Soft Cream Drop Sugar Cookies

Got to admit, it's been a LONG while since I have baked these cookies, but gotta let you know I put 4 stars beside it in the book when previously making them! Gonna HAVE to get busy and make these before Christmas for sure!

2 cups granulated sugar
2 eggs
4 cups flour
1 teaspoon baking soda
1 teaspoon salt
2 teaspoons baking powder
