Preheat oven to 350 degrees F (176 C) and blitz Oreos in a food processor until a fine meal remains. Add melted coconut oil (or vegan butter) and pulse once more.
Cut 12 small strips of parchment paper (or use paper liners // adjust amount if altering batch size) and place them in a standard, 12-slot muffin tin. One at a time, hold down a strip in the center of the tin, add 1 generous spoonful of crust mixture, then use a small cup or your spoon to pack it down as evenly as possible. I like using a small glass because it packs it in really tightly and gets the top flat. Continue until all tins are filled and no crust remains.
Prepare ganache by bringing smaller measurement of coconut milk (3 Tbsp as original recipe is written // adjust if altering batch size) to a simmer in the microwave (30 seconds) or on the stove top in a small saucepan. Place the chocolate chips in a small mixing bowl and pour the coconut milk on top. DON’T touch for 3 minutes so it has a chance to warm the chips. Then stir gently until smooth. Microwave or set over a double boiler briefly if the chips didn’t fully melt.
