I found my recipe and made substitutions where necessary.
Here is the recipe with my substitutions in parenthesis.
1/4 C margarine (I used butter)
1/2 C unsweetened applesauce (I have used cinnamon applesauce before too)
1/2 tsp salt
1 C sugar
2 C flour (I use whole wheat)
1 tbs baking powder
1 tsp vanilla
1/2 C soymilk (I use cow milk)
2 C blueberries, fresh or frozen
Mix all ingredients, except blueberries, in a bowl. Fold in blueberries. Put into muffin tin and bake at 350 for about 35 minutes.
