Steps to Make It
1. Prepare the Base Layer
Crush the Biscuits: Place the butter biscuits in a food processor and blitz until they form a fine powder. Alternatively, place them in a zip-lock bag and crush them with a rolling pin.
Mix the Ingredients: In a large mixing bowl, combine the crushed biscuits, icing sugar, melted butter, milk, and cracked Oreo cookies. Mix well until all the ingredients are evenly incorporated. The mixture should have a wet, sandy texture.
Shape the Base: Line a 20×20 cm baking pan with parchment paper. Press the biscuit mixture firmly into the pan, ensuring an even layer. Use the back of a spoon or a flat spatula to smooth the surface.
2. Add the Chocolate Topping
Melt the Chocolate: Break the dark chocolate into pieces and melt it in a steam bath (double boiler). Stir occasionally to ensure a smooth consistency. Add the vegetable oil and mix until glossy and pourable.
Pour the Chocolate: Evenly pour the melted chocolate over the biscuit base. Use a spatula to spread it out if needed.

3. Set the Bars
Chill the Dessert: Place the pan in the refrigerator for 2–3 hours, or until the chocolate is fully set and firm to the touch.
Slice and Serve: Once set, remove the dessert from the pan by lifting the parchment paper. Cut into bars or squares using a sharp knife. Serve chilled and enjoy!
