I love this elegant variation on classic shortbread, perfect for any spring occasion, even if that occasion is just having quiet cup of tea. Here's my recipe for vanilla lavender shortbread cookies.
In the bowl of a stand mixer fitted with the paddle attachment, cream together the confectioner's sugar and butter until light and fluffy. With the mixer running on low, slowly add in the flour, a little at a time and continue mixing until everything is well-combined. Add in the vanilla and mix until well-distributed. Feel free to add a tablespoon or two of almond milk at this point to make the dough come together if it's still a bit crumbly.
Add in the culinary lavender and mix until it's well-distributed throughout the dough.
Roll the dough out to 1/8" thickness and cut out cookies with cookie cutters. Continue re-rolling and cutting out cookies from the dough until all the dough has been used up.
Bake cookies on a silpat-lined baking sheet at 325° for 12 minutes, rotating the baking sheet halfway through.
Allow the cookie to cool completely on a wire rack. Meanwhile, make the glaze by combining the second amounts of confectioner's sugar and vanilla, along with the almond milk in a small dish. Mix until smooth and drizzle over cooled cookies.
