Ingredients for all purpose cake
Twelve simple ingredients create a foolproof cake base for any celebration occasion.
| Ingredient | Amount | Notes |
|---|---|---|
| All-Purpose Flour 🌾 | 2 cups | Sifted for even texture |
| Granulated Sugar 🍚 | 1 ½ cups | White or light brown |
| Unsalted Butter 🧈 | 1 cup | Room temperature, cubed |
| Vegetable Oil 🫒 | ½ cup | Light or canola preferred |
| Large Eggs 🥚 | 2 whole | Room temperature for blending |
| Sour Cream 🥛 | ½ cup | Full-fat for moisture |
| Vanilla Extract 🌿 | 1 tbsp | Pure, not imitation |
| Baking Powder 🍃 | 2 tsp | Diamond Crystal preferred |
| Baking Soda 🧂 | ½ tsp | Aluminum-free |
| Salt 🧂 | ½ tsp | Fine sea salt |
| Milk 🥛 | ½ cup | Whole milk preferred |
| Cocoa Powder 🍫 | ⅓ cup | Optional for chocolate variation |
| Powdered Sugar 🍚 | ½ cup | For dusting or frosting |
The flour and sugar duo forms the foundation, so King Arthur or Gold Medal brands deliver consistent results. Butter and oil work together—room temperature butter ensures smooth mixing, while oil adds moisture without altering texture. For sour cream, full-fat works best—it's the secret to that signature tenderness. Eggs should be room temperature when measured; cold eggs can cause uneven mixing. The vanilla extract is non-negotiable here—imitation extracts lack the depth needed for professional results.
No sour cream? Plain Greek yogurt at half the quantity works in a pinch, though texture may vary slightly. Running short on butter? Applesauce at equal measure maintains moisture but reduces richness. For chocolate variations, Dutch-process cocoa powder creates a smoother finish than natural cocoa. The milk can be swapped for evaporated milk or buttermilk—both add subtle flavor variations. When measuring baking powder and soda, use the spoon-and-level method for accuracy, especially with Diamond Crystal brands which are lighter than others.
Store cake layers wrapped in plastic wrap at room temperature for up to 3 days or refrigerate for 5 days. For longer storage, freeze layers individually for 2 months—thaw at room temperature before frosting. The powdered sugar keeps indefinitely in an airtight container, while butter and oil should be refrigerated after opening. For best results, bake the cake day-of-serving to maintain peak texture and moisture.

Step-by-step instructions for all-purpose cake
This method delivers consistently moist, tender layers every time—ideal for birthdays, celebrations, or everyday treats.
Prepare Your Mixing Tools and Ingredients
Preheat your oven to 350°F and grease two 8-inch round cake pans with vegetable oil, then line the bottoms with parchment paper. Sift together the 2 cups all-purpose flour, 2 teaspoons baking powder, ½ teaspoon baking soda, and ½ teaspoon salt in a medium bowl. Set aside—this ensures a light, even texture without lumps.
In a separate large bowl, beat the 1 cup unsalted butter and 1.5 cups granulated sugar on medium speed with an electric mixer until light and fluffy, about 3-4 minutes. This creaming process incorporates air, which creates the cake's signature tenderness. Scrape down the sides of the bowl occasionally to ensure even mixing.
Combine Wet Ingredients for Maximum Moisture
Add the 2 whole large eggs, one at a time, mixing well after each addition until fully incorporated. The mixture should be thick and pale. Stir in the 1 tablespoon vanilla extract and ½ cup sour cream, mixing until smooth. The sour cream adds moisture and richness without altering the cake's structure.
Gradually pour in the ½ cup milk while mixing on low speed, then add the dry ingredients in three parts, alternating with the ½ cup vegetable oil. Mix just until combined—overmixing develops gluten, which can make the cake dense. Stop mixing as soon as the batter is homogeneous and no dry spots remain.
Fold in Cocoa Powder (Optional) for Chocolate Variation
If making a chocolate version, gently fold in the ⅓ cup cocoa powder using a spatula until evenly distributed. For a vanilla cake, skip this step. The batter should be thick but pourable. If it appears too stiff, add 1-2 tablespoons milk to achieve a smooth consistency.
Divide the batter evenly between the prepared pans, smoothing the tops with a spatula. Tap each pan gently on the counter to release any air bubbles. Bake for 25-30 minutes, or until a toothpick inserted into the center comes out clean. Rotate the pans halfway through baking for even browning.
Cool and Finish for Perfect Texture
Remove the cakes from the oven and let them cool in the pans for 10 minutes. Transfer to a wire rack to cool completely. Once cooled, dust the tops with ½ cup powdered sugar for a classic finish or prepare your favorite frosting. For extra moisture, brush the warm layers with simple syrup or a light glaze.
This cake's versatility comes from its balanced structure—moist yet sturdy enough for layering or slicing. Store leftovers in an airtight container at room temperature for up to 3 days or freeze for longer storage. The secret to its success lies in precise mixing and the right ratio of fat to liquid ingredients.
Pro Tips For Making All Purpose Cake
- Melt Butter Slowly: I learned this the hard way—dumping cold butter into hot sugar makes a greasy mess. Instead, cut the butter into small cubes and let it melt just until it turns liquid but still holds its shape. This keeps the texture tender without making the batter greasy.
- Weigh Your Flour: Scooping flour from the bag packs in air, and that’s how you end up with a dense cake. Use a kitchen scale for precision—1 cup of all-purpose flour is about 125 grams, not the 140 grams you’d scoop. Your cake will rise better and stay light.
- Skip the Overmixing: Once you add the eggs, mix just until combined—no streaks, no lumps, but don’t beat it like a smoothie. Overworking the batter develops gluten, and that’s how you get a tough, chewy cake instead of a soft one.
- Room-Temp Eggs Matter: Cold eggs won’t blend smoothly, and you’ll end up with streaks in the batter. Take them out of the fridge 30 minutes before mixing—this ensures they whip up evenly and distribute fat and sugar properly. (Yes, even if you’re impatient like me.)
Essential equipment for this dish
Mixing Essentials
Start with a stand mixer or hand mixer—I recommend the KitchenAid Artisan Series for its power and durability. For budget-friendly options, the Cuisinart SM-50 delivers consistent results. The medium mixing bowl should be large enough to hold all ingredients without spilling during creaming. 🥣
Baking Pans
Use 8-inch round cake pans with 2-inch tall sides for even baking. I prefer Wilton Perfect Results pans—they release cakes easily without sticking. Grease pans thoroughly with vegetable oil and line the bottoms with parchment paper for foolproof removal. For sheet cakes, a half-sheet pan (13x9 inches) works perfectly.
Measuring Tools
Accurate measurements are critical—use a digital kitchen scale for dry ingredients like flour and sugar. For liquids, a liquid measuring cup with clear markings prevents spills. The spoon-and-level method ensures consistent baking powder and soda measurements, especially with Diamond Crystal brands which are lighter than others. 📏
Cooling Rack
A wire cooling rack prevents soggy bottoms by allowing air circulation. I keep a stainless steel rack from OXO in my kitchen—it's durable and easy to clean. Place the rack directly on the counter to cool cakes completely before frosting, which prevents melting.
Optional Tools
For chocolate variations, a small offset spatula helps fold in cocoa powder smoothly. A toothpick tests doneness, while a pastry brush applies simple syrup for extra moisture. For decorating, a powdered sugar sifter creates a flawless finish. These extras elevate presentation without being essential. ✨

Frequently asked questions
Can I make this cake without sour cream? Yes! If you don't have sour cream, substitute with ½ cup plain Greek yogurt or ½ cup buttermilk. For a slightly lighter texture, use ½ cup evaporated milk**
—just note the flavor may differ slightly. The key is maintaining moisture, so avoid dairy-free substitutes like almond milk, which won't provide the same richness.
How do I adjust this recipe for a sheet cake?
For a 13x9-inch half-sheet cake, increase batter to 10-12 cups total (about 2.5x the original). Bake at 350°F for 25-30 minutes, testing with a toothpick. Spread batter evenly in the pan and use a spatula to create a smooth surface.
Why did my cake turn out dense?
Overmixing the batter develops gluten, making cakes tough. Mix just until combined—stop when no dry spots remain. Also check your baking powder (use fresh) and ensure eggs/butter are room temperature. A toothpick test confirms doneness—if it comes out clean, the cake is ready.
Can I bake this cake in a glass pan?
Yes, but reduce oven temperature by 25°F (to 325°F) and bake for 5-10 minutes longer. Glass conducts heat differently, so monitor closely. Grease the pan thoroughly and use parchment paper to prevent sticking. Glass pans may require slightly less baking time than metal.
What’s the best way to store leftover cake?
Wrap layers tightly in plastic wrap and store at room temperature for up to 3 days or refrigerate for 5 days. For longer storage, freeze layers individually for 2 months. Thaw overnight in the fridge before frosting. Avoid storing frosted cakes in the fridge—humidity causes condensation.
