Classic Vanilla Layer Cake with Vanilla Buttercream Frosting

This recipe will guide you through making a perfectly moist and tender vanilla cake, layered with a luscious vanilla buttercream. It's an ideal choice for birthdays, celebrations, or simply to brighten any day.

Yields: 1 (8-inch/20cm), 2-layer cake | Prep time: 30 minutes | Bake time: 25-30 minutes | Chill time: 30 minutes | Total time: Approx. 2 hours

Ingredients for the Vanilla Cake Layers:

2 ½ cups (300g) All-Purpose Flour, sifted
1 ½ cups (300g) Granulated Sugar
1 tbsp Baking Powder
½ tsp Salt
½ cup (113g) Unsalted Butter, softened to room temperature
1 cup (240ml) Whole Milk, room temperature
2 Large Eggs, room temperature
2 tsp Pure Vanilla Extract

Instructions for the Vanilla Cake Layers:

1. Preheat and Prepare: Preheat your oven to 350°F (175°C). Grease and flour two 8-inch (20cm) round cake pans, or line the bottoms with parchment paper circles and spray the sides. This prevents sticking and ensures easy release.

2. Whisk Dry Ingredients: In a large bowl, whisk together the sifted all-purpose flour, granulated sugar, baking powder, and salt. Make sure there are no lumps and the ingredients are evenly distributed.

3. Cream Butter: In a separate medium bowl, using an electric mixer (handheld or stand mixer with paddle attachment), beat the softened unsalted butter on medium speed until creamy and pale, about 2-3 minutes. This aerates the butter, creating tiny air pockets essential for a light cake.

4. Combine Wet Ingredients: In a small bowl, whisk together the whole milk, large eggs, and pure vanilla extract until just combined. Ensure these are at room temperature for optimal emulsification.

5. Combine Wet and Dry: Gradually add the dry ingredients to the butter mixture, alternating with the wet ingredients, beginning and ending with the dry. Start by adding about one-third of the dry ingredients, mix on low speed until just combined. Then add half of the wet ingredients, mix until just incorporated. Repeat with another third of the dry, the remaining wet, and finally the last third of the dry ingredients. Be careful not to overmix; overmixing develops gluten, leading to a tough cake.

6. Fill Pans and Bake: Divide the batter evenly between the two prepared cake pans. Smooth the tops with a spatula. Bake for 25-30 minutes, or until a wooden skewer or toothpick inserted into the center comes out clean. The cakes should be lightly golden and spring back when gently pressed.

7. Cool: Remove the cakes from the oven and let them cool in their pans on a wire rack for 10-15 minutes. This allows them to firm up slightly. After 15 minutes, carefully invert the cakes onto the wire rack to cool completely. Cooling completely is crucial before frosting, otherwise, the frosting will melt.

Ingredients for the Vanilla Buttercream Frosting:

1 cup (226g) Unsalted Butter, softened to room temperature
4 cups (480g) Powdered Sugar (Confectioners' Sugar), sifted
2-3 tbsp Whole Milk or Heavy Cream, room temperature
2 tsp Pure Vanilla Extract
Pinch of Salt (optional, but enhances flavor)

Instructions for the Vanilla Buttercream Frosting:

1. Cream Butter: In a large bowl, using an electric mixer with a paddle attachment, beat the softened unsalted butter on medium speed for 3-5 minutes until very light, fluffy, and pale in color. This is the secret to light, airy buttercream.

2. Add Powdered Sugar: Gradually add the sifted powdered sugar, one cup at a time, mixing on low speed until just combined after each addition. Once all sugar is added, increase speed to medium and beat until fully incorporated and smooth.

3. Add Liquid and Flavor: Pour in 2 tablespoons of milk or cream, vanilla extract, and the pinch of salt (if using). Beat on medium-high speed for another 2-3 minutes until the buttercream is light, fluffy, and smooth. If it's too thick, add the remaining tablespoon of milk or cream, one teaspoon at a time, until desired consistency is reached. If it becomes too thin, add a little more sifted powdered sugar.

Cake Assembly:

1. Level Cakes (Optional): If your cake layers have domed tops, use a serrated knife to carefully level them, creating flat surfaces for stacking.

2. Crumb Coat: Place one cake layer on your serving plate or cake stand. Spread a thin layer of buttercream over the top and sides of this layer. This "crumb coat" traps any loose crumbs, preventing them from mixing into your final frosting layer. Chill the cake in the refrigerator for 15-20 minutes until the crumb coat is firm.

3. Stack and Frost: Once the crumb coat is firm, place the second cake layer on top. Spread a generous amount of the remaining buttercream over the top and sides of the entire cake, smoothing it with an offset spatula or bench scraper for a neat finish. Get creative with swirls or textures!

4. Serve and Store: Your beautiful Classic Vanilla Layer Cake is ready to be enjoyed! Store any leftover cake covered at room temperature for up to 2 days, or in the refrigerator for up to 5 days. Bring to room temperature before serving for the best flavor and texture.

烘焙专家秘籍：确保蛋糕成功的关键点

要烘焙出完美无瑕的蛋糕，除了精准的配方，还需要掌握一些关键技巧。这些“专家秘籍”将帮助您规避常见的烘焙陷阱，让您的蛋糕更上一层楼。

1. 食材温度至关重要：确保黄油、鸡蛋和牛奶都达到室温。冷食材混合时会乳化不良，导致面糊分离，影响蛋糕的质地。室温的黄油更容易打发蓬松，而室温的鸡蛋和牛奶则能更好地与面糊融合，形成稳定且细腻的乳液。

2. 精准测量，尤其是面粉：烘焙是一门科学，精确的测量是成功的基石。对于面粉，请使用“勺入抹平法”（spoon and level method）：用勺子将面粉轻轻舀入量杯，然后用刀背或直尺将多余的面粉刮平。切勿直接用量杯舀面粉，这样会导致面粉被压实，实际用量过多，使蛋糕变得干硬。

3. 切勿过度搅拌：一旦加入面粉，搅拌就应轻柔且快速，直到刚刚混合均匀即可。过度搅拌会激活面粉中的面筋（gluten），导致蛋糕质地变得坚韧、有嚼劲，而非松软。面糊中保留一些小小的面粉块是完全正常的，它们会在烘烤过程中自然消失。

4. 烤箱温度与烘烤时间：强烈建议使用烤箱温度计校准您的烤箱。家用烤箱的实际温度常常与显示温度不符，这会严重影响烘焙效果。在烘烤过程中，尽量避免频繁打开烤箱门，尤其是前半段，因为冷空气的涌入会导致蛋糕塌陷。

5. 冷却的艺术：蛋糕出炉后，先在模具中冷却10-15分钟，让其结构稳定。然后倒扣在冷却架上完全冷却。如果蛋糕在未完全冷却的情况下脱模，可能会散架。同样，在蛋糕完全冷却之前就涂抹糖霜，糖霜会融化，导致蛋糕变得一团糟。

6. 糖霜的技巧：打发黄油时要足够充分，使其变得非常蓬松和苍白。这是奶油糖霜轻盈口感的关键。如果糖霜太稠，可以逐勺加入牛奶或奶油；如果太稀，则可逐勺加入过筛的糖粉。在涂抹第一层薄薄的“防掉屑层”（crumb coat）后，务必放入冰箱冷藏15-20分钟，让其凝固，这样能有效锁住蛋糕屑，使最终的糖霜涂层光滑整洁。

常见问题与故障排除

即使是经验丰富的烘焙师，也可能遇到问题。以下是一些常见问题及其解决方案：

蛋糕塌陷或中间下沉：

可能原因：烤箱温度过低，烘烤时间不足（未烤熟），面糊中膨胀剂（泡打粉）过多，或在烘烤过程中过早打开烤箱门。

解决方案：使用烤箱温度计校准温度；确保烘烤至插入牙签取出干净为止；精确测量膨胀剂；烘烤前半段不要打开烤箱门。

蛋糕质地干硬：

可能原因：面粉用量过多（测量不准确），烘烤时间过长或烤箱温度过高，面糊过度搅拌。

解决方案：采用“勺入抹平法”测量面粉；根据烤箱调整烘烤时间和温度；面粉加入后，仅搅拌至刚刚混合均匀。

面糊分层或看起来像凝乳：

可能原因：食材温度不一致，特别是黄油、鸡蛋和牛奶。冷食材难以与打发的黄油充分乳化。

解决方案：务必使用室温的黄油、鸡蛋和牛奶。如果面糊开始分层，可以稍微加热面糊（比如隔水加热几秒钟），同时快速搅拌，直到乳化。

蛋糕从模具中取出时散开：

可能原因：模具未充分涂油撒粉，或蛋糕在模具中冷却时间不足。

解决方案：确保模具充分准备（涂油撒粉或铺烘焙纸）；让蛋糕在模具中冷却至少10-15分钟后再倒扣。
