Ingredients You’ll Need

For the Oreo Base

• 200 g Oreos (about 18 cookies), crushed – Forms a rich, chocolatey cookie crust.
• 60 g (4 tablespoons) salted butter, melted – Binds the cookie crumbs together while adding buttery flavor.

For the Filling

• 1 can (380 g) Carnation caramel – Creates a thick, creamy caramel layer that stays perfectly gooey.

For the Topping

• 200 g (1¼ cups) white chocolate chips – Melt into a sweet, creamy topping.
• 14 additional Oreos, broken into chunks – Add extra crunch and cookies-and-cream flavor.

Step-by-Step Instructions

Step 1: Prepare the Oven and Pan

Preheat your oven to 350°F (180°C) or 160°C fan.

Line an 8-inch (20 cm) square baking pan with parchment paper, leaving a slight overhang to make removing the bars easier.

Step 2: Make the Oreo Crust

Place the Oreos in a food processor and pulse until they become fine crumbs.

Alternatively, place them in a zip-top bag and crush them using a rolling pin.

Transfer the crumbs to a mixing bowl and stir in the melted butter until evenly coated.

Press the mixture firmly into the bottom of the prepared baking pan to create an even crust.

Step 3: Add the Caramel Layer

Pour the Carnation caramel over the Oreo crust.

Use an offset spatula or the back of a spoon to spread it evenly all the way to the edges.

Step 4: Sprinkle the White Chocolate

Evenly scatter the white chocolate chips over the caramel layer.

As the bars bake, the chocolate will soften and become wonderfully creamy.

Step 5: Add the Oreo Crunch

Break the remaining Oreos into large chunks.

Sprinkle them evenly across the top of the white chocolate chips.

This creates the signature crunchy topping.

Step 6: Bake

Bake for 30 minutes, or until the edges are lightly golden and the caramel is bubbling gently around the sides.

Avoid overbaking to keep the caramel soft and chewy.

Step 7: Cool and Chill

Allow the bars to cool completely in the baking pan.

Transfer the pan to the refrigerator and chill for at least 1–2 hours, or until the caramel has fully set.

Lift the bars from the pan using the parchment paper and cut into 16 squares.

Recipe Notes & Tips

• Line the Pan Well – Parchment paper makes removing the bars much easier.
• Use Good-Quality White Chocolate – It melts more smoothly and adds better flavor.
• Chill Before Cutting – Cold bars slice much more cleanly.
• Use a Warm Knife – Run your knife under hot water and wipe dry between cuts for perfect edges.
• Don’t Overbake – The caramel should remain soft and chewy after cooling.
• Store Chilled – Refrigeration keeps the caramel firm and the bars easy to handle.
