This is one of my favorite treats especially this time of year. I love pumpkin cookies and pumpkin roll. This recipe is the best of both. My mother in law made these the past few years and I can't get enough of them. She changes makes half of them with chocolate chips on top, and pits the frosting on the other half. So it is like having half a sheet of pumpkin cookies and half a sheet that taste like pumpkin roll.

Combine

6 Eggs
3 C Sugar
1 1/2 tsp Vanilla
1 lg can (29 oz) OR 2 small cans (15 oz) Pumpkin

Add

4 1/4 C Flour
1 Tbs Cinnamon
1 1/2 tsp Salt
1 1/2 tsp Baking Powder

Pour into a greased 13x18 Gelly pan. Sprinkle a cup of chocolate chips on half the sheet. The other side will have frosting on them. Bake at 350° for 40-45 minutes or until the center is firm, or a toothpick inserted in the middle comes out clean.
