Lemon Cupcakes with Lemon Frosting

In search for a vegan lemon cupcake that could possibly replace the delicious Lemon Creme Lemon Cupcakes, I found a recipe at Vegan Cupcake Recipes. The problem is that the recipe is slightly poorly written and there's no creamy center like the cupcakes I've made. In addition, the images shown look like there's a lemon custard in the middle, but that's clearly added in for the photos and the recipe for it is not given. All those drawbacks aside, the cupcakes are delicious. I've fixed the recipe so they issues should be less of a problem. I'm still on the hunt for a vegan cupcake that has all the components of a lemon cream lemon cupcake.

Ingredients:
1 cup vegan margarine, softened
2 cups organic unbleached sugar
1/2 cup non-dairy yogurt
1/4 cup applesauce
2 teaspoons grated lemon rind
1 teaspoon vanilla
3 1/2 cups all-purpose flour
2 teaspoons baking powder
1 teaspoon baking soda
2 cups vegan sour cream

Frosting
3 tablespoons vegan margarine, softened
2 1/4 cups organic unbleached sugar (what the recipe calls for, but I need to try it with powdered sugar)
2 tablespoons lemon juice
3/4 teaspoon vanilla
1/4 teaspoon grated lemon rind
1-2 tablespoons soy milk (or other non-dairy milk)


Directions:

1. In a mixing bowl, cream margarine and organic unbleached sugar.
2. Mix in yogurt and applesauce.
3. Add lemon peel and vanilla, and continue to mix well.
4. In a second bowl, combine dry ingredients. 
5. Add to creamed mixture alternately with sour cream (batter will be thick).
6. Fill greased or paper-lined muffin cups with 1/4 cup of batter.
7. Bake at 350 for 25-30 minutes or until a toothpick inserted near the center comes out clean.
8. Cool for 10 minutes; remove to wire racks to cool 
9. Frosting:
10. Cream margarine and organic unbleached sugar in large mixing bowl. 
11. Add lemon juice, vanilla, lemon peel, and soy milk; whip until smooth. This may take awhile as I never got it with granulated sugar to be smooth.
12. Frost cupcakes.

Notes:

• As I noted, either powdered sugar needs to be used in the frosting, which I haven't tried yet, OR you have to whip for a very long time to get nice smooth frosting.
