Lemon Half Moon Cookies. The classic New York City cookie with a blast of citrusy lemon flavor. Soft baked cookies with a cake-like texture, topped with the classic frosting of half vanilla and half lemon! These cookies are light and airy and packed with mouth puckering lemon flavor!
So I did not realize that half-moon cookies were only a New York thing until I left upstate New York and could not find them anywhere! So I decided to make my own and figured I could have some fun with it. Since spring is right around the corner, I am craving lemon! If you are looking for more lemon recipes check these out:

OTHER HALF-MOON COOKIE FLAVOR COMBINATIONS TO TRY
- Chocolate and vanilla. You could always stick with the basics and go with half chocolate frosting and half vanilla frosting. It is kind of plain but there must be a reason it has stayed iconic for all these years.
- Strawberry and lemon. Think of a strawberry lemonade type flavor. Half of the cookie will have lemon frosting and the other half of the cookie will have strawberry frosting. Delicious!
- Peanut butter and jelly. Half peanut butter frosting and the other half can bee a jelly based frosting of your choice like grape jelly or strawberry jelly. Honestly this sounds amazing!
KEY INGREDIENTS AND SUBSITUTIONS
- BUTTER. The salted butter gives these cookies a soft buttery taste and texture. That extra layer of salt will balance out the sweetness perfectly.
- SUGAR. White sugar gives these cookies the best texture and perfect level of sweetness.
- SOUR CREAM. This is a key ingredient. The sour cream makes these cookies SUPER moist and airy.
- LEMON. This adds a bright citrus flavor. Use the zest in the cookies and the juice in the frosting. If you don't want to juice lemons, you can use bottled lemon juice.
- POWDERED SUGAR. Using powdered sugar makes for a velvety smooth frosting.
- CORN SYRUP. The corn syrup is important in making the frosting hold up.
- YELLOW FOOD COLORING. Totally for decorative purposes. This makes the cookies fun and colorful and matches the lemon flavor. I would say start with 4 drops and add more if desired.

BAKING TIPS
