I tried this yesterday and mine came out pretty bad.
The texture was fine, they were just kinda bland.
One thing I messed up on was I didn't have whole wheat PASTRY flour, so I used half whole wheat/half regular flour. I guess if I put icing on them they'd be OK. No, nevermind. they are pretty awful. I took half the batch to my friend's and told her kid's they were cookies
they gobbled them up. At least i know where to dispose of unwanted baked goods!
I realized I had a LOT of pumpkin left in the can (one of those big cans - 30oz or something) so I also made a loaf of bread and pumpkin cake. Those turned out delicious, but weren't vegan.
