Ingredients for Pound Cake Recipe Using Sour Cream

Nine simple pantry staples create this ultra-moist, buttery pound cake with a golden crust.

The butter and sour cream are non-negotiable for that signature texture. Use high-fat, full-fat sour cream—low-fat versions won’t deliver the same richness. Plugrá or Kerrygold butter are excellent choices for a pronounced buttery flavor. Ensure all dairy ingredients are at room temperature to prevent curdling. For the flour, King Arthur or Gold Medal all-purpose work beautifully.

No sour cream? Full-fat Greek yogurt at a 1:1 ratio works in a pinch. Out of buttermilk? Replace the milk with buttermilk for a tangier crumb. For a citrus variation, orange zest instead of lemon adds a lovely brightness. The vanilla extract can be swapped for almond extract at half the amount for a different flavor profile.

Store the cake in an airtight container at room temperature for up to 5 days. For longer storage, wrap slices tightly in plastic and freeze for up to 3 months. The cake actually improves overnight as the flavors meld together.

Step-by-Step Instructions for Pound Cake Using Sour Cream

Follow this precise method to achieve that signature ultra-moist crumb with buttery richness every time.

Step 1: Cream Butter and Sugar to Ideal Consistency

In a stand mixer fitted with the paddle attachment, beat the 1 cup Unsalted Butter on medium-high speed for 1 minute until smooth and creamy. The butter should be at room temperature to properly incorporate air.

Gradually add the 2 cups Granulated Sugar and continue beating for 5-7 minutes until the mixture is pale yellow and noticeably increased in volume. This creaming process is critical—it aerates the base for a tender crumb. Stop to scrape down the bowl sides halfway through.

Step 2: Incorporate Eggs and Flavoring Agents

Add the 6 whole Large Eggs one at a time, mixing on medium speed for 30 seconds after each addition. Ensure each egg is fully incorporated before adding the next. Room temperature eggs emulsify better into the butter mixture.

Once all eggs are added, mix in the 2 tsp Pure Vanilla Extract and 1 tbsp Lemon Zest. The mixture should appear smooth and slightly glossy at this stage. The lemon zest adds a subtle brightness that balances the richness.

Step 3: Alternate Dry and Wet Ingredients

In a separate bowl, whisk together the 3 cups All-Purpose Flour, 1 tsp Baking Powder, and 0.5 tsp Salt. With the mixer on low speed, add one-third of the flour mixture to the butter mixture and mix just until combined.

Pour in half of the 1 cup Full-Fat Sour Cream and mix until incorporated. Repeat, alternating with the remaining flour mixture and sour cream, ending with the final third of flour. The sour cream ensures the ultra-moist crumb promised in the title.

Step 4: Add Milk and Finalize the Batter

Gradually pour in the 0.25 cup Whole Milk while mixing on low speed until the batter is smooth and homogeneous. The batter should be thick but pourable—like a thick pancake batter. Avoid overmixing, which can develop gluten and result in a dense cake.

Use a silicone spatula to give the batter one final fold by hand, ensuring all ingredients at the bottom of the bowl are fully incorporated. The batter should have a velvety texture with no visible flour streaks.

Step 5: Bake to Golden Perfection

Pour the batter into a greased and floured 10-inch bundt pan or 9×5-inch loaf pan. Smooth the top with the spatula. Tap the pan gently on the counter 2-3 times to remove any large air bubbles.

Bake in a preheated 325°F oven for 75-90 minutes or until a toothpick inserted into the center comes out with only a few moist crumbs attached. The top should be deep golden brown and the edges should begin to pull away from the pan sides.

Allow the cake to cool in the pan for 15 minutes, then turn it out onto a wire rack to cool completely. This resting period prevents the cake from crumbling while maintaining its ultra-moist texture.

Common Mistakes When Making This Dish

Overmixing the Batter

Once you add the flour, mix just until it disappears. Overmixing develops gluten, which turns your cake dense instead of tender. I use the mixer on low speed and stop as soon as the batter looks uniform. 💡

Cold Ingredients

All dairy must be at room temperature to emulsify properly. Cold butter won’t cream correctly, and cold eggs can cause the batter to curdle. I take mine out 2 hours before starting.

Skipping the Creaming Step

Beating butter and sugar for 5-7 minutes incorporates air, which creates that light texture. Don’t rush this—pale yellow and fluffy is what you want. This is the foundation of your cake’s texture.

Incorrect Pan Prep

A well-greased and floured pan prevents sticking. I use baking spray with flour or butter plus a dusting of flour. For bundt pans, don’t miss the crevices where batter can stick.

Overbaking the Cake

Pull it out when a toothpick has just a few moist crumbs. Overbaking dries out the cake, defeating the purpose of using sour cream. My oven runs hot, so I start checking at 70 minutes. 🔥

Ignoring the Rest

Let the cake cool in the pan for 15 minutes before turning out. This allows it to set slightly so it doesn’t break apart. Then cool completely on a rack to maintain that ultra-moist crumb.
