Gluten Free Lemon Sheet Cake

Bursting with citrus flavor, this gluten free lemon sheet cake makes the perfect spring dessert!

Spring time always has me craving lemon! On everything!

And lately, I have been very into sheet cakes. So, a lemon sheet cake seemed like a natural choice. Thin slices of moist cake, with a lemony-sweet icing. This cake is so moist- think très leche cake! The batter is infused with fresh lemon zest and lemon juice. I also added a bit of orange juice, but you can go all-lemon.

 Reasons to Love Sheet Cake

  • Bakes in just 15 minutes!
  • You can easily cut at least 20 slices!
  • A pourable icing that takes little time to prepare or spread!
  • Easy to decorate with a fun topping!- sprinkles, zest, nuts, candies, cookie crumbs, etc.
  • Always a crowd pleaser!

Lemon Sheet Cake Tips

        ◊ Use freshly squeezed lemon juice. Skip the stuff from the bottle. 

        ◊ Use fresh lemon zest. Always! Just do it.

        ◊ Pour glaze over the cake when it's still warm. Then, quickly spread before the glaze begins to set.

        ◊ Plan a fun topping- sprinkles, lemon zest, cookie crumbs, etc. Sometimes a few air bubbles will set into the icing.

        ◊ Store cake in the fridge.

        ◊ For best results- leave cake in the fridge overnight. Then, slice and enjoy the next day.

       ◊ Cut the cake with a plastic knife. This will keep your sheet pan from scratching, plus it will slice through the cake and icing a bit smoother.

What is the difference between sheet cake and regular cake?

The major difference involves the size of the cake pan. Sheet cakes use a large, shallow pan. Regular cakes are baked in a 9x13 baking dish or round cake pans.

 

What is a Texas sheet cake?

Some believe the name refers to the size of the cake. While people may use the term to describe a few different items, true Texas sheet cake very closely resembles German chocolate cake. There is a thin chocolate cake with a coconut-pecan frosting.

  • 2 Tbsp. maple syrup
  • 1 tsp. vanilla
  • 1/2 c. applesauce
  • 1/2 c. Greek lemon yogurt
  • Zest of 1 lemon
  • 3 Tbsp. lemon juice (about 1 1/2 lemons)
  • 1 Tbsp. orange juice
  • 1/4 c. milk
  • 2 eggs
  • 3/4 tsp. baking soda
  • 1 1/2 c. gluten free flour blend

Lemon Glaze

  • 4 Tbsp. butter

  • 1 - 2 Tbsp. lemon juice
  • 2 - 3 Tbsp. milk (total liquid between milk and lemon juice should be 4 Tbsp.)
  • 2 c. powdered sugar
Instructions
  1. Preheat oven to 350 degrees.
  2. In a large mixing bowl, whisk the butter, brown sugar, maple syrup, vanilla, applesauce, yogurt, lemon zest, lemon juice, orange juice, milk, and eggs. Next, whisk in the baking soda and flour. Pour batter into a greased jelly roll pan. Bake for 12-16 minutes, until an inserted toothpick comes out clean.
  3. In a small saucepan, heat the butter, coconut oil, lemon juice, milk, and powdered sugar over low heat. Whisk until a thick glaze forms. Pour over the warm cake and quickly smooth out with an offset spatula.
  4. Allow to cool before slicing- icing will set. Store leftovers in the fridge.
