Ingredients You’ll Need

• 24 Funfetti Oreos (or regular Oreos)
• 2 cups heavy whipping cream
• ¼ cup powdered sugar
• 1 teaspoon vanilla extract
• 1 package (8 oz) cream cheese, softened
• 1 cup Funfetti cake mix (dry)
• ½ cup whole milk
• ½ cup rainbow sprinkles (plus extra for topping)
• 1 cup mini marshmallows (optional)

Step-by-Step Instructions

1. Make the Whipped Cream:
   • In a chilled mixing bowl, whip the heavy cream, powdered sugar, and vanilla with an electric mixer until stiff peaks form. This forms the airy base of your filling. Set aside.
2. Prepare the Filling:
   • In a separate bowl, beat the cream cheese until completely smooth and lump-free.
   • Add the dry Funfetti cake mix and whole milk. Beat until the mixture is creamy and well combined.
   • Fold in half of the prepared whipped cream to lighten the mixture. Then gently fold in the remaining whipped cream until fully incorporated. You should have a light, fluffy, and slightly sweet cream filling.
3. Assemble the Layers:
   • In an 8x8-inch dish (or similar), arrange a layer of Funfetti Oreos to cover the bottom.
   • Spread about a third of the cream mixture over the cookies, smoothing it out with a spatula.
   • Repeat with another layer of cookies and cream, then a final layer of each, ending with cream.
   • Sprinkle the top with rainbow sprinkles, and add mini marshmallows for extra sweetness and fun texture.
4. Chill:
   • Cover the dish with plastic wrap and refrigerate for at least 4 hours, preferably overnight. This allows the Oreos to soften and meld with the cream filling, creating a cake-like texture.
5. Serve:
   • Remove from the fridge and slice into squares. Garnish with more sprinkles or a swirl of whipped cream for extra flair. Serve chilled and enjoy every gooey, creamy bite.

Serving and Storage Tips

• Serve chilled: This dessert is best served cold straight from the fridge.
• Store leftovers: Keep tightly covered in the refrigerator for up to 5 days.
• Make-ahead bonus: Assembles beautifully the day before your event.
• Freezing tip: Freeze for 1 hour before serving for firmer, ice cream cake-like texture.
• Creative presentation: Try individual servings in mason jars or clear cups for parties.

Helpful Notes

• Cookie swap: Use Golden Oreos, chocolate chip cookies, or graham crackers for different flavor profiles.
• Flavor boost: Add a dash of almond extract or lemon zest to the filling for a twist.
• Colorful variation: Mix food coloring into the whipped cream or use different sprinkle themes.
• Diet tweaks: Use reduced-fat cream cheese or coconut whipped cream for lighter versions.
• Extra crunch: Add crushed candy or cookie crumbles on top for texture contrast.
