but keep the juice. The citrus keeps this cake feeling light and refreshing. 🍋

Cooling for Best Texture

Let the cake cool in the pan for 10 minutes before inverting onto a wire rack. This gradual cooling prevents cracking and helps the cake set properly. If you cut into it too soon, the crumb will be gummy. For the best results, wait at least 1 hour before slicing. The buttermilk keeps it moist even after cooling, making it perfect for meal prep. ✨
