1In a large mixing bowl, combine the butter, brown sugar, and the 1/2 cup of granulated sugar. Beat at medium speed until mixture is light and creamy.
2Add the egg, vanilla extract and salt; continue beating until well mixed.
3Add 1 cup of flour and the baking soda to the bowl, and beat on low speed until ingredients have been mixed together well.
4Add the remaining cup of flour; beat on low speed until it has been thoroughly mixed together.
5At this point you will need to refrigerate the dough (in a bowl covered with aluminum foil), so the dough firms up enough to shape into dough balls. This may take anywhere from 1-2 hours. (I let mine set overnight in the refrigerator, so I can bake mine the next day, and when I have the time.) I then let the dough sit on the counter (in the bowl covered with foil) for an hour or two before making it into cookies.
6When ready to bake the cookies, heat your oven to 350º F. And in a shallow bowl, combine the 1/4 cup of granulated sugar, and the tablespoon of ground cinnamon.
7Shape the cookie dough into 1-inch balls. (I used a small cookie scoop which is equivalent to 1 tablespoon, to make each cookie, then shape the cookie dough into 1" balls.)
8Roll the dough balls in the cinnamon sugar mixture, then place them 2-inches apart onto either ungreased baking sheets, or baking sheets lined with parchment paper. (I prefer to line my baking sheets with the parchment paper.)
9Bake the dough balls for 10 minutes, and after removing baking sheet from the oven, immediately press 1 chocolate star in the center of each cookie.
10Let the cookies sit for 1-minute on the baking sheet, then remove the cookies and place them on a wire rack to cool completely.
11To store the cookies: I place the cooled cookies onto clean baking sheets in a single layer, then place the baking sheets in the freezer, until the chocolate star is firm. I then place the cookies in a cookie tin or in a Tupperware container, and store the cookies in the freezer. These cookies do keep well for quite sometime in the freezer. When ready to serve, just take out as many cookies as needed, and let them sit for a bit before serving. (About 5 minutes. Providing you can wait that long!)
