UNSALTED BUTTER: Butter contributes fat for tenderness and flavor while also assisting in aeration when creamed with sugar. In cake batter, its semisolid nature allows it to trap air, which expands during baking, contributing to a lighter texture. In buttercream, its emulsifying properties create a smooth and stable frosting.
GRANULATED SUGAR: Sugar is more than just sweetness—it impacts structure and texture. It binds water molecules, reducing gluten formation for a more tender crumb. It also assists in aeration during creaming, helping to incorporate air pockets that contribute to the cake’s rise.
NEUTRAL OIL: Oil provides moisture and prevents the cake from feeling dry. Unlike butter, oil remains liquid at room temperature, lending a softer texture and prolonging the cake’s freshness.
EGG WHITES: Egg whites provide structure due to their protein content, which coagulates when heated, giving the cake stability. Without egg yolks, the cake has a finer, tighter crumb and a lighter texture. Since yolks contain fat, removing them slightly reduces richness, but the inclusion of sour cream and oil counterbalances this effect. The absence of egg yolks also helps keep the cake white, as the yolks’ yellow pigment would otherwise contribute to a more off-white color.
VANILLA EXTRACT: Vanilla enhances flavor complexity, adding warmth and aromatic depth to the cake. It also has alcohol, which can help distribute flavors more effectively throughout the batter.
ALL-PURPOSE FLOUR: Flour provides the primary structure of the cake through gluten development. The balance between flour, fat, and sugar determines the final texture—too much flour leads to toughness, while too little results in collapse.
BAKING POWDER: A chemical leavening agent, baking powder releases carbon dioxide gas when mixed with liquid and exposed to heat. This expands the air pockets created during creaming, causing the cake to rise. If double-acting, it releases gas both when mixed and when baked, ensuring an even rise.
KOSHER SALT: Salt enhances flavor by balancing sweetness and intensifying other taste perceptions. It also strengthens the gluten network slightly, improving texture.
WHOLE MILK: The balance of water, fat, and proteins influences structure and tenderness. Water hydrates the flour, allowing gluten to form, while milk proteins contribute to a fine crumb. The fat content helps create a softer texture, and
the natural sugars promote gentle caramelization for a golden crust. Room temperature is key—it blends more seamlessly into the batter, preventing curdling and ensuring even distribution of fat.
SOUR CREAM: The acidity from sour cream weakens gluten development, leading to a more delicate, tender cake. Second, it reacts with baking powder to create carbon dioxide, giving the batter an extra lift. The fat content contributes richness, and the tang subtly balances the cake’s sweetness.
CONFECTIONERS’ SUGAR: Unlike granulated sugar, which has large, sharp crystals, confectioners’ sugar is ground into a fine powder, often mixed with a small amount of cornstarch (around 3%) to prevent clumping. This ultra-fine texture means it dissolves effortlessly into buttercream, creating that silky-smooth finish. In frostings, it stabilizes fat and air, making sure everything holds its shape. The cornstarch also absorbs excess moisture, keeping buttercream from weeping or becoming grainy over time.
HEAVY WHIPPING CREAM: Heavy whipping cream is mostly butterfat (at least 36%), which means it brings luxurious richness to buttercream and an airy, cloudlike lightness to the strawberry filling. When whipped, the fat traps air, creating a structure that’s both stable and melt-in-your-mouth soft.
PURPLE LIQUID FOOD COLORING: Butter has a natural yellow hue thanks to beta-carotene in the milk fat. When you want a pristine white frosting, a tiny drop of purple food coloring neutralizes that yellow tint. This works because yellow and purple sit opposite each other on the color wheel—together, they create a neutral white instead of a warm, buttery yellow. The key? A microscopic amount. Too much, and suddenly your wedding cake frosting has a lilac undertone.
WATER: In the Vanilla Simple Syrup, water acts as a universal solvent, dissolving sugar to create a liquid that seeps into the cake layers, keeping them moist without making them soggy. It also plays a role in caramelization—when sugar and water heat up together, the water slows the browning process, allowing for even cooking. In the cake batter, the water content in milk and eggs controls gluten formation and starch gelatinization, both essential for structure.
FRESH STRAWBERRIES: Strawberries are around 90% water, which makes them a tricky ingredient in fillings—too much liquid and you risk a runny consistency. Roasting them solves this, evaporating excess water while concentrating natural sugars and deepening their flavor. Strawberries are also naturally acidic, which enhances the overall balance of the cake. The softening of pectin during roasting gives the filling a luscious texture, and the fruit’s bright tartness cuts through the richness of butter and cream.
CREAM CHEESE: Unlike butter, which is nearly pure fat, cream cheese contains about 55% water. This high moisture content gives frostings and fillings a smooth, spreadable consistency while also offering structure and stability. The acidity plays well with sugar, keeping the filling from becoming too sweet, and the tanginess enhances the flavor of the strawberries.
THE COMPONENTS
VANILLA WHITE CAKE: The foundation of this cake is a light and fluffy yet sturdy vanilla white cake. The recipe is flexible and can be scaled to create three distinct tiers—6-, 9-, and 12-inch cakes—plus a 13×9-inch sheet cake for extra servings, which makes it an ideal choice for both grand wedding cakes and more intimate gatherings.
VANILLA SIMPLE SYRUP: Soaking the cake layers in simple syrup is the secret to keeping the cake moist and flavorful. Infused with vanilla, the syrup elevates the subtle flavor of the cake and adds a gentle sweetness without overwhelming the palate.
STRAWBERRY CREAM FILLING: Fresh strawberries are roasted to intensify their flavor and then blended with a fluffy mixture of cream cheese and heavy whipping cream. The filling is light yet luxurious, offering the perfect balance to the vanilla cake and buttercream.
VANILLA AMERICAN BUTTERCREAM: This smooth, creamy buttercream is the perfect foil to the strawberries. Its buttery richness provides a lush texture that melts in your mouth. The addition of heavy cream gives the buttercream a soft, velvety consistency, making it easy to work with and perfect for creating smooth layers and beautiful decorations.
KITCHEN CONFIDANTS
Here are a few kitchen essentials that will help you create a cake worthy of any celebration. 
ROUND PANS: Round pans—typically 6-inch, 9-inch, and 12-inch—are the perfect trio for creating a classic tiered cake. These sizes allow you to build height and dimension, ensuring each layer is beautifully proportioned. With them, you can achieve a striking visual balance while serving differing numbers of guests. (Pictured: Williams Sonoma Goldtouch® Pro Nonstick Round Cake Pan in 6-inch, Williams Sonoma Goldtouch® Pro Nonstick Round Cake Pan in 9-inch, Fat Daddio’s Anodized Aluminum Round Cake Pan in 12×3-inch.)
RECTANGULAR BAKING PAN: A rectangular baking pan is essential for baking sheet cakes, which are perfect for serving larger crowds and can be decorated with the same elegance as tiered cakes. (Pictured: Williams Sonoma Goldtouch® Pro Nonstick Rectangular Cake Pan.)
SERRATED KNIFE: A serrated knife is your best friend when it comes to leveling cakes. Unlike a straight-edged knife, the serrated blade will help you cut through the sponge without disturbing the delicate crumb. Use it to trim off the tops of your layers so they sit evenly, ensuring each tier is perfectly level and ready for frosting. (Pictured: Zwilling Pro Bread Knife with Z15 Serration, 9 ”.)
CAKE BOARD: Each tier of the cake should be placed on its own cake board to ensure both structure and stability. Use appropriately sized greaseproof or plastic boards to match the dimensions of your tiers. If you choose greaseproof boards, tape two together with the greaseproof sides facing out to prevent moisture from the cake from weakening the board’s structure. These boards are essential for easy handling and transferring of layers and to keep the assembled cake stable and prevent it from shifting or collapsing as you stack and decorate.
CAKE TURNTABLE: A cake turntable is key for smooth, even piping and frosting. As you work with your buttercream, a turntable allows you to rotate the cake effortlessly, ensuring a flawless finish all the way around. This tool is a must for getting crisp, clean edges on your tiers and makes decorating a lot easier by giving you full 360-degree access.
WOODEN DOWELS: Wooden dowels provide support to your stacked tiers and keep them from falling over. Once you’ve assembled each tier, insert these dowels into each except for the topmost tier. The 12-inch wooden dowels are long enough to give your cake the strength it needs, and they can be cut to size to perfectly fit each tier using a PVC pipe cutter.
CAKE LIFTER: A cake lifter is particularly helpful when working with larger or tiered cakes, allowing you to lift and transfer your creations without worrying about damaging them. A sturdy cake mover will help you slide the cake off the turntable and onto your final cake plate or display stand with ease. (Pictured: Nordic Ware Cake Lifter.)
SQUEEZE BOTTLE: With a squeeze bottle, you can drizzle a thin, consistent layer of Vanilla Simple Syrup onto the cake layers, allowing them to absorb the liquid without oversaturating any areas. It’s far more precise than using a spoon or pouring directly, giving you the freedom to work in small, controlled amounts. This ensures the cake stays moist—not wet—with just the right balance of flavor and texture. (Pictured: OXO Good Grips Chef’s Squeeze Bottle-Medium.)
OFFSET SPATULAS: A large offset spatula is your go-to for spreading buttercream onto your cake. The long, offset blade allows you to glide on the surface with control, ensuring an even and smooth layer of frosting. A small offset spatula is ideal for adding fine details to your cake, especially around the edges, or for working in tight spaces between tiers. (Williams Sonoma Olivewood Offset Icing Spatula.)
LEVEL: Using a level when making a wedding cake is essential for ensuring each tier sits perfectly straight. It’s a small but crucial step that guarantees your tiers align beautifully and your cake stays steady, no matter how many layers it has. (9 Inch Level.)
SPRAY BOTTLE: Lightly misting the cake with water from a spray bottle before a finishing pass with a small offset spatula or bench scraper helps to even out the consistency of the buttercream and create a smooth, polished exterior. (Glass Spray Bottle.)
ARC RULER: An arc ruler helps you pipe symmetrical curves and delicate borders with ease. It’s especially useful for wedding cakes, where uniformity and elegance are essential, allowing each design element to flow seamlessly across the tiers. (Pictured: Fondant Cake Arc Ruler.)
PASTRY BAG/PIPING COUPLER: A sturdy pastry bag is indispensable for all your piping work. The flexible material allows you to squeeze with ease and precision, and it can be fitted with different piping tips to create a range of beautiful designs. And switching between tips is easy with the help of a piping coupler, which allows you to change designs without needing to swap out your bag.
GLASS NESTING BOWLS: Glass is nonreactive, meaning it won’t interfere with the chemical composition of ingredients like eggs, dairy, or acidic components. The transparency of glass also allows for easy monitoring of mixtures. Nesting bowls help with mise en place, ensuring all ingredients are measured and ready, which is crucial in precise baking. (Pictured: Glass Mixing Bowl 10-Piece Set.)
RIMMED BAKING SHEET WITH WIRE RACK: The rimmed baking sheet prevents spills when roasting strawberries, and the wire rack ensures even air circulation for cooling cakes. Heat transfer is optimized, preventing sogginess and allowing excess moisture to escape, which is critical for maintaining a cake’s structure. (Pictured: Williams Sonoma Goldtouch® Pro Nonstick Non Corrugated Half Sheet with Cooling Rack.)
SILICONE SPATULAS: Silicone is heat-resistant and flexible, making it ideal for scraping bowls efficiently, ensuring no ingredient is wasted. (Pictured: Get It Right Ultimate Spatula in Mint, Get It Right Mini Spatula in Mint.)
KITCHEN SHEARS: High-quality shears allow precise trimming of parchment paper for lining pans and of pastry bags, ensuring clean, controlled cuts. (Pictured: Zwilling Multi-Purpose Kitchen Shears.)
PVC PIPE CUTTER: A must-have for precise, clean cuts on wooden dowels used to support tiered cakes, this tool ensures stability by allowing you to trim dowels to the exact height needed, preventing uneven stacking and structural issues. (PVC Cutter.)
SAUCEPAN: A saucepan provides controlled heat distribution for making Vanilla Simple Syrup. The gradual heating process ensures even sugar dissolution, preventing crystallization and allowing the syrup to penetrate cake layers effectively for added moisture.
