Snickerdoodle cookies are great, which means that snickerdoodle cupcakes are awesome. Especially these, as they not only contain plenty of cinnamon, vanilla and brown sugar like the cookies, but they are vegan. This means that those with egg and dairy allergies can eat them as well. Once these cupcakes are baked and have cooled, top them off with some vanilla buttercream frosting and a sprinkling of cinnamon sugar to enhance the flavor and make them even more irresistible. Yum!
