I tried this recipe early this morning. It's so easy, you just won't believe it. These muffins are so dense and old fashioned, that others will think there are more ingredients than they contain. I think they're nutritious as well.
Mix the canned pumpkin with the dry cake mix (just the dry cake mix).
Add the walnuts and stir gently. I soak the raisins in hot water for a few minutes, so they will plump up a little. Drain raisins and add to the mixture. Use an ice cream scoop to portion each muffin.
Put batter in paper lined muffin tins (I used regular tins), and bake at 350 degrees for about 25 minutes. Remove from the oven and take out each muffin to cool, or eat them while their warm. Either way they are delicious.
You may use a mini muffin pan lined with papers. If so, please check the time by testing for doneness. It may be about 12 to 15 minutes. Insert a tooth pick in a muffin, to make sure it's done.
