How to Make the Perfect Red Velvet Sheet Cake

Red velvet cake is an iconic dessert with its striking red hue, tender crumb, and subtle cocoa flavor, topped with luscious cream cheese frosting. While it’s often baked as a layer cake, a red velvet sheet cake is equally impressive and much easier to make. This guide will walk you through the process of creating the ultimate red velvet sheet cake, complete with pro tips, fun variations, and answers to frequently asked questions.

A Brief History of Red Velvet Cake

Did you know that red velvet cake dates back to the early 1900s and gained popularity during the Great Depression? Some say its unique colour was initially the result of a chemical reaction between natural cocoa powder and acidic ingredients. Today, red velvet cake is beloved for its balance of flavor, velvety texture, and festive look.

Why Choose a Sheet Cake?

Sheet cakes are perfect for casual gatherings, bake sales, and even birthdays. They’re easy to assemble, transport, and serve—plus, there’s no need to fuss over stacking layers or crumb coats. Whether you’re baking for a crowd or just want a low-maintenance dessert, a sheet cake is the way to go.

Ingredients You’ll Need

For the Cake:

2 1/2 cups (310g) all-purpose flour
1 1/2 cups (300g) granulated sugar
1 tsp baking soda
1 tsp salt
1 tsp unsweetened cocoa powder
1 cup (240ml) buttermilk, at room temperature
1 1/2 cups (360ml) vegetable oil
2 large eggs, at room temperature
2 tbsp red food coloring (gel or liquid)
1 tsp pure vanilla extract
1 tsp white vinegar

For the Cream Cheese Frosting:

8 oz (227g) cream cheese, softened
1/2 cup (115g) unsalted butter, softened
4 cups (480g) powdered sugar
1 tsp vanilla extract

Step-by-Step Instructions

Step 1: Preheat the Oven and Prepare the Pan

Preheat your oven to 350°F (175°C).
Grease a 9×13-inch sheet pan with butter or non-stick spray, then line it with parchment paper for easy removal.

Step 2: Mix the Dry Ingredients

In a medium bowl, whisk together the flour, sugar, baking soda, salt, and cocoa powder.
Pro Tip: Sift the cocoa powder to ensure there are no lumps in the batter.

Step 3: Combine the Wet Ingredients

In a large mixing bowl, whisk together the buttermilk, vegetable oil, eggs, food coloring, vanilla extract, and vinegar.
Ensure the ingredients are fully combined for a smooth batter.

Step 4: Combine Wet and Dry Ingredients

Gradually add the dry ingredients to the wet mixture, stirring until just combined.
Pro Tip: Avoid overmixing to keep your cake light and fluffy.

Step 5: Pour and Bake

Pour the batter into the prepared sheet pan, smoothing it out with a spatula.
Bake for 30–35 minutes, or until a toothpick inserted into the center comes out clean.
Allow the cake to cool completely in the pan before frosting.

Step 6: Make the Cream Cheese Frosting

In a large bowl, beat the cream cheese and butter together until smooth and creamy.
Gradually add the powdered sugar, one cup at a time, beating well after each addition.
Stir in the vanilla extract.

Step 7: Frost the Cake

Spread the frosting evenly over the cooled cake using an offset spatula.
Garnish with cake crumbs, sprinkles, or fresh berries for an extra touch.

Tips and Tricks for Success

Room-Temperature Ingredients: Use room-temperature eggs and buttermilk for a smoother batter and even baking.
Use Gel Food Coloring: Gel food coloring gives a vibrant red hue without affecting the batter’s consistency.
Avoid Overbaking: Check for doneness at the 30-minute mark to prevent a dry cake.
Cool Before Frosting: Frosting a warm cake will cause the frosting to melt and slide off.
Make Ahead: Bake the cake a day in advance and store it unfrosted in an airtight container. Frost the cake on the day of serving.
Clean Cuts: Chill the frosted cake for 30 minutes before slicing to achieve clean edges.

Variations and Serving Suggestions

Flavor Twist: Add a teaspoon of orange zest to the batter for a citrusy twist.
Alternative Frosting: Swap cream cheese frosting for whipped mascarpone or a chocolate ganache.
Layered Sheet Cake: Cut the sheet cake in half and stack the layers with frosting in between for a semi-layered look.
Pairings: Serve with a scoop of vanilla ice cream or a glass of cold milk.
