I had some left over mashed some pumpkin after making the Chocolate Pumpkin Loaf from the Post Punk Kitchen website (it was delicious by the way but I forgot to photograph it).
So the next day I decided to try these Pumpkin Oatmeal Cookies (also from the Post Punk Kitchen). I made a half batch (as I only had half a cup of mashed pumpkin) but it still made heaps of cookies. I think you would only want to make a full batch if you planned on sharing them. As this batch was eaten entirely by Dear Husband and myself, half the amount was definitely enough!
The only changes I made to the recipe were to leave out the flax seeds (I didn't have any), substitute the walnuts for choc chips and to add 1/4 teaspoon of ground ginger. The result was quite yummy but my cookies turned out quite soft and cakey. Like a cross between a cookie and a scone - but quite delicious. I think they would be great with the walnuts too but I was more in the mood for chocolate than walnuts at the time. I plan to try them with the flax seeds next time.
