30 Mug Cakes - Pumpkin Walnut Muffin - #6

This recipe took a couple tries to get it right.  I am finding it hard to add wet ingredients,  like the pumpkin, without getting  a mushy muffin.  Here is my final recipe, that I thought tasted very good.

Pumpkin Walnut Muffin

5 Tbs. flaxseed meal
1 Tbs. sweetener
1/2 tsp. baking powder
1/2 tsp. cinnamon
dash of cloves
dash of nutmeg
2 Tbs. canned pumpkin
1 Tbs. butter, softened
1 egg
1 Tbs. walnut pieces

Mix all the ingredients together and pour into muffin cups.  Bake at 350 degrees for 25-30 minutes.  I like to sprinkle them with powdered sweetener when they are done.
