My mom used to make these very delicious cupcakes.
1 c sugar

1 ½ c flour

¼ c dry unsweetened cocoa, preferably Dutch Process

½ t salt

1 t baking soda

5 T oil (I use grapeseed oil, not too bad for you, and neutral in flavor)

1 t vanilla

1 c h2o

1 T vinegar

Filling: 8 oz. softened cream cheese, 1/3 c sugar, 6 oz. semisweet chocolate chips, 1 beaten egg, dash o’ salt

Chopped walnuts, sugar

Cupcakes: sift dry ingredients together, blend wet ingredients, add wet to dry ingredients. Fill cupcakes 1/3 full. Blend filling ingredients, then drop 1 T in each cupcake. Sprinkle with chopped walnuts and a bit of sugar. Bake at 350 F for 20-25 minutes. Makes about 2 dozen.
