These super soft lemon sugar cookies have the best light and fluffy sugar cookie texture with a subtle brightness from fresh lemon zest and juice. They are easy to make - with no rolling or cutting required. Enjoy them as they are, or top them with lemon buttercream frosting for an extra special treat!
In a small bowl (or your mixing bowl) rub together granulated sugar and 2 teaspoons lemon zest until a sand-like mixture forms. This releases the oil in the zest to infuse the lemon flavor throughout.
In the bowl of a stand mixer, add the lemon zest and sugar, powdered sugar, and butter. Cream together butter and sugars until pale in color and fully combined (like a paste). Add oil, eggs, vanilla extract, and lemon juice, mixing until combined.
In a separate mixing bowl, sift together flour, cream of tartar, baking soda, and salt. Mix the combined dry ingredients into wet ingredients until just combined.
Chill the dough for at least 30 minutes. This helps the cookies hold their shape; if the dough isn't too warm, you can bake them right away if you don't mind a little extra spread/thinner cookies, although the chill is recommended.
20 minutes before baking, preheat the oven to 350°F and line a sheet pan with parchment paper. Pour a small amount of granulated sugar into a small bowl for later.
Dollop a scoop (#40 scoop) or 1 1/2 tablespoons of batter about 2 inches apart on the prepared baking sheet. Dampen a flat-bottomed glass with water, then dip in a small bowl of granulated sugar. Gently press each cookie dough ball with the bottom of the glass approximately halfway down, about 1/2 inch thick. Dip the glass back in the sugar between each cookie to recoat.
Bake for 7-10 minutes, or until cookies are just beginning to barely turn golden brown around the edges. See notes about baking sheet type.
Let the cookies cool for 1-2 minutes on the baking sheet until set up enough to transfer to a cooling rack. Store cooled cookies in an airtight container at room temperature for up to 4 days.
Frosting: In the bowl of a stand mixer, cream butter until smooth. Add juice and vanilla extract to combine. Rub the zest with the powdered sugar for additional flavor (optional) then, in 1/2 cup increments, add the sugar to the butter, beating between each addition until smooth. Continue working until light and fluffy, approximately 2-3 minutes on medium speed. Spread on cooled cookies.
Notes
Lemon Extract: replace half of the lemon juice with lemon extract for an even brighter lemon flavor.
Baking Sheet: A light-colored (aluminum) sheet pan will require more cooking time than a darker-colored sheet pan. If using a darker-colored baking sheet, you will likely want to only bake the cookies for 7 minutes - no longer.
