In the bowl of a stand mixer fitted with the paddle attachment, combine room temperature butter, sugar, brown sugar, and lemon zest. Mix together on medium speed for 3-4 minutes, until the butter is lightened in color and fluffy. Reduce mixer speed to low speed and add egg and egg yolk and mix to combine, ensuring the eggs are well incorporated, about 1 minute. 1 cup Salted Butter1 1/4 cups Sugar1/4 cup Brown Sugar3 tbsp Lemon Zest1 large Egg1 Egg Yolk
Scrape down the sides of the bowl and add vanilla extract, lemon emulsion, and almond extract. Mix until combined. 2 tsp Vanilla Extract2 tsp Lemon Emulsion1/4 tsp Almond Extract
Add bread flour, all purpose flour, baking soda, and kosher salt. Mix until just combined and there are no patches of flour anymore. 1 3/4 cups Bread Flour1 1/4 cups All Purpose Flour1 tsp Baking Soda1/2 tsp Kosher Salt
Remove the bowl from the stand mixer and use a rubber spatula to fold the chopped white chocolate (or white chocolate chips) into the batter. (totally optional, but I like to reserve a few pieces of white chocolate to press into the cookies) 4 oz White Chocolate
Use a large cookie scoop to scoop the cookie dough into about 12-13 dough balls. Roll into balls and press any leftover white chocolate into each cookie dough ball (optional). Refrigerate uncovered for 1 hour.
Preheat the oven to 350 degrees F. In a small bowl, mix together lemon zest and sugar in a bowl. Rub the lemon zest into the sugar until it becomes fragrant and the sugar takes on a pale yellow color. Roll each cookie ball into the sugar mixture, ensuring the whole dough ball is coated. 1/2 cup Sugar2 tbsp Lemon Zest
Bake for 5-6 cookies at a time, spacing about 2 inches apart, for 13-14 minutes, until the edges are set and the center is puffed. Fresh out of the oven, scoot a large circular cookie cutter or small bowl around the cookies to give them a perfect circle shape.
Let the cookies cool on the baking sheet for 10 minutes then remove onto a wire rack to cool completely.
