Ingredients for 8 inch single layer cake
Pantry staples meet precision technique for a flawless single-layer cake every time.
| Ingredient | Amount | Notes |
|---|---|---|
| All-Purpose Flour 🌾 | 2 cups | Sifted, spooned and leveled |
| Unsalted Butter 🧈 | 1 cup | Cold, cubed, room temperature |
| Granulated Sugar 🍚 | 1 ½ cups | Superfine preferred for smoothness |
| Large Eggs 🥚 | 2 whole | Room temperature, separated |
| Vanilla Extract 🌿 | 2 tsp | Pure, high-quality extract |
| Baking Powder 🧂 | 2 tsp | Diamond Crystal preferred |
| Salt 🧂 | ½ tsp | Fine sea salt |
| Whole Milk 🥛 | ½ cup | Room temperature |
| Powdered Sugar 🍚 | 2 cups | For buttercream |
| Heavy Whipping Cream 🥛 | 1 cup | Cold, full-fat preferred |
| Vanilla Bean Paste 🌿 | 1 tsp | For enhanced flavor |
| Cake Flour 🌾 | 1 cup | Optional for lighter texture |
| Cocoa Powder 🍫 | ⅓ cup | For chocolate variation |
| Vegetable Oil 🫒 | ¼ cup | For moisture, optional |
The flour choice is pivotal—all-purpose delivers structure while cake flour (if using) ensures a lighter crumb. King Arthur or Gold Medal brands are ideal for consistent results. For the butter, Plugrá or Land O’Lakes unsalted sticks work best when cold-cubed, ensuring proper creaming. Superfine sugar dissolves more smoothly, but regular granulated works if sifted first. Eggs should be separated only if making Swiss meringue buttercream, otherwise use whole eggs at room temperature for even mixing. Diamond Crystal baking powder is slightly lighter than others—measure carefully. The milk should be room temperature to blend seamlessly into the batter.
No cake flour? Substitute with all-purpose by removing 2 tbsp from the total and adding 2 tbsp cornstarch. Butter shortages? Replace with vegetable shortening (though texture may differ slightly). Vanilla extract can be swapped for vanilla bean paste or even 1 tsp vanilla sugar in a pinch. For the buttercream, powdered sugar can be replaced with superfine sugar (add 1 tbsp extra liquid). Heavy whipping cream must be cold—microwave it 20 seconds if too soft. The cocoa powder should be natural (not Dutch-process) for vibrant color and rich flavor. Vegetable oil adds moisture but can be omitted for a lighter cake.
Store cake layers in an airtight container at room temperature for up to 3 days or refrigerated for 5 days. Buttercream should be refrigerated between uses and rewhipped to fluffiness. For longer storage, freeze layers wrapped in plastic for up to 2 months—thaw at room temperature before frosting. Room-temperature cake slices beautifully, while chilled layers hold their shape better for stacking. Freshly baked is ideal, but a light glaze can revive slightly dried layers.

Step-by-step instructions for one-bowl single layer cake
Here's how to create a perfectly moist cake with minimal effort and maximum flavor.
Prepare Your Mixing Bowl and Ingredients
Begin by sifting together the 2 cups All-Purpose Flour, 2 tsp Baking Powder, and 0.5 tsp Salt in a large mixing bowl. This ensures even distribution and prevents lumps in your batter. I like to use a fine-mesh sieve for this step—it creates a lighter texture in the final cake.
In a separate bowl, whisk together the 1 cup Unsalted Butter (cold, cubed) and 1.5 cups Granulated Sugar until light and fluffy. This creaming process incorporates air into the mixture, which helps create that signature tender crumb. You'll know it's ready when the mixture nearly doubles in volume and becomes pale in color—this usually takes about 3-4 minutes using an electric mixer on medium speed.
Combine Wet Ingredients for Perfect Texture
Add the 2 whole Large Eggs (room temperature) one at a time to the butter-sugar mixture, mixing well after each addition. Then stir in the 2 tsp Vanilla Extract and 0.5 cup Whole Milk. The eggs provide structure while the milk adds moisture without making the cake too dense.
Here's where the magic happens: slowly add the dry flour mixture to the wet ingredients in three equal parts, mixing just until combined after each addition. Overmixing develops gluten and can result in a tough cake, so stop as soon as the batter comes together. The final batter should be smooth with no visible flour streaks.
Bake to Golden Perfection
Preheat your oven to 350°F and grease an 8-inch round cake pan. 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. The edges should be golden brown, and the cake should spring back slightly when gently pressed in the center.
I've found that baking times can vary slightly based on your oven, so start checking at the 20-minute mark. If the top browns too quickly, tent the pan with aluminum foil to prevent over-browning while allowing the center to finish cooking.
Prepare the Buttercream Filling (Optional)
While the cake cools, prepare the buttercream by beating the 1 cup Heavy Whipping Cream (cold) to soft peaks. Gradually add the 2 cups Powdered Sugar and 1 tsp Vanilla Bean Paste, mixing until smooth and fluffy. For a chocolate variation, sift in the 0.33 cup Cocoa Powder and mix until fully incorporated.
For an even lighter texture, you can substitute 1 cup Cake Flour for 1 cup of the All-Purpose Flour in the cake batter. This creates a more delicate crumb that pairs beautifully with the rich buttercream. The cake flour also helps absorb excess moisture, keeping your cake tender rather than gummy.
Assemble and Serve
Once the cake has cooled completely, spread the buttercream evenly over the top of the cake. For extra elegance, you can pipe decorative borders or swirls using a pastry bag fitted with a star tip. The cake will keep well at room temperature for 2-3 days when stored in an airtight container.
This single layer cake serves 8 and is perfect for intimate gatherings or as a showstopping centerpiece. The one-bowl method makes it incredibly easy to prepare, while the combination of buttercream and moist cake creates a harmonious balance of textures and flavors.
Pro Tips For Making 8 Inch Single Layer Cake
- Weigh Your Butter: I learned this the hard way—packed butter weighs more than scooped butter, and that tiny difference throws off the whole recipe. Use a kitchen scale for 8 ounces (225g) of cold, cubed butter, then press it into the flour mixture with your fingers to distribute it evenly.
- Stop When the Center Jiggles: Your cake is done when it springs back slowly when touched—not when it’s golden brown. An 8-inch cake needs about 25-30 minutes at 350°F (175°C), but pull it out when the edges pull away from the pan and the center moves like Jell-O. Overbaking dries out the crumb, and nobody wants that.
- Sift the Flour Twice: I skip this when I’m lazy, but the dish is noticeably better when I don’t. First sift the flour with salt and leavening (if using) to aerate it, then sift it again right before mixing. This keeps the batter light and prevents dense pockets—critical for a single-layer cake where texture matters most.
- Chill the Batter 10 Minutes: Sounds weird, but it works: Let the mixed batter sit uncovered in the bowl for 10 minutes before pouring. This relaxes the gluten in the flour, which prevents cracking and gives you a smoother crumb. (Yes, even if you’re impatient like me.)
Perfect pairings for 8 inch single layer cake
Buttercream Variations
Swap the classic vanilla buttercream for chocolate ganache by melting ½ cup heavy cream with 6 oz dark chocolate (70% cocoa), then spreading while still warm.
For a lighter option, try Swiss meringue buttercream—whisk ½ cup egg whites and ½ cup sugar over a double boiler until 160°F, then whip with ½ cup softened butter. Both options add rich depth while keeping the cake's elegance. 🍫
Fruit Toppings
Fresh berries like raspberries or blackberries add vibrant color and acidity that cuts through the richness. Arrange them in a circular pattern on top of the buttercream for a polished look.
For a tropical twist, use mango slices or passion fruit pulp—simmer ½ cup pulp with 1 tbsp sugar for 5 minutes to make a glossy drizzle. 🍓
Whipped Cream Finish
Pipe lightly sweetened whipped cream around the edges of the cake for a restaurant-style presentation. Fold in 1 tsp vanilla extract and 1 tbsp powdered sugar for stability. Top with toasted coconut flakes or crushed pistachios for texture contrast. This works especially well with the vanilla cake flavor. ✨
Chocolate Drizzle
Melt 4 oz white chocolate with 2 tbsp coconut oil for a smooth drizzle over the buttercream. For extra flair, add edible gold leaf or crushed pretzels before the chocolate sets. This technique elevates the cake for special occasions without extra effort. 💛
Citrus Zest Glaze
Combine ½ cup powdered sugar, 2 tbsp lemon juice, and 1 tsp orange zest for a bright, glossy finish. Drizzle over the cake while it’s still slightly warm to help it set. This glaze pairs beautifully with vanilla or carrot cake flavors. 🍋
Caramel Sauce Pairing
Warm ½ cup heavy cream with ½ cup granulated sugar until caramelized, then thin with 1 tbsp water**. Drizzle over the cake or serve on the side for dipping. The sweet-salty contrast enhances chocolate or spice cakes. 🍯

Frequently asked questions
Can I make this recipe without an electric mixer?
Use a sturdy wooden spoon or whisk to cream the butter and sugar until light and fluffy—this takes about 5-7 minutes of vigorous mixing. For the flour mixture, fold it in gently by hand using a spatula, being careful not to overmix. The key is patience and consistent strokes to achieve the same airy texture.
Why did my cake crack on top?
Cracking often happens when the oven is too hot or the cake bakes too quickly. Preheat your oven for 15 minutes and avoid opening the door while baking. If the top browns too fast, tent the pan with foil. Also, ensure your butter and eggs are at room temperature—they blend more evenly and prevent sudden temperature shifts in the batter.
How do I adjust this recipe for a chocolate cake?
Replace 1 cup of the all-purpose flour with ⅓ cup cocoa powder (sifted) and add 2 tbsp extra milk to balance the dryness. For deeper flavor, swap the vanilla extract with 1 tsp espresso powder or 1 tbsp instant coffee granules. The buttercream can also be transformed into chocolate by adding ⅓ cup cocoa powder to the recipe.
Can I bake this cake in a different-sized pan?
Yes, but adjust the baking time. For a 9-inch pan, reduce the oven temperature to 325°F and bake for 20-25 minutes. For an 8-inch pan, stick to 350°F for 25-30 minutes. Always check for doneness with a toothpick. The batter volume stays the same, so a larger pan will yield a thinner cake.
What’s the best way to store a leftover cake?
Keep the cake in an airtight container at room temperature for up to 3 days. For longer storage, refrigerate it (covered) for 5 days or freeze the unfrosted layer for 2 months. To revive a slightly dried cake, brush the top with simple syrup (½ cup water + ½ cup sugar, heated until dissolved) before serving.
