Ingredients
4 tablespoons (2 ounces) unsalted butter, melted
1/3 cup (67 grams) granulated sugar
1/2 teaspoon culinary grade lavender buds
1 large egg yolk (no white)
1/2 teaspoon vanilla extract
3/4 cup (96 grams) all-purpose flour
1/4 teaspoon baking soda
1/8 teaspoon fine salt
Instructions
Preheat the oven to 350, and line a small baking sheet with parchment paper (or use a silicone mat).
Place the butter in a microwave-safe bowl, and melt it in the microwave in 25 second intervals until fully melted. Keep an eye on it because if it gets too hot, it will splatter.
In a small food processor, combine the sugar and lavender buds and pulse a few times to break the buds into small pieces. Cover the food processor while you pulse so the sugar doesn’t fly out.
Stir together the melted butter, lavender sugar, egg yolk, and vanilla extract. Stir very well to combine.
Next, sprinkle the flour, baking soda and salt evenly over the dough, and stir just to combine.
Press the dough flat and evenly in the bowl, and then divide it in half by eye. You should get 3 cookies from each half.
Evenly space the cookies on the prepared baking sheet.Bake for 10 minutes, until they spread, start to crackle and appear dry on top.
Let the cookies rest on the baking sheet for 2 minutes before moving them to a wire rack to cool completely.
