Celebrate the holiday season with soft Mexican chocolate thumbprint cookies. One of my favorite things to do during the holidays is baking cookies with my children so we can share them with friends, family, and neighbors. These soft Mexican chocolate thumbprint cookies are my favorite cookies to prepare and I can make them anytime of the year. The sweet Mexican chocolate with a light touch of cinnamon will please everyone. Your home will never feel cozier than with the heat of the oven and the delicious aroma of vanilla spread throughout.
