Ingredients You'll Need

The magic of this cake starts with simple, trusted ingredients that each play an essential role. From the flour that forms the cake’s fluffy structure to the unsalted butter that enriches every bite, every ingredient is carefully chosen to bring out the best in this recipe.

• All-purpose flour (2 cups): Provides the perfect base for a soft and airy crumb; cake flour works well too for extra tenderness.
• Baking powder (2 ½ teaspoons): Makes sure the cake rises beautifully, giving it that light, fluffy texture we all love.
• Kosher salt (¼ teaspoon): Enhances flavor by balancing the sweetness and deepening the vanilla notes.
• Large eggs (4, room temperature): Eggs give structure and moisture; make sure they’re at room temp for optimal volume.
• Superfine sugar (1 ½ cups): Dissolves quickly to help the batter become airy and smooth.
• Unsalted butter (115g for batter, softened; 225g for frosting): Vital for flavor and richness in both the cake and the buttercream.
• Whole milk (1 cup): Adds moisture and tenderness while helping to create a smooth cake batter.
• Vanilla extract (3 teaspoons for cake, 3 teaspoons for frosting): The star flavor here — use the best quality you can find for a true vanilla punch.
• Vegetable or canola oil (3 teaspoons): Keeps the cake extra moist and soft for days.
• Powdered sugar (500g, sifted): Creates the classic sweet, silky buttercream to crown this beauty.
• Milk (2–4 tablespoons for frosting): Adjusts the buttercream consistency for spreading or piping perfection.

How to Make My Best Vanilla Cake - Moist and Fluffy with Classic Buttercream Frosting Recipe

Step 1: Preheat and Prepare Pans

Start by heating your oven to 180°C/350°F (160°C fan) so it’s perfectly hot when you’re ready to bake. Grease two 8-inch (20cm) cake pans with butter, then line the bottoms with parchment paper—this step ensures your cake layers release with ease, shaping the base for your masterpiece.

Step 2: Whisk Dry Ingredients

In a large bowl, sift together the flour, baking powder, and salt. This mix lays the foundation for the cake’s soft crumb. Sifting helps to incorporate air and removes lumps, giving you a smooth batter that will bake evenly.

Step 3: Beat Eggs and Sugar to Triple Volume

This step is where the cake’s incredible fluffiness begins. Using a stand mixer with a whisk attachment or a hand beater, beat the eggs on medium speed for about 30 seconds. Slowly add the superfine sugar over 45 seconds, then continue beating on high for about 7 minutes, or until the mixture triples in volume and turns pale and frothy. You’re building volume and lightness that will make your cake truly special.

Step 4: Melt Butter and Heat Milk

While your eggs are whipping away, gently melt the butter with the milk—either in the microwave or over the stove. This warm mixture will ensure the batter stays smooth and won’t deflate the air you’ve just whipped into the eggs.

Step 5: Combine Flour and Batter

Add the flour mixture to your whipped egg and sugar in three batches. Beat gently just long enough to incorporate each addition; over-mixing can toughen the cake. Once all the flour is in, you want to see no streaks but keep the air bubbles intact for perfect rise.

Step 6: Temper Warm Milk Mixture into Batter

Mix your hot milk, melted butter, vanilla extract, and oil in the bowl where you sifted the flour. Then, add about 1 ½ cups of the cake batter into this warm liquid, whisking vigorously to smooth out any lumps. Slowly pour this mixture back into the main batter while mixing gently on low speed. This method prevents curdling and keeps the batter silky smooth.

Step 7: Bake Your Cake

Divide the batter evenly between your prepared pans, about 560 grams each. Give each pan a few taps on the counter to release any large bubbles, which ensures an even crumb. Bake for around 30 minutes; your cake is done when golden on top and a toothpick inserted in the center comes out clean.

Step 8: Cool and Prepare Buttercream Frosting

Let the cakes cool in the pans for 15 minutes before gently inverting them onto wire racks. For level layers, cool the cakes upside down which helps flatten any dome naturally. Meanwhile, whip your buttercream by beating softened butter until it lightens to almost white and becomes fluffy—this step is key to that cloud-like texture. Gradually add sifted powdered sugar in three parts, beating well each time to avoid a sugar dust storm. Finish by mixing in vanilla and adjust the consistency with milk, keeping it soft enough to spread or pipe beautifully.

How to Serve My Best Vanilla Cake - Moist and Fluffy with Classic Buttercream Frosting Recipe

Garnishes

A lightly dusted surface of edible glitter or a scattering of fresh berries can elevate this classic vanilla cake to something truly stunning. Edible flowers or a few vanilla bean seeds sprinkled on the buttercream also add sophistication without overpowering the delicate vanilla flavor.

Side Dishes

This cake pairs wonderfully with a scoop of vanilla bean ice cream, seasonal fruit compote, or a dollop of freshly whipped cream. The creamy richness of these sides enhances the cake’s moist texture and adds a lovely contrast in temperature and flavor.

Creative Ways to Present

For celebrations, build a tiered cake with alternating layers of color or texture—for example, add thin layers of fruit jam or lemon curd between cake and frosting for a surprising twist. You can also pipe rosettes or ruffles around the sides using the buttercream, turning this simple cake into an elegant showstopper that’s sure to delight.

Make Ahead and Storage

Storing Leftovers

Once frosted, store your vanilla cake in an airtight container at room temperature for up to four days. This recipe’s moisture retention is impressive, and you’ll find even on day four it stays tender and delicious without drying out.

Freezing

You can freeze the cake layers before frosting by wrapping them tightly in plastic wrap and placing them in a sealed container or freezer bag. Freeze for up to three months. Thaw in the refrigerator overnight before frosting and serving, to enjoy that fresh-from-the-oven texture later on.

Reheating

If you want to revive a slice, warm it gently in the microwave for 15–20 seconds. The cake comes back soft and moist, and a little tip: serve with a fresh spoonful of buttercream or cream to mimic that perfect fresh-baked feel.

FAQs

Can I use cake flour instead of all-purpose flour?

Absolutely! Cake flour is great if you want an even lighter, softer crumb. Just remember to measure it correctly, and it will make your My Best Vanilla Cake - Moist and Fluffy with Classic Buttercream Frosting Recipe even more delicate.

How do I keep the cake moist for several days?

The combination of oil and butter along with proper storage keeps this cake moist for up to four days. Make sure to store the cake wrapped or in an airtight container to avoid drying out.

Can I make this cake dairy-free or vegan?

This recipe relies on butter, milk, and eggs for its texture and flavor, so substitutions would require some tweaks. For a dairy-free version, plant-based butters and milk might work, but the texture will change. Vegan adaptations need egg replacers and further testing to get that signature fluffiness.

What’s the easiest way to level cake layers?

Cooling the cakes upside down helps to flatten domes naturally. For precise layering, use a long serrated knife or cake leveler to trim off any uneven tops after cooling.

Can I make the frosting ahead of time?

Yes! You can prepare the buttercream a day ahead and refrigerate it. Before using, bring it to room temperature and beat it again for a minute or two to restore its fluffy texture, perfect for spreading or piping.

Cook Mode Prevent your screen from going dark

Instructions

1. Preheat Oven and Prepare Pans: Preheat your oven to 180°C (350°F), or 160°C (320°F) if using a fan-assisted oven. Allow the oven to heat for 20 minutes before baking. Grease two 20cm (8”) cake pans with butter and line the bottoms with parchment paper to prevent sticking.
2. Combine Dry Ingredients: In a large bowl, whisk together the flour, baking powder, and salt until evenly mixed. Set aside.
3. Beat Eggs and Sugar: Using a stand mixer fitted with a whisk attachment or a hand beater, beat the eggs on medium speed for 30 seconds to aerate. Gradually add the sugar over a 45-second period while continuing to beat. Then increase the speed and beat for 7 minutes until the mixture triples in volume and becomes thick and pale.
4. Heat Milk and Butter: In a heatproof jug, melt the butter with the milk either by microwaving on high for about 2 minutes or gently warming on the stovetop. This mixture will be hot but not boiling.
5. Add Flour to Batter: Add the dry flour mixture to the whipped egg and sugar in three batches. Beat briefly on low speed (about 5 seconds) after each addition until just combined and no flour streaks remain, being careful not to overmix.
6. Temper Milk Mixture: Pour the hot milk, vanilla extract, and oil into the empty flour bowl. Then add about 1 ½ cups (2 ladles) of the cake batter into the warm milk mixture, whisking vigorously until smooth and slightly foamy. Slowly pour this tempered milk mixture back into the main cake batter while mixing gently on low speed.
7. Final Mix: Scrape down the bowl’s sides and give the batter a final 10-second mix on low speed until smooth and pourable.
8. Fill Pans and Bake: Divide the batter evenly between the prepared cake pans (approximately 560g or 20 oz per pan). Tap the pans on the counter three times to remove large air bubbles. Bake in the preheated oven for about 30 minutes or until the cake is golden and a toothpick inserted into the center comes out clean.
9. Cool the Cakes: Remove the cakes from the oven and let them cool in their pans for 15 minutes. Then gently turn them out onto wire racks. If using as layered cakes, invert them while cooling to flatten any domed tops for even layers. Level the cakes if needed.
10. Prepare Vanilla Buttercream Frosting: In a stand mixer fitted with the paddle attachment, beat the softened butter on high speed for 3 minutes until light, creamy, and pale in color. Gradually add the sifted icing sugar in three portions, beating slowly to minimize dust, then beat on high for another 3 minutes until fluffy.
11. Finish Buttercream: Add vanilla extract and 2-4 tablespoons of milk to the buttercream. Beat for an additional 30 seconds. Adjust milk amount to achieve a soft yet pipeable consistency. Use immediately to frost the completely cooled cake layers. Store leftovers refrigerated and re-beat before use.

Notes

• Butter and milk should be hot but not boiling when tempered into the batter to avoid cooking the eggs prematurely.
• You can bake in two 20cm pans or three pans for thinner layers as preferred.
• Flatten domed cake tops by cooling cakes upside down for neat layering.
• If making ahead, refrigerate the buttercream and rewhip before using to restore fluffiness.
• This cake keeps moist for up to 4 days when stored in an airtight container at room temperature.
