Preheat the oven to 350°F
Place half of the chocolate (60g) and the oil or butter in microwave safe bowl and microwave in 15 second increments, stirring between, until the chocolate is melted and smooth
Stir the yogurt and vanilla into the melted oil and chocolate
Add the remaining ingredients to the bowl and mix until the dry ingredients are fully incorporated
Fold in the rest of the chocolate chips – at this point the dough can be baked into cookies or stored in an airtight container in the fridge for edible cookie dough*
For cookies, scoop onto a prepped baking sheet, then lightly press down to flatten each cookie as they don’t spread much while baking – wet your fingers, use gloves, or a piece of parchment or wax paper to shape the cookies and keep the mess to a minimum
Bake for 5-7 minutes, then let cool (either on the baking sheet or a cooling rack)
As the cookies are cooling, prepare the icing – or see below for other topping options – by melting all of the icing ingredients together in 10-15 second increments and stirring between until smooth and glossy
Once the cookies are cool, spread a layer (thickness based on preference) of the icing onto each cookie, then allow the cookies sit at room temperature until the icing has set – it’s set when the icing is firm to the touch and the cookies can be stacked without sticking to each other
