Preheat oven to 325°F (165°C)
In a bowl, whisk together Greek yogurt, egg, maple syrup, vanilla, and cocoa powder until smooth
Gently fold in the chocolate chips
Pour mixture into a greased ramekin or small baking dish
Bake for 28–32 minutes, until edges are set and the center is slightly jiggly
Let cool for 10 minutes, then chill in the fridge for at least 30 minutes (overnight for best texture)
Enjoy straight from the ramekin
