Preheat oven to 400°F (200°C). Line a baking sheet with parchment.

Pulse sugar and lavender in a food processor until finely blended.

Whisk flour, baking powder, baking soda, salt, and lavender sugar in a large bowl.

Cut in cold butter until the mixture resembles coarse crumbs.

In a separate bowl, whisk heavy cream, lemon juice, zest, vanilla, and eggs.

Add wet ingredients to the dry mixture and stir just until combined.

Pat dough onto a floured surface, 1-inch thick. Cut into wedges or rounds.

Place on baking sheet. Brush tops with cream, sprinkle sugar.

Bake 15–20 minutes until golden brown.

While baking, whip butter and honey until smooth.

Cool slightly and serve with honey butter.
