Preheat oven to 350° F. Combine all of the crust ingredients in a medium bowl, press into 4 (4 inch) mini tart pans, transfer to oven and bake for about 10-15 minutes until golden. Remove and let cool.
Place the butter in a medium pot over low heat. Once melted remove from the heat and whisk in the confectioners, lemon juice, and lemon zest. Whisk in eggs and return to low heat. Cook, stirring, until it thickens. Remove from heat and divide between the tarts. Refrigerate for one hour.
When ready to serve top with raspberries.
