Step 1

Preheat oven to 350 F. Line a baking sheet with parchment paper.

Step 2

Place sugars in a medium mixing bowl and add 1 tbsp of lemon zest. Rub with your fingers until the zest has become flavorful and mixed into the sugars.

Step 3

Add the butter to the bowl and beat together until light, about 3 minutes. You can also mix this by hand. Add lemon juice and egg yolk and mix again.

Step 4

Slowly mix in baking soda, salt, baking powder and flour until combined.

Step 5

Scoop the dough into 5 large balls, I used a 3 tbsp scoop, and roll in extra sugar. Place cookie dough balls on your lined baking sheet.

Step 6

Bake the cookies for 11-13 minutes. You're looking for a nice light golden brown around the edges, and some crackling along the top.
