How to Make Lemon Sheet Cake and Frosting
- Mix first three ingredients together and spread into a lightly greased 13 x 15" or 15 x 18" sheet cake pan. Bake 30 - 35 minutes at 350 degrees.
- Frosting: Mix frosting ingredients together and frost sheet cake. Cool cake before frosting. This is just cut into bars and is more like a lemon bar. Very tasty!
