Preheat your oven to 350°F and line two baking sheets with parchment paper.
In a large bowl, cream together the softened butter, granulated sugar, and brown sugar until light and fluffy.
Beat in the eggs one at a time, then stir in the vanilla extract.
In a separate bowl, whisk together the flour, baking soda, salt, and culinary lavender.
Gradually add the dry ingredients to the butter mixture, stirring until just combined.
Fold in the chocolate chips and purple morsels by hand.
Scoop rounded tablespoons of dough onto the prepared baking sheets, spacing them 2 inches apart.
Bake for 10–12 minutes, or until the edges are lightly golden.
Allow the cookies to cool on the pan for 5 minutes before transferring to a wire rack.
