Preheat the oven to 350°F (175°C). Grease a mini muffin tin.

Slice the cookie dough into 24 equal slices. Press each slice into the bottom and up the sides of each muffin cup.

Bake the cookie cups for 8-10 minutes, or until lightly golden brown. Remove from the oven and gently press down the center of each cookie cup with the back of a spoon to create a well. Allow to cool completely.

In a medium bowl, whisk together the vanilla pudding mix and milk until thickened. Spoon the pudding into each cookie cup.

In a small saucepan, heat the heavy cream until just simmering. Remove from heat and stir in the chocolate chips until melted and smooth.

Spoon the chocolate ganache over the pudding-filled cookie cups.

Refrigerate the cookie bites for at least 30 minutes, or until set. Remove from the muffin tin and serve.
