Perfect for St. Patrick's Day! If you'd like to tweak the green or try a different color — say pastel pink, yellow, or blue for Easter — you can see this homemade food coloring chart. It's is the basis for the coloring in this recipe.
Makes 36 individual cookies or, with filling, 18 sandwich cookies.
Preheat oven to 350 degrees Fahrenheit.
In a mixer, cream the butter and powdered sugar on high speed until light and fluffy.
Add the cocoa, baking soda, salt, and chocolate extract and beat again until smooth.
With the mixer on low, add half of the flour and mix until incorporated, then add additional flour until a not-at-all-sticky dough forms.
Don't worry if it's a bit crumbly.
Divide the dough into three discs, then refrigerate for at least 15 minutes and up to 24 hours to firm the dough.
When ready to bake, set out two pieces of parchment paper.
Work with each disc individually and keep the other discs in the fridge until needed.
Roll each disc flat between the sheets of parchment paper until it is between 1/4-inch and 1/8-inch thick (about the thickness of two pennies).
Cut out 2-inch round circles with a cookie cutter and place the cookies about one inch apart on a baking sheet lined with a silicone liner, parchment paper, or your favorite liner.
Bake for 7 to 9 minutes until cookies appear dry on top, then let cool 2 to 3 minutes on the baking sheet before transferring to a cooling rack to cool completely.
Place palm shortening and powdered sugar in the bowl of an electric mixer, then gradually bring the mixer up to high speed.
Beat until fluffy, adding more powdered sugar a tablespoon at a time if necessary to firm the mixture.
With the mixer on low, add in the homemade green food coloring and the peppermint oil a drop at a time, stirring until the mixture is homogenous, adding more color and flavor as desired.
Use filling immediately or store in the refrigerator for up to 2 weeks.
Bring the mixture fully to room temperature and remix if the colorant has seeped out of solution.
To fill a cookie, invert one cookie, then place 1 tablespoon of filling on that cookie.
Top with a second cookie and press lightly to bring filling just to the edges.
