Ingredient Highlights
Oreo cookies: A full layer of whole Oreos forms the base, with more chopped Oreos on top for extra crunch.
Sweetened condensed milk: Poured over the cookies for rich, sticky sweetness.
Whipped topping: Lightens the texture and creates a creamy layer between the cookies and cake.
Chocolate cake mix: Sprinkled dry over the top—it forms a soft, fudgy layer as it bakes.
Butter: Sliced and placed over the dry mix to help everything melt together.
Extra Oreos: Chopped and scattered over the top for that signature cookies-and-cream finish.
Pro Tips Before You Start
Don’t stir the layers! Just add each one and let the oven do the work.
Use full-fat condensed milk and real whipped topping for the richest texture.
Slice butter thinly and spread evenly so the top bakes through properly.
Want it extra gooey? Serve warm with ice cream right after baking.
Let it cool slightly if slicing clean squares is your goal.

Step 1: Preheat & Prep

Storage & Leftovers
Refrigerate: Store leftovers in an airtight container in the fridge for up to 4 days.

FAQs
Can I make this ahead of time?
Yes! Assemble and refrigerate unbaked for up to 24 hours, then bake when ready.
Can I use a different cake mix flavor?
Absolutely. Red velvet, devil’s food, or vanilla all work beautifully.
Do I need to stir the layers?
Nope—dump cakes work best when left untouched. Just layer and bake.
Can I use homemade whipped cream?
Yes, but be sure it’s stabilized or thick enough to hold up during baking.
What if I don’t have Oreos?
Try other cookies like Chips Ahoy, Nutter Butters, or graham crackers for a twist.
Why slice the butter instead of melting it?
Slicing allows even distribution as it melts and helps the cake mix cook through.
Can I double this recipe?
Definitely! Use two pans or a large sheet pan and extend the bake time slightly.
