Not only for Christmas, but another option for birthday cake.
I made this gingerbread barn last Christmas, but I tought it would be a good idea for a birthday cake.
Cut out cardboard to shape a barn.
Cut the pieces in paper to shape the gingerbread dough (I used recipe from Food Network).
Then bake and cool of the pieces.
Prepare different color frosting, and decorate the pieces of cookie in a flat surface. Let it dry.
Glue the pieces together with frosting, using props to hold, and dry overnight.
