Frosted Lemon Sugar Cookies made by adding fresh lemon juice and zest to a simple sugar cookie dough. Easy Lemon Cookies piped with a super simple rosette, so they taste incredible and they're pretty too!
Prep: Preheat oven to 375 degrees F. Line a cookie sheet with parchment paper.
Dough: Cream together butter and sugar. Add egg, vanilla, sour cream, lemon juice and zest. Gently whisk together dry ingredients in a separate bowl.
Add ⅓ of the dry ingredients to butter mixture and mix to combine. Continue process, adding ⅓ of the dry ingredients at a time until it’s all mixed in.
Bake: Scoop out 1.5 TBSP of dough and roll into a ball. You can use a medium cookie scoop to make this process faster. Rolling the cookie ball is optional, but I wanted very pretty cookies, so I took the additional 5 seconds and rolled them individually. Place on parchment lined cookie sheet.
Place in the preheated oven and bake for 10 minutes. Let the cookies fully cool before frosting.
Lemon frosting: Mix butter, vanilla, milk, lemon juice and zest for 30 seconds with a mixer. Add in powdered sugar 1 cup at a time until you reach your desired consistency.
Transfer frosting to a piping bag with a closed star tip- I used a Wilton 2D. Begin piping in a tight circle in the middle of the cookie. Continue piping frosting in a circular motion until you reach the outside of the cookie. Frosting will set but I recommend not stacking cookies that have been frosted with a rosette so that you don't squish them. Serve cookies immediately and enjoy!
