With just a hint of sour cream and perfect crackly tops with a double coating of sugar, these chewy cookies will turn even the gloomiest of days into a celebration. It’s difficult to get a sense of the size of these cookies in a photograph. We affectionately refer to them as being “as big as your head.” However, they’re about five inches wide. They are light and have a wonderful texture with just enough chew to them before they melt in your mouth. Always one to make an extra effort, my mother has added colored sugar to the dusting on the top. This adds an attractive bit of “confetti” and makes these cookies as attractive as they are delicious.
