Line a muffin pan with 6 silicone liners. Set aside.
In a microwave safe bowl, microwave the white chocolate chips and coconut oil in 30 second intervals, mixing until smooth.
Scoop around 1 Tablespoon of the melted white chocolate in each of the prepared muffin cups. Using the back of a spoon, drag some of the white chocolate up the sides.
Add around 1 teaspoon of crushed Oreos on top. Top the crushed Oreos with around 1.5 teaspoons of Nutella.
Divide the remaining white chocolate on top of each cup and spread to coat. Sprinkle the remaining crushed Oreos on top and place in the fridge until the chocolate has set.
