Notes

*This recipe was written using an average of the dip and sweep method for measuring flour and the spoon and level method. If you are using a scale, you will need to add 3/4 oz or 22 g  to the measurement for each cup of flour.
Expert Tips:
  • Make sure that you use culinary grade lavender for this recipe!
  • Be careful to not over mix the cookie dough.
  • Don’t skip refrigerating the dough! It needs to be cold so it will cut.
  • In a hurry? You can freeze dough for 15-20 minutes instead of refrigerating!
  • To get evenly sized cookies, use a ruler or tape measure to measure and mark the dough at ¼ inch increments.
  • Make sure you take the cookies out of the oven just as they start to turn color. They don’t need to be browned!
  • These cookies taste better after they’ve cooled.
