Ingredients for 2 egg butter cake
Buttery richness meets foolproof technique in this ultra-moist cake with velvety frosting.
| Ingredient | Amount | Notes |
|---|---|---|
| Unsalted Butter 🧈 | 1 cup | Cold, cubed for creaming |
| Granulated Sugar 🍚 | 1 ½ cups | White or light brown |
| Large Eggs 🥚 | 2 whole | Room temperature |
| All-Purpose Flour 🌾 | 2 cups | Sifted, plus extra for pan |
| Sour Cream 🥛 | ½ cup | Full-fat for moisture |
| Baking Powder 🍞 | 2 tsp | Aluminum-free preferred |
| Salt 🧂 | ½ tsp | Fine sea salt |
| Vanilla Extract 🌸 | 1 tbsp | Pure, high-quality |
| Milk 🥛 | ¼ cup | Room temperature |
| Powdered Sugar 🍚 | 3 cups | For frosting, sifted |
| Heavy Whipping Cream 🥛 | ½ cup | Cold for frosting |
| Lemon Zest 🍋 | 1 tsp | Fresh, finely grated |
The butter is non-negotiable here—European-style or Land O'Lakes unsalted both work perfectly. Grab it from the deli counter if you want extra-rich flavor, but the standard supermarket tub is fine. Keep it cold until creaming to develop those crucial air pockets. The flour? King Arthur or Gold Medal are my go-tos—they're reliable and consistent. Sift it before measuring to avoid dense layers. As for the sour cream, full-fat is essential for that signature moisture, though Greek yogurt works in a pinch if you're watching calories.
No vanilla extract? Vanilla bean paste gives a similar depth, or vanilla sugar (use half the amount) can save the day. Running low on powdered sugar? Confectioners' sugar from a box is fine, but if you have granulated sugar and a food processor, you can make your own by pulsing it with a pinch of cornstarch. The milk can be whole, 2%, or even almond milk—just make sure it's room temperature for even mixing. For the frosting, heavy whipping cream is ideal, but cool full-fat coconut cream works beautifully for a dairy-free twist. The lemon zest adds brightness—organic lemons from the grocery store work, but if you've got a citrus tree, fresh is always better.
Store the cake in an airtight container at room temperature for up to 3 days, though it's best enjoyed fresh. The frosting keeps for 2 days in the fridge, covered tightly. For longer storage, freeze the unfrosted cake layers for up to 3 months—thaw at room temperature before frosting. The frosting can also be frozen in portions, thawing gently in the fridge. Pro tip: Wrap tightly with plastic wrap pressed directly against the cake to prevent drying. Leftovers? Toasted cake slices make an amazing French toast the next morning.
Why You'll Love This Recipe
- Just Two Eggs: I swear by this—no overcomplicating, no extra eggs to scramble up. Two large eggs, a stick of butter, and a splash of sour cream make this cake ridiculously tender. The butter keeps it moist without tasting greasy, and honestly? It’s the kind of recipe where you’ll second-guess if you need more than that.
- Butter-Soft Magic: That first bite? The sugar caramelizes just enough to give it a subtle crunch, but the butter and sour cream keep it velvety. It’s not sweet like a pound cake—it’s balanced, with a richness that feels indulgent but won’t weigh you down. (Yes, even on a Tuesday night.)
- Leftovers That Last: This cake holds up for days, which is a win for me. Slice it for breakfast toast, pack it in lunches, or reheat a piece in the microwave—it’s still perfect. The sour cream keeps it from drying out, so it’s not one of those sad, crumbly cakes by day three.
- Budget-Friendly Luxury: Four simple ingredients, and you get a cake that tastes like it cost twice as much. Butter and sugar are the stars, but the sour cream adds that extra layer of comfort without breaking the bank. I’ll be real: this is my go-to when I want something special but don’t want to spend hours (or money) on it.
Step-by-step instructions for ultra-moist butter cake
Here's the method that guarantees a tender crumb and rich frosting every time.
Cream Butter and Sugar Until Light and Fluffy
In a stand mixer fitted with the paddle attachment, beat the 1 cup unsalted butter (cold, cubed) and 1.5 cups granulated sugar on medium speed for 3-4 minutes. You're looking for a pale, fluffy mixture that nearly doubles in volume and leaves faint ribbons when the paddle is lifted. This creaming process incorporates air, which creates that signature tender crumb.
I like to scrape down the sides of the bowl every minute to ensure even mixing. The butter should be fully incorporated but still hold its shape when pressed between fingers. If it looks too soft, chill the bowl in the freezer for 5 minutes—this prevents overmixing and ensures proper structure in the final cake.
Add Eggs and Dry Ingredients Alternately
Add the 2 whole large eggs (room temperature) one at a time, mixing on low speed for 30 seconds after each addition. Then stir in the 1 tbsp vanilla extract. In a separate bowl, whisk together the 2 cups all-purpose flour, 2 tsp baking powder, and 0.5 tsp salt. With the mixer on low speed, add ⅓ of the dry ingredients, then the 0.5 cup sour cream, then another ⅓ of the dry ingredients, finishing with the remaining ⅓. Mix just until combined—you should still see small flour streaks.
This alternating method prevents dense layers by evenly distributing moisture. Overmixing develops gluten, which leads to a tough cake. The sour cream adds moisture and richness without making the cake too heavy. Add the 0.25 cup milk and mix until smooth, scraping down the bowl as needed.
Bake in Prepared Pans for Even Rise
Preheat your oven to 350°F. Grease two 9-inch round cake pans with butter and line the bottoms with parchment paper. Divide the batter evenly between the pans and smooth the tops with a spatula. Bake for 25-30 minutes, or until a toothpick inserted into the center comes out clean and the edges pull away slightly from the pan.
I check for doneness at 25 minutes—the cake should spring back when gently pressed in the center. Rotate the pans halfway through baking for even heat distribution. Let the cakes cool in the pans for 10 minutes, then transfer to a wire rack to cool completely. This gradual cooling prevents cracking and ensures level layers for frosting.
Make the Buttery Lemon Frosting
In a medium bowl, beat the 0.5 cup heavy whipping cream (cold) until soft peaks form. Gradually add the 3 cups powdered sugar and 1 tsp lemon zest, beating on high speed until the frosting is smooth and holds stiff peaks. This frosting should be thick enough to pipe but still spreadable—if it's too soft, chill the bowl for 10 minutes before proceeding.
The lemon zest adds a bright contrast to the rich butter cake. For extra flavor, add 1 tsp lemon extract (optional). The frosting should be cool when applied to prevent melting. Spread evenly between the cooled cake layers and over the top and sides for a professional finish.
Pro Tips For Making 2 Egg Butter Cake
- CREAM THE BUTTER SLOWLY: I learned this the hard way—dumping cold butter into sugar and whipping it on high just makes a greasy mess. Instead, soften the butter first (it should dent when pressed), then beat it with the sugar on medium-high for a full 2-3 minutes. You want it to look fluffy and pale, not like wet sand. This isn’t just about texture; it’s how you get that tender crumb in a 2-egg cake.
- USE ROOM-TEMP EVERYTHING: Cold eggs and chilled sour cream are the silent cake killers. Take your eggs out of the fridge 30 minutes before mixing, and let the sour cream sit in warm water for 5 minutes to loosen up. Cold dairy and eggs won’t blend smoothly, and your cake might end up dense or lumpy—especially in a recipe this light.
- DON’T OVERMIX THE BATTER: Once you fold in the dry ingredients, stop as soon as they’re just combined. I used to think more mixing = better rise, but this cake relies on the sour cream’s fat to keep it moist, not gluten development. Overmixing turns it tough, and you’ll end up with a sad, flat loaf instead of that rich, buttery crumb you’re after.
- BAKE UNTIL THE CENTER HITS 205°F: Toothpicks aren’t foolproof—this cake’s dense enough that it might look done but still be gummy inside. Use an instant-read thermometer and pull it out at 205°F (210°F if your oven runs hot). If you’re unsure, tent it with foil 10 minutes before the target time; it’ll finish cooking while you cool it. Trust the temp, not the visual.
Common mistakes when making great 2 egg butter cake
Overmixing the Batter
This is the #1 mistake that turns a tender cake into a dense brick. Once you add the flour, mix just until combined—you should still see small flour streaks. Overmixing develops gluten, which creates a tough, chewy texture. I've ruined many cakes by letting the mixer run too long, so set a timer for 30 seconds after adding the final flour batch and stop immediately. 🌾
Skipping Room-Temperature Ingredients
Cold butter and eggs don't emulsify properly, leading to uneven texture and potential cracks. Take your eggs out of the fridge 30 minutes before baking, and let your butter sit at room temperature for 1-2 hours. I learned this the hard way when my first attempt had greasy pockets in the crumb. The milk should also be room temperature—cold milk can cause the cake to sink in the center.
Incorrect Oven Temperature
Baking at 350°F is crucial—any hotter and the cake will brown too quickly, any cooler and it won't rise properly. I recommend using an oven thermometer to verify your oven's accuracy. If your cake browns too fast, tent it loosely with aluminum foil after 15 minutes. Underbaking is another issue—always check with a toothpick at 25 minutes, not just the timer.
Uneven Batter Distribution
Divide the batter precisely between your two pans—uneven distribution causes one cake to rise higher than the other, making frosting difficult. I use a kitchen scale for accuracy, but if you're measuring by volume, use a spatula to level off the batter in the bowl. Tap the pans gently on the counter after filling to remove air bubbles. Rotate the pans halfway through baking for even heat exposure.
Premature Frosting Application
Frosting warm cake creates condensation that makes the frosting slide off and can make the cake soggy. Always wait until the cakes are completely cool—at least 2 hours at room temperature. I've seen many beautiful cakes ruined by impatient frosting. For extra insurance, chill the frosting in the fridge for 10 minutes before applying to prevent melting.
Ignoring the Sour Cream
This ingredient is non-negotiable for moisture and tenderness. Skipping it or using low-fat versions results in a drier cake. Full-fat sour cream is ideal, but if you're watching calories, use ½ cup Greek yogurt instead. The fat content is what keeps the crumb ultra-moist. I've tested this recipe with substitutions, and nothing compares to the real thing for that signature texture. 🥛

Frequently asked questions
Why does this recipe use only 2 eggs instead of the usual 3?
This recipe achieves perfect texture through the creaming method and sour cream, which add moisture and structure without needing extra eggs. The cold butter creates air pockets that lighten the crumb, while the alternating dry/wet method prevents density. It's a science-backed approach that delivers the same rich flavor with fewer eggs!
Can I make this cake without sour cream?
You can substitute ½ cup Greek yogurt or ½ cup buttermilk, but the texture will be slightly less moist. The fat content in sour cream is key for that signature tender crumb. If you're avoiding dairy, try ½ cup coconut yogurt—just know it may alter the flavor slightly. Never skip the moisture source entirely!
How do I fix a cake that's cracked on top?
Cracking usually happens from uneven cooling or overbaking. Let the cake cool gradually in the pan for 10 minutes, then transfer to a wire rack. If cracks appear, cover them with extra frosting or decorate with fresh berries. For prevention, avoid opening the oven door early and check doneness with a toothpick at 25 minutes, not the timer.
What's the best way to store leftover cake?
Keep the cake in an airtight container at room temperature for up to 3 days. For longer storage, freeze the unfrosted layers for 3 months—thaw overnight in the fridge before adding frosting. Never freeze frosted cake, as moisture creates ice crystals. The frosting keeps separately in the fridge for 2 days.
Can I use this recipe for cupcakes?
Yes! Divide the batter into 12-14 greased cupcake liners (fill ⅔ full) and bake at 350°F for 18-20 minutes. The same frosting works perfectly—pipe it directly onto cooled cupcakes. For extra height, add a dollop of frosting to each cupcake before baking, then top with more frosting after cooling.
