Preheat your oven to 350 degrees F. Line two baking pans with parchment paper, set aside.
In a stand mixer, using the paddle attachment, add in the butter and the powdered sugar and mix until creamed and combined.
Once it's combined, add in the rest of the ingredients for the cookies together. Make sure you scrape down the sides. Pause often to make sure you get all the ingredients well mixed. Once the paddle has pulled in all the dough, it is ready.
With a small cookie scoop (about 1 Tablespoon), scoop one cookie at a time. With your hands, take the dough and roll it into a ball.
Place the cookie on the baking sheet. With a ¼ teaspoon, press down in the middle to make an indent. I recommend putting some non-stick spray on the spoon, so it doesn’t stick to the dough.
Once they are all done, place them in the oven and bake for 15 to 18 minutes, until the bottom is a bit golden.
Meanwhile, prepare the ganache.In a small saucepan, heat up the whipping cream, but make sure it doesn't boil.
Place chocolate chips in a heatproof bowl. Once the cream is hot, pour in the chocolate chips. Let it rest for 2-3 minutes until the chocolate has softened.
Slowly stir until completely combined and all the chocolate has melted. Allow to cool for 10 minutes before using.
Place cooled ganache into a piping bag, then cut the tip off.
Once the cookies are completely cooled, fill the indents with chocolate ganache with the piping bag.
Let cool for a couple of hours in the refrigerator before serving.
Enjoy!
