Gluten Free version of Mother Mae's famous recipe. Mother Mae is a Scottish relative. Her secret to perfect shortbread was her vanilla infused sugar and a touch of rice flour -- her picture graces each box. Each box will fill two of our Shortbread pans with buttery, mouthwatering shortbread. All you do is add two sticks of unsalted butter and blend, press the mix in the pans and bake. How easy is that?
