Preheat your oven to 350°F (175°C) and line a cookie sheet with parchment paper.
In a small mixing bowl, cream together the softened butter and brown sugar for about 2 minutes until well combined.
Stir in the vanilla extract and cocoa powder until fully incorporated.
Add the flour, baking soda, and baking powder, mixing until a soft dough forms.
Chop the Simply Peanut Butter Date Bar into small pieces and fold them into the dough.
Scoop the dough onto the prepared baking sheet and shape it into a ball. Since the dough is slightly sticky, use a spatula to help form it.
Top with chocolate chunks and bake for 12 minutes.
Remove from the oven. While the cookie is still warm, place a bowl over the cookie and move it in a circular motion to reshape the edges into a perfect circle.
Let it cool slightly before enjoying your warm, gooey, double chocolate cookie!
For an extra indulgent experience, serve with a cold glass of milk or a scoop of vanilla ice cream.
