1. In a stand mixer, beat butter and sugar together. Add eggs, lemon
and lavender and beat to combine. Add flour, one cup at a time and
beat until well combined, about 3 minutes. Roll dough into a log on top
of a sheet of waxed paper, roll the log up in the paper, twist the ends
and refrigerate it for at least 3 hours.
2. Pre-heat the oven to 375F. Roll the dough out to 1/4in thick and cut into snowflake (or whatever you fancy) shapes. Transfer cookies to cookie sheet using a spatula. Bake for 10 minutes. Remove from oven and allow to cool slightly on pan before removing to a tea towel set on the counter to cool. If you are going to frost these, allow them to cool completely.
