Hi Bold Bakers!

WHAT YOU GET: A simple vanilla sheet cake recipe, topped with fluffy vanilla buttercream, that will please everybody in the crowd.

No special occasion is required for this simple and delightful vanilla sheet cake with fluffy vanilla buttercream. I strongly believe a great Vanilla Cake should be in every baker’s repertoire, but sometimes you need a cake that will feed a larger audience than a three-layered circular cake.

This crowd-pleasing sheet cake has everything I love — a deliciously moist and tender crumb, the lovely taste of vanilla, and the most unbelievably fluffy buttercream icing. 

My homemade vanilla sheet cake recipe feeds 20 people easily, so feel free to invite a few extra folks around. Or, prepare for your next gathering and freeze this lovely cake until you’re ready to frost and serve!

Do I Need Cake Flour? 

Cake flour is essential for the tender, tight crumb of this cake, but don’t worry if you don’t have any on your shelf — you can easily make your own cake flour by following my recipe here.

What Type Of Frosting Should I Use On Sheet Cake?

This recipe calls for my Best-Ever Vanilla Buttercream, but feel free to explore other options that may fit your flavor preferences (and the weather) better. Try my Chocolate Buttercream or my Foolproof Strawberry Buttercream. If you’re worried about serving buttercream on a hot summer day, frost this cake with a stabilized whipped cream and top with fresh summer berries. Use my Stabilized Whipped Cream recipe!

Tools You Need To Make Vanilla Sheet Cake

  • Measuring cups and spoons
  • 13 x 18-inch (33 x 46-cm) half-sheet pan
  • Mixing bowls
  • Stand mixer or handheld electric mixer

Gemma’s Pro Chef Tips For Making Vanilla Sheet Cake

  • Make sure all of your ingredients are at room temperature before you start. This will ensure even mixing and will create a light and moist cake.
  • Cake flour is essential for the tender, tight crumb of this cake. If you don’t have any, you can easily make your own here. Cake flour weighs less than all-purpose flour: 1 cup is equal to 4 oz/115 g (compared to 1 cup of all-purpose flour, which is 5 oz/142 g).
  • Make sure your frosting is soft and at room temperature before using, or it will tear this delicate cake.
  • A crumb coat is helpful when frosting this cake: Spread a very thin layer of frosting over the entire surface of the cake to seal in the crumbs, then refrigerate the cake for 30 minutes to firm up. Proceed with frosting the cake.
  • You can turn this into a simple layer cake by cutting the cake into thirds and stacking the layers with frosting.
  • Use my Vanilla Buttercream. Or replace the vanilla buttercream with my Best-Ever Chocolate Buttercream,  Foolproof Strawberry Buttercream, or Salted Caramel Swiss Meringue Buttercream. On hot days, use my Stabilized Whipped Cream recipe and top with fresh fruit.

How best could I turn this into an orange cake – with orange flavoured water icing finish? A bit confused by the different liquids.
