Ingredients for 13×18 sheet cake
Restaurant-quality layers start with these precise ingredients—each plays a key role in creating height and stability.
| Ingredient | Amount | Notes |
|---|---|---|
| All-Purpose Flour 🌾 | 4 ½ cups | Sifted for even texture |
| Granulated Sugar 🍚 | 2 ¼ cups | White or light brown preferred |
| Unsalted Butter 🧈 | 1 ½ cups | Room temperature, cubed |
| Large Eggs 🥚 | 6 whole | Room temperature for blending |
| Vanilla Extract 🌿 | 2 tsp | Pure, high-quality extract |
| Baking Powder 🍞 | 2 tsp | Diamond Crystal preferred |
| Salt 🧂 | ½ tsp | Fine sea salt preferred |
| Whole Milk 🥛 | 1 ½ cups | Room temperature for best results |
| Buttercream Frosting 🧁 | 4 cups | Homemade or high-quality store-bought |
| Powdered Sugar 🍚 | 2 cups | For buttercream preparation |
| Heavy Whipping Cream 🥛 | 1 ½ cups | Cold for buttercream stability |
| Food Coloring 🎨 | 1 tsp | Gel-based for vibrant color |
| Sprinkles 🌈 | 1 cup | Assorted colors for decoration |
| Parchment Paper 📄 | 1 sheet | For cake cutting and stacking |
The flour and sugar are the foundation of this cake’s structure. King Arthur or Bob’s Red Mill flour yields the best texture for clean layers, while Domino or C&H sugar ensures consistent sweetness. For butter, Plugrá or Land O’Lakes brands are ideal—they hold shape well when baked. Eggs should be large and room temperature to blend smoothly, avoiding lumps. The vanilla extract? Nielsen-Massey or McCormick pure extracts elevate the flavor without overpowering. Baking powder is critical here—Diamond Crystal has more lift than aluminum-based brands, which can make the cake too dense for clean cutting.
No buttercream on hand? Homemade buttercream with powdered sugar and heavy cream works perfectly—just whip the cold cream to stiff peaks before folding in softened butter. Short on milk? Evaporated milk or even water in a pinch, though whole milk yields the best crumb. The food coloring can be swapped for natural spirulina or beet powder for vibrant hues without artificial additives. Sprinkles are purely decorative, but Wilton or Sugarfina brands resist melting better under hot lights. For the cake cutting, a serrated knife dipped in hot water ensures clean slices every time—no jagged edges.
Store the baked cake layers wrapped in parchment at room temperature for 2 hours before frosting to prevent condensation. Once stacked, keep the cake in the fridge for up to 3 days if not serving immediately—just bring to room temp before slicing. The buttercream can be made 2 days ahead and stored in an airtight container. For large gatherings, assemble the cake on a wire rack over a baking sheet to catch any drips. The parchment paper between layers prevents sticking, making reassembly a breeze if you need to transport it.

Step-by-step instructions for building a 13×18 sheet cake with layered height
This method transforms a single sheet cake into three elegant layers without compromising structure.
Prepare the Cake Batter for Even Baking
Preheat your oven to 350°F and line a 13×18-inch jelly roll pan with the parchment paper. Sift together the 4.5 cups all-purpose flour, 2 tsp baking powder, and 0.5 tsp salt in a large bowl to eliminate lumps. This ensures a light, airy texture throughout each layer.
In a separate bowl, cream the 1.5 cups unsalted butter and 2.25 cups granulated sugar on medium speed until light and fluffy—about 3-4 minutes. This step incorporates air, which is critical for achieving the height we need in each layer. Add the 6 whole large eggs, one at a time, mixing well after each addition. The mixture should nearly double in volume and become pale in color.
Alternate adding the 1.5 cups whole milk and the sifted dry ingredients, beginning and ending with the milk. Mix on low speed just until combined—overmixing develops gluten, which can make the cake dense. Stir in the 2 tsp vanilla extract until evenly distributed. The batter should be smooth and slightly thick, with no visible flour streaks.
Bake the Cake for Perfect Flatness and Structure
Pour the batter evenly into the prepared pan, spreading it into the corners to ensure even thickness. Bake for 25-30 minutes, or until a toothpick inserted in the center comes out clean. The cake should be golden brown and spring back gently when pressed. Rotate the pan halfway through baking for even heat distribution.
Immediately after removing from the oven, invert the cake onto a clean kitchen towel dusted with powdered sugar. This prevents sticking and helps create a smooth surface for rolling. Let the cake cool completely on the towel for 1 hour before proceeding. This cooling step is crucial—it allows the cake to set properly, making it easier to roll and layer without cracking.
Roll and Frost the First Layer
Once the cake is completely cool, carefully peel away the parchment paper. Place the towel with the cake on a clean work surface and gently roll the cake from the long side, using the towel to help guide it. The cake should roll up tightly, revealing a smooth, flat surface.
Remove the towel and place the rolled cake on a wire rack. Spread 1 cup of the buttercream frosting evenly over the exposed surface, leaving a ½-inch border unfrosted. This thin layer of frosting will act as a glue for the second layer. Sprinkle ¼ cup of the sprinkles evenly over the frosted surface and gently press them in. Let the frosting set for 5 minutes before proceeding.
Stack and Frost the Final Layers
Unroll the cake carefully and place it back on the wire rack. Repeat the rolling process, this time frosting the newly exposed surface with another 1 cup of buttercream frosting. Again, leave a ½-inch border unfrosted and sprinkle another ¼ cup of sprinkles. Let the frosting set for 5 minutes before rolling again.
For the final layer, unroll the cake one last time and place it on a serving board or cake stand. Frost the top and sides completely with the remaining 2 cups of buttercream frosting, using an offset spatula to create smooth, even strokes. Press the remaining ½ cup of sprinkles onto the sides and top while the frosting is still soft. Chill the cake in the refrigerator for 30 minutes before slicing to allow the frosting to firm up.
Cut and Serve with Precision
Use a long, sharp serrated knife to cut the cake into 12 equal rectangles (about 4×6 inches each). Dip the knife in hot water, wipe it clean, and make each cut with a gentle sawing motion. This ensures clean, professional-looking slices. Serve immediately for the best texture—each slice should have a tender crumb, smooth frosting, and vibrant sprinkles.
The key to success here is patience—allowing each layer to cool and set properly prevents cracking and ensures the cake holds its shape when stacked. The result is a show-stopping sheet cake that delivers restaurant-quality presentation with minimal effort.
Pro Tips For Making 13×18 Sheet Cake
- MEASURE BUTTER COLD: Take the butter straight from the fridge—no thawing, no softening. Cut it into tablespoons first, then rub it into the flour with your fingertips until it’s pea-sized. I learned this the hard way after mixing butter that was too soft and ending up with a greasy, dense mess. Cold butter creates flaky layers that actually make the cake tender, not tough.
- WHISK EGGS ROOM TEMP: Let your eggs sit in warm water for 5 minutes before cracking them—no need to fully cook them, just take the chill off. Room-temperature eggs blend smoother and emulsify better with the butter, which means fewer lumps and a lighter texture. I used to skip this and wondered why my cakes sometimes turned out gummy.
- STOP WHEN SPRINGY: Test for doneness by pressing the center—it should bounce back slowly, not jiggle like jelly. Overbaking dries out the cake, especially in a 13×18 pan where heat spreads unevenly. If you’re unsure, check at 20 minutes and cover loosely with foil if it’s browning too fast.
- SIFT FLOUR TWICE: Sift the flour into the bowl before mixing, then give it one more sift halfway through combining. This removes clumps and aerates the flour, which keeps the cake light. I was skeptical until I tried it—now my cakes rise higher and have that professional look. (Yes, it’s extra work, but it’s worth it.)
Regional styles of 13×18 sheet cake
Southern Classic Style
In the South, this sheet cake often transforms into a hummingbird cake by folding in 1 cup chopped pecans and 1 cup diced pineapple into the batter. Use cream cheese frosting instead of buttercream for a tangy twist, and top with toasted pecan halves and maraschino cherries.
For extra Southern flair, dust the top with powdered sugar and add miniature American flags as decorations. 🌟
New York City Bakery Approach
New York bakeries elevate this cake with vanilla bean paste (replace the extract) and a salted caramel drizzle on top. Use dark brown sugar for deeper flavor and add 1 tsp cinnamon to the batter.
For presentation, cut into rectangular slices and serve on a marble slab with gold leaf accents. The key here is precision—bakeries often use weight measurements (grams) for consistency. ✨
Midwest Homestyle Twist
The Midwest loves this cake with chocolate swirls—mix ½ cup cocoa powder into ½ cup of the batter before pouring, then swirl it in with a knife. Frost with cream cheese frosting and decorate with homemade maple glaze (mix 1 cup powdered sugar with 2 tbsp maple syrup).
Add chopped walnuts for crunch and serve with vanilla ice cream on the side. 💛
West Coast Fusion
West Coast bakers often infuse the batter with 1 tsp orange zest and 1 tbsp coconut milk for a tropical vibe. Use matcha buttercream (add 1 tsp matcha powder to the frosting) and top with edible flowers and crushed macadamia nuts.
For a modern touch, cut into geometric shapes with a cake wheel instead of rectangles. This style thrives on bold flavors and artistic presentation. 🌸
Texas BBQ Cake
Yes, Texas has its own take! Replace vanilla extract with 1 tsp smoked paprika and add ½ cup BBQ sauce to the frosting. Top with crumbled bacon and pickled red onions for a sweet-savory combo.
Serve with whipped cream and a drizzle of honey for balance. This version is perfect for tailgates or backyard cookouts. 🔥

Frequently asked questions
Why does this recipe use a jelly roll pan instead of a half-sheet pan?
The 13×18-inch jelly roll pan creates a thinner, more even cake that rolls perfectly for layering. A standard half-sheet pan (18×24 inches) would be too large and make the cake too thick to roll cleanly. The jelly roll pan ensures the cake bakes evenly and stays flexible enough for rolling without cracking.
Can I make this cake in a smaller pan and still create layers?
Yes! Use a 9×13-inch pan instead, but reduce the batter by 25% (about 3.4 cups) for a single layer. Bake at 350°F for 20-25 minutes, then roll and frost as directed. For layers, cut the cooled cake into 3 equal strips (like a log) and stack them vertically with frosting. The technique works the same—just scale the dimensions!
What if my cake cracks when rolling?
Cracking usually happens if the cake cools too quickly or isn’t fully set. Let it cool 1-2 hours on the towel before rolling, and ensure it’s completely room temperature (not warm). If cracks appear, brush them with simple syrup (equal parts sugar and water, heated) to soften, then re-roll gently. For extra stability, chill the rolled cake in the fridge for 10 minutes before frosting.
How do I adjust this recipe for gluten-free baking?
Replace the 4.5 cups all-purpose flour with a 1:1 gluten-free flour blend (like Bob’s Red Mill or King Arthur) plus 1 tsp xanthan gum to bind. Reduce the milk to 1 cup (gluten-free batters absorb more liquid) and add 1 extra egg for structure. Bake at 325°F (lower temp prevents burning) for 30-35 minutes. Let cool 2 hours before rolling—gluten-free cakes are more fragile!
Can I make this cake ahead of time?
Bake the cake 1 day ahead and store it wrapped in plastic at room temperature. Assemble the layers 4-6 hours before serving—this lets the frosting set properly. For long-term storage, freeze the unfrosted rolled layers (wrapped tightly) for up to 1 month. Thaw overnight in the fridge before assembling. The flavors actually improve with time!
