I did it!! Here's the original recipe:

1 cup almond flour
1 tsp cinnamon
1/2 tsp ground cloves (or 2 tsp Allspice instead of cinn or cloves)
1/4 tsp salt
1/2 tsp baking powder
1/2 tsp baking soda
24pks splenda (OR 1/2 cup davinci SF syrup and 6pks of Splenda)
3 tblsp chopped walnuts

Then mix:
1 cup mashed pumpkin
2 eggs
1/2 cup oil

Mix dry into wet and pour into sprayed 9x13 inch pan. Bake 350 for 30-40 min. Let cool then frost.

Here's what I did to get rid if the wet mush texture:

I didn't use any DaVinci; used 1/4 tsp.Sweetzfree and a dash of vanilla extract.
Put only 3/4 cup pumpkin in and used only 1/3 cup of oil.

Baked for 40 minutes in a square pan. They came out exactly like a nice cakey bar!!! Oh, and I DID use almond flour.
