Delicate Muffins

I found this in one of my Mom's cookbooks when I was a teenager.  My favorite muffin, very simple and very easy to dress up.

Delicate Muffins
2 c all-purpose flour
4 t baking powder
1/2 c sugar
3/4 c milk
1 egg, beaten
1/4 c melted butter

Combine dry ingredients and whisk. Add wet and stir gently to combine, do not over mix.
Bake at 400F for 20 minutes - until just brown.  Makes 12.

My Own Variations:
Cranberry-Orange 

1-2 tablespoons fresh cranberry orange relish
1 c dried cranberries (orange flavored or otherwise, soaked in warm water before to plump).

Apple-Yogurt
1 apple, chopped small
1/2 c sliced almonds
1/2 t vanilla
1 c plain greek yogurt
(substitute 3/4 c milk with 3/4 c water)
