Sour Cream Pound Cake Recipe With Cake Flour: Ultra Moist Crumb and Buttery Richness

This pound cake delivers the ultra-moist crumb that made the classic famous. The secret lies in combining rich sour cream with fine cake flour for a texture that’s impossibly tender yet sturdy enough to hold its shape.

Every slice reveals a golden crust with a velvety interior, proving that simple ingredients can create extraordinary results. The buttery richness comes through in every bite without being heavy.

Ingredients for Sour Cream Pound Cake Recipe with Cake Flour

Nine simple ingredients create that signature ultra-moist crumb with buttery richness in every slice.

The butter is critical here—use a high-fat European style like Plugrá or Kerrygold for that rich, velvety texture. Cake flour is non-negotiable (the fine mill gives the tender crumb), and Swans or Softasilk are reliable brands. Sour cream should be full-fat; Breakstone’s or Daisy work perfectly. Always check your baking powder’s expiration date—old leavening = flat cake. Room temperature ingredients blend evenly, so set them out 1 hour before mixing.

No cake flour? Measure 3 cups all-purpose, remove 6 tbsp, replace with 6 tbsp cornstarch, then sift. Sour cream can be swapped for full-fat Greek yogurt (same tang, slightly denser crumb). For extra richness, brown the butter first (let it cool to room temp before creaming). The lemon zest is optional but brightens the flavor—use a Microplane for fine, even strands. Vanilla paste works too, with those pretty speckles.

The cake keeps beautifully at room temperature, wrapped in foil, for 4-5 days. For longer storage, slice and freeze—thaw overnight on the counter. Baked cakes can also be frozen whole for up to 3 months. Serve at room temperature for the best texture (cold muffles the flavors).

Step-by-Step Instructions for Sour Cream Pound Cake With Cake Flour

This method ensures a perfectly moist, tender crumb with rich butter flavor in every slice.

Step 1: Cream Butter and Sugar to Light and Fluffy

In a large mixing bowl, beat the 1.5 cup Unsalted Butter and 2.5 cups Granulated Sugar together on medium speed for 4-5 minutes. The mixture should become pale yellow and noticeably lighter in texture.

This creaming process incorporates air, which creates a fine, even crumb in your finished cake. Stop occasionally to scrape down the sides of the bowl with a spatula to ensure even mixing. You’ll know it’s ready when the mixture clings to the sides of the bowl briefly before falling.

Step 2: Incorporate Eggs and Flavorings

Add the 6 whole Large Eggs one at a time, beating well after each addition for 20-30 seconds. This gradual incorporation prevents curdling and ensures a smooth batter. After the eggs, mix in the 2 tsp Vanilla Extract and 1 tbsp Lemon Zest.

The batter will look slightly thick and glossy at this stage. If using the optional lemon zest, make sure it’s finely grated to distribute its bright citrus flavor evenly without altering the cake’s texture.

Step 3: Alternate Dry and Wet Ingredients

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

Pour in half of the 1 cup Full-Fat Sour Cream, then beat until smooth. Repeat, adding another third of the flour, the remaining sour cream, and finally the last of the flour. Mix just until the batter is uniform—overmixing will develop gluten and make the cake dense.

Step 4: Bake Until Golden and Set

Pour the batter into a greased and floured 10-12 cup Bundt pan or 9×5-inch loaf pan. Smooth the top with a spatula and tap the pan gently on the counter once or twice to remove any air bubbles.

Bake in a preheated 325°F oven for 60-75 minutes (Bundt) or 70-80 minutes (loaf) until the top is golden brown and a toothpick inserted in the center comes out clean or with a few moist crumbs. Check at 60 minutes—ovens vary.

Step 5: Cool Completely Before Slicing

Let the cake cool in the pan on a wire rack for 15 minutes. Then, carefully invert it onto the rack to cool completely. This resting period prevents the cake from breaking apart while still warm.

Allow it to cool for at least 2 hours before slicing. This patience ensures the crumb sets properly, giving you clean, even slices with that promised ultra-moist texture. Serve at room temperature for the best flavor.

Serving Suggestions for Leftovers

Classic Presentation

Dust the cooled cake with powdered sugar for a simple, elegant finish that highlights its golden crust. I use a fine-mesh sieve for even coverage. A light dusting of 1-2 tbsp is plenty for a 10-inch Bundt. 💫

Fruit Pairings

Serve slices with macerated berries—toss 2 cups mixed berries with 1 tbsp sugar and let sit for 15 minutes. The natural juices create a light sauce. Fresh peaches or pears work beautifully too, especially in summer.

Whipped Cream

Offer a dollop of sweetened whipped cream on the side. I whip 1 cup heavy cream with 2 tbsp powdered sugar and 1 tsp vanilla until soft peaks form. It adds a cloud-like contrast to the dense, moist crumb.

Ice Cream Option

Warm individual slices in the microwave for 10-15 seconds and top with vanilla bean ice cream. The temperature contrast is divine. I love Blue Bell or Jeni’s for this—both hold up well to the cake’s richness.

Beverage Match

A cup of hot coffee or Earl Grey tea cuts through the buttery richness. For a special treat, serve with sweet dessert wine like Moscato d’Asti—its light bubbles and stone fruit notes complement the cake perfectly. 🍷
