Gingerbread Sheet Cake

Serve up this delicious molasses-rich gingerbread sheet cake for your next holiday party. It is 100% homemade, easy and serves a crowd.

There’s one flavor that my family craves as soon as cold weather hits. Gingerbread. We’ve made gingerbread houses with friends for the past 15 years and it’s the main way we indulge our gingerbread craving.

Lately we’ve turned to making this Gingerbread Sheet Cake. It’s a rich molasses cake that is soft and tender. And the molasses cream cheese frosting on top will melt in your mouth.

About this Gingerbread Sheet Cake:

  • Flavor: If you don’t love molasses, stay away from this cake. With ¾ cup of molasses, that rich, dark flavor definitely takes center stage. It is warmed with the spices of cinnamon, ginger and cloves.
  • Texture: There is buttermilk and sour cream in the cake batter, which helps to yield a very tender, moist cake.
  • Method: This bakes in a 10×15″ sheet cake pan with at least 1″ sides. You can bake it in an 11×17″ pan as well, it will just be slightly thinner.

What is molasses?

Molasses is one of the key flavors of this cake, but what exactly is molasses and what does it taste like?

Molasses is a byproduct of sugar production and can be from sugar cane, sugar beets or grapes. It can come in several different colors from lighter brown to very dark, and that color difference comes from how many times it is boiled. The more it is boiled, the darker it becomes. (source)

The darker molasses products, such as blackstrap molasses, is bitter in flavor. I purchase unsulphured molasses. Grandma’s molasses is my favorite brand.

Baking Tips

  • Bake in a 10×15″ sheet cake pan with 1″ sides. Please note that this is the size I used and the pan was very full. The cake rose slightly but did not overflow the edges of the pan. Use an 11×17″ sheet cake pan if you are concerned about the cake overflowing. It will be slightly thinner this way and may cook a few minutes faster.
  • Line the bottom of the sheet cake pan with parchment paper if you’d like to remove it easily.
  • The ingredients will mix together best if they are at room temperature. This is especially important for the butter and the eggs.
  • Once all of the ingredients are in the bowl, don’t overmix the cake batter. This will ensure the cake stays tender and soft.
  • The frosting makes enough to put a thin layer of frosting all over the top of the cake. If you’d like a thicker layer of frosting, double the recipe.

For the frosting:


Make the cake:

  • Preheat oven to 350º Fahrenheit. Spray an 10×115” baking pan with cooking spray. Line the bottom of the pan with parchment paper.
  • Cream together butter and brown sugar until light and fluffy, about 1-2 minutes.
  • Stir in eggs, sour cream, and vanilla extract.
  • In a separate bowl add in flour, baking powder, salt, cinnamon, ginger, and cloves.
  • In another bowl whisk together molasses and buttermilk until completely incorporated.
  • Mix half of the dry ingredients into the batter, alternating with half of the molasses, mixing after each addition until all the ingredients are incorporated together. Do not overmix.
  • Pour the cake batter into the prepared baking pan. Bake for 18-20 minutes or until the cake springs back when you touch the center. (Or a toothpick inserted in the center comes out clean.)
  • Allow the cake to cool on a wire rack.

Make the frosting:

  • In a large bowl, cream the cream cheese and butter until smooth.
  • Add the vanilla and molasses. Mix well.
  • Add in 1 ½ cups of powdered sugar and mix well until combined. Then add the remaining ½ cup of powdered sugar until the frosting is a good spreading consistency.
  • Spread the frosting using an offset spatula over the cooled cake. Sprinkle with cinnamon if desired.
  • Slice into 24 squares and serve.
  • Store any extra cake in an airtight container at room temperature. The cake freezes well also.
