A delightful dessert bar combining a rich chocolate cookie crust with a luscious chocolate topping.
Preheat your oven to 350°F (175°C).
Preheating ensures even baking from the start.
Crush the chocolate cookies into fine crumbs using a rolling pin or food processor.
Ensure the crumbs are evenly sized for a consistent crust.
Combine the crushed cookies with melted butter in a mixing bowl and mix until well combined.
Mix thoroughly to ensure the butter coats all the crumbs.
Press the cookie mixture evenly into the bottom of a 9x13 baking pan.
Use the back of a spoon to press the mixture firmly.
In a microwave-safe bowl, combine the sweetened condensed milk and 1 cup of chocolate chips. Heat in 30-second intervals, stirring in between, until smooth.
Stirring prevents the chocolate from burning.
Pour the melted chocolate mixture over the cookie crust, spreading it evenly.
Use a spatula for an even layer.
Sprinkle the remaining chocolate chips over the top.
Press lightly to ensure they stick to the surface.
Bake in the preheated oven for 10 minutes.
Keep an eye on the edges to avoid over-baking.
Cool the bars in the refrigerator for at least 2 hours before cutting into squares.
Chilling helps the bars set for cleaner cuts.
