Beat the first 4 ingredients, add egg and mix thoroughly, add vanilla. Mix all dry ingredients separately then add to the rest and mix. Scoop out with a small ice cream scoop, or how ever you want to do it. I flatten these and generously sprinkle sugar on them. Bake on 325* for about 12 minutes and cool on wire rack. I like to place wax paper (or anything really) under them while they are cooling so that I can ice them and it will drip down onto the paper instead of making a huge sticky mess to clean up.
For the glaze, just mix all together until its a nice runny consistency and pour over cookies! ENJOY!
Lime Glaze
Juice of 1 lime
Zest of 1 lime
Enough powdered sugar to make the icing a nice consistency for glazing (a few cups)
I don't always measure stuff.... sorry!
