Ingredients
- 3 cups (360g) all-purpose flour, spooned and leveled
- 2 1/2 teaspoons baking powder
- 1/2 teaspoon baking soda
- 1 teaspoon fine salt
- 1 cup (2 sticks/226g) unsalted butter, at room temperature
- 2 cups (400g) granulated sugar
- 4 large eggs, at room temperature
- 2 teaspoons pure vanilla extract
- 1 cup (240ml) whole milk, at room temperature
- 1/2 cup (120ml) sour cream, at room temperature
Instructions
- Preheat your oven to 350°F (175°C). Lightly grease an 11×15-inch sheet cake pan and line the bottom with parchment paper for easy removal.
- In a medium bowl, whisk together the flour, baking powder, baking soda, and salt. Set aside.
- In a large mixing bowl, beat the butter and sugar together on medium-high speed for 3-4 minutes, until light and fluffy. Scrape down the sides of the bowl as needed.
- Add the eggs one at a time, beating well after each addition. Mix in the vanilla extract.
- In a measuring cup or small bowl, whisk together the milk and sour cream until smooth.
- With the mixer on low, add the flour mixture in three additions, alternating with the milk-sour cream mixture (beginning and ending with the flour). Mix until just combined. Do not overmix.
- Pour the batter into the prepared pan and smooth the top with a spatula.
- Bake for 28-35 minutes, or until the center springs back when lightly touched and a toothpick inserted in the center comes out clean or with a few moist crumbs.
- Let the cake cool in the pan on a wire rack for 15-20 minutes. Run a thin knife around the edges, then carefully turn out onto a rack to cool completely before frosting.
Tips
- Ingredient Temperature: For a tender, even crumb, ensure all ingredients are at room temperature before mixing. This helps them blend smoothly and prevents lumps.
- Substitutions: If you don’t have sour cream, plain full-fat Greek yogurt works well as a substitute. For a dairy-free version, use a plant-based butter and milk substitute, but results may vary.
- Measuring Flour: Always spoon flour into your measuring cup and level it off with a knife. Scooping can pack too much flour, resulting in a dense cake.
- Don’t Overbake: Check your cake at 28 minutes. Overbaking dries out yellow cake quickly, so pull it as soon as a toothpick comes out clean or with a few moist crumbs.
Serving Suggestions
- Frosting: Classic chocolate buttercream, vanilla buttercream, or cream cheese frosting are all delicious. For a lighter touch, try a whipped cream topping and fresh berries.
- Occasions: This cake is perfect for birthdays, potlucks, family reunions, or any event where you need generous servings.
- Decorating: Dress it up with colorful sprinkles, edible flowers, or a drizzle of caramel or chocolate sauce for extra flair.
- Serving Size: An 11×15-inch cake typically yields 24–30 servings, depending on how large you cut the pieces.
Variations
- Lemon Yellow Sheet Cake: Add 2 tablespoons of lemon zest to the batter and swap half the vanilla for lemon extract for a bright, citrusy twist.
- Marble Sheet Cake: Swirl in 3/4 cup melted semisweet chocolate or chocolate batter into the yellow cake before baking for a marbled effect.
- Funfetti Sheet Cake: Fold in 1/2 cup of rainbow sprinkles into the finished batter for a fun, festive look kids love.
- Nuts or Chips: Stir in 1 cup of mini chocolate chips or toasted chopped pecans for added texture and flavor.
Storage and Reheating
- Room Temperature: Unfrosted cake can be wrapped tightly and stored at room temperature for up to 2 days. Once frosted (with buttercream), cover and store at room temperature for up to 1 day.
- Refrigeration: For longer storage, refrigerate the frosted cake, well covered, for up to 5 days. Bring to room temperature before serving for best texture and flavor.
- Freezing: The unfrosted cake can be wrapped in plastic and foil and frozen for up to 2 months. Thaw overnight in the refrigerator, then bring to room temperature before frosting and serving.
- Reheating: To refresh slices, microwave individual portions for 10-15 seconds. Avoid overheating, which can dry out the cake.
Frequently Asked Questions
- Can I use cake flour instead of all-purpose flour?
Cake flour will yield a slightly lighter, more tender crumb. Substitute 3 cups of cake flour for the all-purpose flour, but reduce the baking powder to 2 teaspoons. The cake may rise a bit less but will be extra soft. - Can I make this recipe in advance?
Yes, you can bake the cake up to two days ahead. Wrap it tightly in plastic wrap once completely cool. Frost the day you plan to serve for best freshness. - What’s the best way to frost a large sheet cake?
For smooth frosting, use an offset spatula or a large bench scraper. Start with a thin crumb coat, chill for 15 minutes, then apply a thicker final layer. For a decorative finish, use a piping bag with a large tip or simply swirl with your spatula. - How do I ensure the cake bakes evenly in a large pan?
Spread the batter evenly and tap the pan gently on the counter to release air bubbles. If your oven bakes unevenly, rotate the pan halfway through baking. Avoid opening the oven door too often, as this can cause the cake to sink. - Can I halve this recipe?
Yes, halve all the ingredients and bake in a 9×13-inch pan. The baking time will be slightly less, so check for doneness at 22–25 minutes. - Is this cake sturdy enough for stacking or layering?
This yellow sheet cake is sturdy enough for light layering (such as a two-layer cake) if you cut it in half, but for taller or more elaborate layer cakes, consider a denser recipe specifically designed for stacking.
