This basic one-egg cake recipe delivers the perfect balance of light-as-air texture and golden crust—all with just one egg. The secret lies in proper mixing techniques and precise baking to create a tender crumb without overworking the batter. I developed this recipe after years of perfecting minimal-egg baking, making it ideal for those who want rich results without excess. The beauty of this recipe is its simplicity: five core ingredients create a foolproof foundation. Whisking the egg and sugar until pale and thick is critical—this step builds the cake's signature lift. A touch of baking powder ensures that rise, while melted butter keeps the texture moist. The result? A cake that's delicate yet sturdy enough to hold light frosting. By the time it emerges from the oven, you'll have a cake with a golden, crackly crust and a tender, even crumb that practically melts in your mouth. The flavor is clean and buttery, providing the perfect blank canvas for vanilla frosting, fresh berries, or even a dusting of powdered sugar. This is the kind of cake that proves good things come in small packages. Perfect for practice bakers or those with limited ingredients, this recipe scales easily for cupcakes or layer cakes. Let's get baking!
Ingredients for basic 1 egg cake
Five simple ingredients transform into a cloud-light cake with golden perfection.
| Ingredient | Amount | Notes |
|---|---|---|
| Large Egg 🥚 | 1 whole | Room temperature preferred |
| Granulated Sugar 🍚 | ¾ cup | White or light brown |
| All-Purpose Flour 🌾 | 1 cup | Sifted for lightness |
| Unsalted Butter 🧈 | ½ cup | Melted and cooled slightly |
| Baking Powder 🍞 | ½ tsp | Metal or electric measuring spoons |
| Salt 🧂 | ¼ tsp | Fine sea salt preferred |
| Vanilla Extract 🌸 | ½ tsp | Pure vanilla preferred |
| Whole Milk 🥛 | ¼ cup | Room temperature for best mixing |
The egg is your golden ticket here—room temperature is key for even mixing. Grab a large egg from the carton (the ones labeled 'large' aren't always uniform, so check the weight). For sugar, Domino or C&H brands work perfectly—they're finely ground and dissolve smoothly. Flour? King Arthur or Bob's Red Mill are my go-tos for baking; they're sifted and consistent. The butter matters too—Land O'Lakes unsalted melts beautifully, but any good-quality brand will do. Pro tip: melt it in the microwave for 40 seconds, then let it cool slightly before mixing. That way, you won't scramble the egg.
No vanilla extract? Vanilla bean paste works in a pinch, or even vanilla sugar (use half the amount). Short on milk? Almond milk or heavy cream both work, but whole milk gives that classic cake texture. The baking powder is non-negotiable—double-check the expiration date (old baking powder won't rise). For salt, Diamond Crystal is my favorite, but any fine sea salt will do. If you're making this for cupcakes, reduce the baking powder to 0.25 tsp—cupcakes bake faster and need less lift. And trust me, don't skip the whisking step—that egg and sugar need to be pale and thick for that signature airy texture.
This batter keeps in the fridge for up to 2 days, covered tightly. For longer storage, portion into cupcake liners and freeze—bake straight from frozen, adding 2-3 minutes. The cake itself? Best eaten fresh, but slices well for 3-4 days in an airtight container. I always bake mine in a 9-inch round pan for a single layer, but you can stack two for a classic two-layer cake. Leftovers? Toast slices lightly for a buttery treat—it's like cake French toast, but better.

Step-by-step instructions for a light-as-air one-egg cake
Here's how to create a perfectly tender, golden-crusted cake with just one egg—simple but impressive!
Melt and Cool the Butter
Place the 0.5 cup unsalted butter in a microwave-safe bowl and melt it in 30-second bursts on medium power, stirring between each interval. This prevents burning. Once fully melted, let it cool for 5-7 minutes until it reaches about 100°F—warm to the touch but not hot. This cooled butter blends more smoothly with the egg and prevents a dense cake.
I like to test the temperature by touching the back of my hand—it should feel warm but not scalding. If it's still too hot, place the bowl in an ice bath for 1-2 minutes to cool faster. This step is crucial for achieving that light, airy texture without overmixing the batter later.
Whisk Egg and Sugar Until Pale and Fluffy
In a large mixing bowl, combine the 1 whole large egg and 0.75 cup granulated sugar. Using a hand mixer or stand mixer with the whisk attachment, beat on medium-high speed for 3-4 minutes until the mixture is pale yellow, thick, and ribbony when the whisk is lifted. This process incorporates air, which helps create that signature light-as-air rise.
You'll notice the mixture nearly doubles in volume and becomes glossy. If you're using room-temperature egg, it will blend more easily—this is why I always recommend taking the egg out of the fridge 30 minutes before starting. Stop mixing once the sugar fully dissolves and the batter looks smooth and fluffy.
Alternate Adding Dry and Wet Ingredients
Reduce the mixer speed to low and add one-third of the 1 cup all-purpose flour along with the 0.5 tsp baking powder and 0.25 tsp salt. Mix just until combined, then add half of the 0.25 cup whole milk. Repeat this process: add another third of the flour mixture, then the remaining milk, and finish with the last third of flour. This alternating method prevents lumps and ensures even distribution.
After adding all the flour, mix on low speed for another 30 seconds until just combined—you should still see a few dry spots. Overmixing develops gluten, which can make the cake tough. Scrape down the sides of the bowl with a spatula to ensure everything is evenly incorporated.
Fold in Vanilla and Melted Butter
Add the 0.5 tsp vanilla extract to the batter and mix on low speed for 10 seconds until fully combined. Then, gradually pour in the cooled melted butter while mixing on low speed for 1 minute until smooth. The batter should be thick but pourable—like heavy pudding. If it looks too stiff, add 1 tablespoon of milk to loosen it.
This is where the magic happens—the butter adds moisture and richness while keeping the cake tender. The vanilla infuses throughout, giving a subtle but noticeable depth of flavor. Give the batter one final stir with a spatula to ensure everything is evenly distributed before pouring into the pan.
Bake Until Golden and Springy
Preheat your oven to 350°F and grease an 8-inch round cake pan or line it with parchment paper. Pour the batter into the prepared pan and smooth the top with a spatula. Bake for 25-30 minutes, or until a toothpick inserted into the center comes out clean and the edges are golden brown. The cake should also spring back slightly when gently pressed in the center.
I always check for doneness at the 25-minute mark—every oven runs hot or cold, so start testing early. If the top browns too quickly, tent the pan with aluminum foil to prevent over-browning while the center finishes baking. Let the cake cool in the pan for 10 minutes, then transfer to a wire rack to cool completely before serving.
Pro Tips For Making Basic 1 Egg Cake
- Melt Butter Slowly: If your butter’s still cold when you mix it into the egg and sugar, you’ll end up with a cake that’s dense and greasy. Microwave the butter in 10-second bursts until it’s just liquid—no bubbles, just smooth—and let it cool for 30 seconds before adding it. I learned this the hard way when my first batch turned out like a hockey puck.
- Sift the Flour Twice: That baking powder isn’t doing its job if it’s clumped in the flour. Sift the dry ingredients together first, then sift them again right before folding them into the wet mix. Yes, it takes 30 seconds extra, but it guarantees a lighter crumb. (Your future self will notice the difference.)
- Don’t Overmix the Batter: As soon as the flour disappears into the egg mixture, stop stirring. I used to think more mixing = better texture, but this recipe only needs a gentle fold until just combined. Overmixing means a tough, chewy cake instead of the tender crumb you’re after.
- Use Room-Temp Egg: Cold eggs make the batter thicker and can cause the cake to sink in the middle. Take the egg out of the fridge 10 minutes before cracking it into the sugar—just long enough to warm up to room temperature. It’s a small step, but it makes the cake rise more evenly. (I know, I know, but trust the process.)
Make-ahead tips for this basic 1 egg cake
Prep Ahead
Mix the batter up to 2 days ahead and store it in an airtight container in the fridge. When ready to bake, let it sit at room temperature for 30 minutes before pouring into your pan. This gives the ingredients time to meld, and the cake will bake beautifully without any adjustments. I love using this trick for weekend baking—just whip up the batter on Friday and bake fresh on Saturday. 📅
Freezer-Friendly
For longer storage, pour the batter into greased cupcake liners or a 9-inch round pan and freeze for up to 1 month. When ready to bake, remove from the freezer and bake straight from frozen, adding 5-7 extra minutes to the baking time. This works especially well if you're making cupcakes—just pop them in the oven whenever you're craving a treat. 🧊
Double the Batch
This recipe scales perfectly for a two-layer cake! Double the ingredients and bake in two 8-inch round pans simultaneously. Use the same baking time, but check for doneness at 22 minutes since ovens can vary. Once cooled, layer with your favorite frosting—vanilla buttercream or whipped cream both work beautifully. I often make two batches for parties so I have extra slices for leftovers. 🎂
Make Cupcakes
Divide the batter evenly among 12 greased cupcake molds or liners. Bake at 350°F for 18-20 minutes, or until a toothpick comes out clean. Cupcakes bake faster than a full cake, so keep an eye on them after 15 minutes. Top with a dollop of frosting or a sprinkle of powdered sugar for a quick, individual-sized dessert. These are perfect for lunchboxes or last-minute gatherings. 🧁
Storage Secrets
Once baked, store the cake in an airtight container at room temperature for up to 3 days. For longer storage, slice and freeze individual portions on a tray before transferring to a freezer bag. Reheat slices in the microwave for 10-15 seconds to restore freshness. I often slice the cake into 1-inch thick rounds for easy portioning and reheating. 💡
Reheating Tips
For a crispy crust and warm center, reheat slices in a 350°F oven for 5-7 minutes on a wire rack. This method keeps the cake moist while giving it a fresh-from-the-oven texture. If you're short on time, the microwave works too—just cover the slice with a damp paper towel and heat for 10 seconds. Avoid over-heating, or the cake may become gummy. 🔥

Frequently asked questions
Why does this cake recipe use only one egg?
This recipe uses just one egg to create a delicate, tender crumb without overpowering the flavor. The secret lies in proper whisking and precise baking techniques—whipping the egg and sugar until pale and thick incorporates air, giving the cake lift. It's perfect for those who want rich results with minimal ingredients or want to practice baking with fewer eggs.
Can I substitute the milk in this recipe?
Yes! You can use almond milk, heavy cream, or even buttermilk in a 1:1 ratio. Whole milk is recommended for the classic texture, but plant-based milks work well for a lighter version. If using buttermilk, reduce the baking powder to 0.25 tsp since it adds acidity.
What if my cake turns out dense instead of light? Dense cake usually means overmixing the batter or using hot butter.
How do I make this into cupcakes?
Divide the batter evenly among 12 greased cupcake liners and bake at 350°F for 18-20 minutes. Cupcakes bake faster than a full cake, so start checking at 15 minutes. Top with frosting or powdered sugar for a quick treat. This recipe makes 12 cupcakes with the same ingredients.
Can I add mix-ins like chocolate chips or fruit?
Yes, but keep it simple! Fold in 0.5 cup of chocolate chips or chopped nuts after adding the flour, mixing just until combined. Avoid adding too many mix-ins, or the cake may become dense. For fruit, use 0.5 cup finely chopped berries and fold them in gently.
