I had them last year. They are good.
If you can't get them, I can tell you a good recipe for pumkin cake. You can make them into muffins.
I make a yellow cake. Use the directions, but instead of oil, use one cup of pumpkin. Use four eggs and add vanilla instant pudding pack. Then put a little allspice, cinnamon, nutmeg and a pinch of ginger. I use a bundt pan or mini bundt pans for individual cakes, but you can use muffin tins too.
For icing, make a cream cheese frosting. Stick in the microwave till it's slightly pourable. Drizzle. Then I sprinkle chopped pecans over the top. YUM!
If you don't like cream cheese frosting, just dust with some powdered sugar.
