(Request) Starbucks Seasonal Cookie

I can’t figure out if it’s a shortbread, or a shortbread like recipe with egg in it. And do they use White chocolate for the decoration?! Or is it Candy Melts. I tried twice and think there’s a bit of lemon mixed with vanilla as the flavouring. I just can’t get the texture right with the recipe I’ve tried ( basic shortbread no egg, good pinch of salt added, small amount of lemon zest, vanilla extract). Thank you for any insight!! via /r/CopyCatRecipes https://ift.tt/2u83cmr
