Cream Cheese Sheet Cake with Chocolate Icing

Please share this post with your friends 🤗

This is a straightforward, comforting sheet cake that balances tender cake crumb with a glossy chocolate icing. The cake itself is rich thanks to butter and cream cheese folded into a batter sweetened with granulated sugar. It bakes in a single 15×10-inch pan, which makes it ideal for gatherings, potlucks, or a no-fuss dessert for the week.

The chocolate icing is a quick stovetop finish: evaporated milk, sugar, butter and chocolate chips come together in minutes to form a shiny, slightly fudgy glaze that sets over the cooled cake. I like to add sprinkles for a cheerful touch, but the icing is beautiful on its own.

Below you’ll find a concise ingredient list with purpose notes, a clarified step-by-step method that follows the provided directions exactly, troubleshooting tips, and storage guidance so this cake travels and keeps well.

Ingredient List

• 1 cup plus 2 tablespoons salted butter, softened — provides fat and structure; room temperature helps it cream smoothly with cream cheese.
• 6 ounces cream cheese, softened — adds moisture and a slight tang for a tender, rich crumb.
• 2 1/4 cups granulated sugar — primary sweetener for the cake batter; creamed with butter and cream cheese for aeration.
• 6 large eggs, room temperature — binders and leavening support; add one at a time for even incorporation.
• 1 teaspoon vanilla extract — flavor enhancer; adds warm, familiar aroma.
• 2 1/4 cups cake flour — lower-protein flour keeps the cake tender and soft.
• 1 cup granulated sugar — used in the icing mixture (distinct from the batter sugar).
• 1/3 cup evaporated milk — gives the icing body and a creamy mouthfeel when cooked with sugar.
• 1/2 cup salted butter, cubed — added to the hot icing to enrich and shine the glaze.
• 1/2 cup semi-sweet chocolate chips — melts into the hot mixture to form the chocolate component of the icing.
• sprinkles — optional garnish for color and fun; add after icing is poured but before it sets.

Build Cream Cheese Sheet Cake with Chocolate Icing Step by Step

• Preheat the oven to 325°F (about 163°C). Spray a 15x10x1-inch sheet pan with baking spray and set aside.
• In the bowl of an electric mixer fitted with the paddle attachment, combine 1 cup plus 2 tablespoons softened salted butter, 6 ounces softened cream cheese, and 2 1/4 cups granulated sugar. Beat on medium speed until the mixture is light in color and fluffy, about 3–5 minutes, scraping down the bowl once or twice.
• Add the 6 large eggs one at a time, beating briefly after each addition and scraping down the sides of the bowl to ensure even mixing. This keeps the batter smooth and prevents streaks of unmixed egg or fat.
• Beat in 1 teaspoon vanilla extract until incorporated.
• With the mixer on low speed, add 2 1/4 cups cake flour and beat just until blended. Stop as soon as the flour is incorporated to avoid overworking the batter; you want a uniform, slightly thick batter.
• Pour the batter into the prepared 15x10x1-inch sheet pan. Use an offset spatula or the back of a spoon to spread it evenly into the corners and smooth the top for uniform baking.
• Bake in the preheated 325°F oven for 30 to 35 minutes. The cake is done when the top is set and a toothpick inserted in the center comes out with a few moist crumbs but not wet batter. Ovens vary—check at 30 minutes and add time if needed.
• Remove the pan from the oven and allow the cake to cool completely in the pan on a wire rack before adding the icing. Cooling fully prevents the icing from sliding off and helps it set properly.
• To make the chocolate icing: in a medium saucepan, stir together 1 cup granulated sugar and 1/3 cup evaporated milk. Place over medium heat and bring to a boil, stirring occasionally so the sugar dissolves evenly.
• Once it reaches a boil, cover the saucepan and reduce the heat slightly so the mixture simmers gently without boiling over. Let it simmer, covered, for 2 minutes—this briefly cooks the sugar and evaporated milk into a cohesive base.
• Remove the saucepan from the heat. Immediately add 1/2 cup cubed salted butter and 1/2 cup semi-sweet chocolate chips. Stir until the butter and chocolate chips are fully melted and the icing is smooth.
• Let the icing cool very slightly for just a minute or two so it’s pourable but not piping-hot; this helps it spread but still set. Pour the icing evenly over the cooled cake, working from the center outward, and use an offset spatula to nudge it toward the edges if needed.
• If you like sprinkles, scatter them across the icing while it is still wet so they adhere. Allow the icing to set before slicing—about 20–30 minutes at room temperature.

Why This Recipe Belongs in Your Rotation

This sheet cake is dependable and scales well for a crowd. It’s not fussy: one pan, a straightforward butter-and-cream-cheese batter, and a quick stovetop chocolate glaze. The cake is tender and enriched without being overly dense, and the icing brings a fudgy shine that’s both visually appealing and satisfying in texture.

Because it uses common pantry ingredients and bakes in a shallow sheet pan, it’s great for last-minute plans. It also travels well—make it the night before, keep it covered, and bring it to a potluck or family gathering without losing much quality.

Ingredient Flex Options

• Butter: if you must, use unsalted butter and add 1/4 teaspoon salt to the batter to balance flavors.
• Cream cheese: full-fat yields the best texture; lower-fat versions may make the cake slightly less tender.
• Sugar: do not reduce quantities without testing—this balance affects structure and icing consistency.
• Chocolate chips: swap semi-sweet for dark chocolate chips for a less sweet glaze, or milk chocolate for a sweeter finish.
• Sprinkles: omit or replace with chopped nuts (wait until icing is set slightly so they stick) for crunch.

What You’ll Need (Gear)

• 15x10x1-inch sheet pan, sprayed with baking spray
• Electric mixer (stand or hand) with paddle attachment
• Medium saucepan for icing
• Offset spatula or rubber spatula to spread batter and icing
• Wire rack to cool the cake
• Measuring cups and spoons

Problems & Prevention

• Dense cake: ensure butter and cream cheese are fully softened so they cream properly with the sugar. Avoid overmixing after adding flour.
• Cake sinks in the center: check oven temperature with a thermometer—too hot or too cool can cause uneven rise and collapse. Also, don’t open the oven during the first 20–25 minutes of baking.
• Icing too runny: let the hot icing cool a minute or two before pouring; if it’s still too thin, chill briefly in the fridge, stirring occasionally, until it thickens slightly before pouring.
• Icing hardens too quickly: work swiftly when pouring and spreading. If it begins to set while you’re working, warm the pan briefly over low heat or microwave small portions to re-liquefy and then pour.

Seasonal Spins

• Spring/Easter: use pastel sprinkles and add a few drops of almond extract (replace a portion of the vanilla) for a seasonal twist.
• Fall: add 1/2 teaspoon ground cinnamon to the batter or top the icing with chopped toasted pecans instead of sprinkles.
• Winter/Holidays: fold 1/3 cup finely chopped dried cranberries into the batter after mixing the flour for a tart counterpoint, or use peppermint sprinkles on the icing.

Recipe Notes & Chef’s Commentary

Measure the cake flour by spooning it into the cup and leveling with a knife—don’t pack it. Cake flour is key to the tender texture; if unavailable, use 2 1/4 cups all-purpose minus 3 tablespoons, then add 3 tablespoons cornstarch (sift together), but the original calls for cake flour.

Room-temperature eggs and dairy combine more easily and trap air during creaming. Take the time to cool the cake completely before pouring the icing; a warm cake can cause the icing to run off and set thinly at the edges.

Meal Prep & Storage Notes

• Storage at room temperature: cover the cake loosely with foil or a cake dome and keep for 1–2 days.
• Refrigeration: store covered for up to 5 days. Bring to room temperature before serving for best texture and flavor.
• Freezing: you can freeze uniced slices wrapped tightly in plastic wrap and foil for up to 2 months. Thaw in the fridge overnight, then bring to room temperature before adding fresh icing if desired.
• Make-ahead: bake the cake a day ahead and keep it wrapped. Make the icing the day you serve for the freshest gloss, or prepare the icing and warm it gently before pouring if chilled.

Cream Cheese Sheet Cake with Chocolate Icing Q&A

• Q: Can I use regular milk instead of evaporated milk in the icing? — A: Evaporated milk gives a thicker, creamier base when cooked with sugar. Using regular milk will make the icing thinner and may change set time; if you must substitute, use about 1/4 cup less and watch consistency closely.
• Q: My icing separated—what went wrong? — A: If the chocolate and butter are added to very hot liquid, or if the heat is too high while simmering, the fats can separate. Remove from heat before adding chocolate and butter, and stir until smooth. Cooling slightly before adding can help.
• Q: Can I cut this into squares for serving? — A: Yes. After the icing sets, slice into squares with a sharp knife. For cleaner cuts, chill slightly and wipe the knife between slices.
• Q: Is the recipe scalable? — A: This specific method and pan size are designed for a 15x10x1-inch sheet. To scale up/down, adjust bake times and pan sizes accordingly and test for doneness early.
