Lemon slice and bake cookies are a simply, buttery cookie recipe with lovely lemon flavor. Easy to make ahead, these lemon shortbread cookies are perfect for parties & as gifts!
In a food processor or blender, pulse the flour, powdered sugar, salt and lemon zest until combined.
Add in the butter and pulse until sandy. Add in the egg yolk and lemon juice and then pulse until the dough comes together.
Remove from the food processor and form the dough into a 1.5″ wide log. Wrap in plastic wrap and chill until firm. (At least 2 hours, but up until 1 month.)
Preheat your oven to 350F degrees. Remove the cookie log from the fridge and then let it sit for about 5 minutes.
Cut the log in half. (I found it easier to roll/ cut when the log was smaller.)
Spread your turbinado sugar on a plate; roll cookie log over sugar to coat outside, pressing sugar onto entire surface.
Slice the log into 1/4″ slices and then arrange on a parchment-lined baking sheet.
Bake for about 13-15 minutes, until the cookies are golden brown around edges. Cool completely and ENJOY!
