Gluten Free Chocolate Sheet Cake with Peppermint Icing

For a festive, sweet treat this holiday season- try this tender, moist, gluten free chocolate sheet cake, topped with a creamy peppermint icing. Then, sprinkled with crushed candy cane Hershey kisses for an extra sweet, peppermint treat!

Sheet cakes are terrific! They bake in just 15 minutes and can easily serve at least 20!

For a holiday version, I created a moist, chocolate sheet cake with a simple and sweet peppermint frosting. It’s a way to satisfy that sweet craving without committing to a large slice of a layered cake. Perfect to bring to a holiday gathering- May want to indulge in more than one. When sliced, this cake can be picked up or enjoyed with a fork.

Sheet cakes, particularly of the Texas variety, tend to have a thinner, glossy icing that is smoothed over the warm cake. I chose to allow the cake to cool and use a cream cheese-based peppermint frosting. Then, I sprinkled with chopped candy cane Hershey kisses. You could also use crushed candy canes.

What is a sheet cake?

Sheet cake is baked in a large, shallow pan, like a jelly roll pan. Regular cakes are typically baked in a 9x13 baking dish or round cake pans. Texas sheet cake is a chocolate sheet cake with a glossy ganache icing and topped with chopped pecans. 

Can I use a box mix to make a sheet cake?

Yes, if you’re short on time- a boxed cake mix can be used. In general, sheet cakes are known for being moist. You would also need to reduce the baking time from the box, as using a jellyroll pan will create a thinner cake.
