Equipment

  • 1 9×13-inch baking dish Lightly greased
  • 1 Mixing Bowl For crushed Oreos
  • 1 Rolling Pin or Food Processor To crush cookies
  • 1 Small Saucepan or Microwave Bowl To melt butter
  • 1 Spatula For spreading topping

Ingredients

  • 24 cookies Oreo cookies Crushed into crumbs reserve some for topping
  • 1 box Chocolate fudge cake mix Dry, do NOT prepare
  • 1 can Sweetened condensed milk 14 oz
  • ½ cup Unsalted butter Melted
  • 1 container Whipped topping, Cool Whip Thawed, 8 oz

Instructions

  • Preheat your oven to 350°F (175°C) and lightly grease your baking dish. This is my favorite job to give my daughter Olivia, she loves pushing the oven buttons like she’s starting a rocket ship.
  • Place the [Oreo cookies] in a bag and crush them into crumbs using a rolling pin. Little hands LOVE this step, it’s noisy, messy, and very fun.
  • Spread the crushed [Oreos] evenly in the baking dish and gently press them down to form the base. Olivia calls this “the cookie floor.”
  • Sprinkle the dry [chocolate cake mix] evenly over the Oreo crumbs. No mixing, this is what makes a dump cake magical.
  • Slowly pour the [sweetened condensed milk] over the cake mix. This is what gives the cake that gooey center we all fight over.
  • Drizzle the melted [butter] evenly over the top so everything bakes into a golden, chocolatey dream.
  • Bake for 30–35 minutes until the top looks set and the edges are bubbling. Olivia always presses her nose to the oven door when the chocolate smell starts.
  • Let the cake cool for 10 minutes, then spread the [whipped topping] over the warm cake and sprinkle reserved Oreo crumbs on top.

Notes

  • This Oreo Dump Cake is best served warm with vanilla ice cream.
  • Store leftovers in the fridge for up to 3 days.
  • Swap in Golden Oreos for a vanilla twist.
  • Add chocolate chips or peanut butter drizzle for a fun upgrade.
  • This is my go-to dessert when Olivia’s friends come over, it never fails.
