Before you start
Before beginning, ensure that all ingredients are measured and ready to be assembled. Preheat the oven to 350°F (175°C) to ensure it reaches the correct temperature before the bars are inserted. Prepare the baking dish by ensuring it is clean and dry.
Having all components laid out on your workspace will streamline the assembly process and allow you to build the layers quickly and efficiently without unnecessary interruptions during the preparation of the base.
Ingredients at a glance (5)
- 2 cups dark chocolate cookie crumbs
- 1 can (14 oz) sweetened condensed milk
- 1 cup white chocolate chips
- 1 cup dark chocolate chips
- 1/2 cup pink peppermint chips
Instructions
Assembling the cookie crust
- Prepare the baseSpread the dark chocolate cookie crumbs into the bottom of a 9x13 inch baking dish. Press the crumbs down firmly with your hand to form a solid, even crust layer.Look for The crumbs should be pressed into a compact and even layer covering the bottom of the dish.Tip Use the bottom of a flat measuring cup to help achieve a perfectly level and compact crust.
The cookie crust should form an even, compact layer covering the entire bottom of the baking dish. It should feel firm to the touch and appear uniform in color. Check that there are no gaps or loose crumbs remaining in the corners of the pan, as a consistent base is necessary to support the layers that will be added next. The mixture should be dark and ready for the liquid ingredients.
Layering the fillings
- Layer the ingredientsPour the sweetened condensed milk evenly over the prepared cookie crumb base. Sprinkle the white chocolate chips, dark chocolate chips, and pink peppermint chips over the top of the condensed milk.Look for Ensure the condensed milk covers the entire surface of the base to act as a binder for the chips.Tip Distribute the chips in a single layer to ensure they melt evenly during the baking process.
The sweetened condensed milk should be poured in a thin, even layer that covers the cookie base entirely. Ensure the chocolate and peppermint chips are distributed uniformly across the top, creating a visually appealing layer that spans the entire surface of the pan.
The chips should be placed in a single layer to ensure they melt consistently during the baking phase, preventing uneven textures or pockets of unmelted chocolate.
Baking and final cooling
- Bake and coolBake at 350°F (175°C) for 25 minutes or until the edges are golden and bubbling. Remove from the oven and allow to cool completely in the pan before slicing into neat squares.Look for The edges should look slightly toasted and the milk should be bubbling through the gaps in the chips.Tip Cooling the bars completely is essential to ensure they set properly and maintain their shape when sliced.
The bars should have a golden, bubbling edge with a set center. The chocolate and peppermint chips will have melted together to form a cohesive, glossy top layer. After removing from the oven, the bars will look slightly soft, which is normal.
They must remain in the pan until they reach room temperature, allowing the sugars and fats to solidify, which is the final requirement for achieving the perfect, clean slice.
Common mistakes
Avoid overbaking the bars, which can cause the sweetened condensed milk to harden too much or the chocolate to burn. Keep a close eye on the oven during the final few minutes of the baking time. Additionally, ensure the cookie base is firmly pressed into the dish; if the base is too loose, the bars will fall apart when removed. Finally, do not slice the bars while they are still hot, as they need time to set.
How to tell it’s done
The bars are done when the edges appear golden brown and the sweetened condensed milk is bubbling around the perimeter of the dish. The chips should be fully melted and integrated into the top layer.
Use a toothpick to check that the center is set; it should come out mostly clean, though some melted chocolate residue is expected. Allow the bars to rest for at least 30 minutes before attempting to slice them, as this allows the structure to firm up.
