First, it’s impossible to mess up.

Forget measuring flour or creaming butter—just layer ingredients and walk away. Second, it’s ridiculously fast. Prep takes 5 minutes; the oven does the rest.

Third, it’s customizable. Swap Oreos for another cookie, add peanut butter, or throw in chocolate chips. Finally, it’s crowd-pleasing.

Who says no to Oreos baked into a warm, melty cake? Exactly.

Ingredients

  • 1 (15.25 oz) package Oreos (or store-brand—we won’t judge)
  • 1 box chocolate cake mix (or vanilla for contrast)
  • 1/2 cup (1 stick) unsalted butter, melted
  • 1 1/2 cups milk (whole or 2% for extra richness)
  • 1 cup mini marshmallows (optional, but highly recommended)
  • Vanilla ice cream (for serving, because duh)

Step-by-Step Instructions

  1. Preheat your oven to 350°F (175°C). Grease a 9×13-inch baking dish lightly.
  2. Layer the Oreos.

    Place whole Oreos evenly across the bottom of the dish. Crush a few for texture if you’re feeling fancy.


  3. Add the cake mix. Sprinkle the dry cake mix evenly over the Oreos.

    No stirring—this isn’t a chemistry lab.


  4. Drizzle the wet stuff. Pour melted butter and milk over the cake mix. Again, no mixing.

    Let it pool like a decadent swamp.


  5. Optional marshmallows. Scatter mini marshmallows on top for a gooey, s’mores-like twist.
  6. Bake for 25–30 minutes until the top is golden and the edges bubble. Your kitchen will smell like a bakery owned by Willy Wonka.
  7. Serve warm with ice cream.

    Watch it disappear faster than your motivation to meal prep.


Storage Instructions

Store leftovers (ha!) in an airtight container at room temp for 2 days or refrigerate for up to 5 days. Reheat in the microwave for 20 seconds to revive the gooeyness. Freezing?

Wrap slices tightly—they’ll last 3 months, but let’s be real, they won’t survive the week.

It’s fast, foolproof, and requires zero skill. Need dessert for a party? Done.

Kids begging for sweets? Solved. Craving chocolate at midnight?

Sorted. Plus, it’s budget-friendly—store-brand ingredients work just fine. And if you’re into minimal cleanup, the single baking dish is your new best friend.

Common Mistakes to Avoid

  • Overbaking.

    The cake should be fudgy, not dry. Set a timer.


  • Stirring the layers. The magic happens when you leave it alone.

    Trust the process.


  • Skipping the ice cream. This isn’t a drill—serve it warm with a scoop.
  • Using cold butter. Melt it first, or you’ll get weird clumps.

    Science.

Bored of Oreos? Try:

  • Peanut butter cups instead of Oreos for a Reese’s vibe.
  • Golden Oreos with vanilla cake mix for a lighter twist.
  • Add caramel sauce between layers for extra ooze.
  • Swap marshmallows for chocolate chips or nuts. Or both—live dangerously.

FAQ

Can I use a different cake mix?

Absolutely.

Vanilla, devil’s food, or even funfetti work. IMO, chocolate-on-chocolate is peak indulgence.

Why is my cake soggy?

You might’ve drowned it in butter or milk. Stick to the measurements—it’s a dump cake, not a swimming pool.

Can I make this ahead of time?

Yes, but bake it fresh for the best texture.

Prep the layers in the dish, cover, and refrigerate for up to 24 hours before baking.

Is this gluten-free?

Not as written, but use GF Oreos and cake mix, and you’re golden. FYI, gluten-free Oreos taste suspiciously like the real thing.
