Mix all ingredients in a large bowl until well combined. Form the cookie dough into a ball, flatten it a bit to a disk shape, wrap it in plastic wrap, and refrigerate for about 30 minutes.
Preheat the oven to 350°F/180°C and line the baking sheet with parchment.
Remove the dough from the refrigerator and unwrap it. Roll it out between two parchment papers to 1/4 inch thickness. With a 2-inch round cookie cutter, cut out the cookies and place them on the baking sheet.
Bake for 10-11 minutes or until they get golden brown color.
Let cool on the baking sheet completely before dipping into the chocolate.
Melt the chocolate in the microwave for 30 seconds (in the microwave-safe bowl) or use a double boiler. Dip each cookie bottom to melted chocolate, and place it back bottom down on the parchment.
Let the chocolate set for an hour on the cookies before serving.
