Crush lavender using a pestle and mortar. Set aside. In a medium sized bowl, combine crushed lavender, all-purpose flour, almond meal, and salt.
In a large bowl, cream butter, sugar, and vanilla extract until light and fluffy. Stir in flour mixture and milk. Knead until dough comes together, about 1 to 2 minutes. Wrap in plastic and chill for 15 minutes.
Very lightly oil the recessed image side of cookie tile. Wipe off any excess oil with paper towel. Dust with flour and tap to remove excess. You will need to re-flour the tiles each time you press a cookie but not re-oil.
Divide dough into 8 equal portions. Roll into little logs about 3 inches long.
Lightly flour working surface. Evenly press a prepared tile onto each piece of dough. Extra dough will squeeze out from under the tile.
Cut around tile with a small sharp knife and lift tile. With a flat edge spatula, lift pressed cookie onto baking sheet.
Bake in a 350°F (180°C) oven for 12 to 14 minutes or until edges are lightly brown.
Transfer to a wire rack to cool completely.
Notes
**Use cookie cutter if you do not have cookie tiles. Roll out the dough on a lightly floured surface to about ¼ inch thick. Cut out shapes with cookie cutter.
