Ingredients For Sheet Cake

Here you have your line up of ingredients. You are likely to have most of these things in your kitchen right now!

What is a Sheet Cake?

Sheet cakes are simple, one-layer, frosted cakes that are often prepared for celebrations that involve a dozen or more participants. This type of cake has become a popular option for birthday parties, celebrations in the workplace, and family reunions and anniversaries.

What Size Pan Do I Use For a Sheet Cake?

I prefer the half sheet size. A half-sheet cake is typically baked in a 12-inch-by-16-inch pan, but may also be made in a 11-inch-by-15-inch pan. A half sheet typically feeds 40 people. It can be sliced into 32 2-inch-by-3-inch slices or 48 2-inch-by-2-inch pieces.

Let’s get this party started ๐Ÿ™‚ย  Start with dumping all of the cake ingredients into the mixer. No particular order. I added the pudding mix next.

Add those eggs.

Oil, milk and sour cream.

Add a can of pumpkin.

How gorgeous is that?!

Transfer the sheet cake batter to the prepared baking sheet.

Spread the cake evenly to the edges.

Prepare The Cinnamon Roll Topping

Melt your butter, add the brown sugar and cinnamon ๐Ÿ™‚

Drizzle the cinnamon mixture over your sheet cake.


Run a knife through to swirl the goodness then bake 350 for 30-35 minutes.

Here’s a shot of how it looks right after baking, wait until you smell the aroma!

When the cake comes out of the oven, whip up the drizzle.

Drizzle while the cake is still warm….

….so it melts lovely like this ๐Ÿ™‚

The BEST Sheet Cake

Try serving warm with a small dollop of vanilla ice cream too.
