A light, fluffy red velvet sheet cake with a subtle cocoa flavor and tangy cream cheese frosting. Baked in a simple 9×13-inch pan, this easy one-pan cake is perfect for sharing at holidays, parties, or anytime you want a classic dessert that feels a little special.
Preheat the oven to 350°F (175°C). Grease a 9x13-inch baking pan and line it with parchment paper if desired.
In a medium bowl, whisk together the flour, cocoa powder, baking soda, and salt. Set aside.
In a large mixing bowl, beat the eggs, sugar, and oil with an electric mixer on medium speed until well combined and slightly lightened, about 2 minutes.
Mix in the buttermilk and vanilla until smooth.
Reduce the mixer speed to low and add the flour mixture in two portions, mixing just until incorporated.
Stir in the vinegar and red food coloring until evenly distributed.
Pour the batter into the prepared pan and spread evenly. Bake 28 to 34 minutes, or until a toothpick inserted into the center comes out clean.
Cool completely in the pan on a wire rack.
To make the frosting:
Beat the cream cheese and butter together until smooth and creamy. Mix in the vanilla and salt.
Gradually add the confectioners’ sugar, about ½ cup at a time, beating until smooth and spreadable.
Spread the frosting evenly over the cooled cake. Slice and serve.

Notes
Cocoa powder: This recipe is written for natural cocoa powder, not Dutch-process. Using Dutch-process may affect the rise and flavor balance.
Color: Food coloring strength varies by brand. Start with the listed amount and add more if you prefer a deeper red.
Storage and make-ahead: The frosted cake can be made a day in advance and stored covered in the refrigerator up to 4 days. Let slices come to room temperature before serving for the best texture.
Freezing: Freeze the unfrosted cake, well-wrapped, for up to 2 months. Thaw overnight in the refrigerator before frosting.
