Preheat oven to 400 F. (200 C.), line a baking sheet with parchment paper and set out 2 sticks (8 oz.) of butter: one for the scones and one to soften for the honey butter. Chop sticks into smaller pieces to help them soften faster.
Into a food processor, add 2 tbsp. dry culinary lavender and ⅓ cup white sugar. Process on “puree” for 30 seconds until lavender is well chopped.
In a mixing bowl, add your lavender sugar mixture, 2½ cups flour, 1 tsp. baking powder, 1 tsp. baking soda, 1 tsp. lemon zest and ½ tsp. salt. Gently mix with a whisk or spoon. Add 4 oz. butter (1 sliced stick) into the mixing bowl. Use your hands to mix into a crumbly dough. You don’t need it to be completely solid – in fact, you don’t want it to be. You want tiny pieces of butter to remain.
In a separate bowl, add ¼ cup heavy cream, ⅓ cup lemon juice, 1 tsp. real vanilla extract and 1 beaten egg. Pour into the crumbly dough bowl. Stir with a wooden spoon until thoroughly mixed.
Add ¼ cup flour to a small bowl and get your hands nice and floury. Pick up enough dough to make a ball that’s not quite as large as a baseball, but not as small as a golf ball. Quickly roll and place on parchment-lined baking sheet. Repeat with your remaining dough.
Separately beat 1 egg, and brush each uncooked scone. Sprinkle each with sugar. Bake for 20 minutes. Allow scones to cool for 5-10 minutes before serving.
To make honey butter, simply mix softened butter with 1 tsp. honey. If you want to make it into a shape, simply spoon into a cookie cutter on a plate, place in the freezer for 10 minutes, and it will easily slide right out.
