Grandpa Earl's Housekeeper's Whole Wheat Muffins

1 cup brown sugar
1/2 cup butter or oil
1 egg
1 cup buttermilk (or if you don't have buttermilk, pour 2 TB vinegar into 1 cup measuring cup and fill the rest of the cup with milk.  Let sit a few minutes until soured).
1 tsp baking soda
1/2 tsp baking powder
1/2 tsp cinnamon
1/2 tsp vanilla
2 1/4 cups whole wheat flour
add chocolate chips or raisins, if desired (not part of the original recipe)

Mix all ingredients together and bake 15-20 minutes at 350 in greased or lined muffin tins.
Makes 18-20 muffins

Ann's notes: I put everything together and increase the cinnamon to 1 tsp.  I don't wait for the milk to sour, I just put the vinegar in the cup first and then add the milk, to make 1 cup. I use canola oil and will only put in 1/3 cup it will just make them a little crumblier.
