Ingredients for all in one cake

Eight simple ingredients for a foolproof cake—no measuring cups left behind.

The flour and baking powder are your foundation here. King Arthur or Gold Medal flour works best for that tender crumb, but don't stress if you've got the basics. The butter needs to be room temperature—no cold chunks, no melted puddle. I always grab Land O'Lakes unsalted from the grocery store, but any brand works. For the vanilla, pure extract (not imitation) makes all the difference—trust me, your cake will taste it. The powdered sugar is optional, but I keep it handy for that final elegant touch. Pro tip: zest your lemon fresh—it brightens the whole cake.

No vanilla extract? Almond extract at half the amount works in a pinch, though it'll taste different. Short on butter? Applesauce or Greek yogurt can replace half, but your cake might be denser. Want chocolate? Swap half the milk for espresso powder mixed with hot water—deepens the flavor. The cocoa powder is a game-changer for chocolate lovers, but skip it for vanilla. If you're baking at high altitude, add 0.25 tsp more baking powder. And for the love of cake, don't overmix—just combine until flour disappears.

This batter keeps for 2 days in the fridge, covered. For longer storage, freeze the batter in an airtight container for up to 3 months3 days or freeze slices for 2 months. The powdered sugar topping? Use a fine-mesh sieve for that perfect dusting. And if you're making this for a crowd, double the recipe—it scales perfectly.

Step-by-step instructions for all-in-one cake mix-and-bake magic

Here's how to make this foolproof cake with zero fuss—just mix, pour, and bake.

Start by sifting the 2 cups all-purpose flour and 2 teaspoons baking powder together in a medium bowl. This removes lumps and ensures your cake rises evenly. In a separate large bowl, measure out the 1.5 cups granulated sugar, 1 cup unsalted butter (cut into small cubes if cold), 2 whole large eggs, 1 cup milk, 1 tablespoon vanilla extract, 0.5 teaspoon salt, and 0.25 cup vegetable oil. Room-temperature ingredients mix better, so if your butter feels chilled, let it sit at room temperature for 10-15 minutes before starting.

For the lemon twist, grate 1 tablespoon lemon zest using a fine grater. If you're making the chocolate variation, sift the 0.25 cup cocoa powder into the dry ingredients now. The zest adds brightness, while the cocoa deepens the flavor—both blend seamlessly into the batter.

In your large bowl, beat the 1 cup unsalted butter and 1.5 cups granulated sugar together using an electric mixer on medium speed for 3-4 minutes. You’ll know it’s ready when the mixture is light, fluffy, and nearly doubles in volume. This step aerates the batter, giving your cake that classic tender crumb.

Add the 2 whole large eggs, one at a time, mixing well after each addition. Then pour in the 1 cup milk, 1 tablespoon vanilla extract, 0.5 teaspoon salt, and 0.25 cup vegetable oil. Mix on low speed for 1 minute until fully combined. The batter should be smooth with no streaks of flour—this ensures a uniform texture throughout.

With the mixer on low speed, gradually add the sifted dry ingredients (flour, baking powder, and cocoa powder if using) to the wet mixture. Mix just until combined—no more than 30 seconds—to avoid overmixing, which can make the cake dense. If you’re using lemon zest, fold it in by hand at the end to preserve its bright flavor.

For an extra touch, sprinkle 0.5 cup powdered sugar over the batter and gently fold it in. This adds a delicate sweetness without altering the cake’s structure. The batter should be thick but pourable—like heavy pudding. If it’s too stiff, add 1-2 tablespoons milk to loosen it.

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 pan and smooth the top with a spatula. Bake for 30-35 minutes, or until a toothpick inserted into the center comes out clean. The edges should be golden brown, and the top should spring back slightly when pressed gently.

I like to tent the pan with foil after 20 minutes to prevent overbrowning, especially if your oven runs hot. Once done, let the cake cool in the pan for 10 minutes, then transfer it to a wire rack to cool completely. This resting period keeps the cake from cracking as it cools.

Slice the cake into 8 equal servings and dust the top with an extra sprinkle of powdered sugar for a bakery-style finish. Serve warm or at room temperature—either way, it’s a crowd-pleaser. The secret to this cake’s magic? The single-bowl method keeps everything simple while delivering a moist, flavorful result every time.

Pro tip: If you’re short on time, this cake bakes up beautifully in 25 minutes for a slightly denser texture, or 40 minutes for a taller, lighter cake. Adjust based on your preference!

Troubleshooting this recipe

Cake Stuck in Pan

If your cake refuses to release from the pan, don’t panic—this happens when the batter overbakes or the pan isn’t properly prepared. First, ensure you greased your 8-inch round pan with butter or baking spray (I swear by Baking King brand) and lined it with parchment paper. If it’s still stuck, run a thin offset spatula or dull knife around the edges while the cake is still warm. For stubborn cases, invert the pan onto a cooling rack and gently tap the sides—gravity will do the work. 💡

Dense or Gummy Texture

A dense or gummy cake usually means overmixing or incorrect baking time. Mix the batter just until the dry ingredients disappear—no more than 30 seconds on low speed. Also, check your oven temperature with an oven thermometer (I use Thermoworks); if it’s running hot, reduce the heat to 325°F. For gummy centers, bake for 5-10 extra minutes until a toothpick comes out clean. If the cake is still underdone, broil it for 1-2 minutes to finish.

Uneven Rise or Sinking Middle

An uneven rise often happens when the oven isn’t preheated long enough or the batter isn’t mixed properly. Always preheat your oven for at least 15 minutes before baking. For a sinking middle, ensure your baking powder is fresh (old baking powder loses potency). If the cake starts to sink after baking, it’s likely overmixed or underbaked. Try placing the pan on the middle rack (not the top) for even heat distribution. 🌡️

Cracked Top or Sides

Cracks usually appear when the cake cools too quickly or the oven isn’t hot enough. Let the cake cool in the pan for 10-15 minutes before transferring it to a wire rack. If cracks are a recurring issue, try baking at 325°F instead of 350°F for a slower rise. For a smooth finish, brush the top with simple syrup (equal parts sugar and water) right after baking—it seals the surface and prevents drying.

Bitter or Off Taste

A bitter taste often means your butter or milk was left out too long or your vanilla extract went bad. Always use fresh ingredients, especially dairy and extracts. If you suspect the vanilla, replace it with almond extract (use half the amount) as a temporary fix. For a metallic taste, check your baking powder and salt—old leavening agents can turn your cake bitter. Store spices and extracts in a cool, dark place to preserve freshness.

Batter Too Thin or Too Thick

If your batter is too thin, add 1-2 tablespoons of all-purpose flour to thicken it. For a thicker batter, mix in 1-2 tablespoons of milk to loosen it. The ideal consistency should be like heavy pudding—thick enough to pour but not stiff. If the batter separates, whisk it gently until smooth. For extra insurance, sift the dry ingredients again before mixing to avoid lumps. 🥄
