Preheat oven to 350 degrees Fahrenheit
Mix your wet ingredients together in a glass bowl. I used a whisk, but you can also use a wooden spoon.
Add in your dry ingredients and mix with a wooden spoon.
Cover the dough with plastic wrap and place it in the fridge for about 30 minutes. The key is to make sure the dough is chilled and firm so that you can easily roll the dough into small balls.
After 30 minutes, take the dough out of the fridge scoop the dough into small little balls and placed on a parchment lined cookie sheet.
Bake the cookies for 8 minutes. Take the cookies out of the oven and press each of the cookies flat with a spatula then the cookies back into the oven for 45 seconds.
After the cookies are done in the oven make sure you put them on a cookie sheet to cool completely completely while you make your frosting. For the frosting just hand mix, butter, powdered sugar, and lemon in a glass bowl.
Make sure your cookies are completely before you start adding the frosting to the middle of of each cookie to make a sandwich.
Enjoy.
