Lemon Sheet Cake


My poor Florida babies have been out west in the dry desert and can’t hang. Their lips are chapped. They’re faces are peeling and we can’t seem to get enough water to make the thirst go away. I guess we can’t ever move back here. 

It was so hot today I think I had heat stroke. The car temperature read 116 degrees. I think it was actually only (haha) 111 degrees but anything over 110 degrees just feels like a hot oven. 

Back in Florida my husband keeps the house so cold that sometimes I find reasons to turn the oven on so I can thaw out. Many of you may think I’m crazy for baking in mid-July but we still have to eat cake right?

Lemon Sheet Cake

Most of you aren’t strangers to sheet cakes but I’m guessing you’ve never had a lemon version? It’s fabulous especially topped with strawberries. 

It’s like the moist version of strawberry shortcake.


A sheet cake is a flat single layer rectangular cake baked in a jelly roll pan or sheet pan. It’s usually frosted and comes in all flavors.

  • I like this cake better the next day because the frosting makes the cake even more moist.
  • Make sure your pan is the right size. If you have a pan too big the cake will be super thin and dry.
