1 Egg Pound Cake Recipe: Ultra-Moist Crumb Without a Lick of Butter

This 1-egg pound cake recipe delivers restaurant-quality moisture without a single pat of butter—just one egg and clever science. The secret lies in vegetable oil and a precise mix of dry ingredients that create a tender, ultra-light crumb while keeping the structure intact. After years of testing, this version proves you don’t need butter or multiple eggs for a cake that stays moist for days.

What makes this recipe work is the balance between sugar and flour, which creates a fine crumb, and the addition of sour cream that adds richness without heaviness. The cake bakes up golden and domed, with a delicate texture that crumbles gently rather than drying out. Unlike traditional pound cakes that require multiple eggs, this version achieves the same luxurious result with just one.

The result is a cake that’s perfect for celebrations or everyday dessert cravings—moist enough to eat plain, but also ideal for frosting or filling. The flavor is subtly sweet with a clean finish, making it versatile for any occasion. Whether you’re baking for a special event or just want a foolproof dessert, this recipe delivers consistent, professional-quality results every time.

For variations, try adding a teaspoon of vanilla extract for classic flavor, or citrus zest for a bright twist. Serve with fresh berries, whipped cream, or a dusting of powdered sugar. The beauty of this recipe is its adaptability—it’s simple enough for beginners but impressive enough for any gathering. Let’s get baking!

Ingredients for 1 egg pound cake

Eight essential ingredients create a restaurant-quality pound cake with just one egg.

The flour and sugar ratio is critical here—King Arthur all-purpose flour is my go-to for that fine crumb, but any high-quality brand works. Bob's Red Mill is another solid choice if you prefer organic. For sugar, white granulated gives a clean finish, but light brown sugar adds subtle depth. The vegetable oil should be neutral—avoid flavored oils like olive. Room-temperature egg is key for even mixing, so take it out 15 minutes before baking. Sour cream adds richness without heaviness, and full-fat is non-negotiable for that professional texture.

No sour cream? Plain Greek yogurt at half the amount works in a pinch, though it adds tang. Short on butter? Extra oil or neutral-flavored shortening maintains moisture. For vanilla, imitation won't cut it—pure extract is essential. The lemon zest can be swapped for orange zest if you prefer citrus notes. If you're baking at high altitude, reduce the baking powder by one-quarter teaspoon. The powdered sugar is optional but adds that final touch for serving—skip it if you're frosting instead.

Store the cake wrapped tightly in plastic at room temperature for 3 days or in the fridge for up to 1 week. For longer storage, slice and freeze portions for up to 3 months. The cake reheats beautifully—wrap a slice in foil and microwave for 10-15 seconds to restore moisture. I always bake an extra pan—it freezes perfectly for spontaneous dessert cravings. The texture actually improves after 24 hours as the crumb sets.

Step-by-step instructions for ultra-moist 1-Egg pound cake

Master this technique and you'll achieve a tender, moist crumb without relying on butter.

Preheat your oven to 350°F and grease an 8-inch round cake pan generously with vegetable oil, then line the bottom with parchment paper. Sift the 2.5 cups all-purpose flour and 2 teaspoons baking powder together into a medium bowl—this removes lumps and ensures an even rise. In a separate large bowl, whisk the 1.5 cups granulated sugar and 1 cup vegetable oil until fully combined and slightly thickened.

Add the 1 whole large egg, 0.5 cup sour cream, 0.5 cup milk, 1 teaspoon vanilla extract, 0.5 teaspoon salt, and 1 tablespoon lemon zest to the sugar mixture. Whisk until smooth and well incorporated—this creates the foundation for that ultra-moist crumb. The sour cream and oil work together to keep the cake tender, while the lemon zest adds brightness without overpowering.

Gradually add the dry ingredients to the wet mixture, folding in with a rubber spatula until just combined. Avoid overmixing—stop as soon as the flour disappears. The batter should be thick but pourable, resembling pancake batter in consistency. If it looks too thick, add 1-2 tablespoons milk to loosen it slightly. This step is critical for achieving a fine, even crumb without developing gluten.

Melt the 0.25 cup unsalted butter separately in a small saucepan over low heat, then let it cool slightly. Stir the melted butter into the batter until fully incorporated. The butter adds flavor depth and helps create that signature pound cake richness, even though we're using minimal fat overall. The batter should now be smooth and glossy, with no visible streaks of flour.

Pour the batter into the prepared cake pan and smooth the top with a spatula. Bake in the preheated oven for 50-60 minutes, or until a toothpick inserted into the center comes out clean and the cake springs back gently when pressed. The top should be golden brown, but don't overbake—this is where many cakes become dry. If the edges brown too quickly, tent the cake with aluminum foil after 30 minutes to prevent overbrowning.

I've found that baking time can vary slightly depending on your oven, so start checking at the 45-minute mark. The cake is done when it pulls away slightly from the pan edges and develops a crackly top. Remove from the oven and let it cool in the pan for 10 minutes before transferring to a wire rack to cool completely. This resting period allows the moisture to redistribute, ensuring every slice is perfectly tender.

Once completely cooled, dust the top of the cake generously with the 0.25 cup powdered sugar using a fine-mesh sieve. This adds a professional finish and balances the bright lemon flavor. The powdered sugar should melt slightly into the cake's surface, creating a delicate, velvety texture. Slice the cake into 8 equal wedges for serving, ensuring each piece has that signature moist crumb throughout.

For best results, serve the cake at room temperature. The combination of sour cream, vegetable oil, and melted butter creates a tender, moist crumb that stays fresh for up to 3 days when stored properly in an airtight container. The lemon zest adds a subtle citrus brightness that complements the cake's natural sweetness, making this a versatile recipe for any occasion.

Flavor customization for these flavors

Classic Vanilla Twist

Boost the flavor profile by adding 1 teaspoon vanilla bean paste instead of extract for deeper, complex notes. Scrape the seeds from a Madagascar vanilla bean directly into the batter for flecks of flavor. I like to toast the bean briefly over a candle flame before scraping—this enhances its aroma and gives the cake a warm, aromatic depth. 🌿

Citrus Brightness

Swap the lemon zest for orange or grapefruit zest (about 1 tablespoon) for a tropical twist. Pair with 1 teaspoon orange extract for a zesty, refreshing cake. The grapefruit version works beautifully with a white chocolate glaze—melt ½ cup white chocolate chips with 2 tablespoons heavy cream and drizzle over slices. The acidity cuts through the richness perfectly.

Spiced Chai Version

Infuse warmth by adding ½ teaspoon ground cinnamon, ¼ teaspoon ground ginger, and ⅛ teaspoon cloves to the dry ingredients. For extra depth, steep 1 cinnamon stick in the ½ cup milk for 10 minutes before using. This spiced cake pairs wonderfully with chai tea or a scoop of vanilla ice cream. The spices complement the cake’s natural sweetness without overpowering it.

Coffee Mocha

For a decadent twist, dissolve 1 tablespoon instant espresso powder in the ½ cup milk before mixing. Add ½ teaspoon cocoa powder to the dry ingredients for a rich, chocolatey base. Top with a dark chocolate ganache—melt ½ cup dark chocolate chips with ¼ cup heavy cream and drizzle over cooled slices. This version is a crowd-pleaser for coffee lovers.

Almond Joy Fusion

Add ½ cup chopped toasted almonds to the batter for texture, then sprinkle ½ cup shredded coconut on top before baking. After cooling, drizzle with melted white chocolate and extra toasted almonds. The nutty, tropical flavors create a dessert that tastes like a vacation in every bite. 🌴

Salted Caramel

Fold ½ cup caramel sauce into the batter for a gooey center, then sprinkle flaky sea salt (like Maldon) on top before baking. After cooling, drizzle with additional caramel and a pinch of salt. The contrast of sweet, salty, and creamy makes this version irresistible. Serve with a scoop of vanilla bean ice cream for extra indulgence.
