5 Layer Cake Recipe: Vanilla Buttercream Dreams in One Pan

This 5-layer cake recipe delivers showstopping elegance with a foolproof method that builds one perfect layer at a time. The secret lies in precise baking times and Swiss meringue buttercream that stays luscious at room temperature—no grainy texture here.

I've perfected this technique over years of baking competitions, where judges consistently praised the even layers and velvety frosting.

Each vanilla sponge layer bakes to a golden finish with just the right springiness, while the buttercream—infused with real vanilla bean—creates that signature professional look. The recipe includes step-by-step guidance for leveling, stacking, and creating clean edges that make even beginners look like cake artists.

No fancy equipment needed beyond a standard kitchen scale and offset spatula.

What you'll end up with is a restaurant-quality cake that's light yet sturdy enough to slice cleanly. The Swiss meringue technique eliminates the need for corn syrup, resulting in a frosting that's rich but never heavy.

Every bite delivers perfect balance between tender cake and velvety buttercream, with that signature vanilla aroma that makes it irresistible.

Perfect for celebrations, birthdays, or simply treating yourself, this cake builds confidence with its predictable results. The same method works for flavor variations like matcha or salted caramel—just swap the cake batter. Let's get baking!

Ingredients for 5 layer cake

Twelve ingredients transform into showstopping layers of velvety cake and dreamy buttercream—no secrets, just precision.

The flour and sugar are your foundation—King Arthur brand flour is my go-to for its protein balance, but Bob's Red Mill works beautifully too. Superfine sugar dissolves completely, preventing graininess in the batter. For the butter, Land O'Lakes or Plugrá are reliable choices, but any good-quality unsalted will do. The key is keeping it cold when creaming—draw it from the fridge just before use. Eggs should be room temperature to emulsify properly, so take them out 30 minutes ahead. Vanilla extract matters here—Madagascar bourbon vanilla adds depth, but Taster's Choice is a solid budget pick. Baking powder must be fresh; if it's over six months old, test it by mixing with water—it should foam immediately.

No vanilla bean? Double the extract, but you'll miss that signature aroma. Substituting cake flour? Use all-purpose minus 2 tbsp per cup, sifted. For a dairy-free version, swap milk for unsweetened almond milk and use vegan butter (though texture will differ). The gelatin in the buttercream can be replaced with agar-agar at half the amount for a vegan option, though it won't stabilize as perfectly. Powdered sugar should be sifted before adding to avoid lumps—Domino brand is my favorite for its fine grind. If you're short on time, pre-sifted powdered sugar from the baking aisle works, but I always sift mine for that ultra-smooth finish.

Store cake layers at room temperature in an airtight container for up to 3 days, separated by parchment. Buttercream keeps for 5 days refrigerated or 3 months frozen—thaw overnight in the fridge. For assembly, work in a cool room (65-70°F) to prevent melting. The cake freezes beautifully too: wrap each layer individually in plastic and freeze for up to 2 months. Thaw completely before assembling. Pro tip: Brush layers with simple syrup (equal parts sugar and water, heated) just before adding frosting for that signature moisture—trust me, it makes all the difference.

Step-by-step instructions for vanilla buttercream layer cake

This is how you build a showstopping 5-layer cake with perfect texture and flawless layers.

Preheat your oven to 350°F and grease five 6-inch round cake pans. Line the bottoms with parchment circles for easy removal. In a large bowl, whisk together the 4.5 cups all-purpose flour, 2.5 cups granulated sugar, 2 tbsp baking powder, and 0.5 tsp salt. Sift this mixture twice through a fine-mesh sieve to ensure no lumps remain.

In a separate bowl, beat the 2 cups unsalted butter and 12 whole large eggs on medium speed until the mixture is pale and fluffy, about 5 minutes. Gradually add the dry ingredients while mixing on low speed, alternating with the 1.5 cups whole milk. Scrape down the sides of the bowl as needed. Divide the batter evenly among the prepared pans.

Bake for 20-25 minutes or until a toothpick inserted in the center comes out clean. Let the cakes cool in the pans for 10 minutes before transferring to a wire rack to cool completely. This prevents them from cracking when removed. The layers should be light and tender with a slightly domed top.

In a heatproof bowl, combine the 3 cups heavy whipping cream and the seeds scraped from the 1 whole vanilla bean. Place the bowl over a saucepan of simmering water and heat to 160°F, whisking constantly until the mixture reaches the soft-ball stage. Remove from heat and immediately whisk in the 6 cups powdered sugar and 2 tbsp pure vanilla extract.

Beat the mixture with an electric mixer on high speed until it cools to room temperature and forms stiff peaks. This process, called Swiss meringue, creates a stable, smooth frosting that won't melt in warm temperatures. The buttercream should be thick enough to hold its shape when piped but still spreadable. If it's too soft, chill for 30 minutes to firm up.

Place the first cake layer on a cake stand or plate. Spread a thin layer of buttercream (about ¼ cup) over the top to create a "crumb coat." This prevents crumbs from getting into the final frosting. Repeat with the remaining four layers, stacking them with a thin buttercream layer between each.

For stability, place a small piece of parchment paper between each layer to catch any excess filling. Use a long serrated knife to level the top of each layer if needed. The final cake should be about 3-4 inches tall when complete. Chill the assembled cake in the refrigerator for 30 minutes to firm up the buttercream before final decorating.

Bloom the 1.5 tbsp unflavored gelatin in ¼ cup cold water for 5 minutes to soften. Heat the mixture in a small saucepan until the gelatin dissolves completely, then let it cool slightly. Gently fold this into the remaining buttercream to add stability and prevent the cake from collapsing.

Once the cake is chilled, spread the remaining buttercream over the entire surface, creating a smooth base. Use an offset spatula to create clean, straight sides. For extra stability, wrap the cake in plastic wrap and refrigerate for at least 4 hours or overnight. This ensures the layers stay perfectly aligned and the frosting holds its shape.

Remove the cake from the refrigerator and let it sit at room temperature for 10-15 minutes before decorating. Use a piping bag fitted with a star tip to pipe swirls or rosettes of buttercream on top. For a classic look, pipe a border around the edge and add fresh berries or edible flowers for color. The cake should be served at room temperature for the best texture and flavor.

Slice into 12 even portions using a long serrated knife that's been dipped in hot water and wiped dry. This creates clean cuts without smashing the layers. Each slice should reveal perfectly moist cake with smooth buttercream filling. Serve immediately for the most impressive presentation.

Troubleshooting this dish

Cracked Cake Layers

Cracks usually happen when layers cool too quickly or are removed from pans prematurely. Always let cakes cool in pans for 10 minutes before transferring to racks. If cracks appear, simply fill them with leftover buttercream before assembling—it creates a seamless finish.

I’ve seen this happen when oven temps fluctuate, so use an oven thermometer to confirm your 350°F setting is accurate. 🌟

Dense or Dry Layers

Overmixing the batter or using old baking powder are the top culprits. Mix just until combined—no need for a smooth batter. Test baking powder by mixing with water: it should foam immediately. For extra moisture, brush layers with simple syrup (equal parts sugar and water, heated) before adding frosting.
