This wonderful no bake lemon tart is an ode to all things lemon. The cookie crumb crust is sweet and crunchy, the lemon filling is refreshing and the lemon syrup mirror glaze elevates the dessert to super fancy heights. Additionally, this gluten free no-bake dessert is incredibly easy to prepare, and has a dairy free option. NOTE: The recipe below is for a 8 1/3 inch (21 cm) diameter round cake pan, about 1 1/2 inch (4 cm) deep. The prep time does not include refrigeration time.
