Molasses cookies - Do I need to start over? I am making molasses cookies. I accidentally put a cup of sugar in the dry ingredients, when I was only supposed to have a cup of sugar creamed with shortening. Should I throw out my dry ingredients and start over or can I keep it and maybe my cookies will just be extra sweet?

Here is the recipe:

Ingredients:
1 cup shortening
1 egg
3/4 tsp vinegar
3 cups sifted flour
1 tsp salt
1 cup sugar
1/2 cup molasses
3/4 cup evaporated milk
3 tsp soda powder
1 tsp cinnamon

Cream shortening and sugar. Add egg and molasses, beat well. Stir in vinegar and milk. Mix and sift dry ingredients. Add to mixture. Drop from teaspoon on greased baking sheet. Bake at 350F for about 15 minutes.
You do not need to start over. The texture will be a little different than the original recipe but mixing the dry ingredients is not a huge mistake. Go ahead and bake the cookies according to the remaining recipe.
