How To Make Butter Lemon Sandwich Cookies

Ingredients

For the Cookies:

• 1 ½ cup all-purpose flour
• ½ cup granulated sugar
• ½ tbsp lemon zest
• ½ cup (1 stick) unsalted butter
• 2 egg yolks
• ½ tsp vanilla extract

For the Lemon Filling

• ½ cup (1 stick) unsalted butter
• 1 ½ cups icing sugar
• 1 ½ tbsp grated lemon zest
• 1 tbsp freshly- squeezed lemon juice

 Directions:

1. Preheat the oven to 350 F degrees.

2. Place flour, granulated sugar, ½ tbsp lemon zest, and ½ cup butter into a food processor. Process until well mixed.
3. Lightly beat yolks and vanilla together. Then slowly pour into the food processor. Process just until dough forms; make sure not to over process.
4. Transfer dough onto a floured surface. With a rolling pin, roll dough to about ¼" thick (cookies have to be slightly thin because they will be doubled in thickness when sandwiched).
5. Form shapes with cookie cutter. With spatula, place on baking tray at least 1" apart.
6. Knead remaining dough together and repeat the rolling process until you have formed enough shapes.
7. Once ready, bake for around 10 to 15 minutes (depending on size) until firm. Do not brown the sides. Cool on a cooling rack.
8. In a clean bowl, beat all lemon filling ingredients with an electric mixer until creamy. Use a butter knife to spread filling on a cooled cookie, then sandwich with another. Repeat steps until all cookies are sandwiched.
