No-Bake Funfetti Oreo Cake

No-bake Funfetti Oreo Icebox Cake might be the simplest showstopper dessert you will ever make and it never fails to spark smiles. The sweet nostalgia of Funfetti with creamy layers and Oreo cookies all meld together in the fridge for a cake that feels festive but takes truly minimal effort. It is perfect when you want a crowd-pleaser or need a make-ahead treat for birthdays and casual parties.

I first put this together one summer when the power went out and baking was off the table. Even my most skeptical taste-tester asked for seconds and now my family requests it for every fun occasion.

Ingredients

• Heavy cream: brings the fluff to the filling and ensures every layer is silky and rich
• Powdered sugar: sweetens without any grittiness and melts perfectly for a smooth texture
• Vanilla extract: adds a warm background note and brings out all the flavors
• Oreo cookies: deliver a chocolatey base with a touch of salt to balance the sweetness. Choose classic Oreos for the best texture
• Sprinkles: dial up the fun and color with every slice. Use pastel or rainbow nonpareil style for the brightest result
• Cream cheese: gives structure and tang that keeps the filling from being too sweet. Look for full-fat bricks at room temp for the creamiest blend
• Funfetti cake mix: infuses the cream with cake batter flavor and flecks of color throughout. Use a fresh box for best flavor
• Milk: loosens the mix and helps everything whip up light and spreadable. Any kind will work but whole milk is richest

Instructions

Whip the Cream:

In a large chilled bowl whip the heavy cream powdered sugar and vanilla using a hand mixer or stand mixer. Beat on medium high until stiff peaks form which means the cream will hold its shape when you lift the blades. Scrape the whipped cream into a separate bowl and chill if your kitchen is warm

Blend the Filling:

In another clean bowl beat the cream cheese until there are no lumps and it is completely smooth. Add the Funfetti cake mix and pour in the milk and continue mixing until all the dry mix disappears and the texture is light and airy. Be sure the cream cheese is totally soft or you will get lumps

Combine Fillings:

Gently fold one third of the whipped cream into the cream cheese mixture using a rubber spatula. Fold until just combined then add the rest of the cream in two batches. This keeps your filling light so it does not deflate

Prepare Your Pan:

Spread a thin even layer of the cream filling over the bottom of a nine by thirteen inch dish. This anchors your cookies and makes for easy serving later

Layer the Cookies and Cream:

Place a single layer of Oreo cookies over the base with edges touching but not overlapping. Cover the cookies with a third of the remaining filling using an offset spatula or the back of a spoon to smooth it. Repeat another layer of Oreos and then cream until you have used all the cookies and end with a generous topping of the cream mixture

Add Sprinkles and Chill:

Scatter sprinkles liberally over the top of the cake pressing a few down gently so they stay put. Cover the entire dish tightly with plastic wrap. Refrigerate at least four hours or overnight so the cookies soften and everything melds into sliceable cake

My favorite part is sneaking a few extra sprinkles into the filling so you get that fun confetti look all the way through. I will never forget my niece’s face the first time she saw this dessert in the fridge she just gasped and clapped her hands and I knew I had a new family classic.

Storage Tips

Cover your cake tightly with plastic wrap or a fitted lid and refrigerate. It will stay creamy and delicious for up to four days. For longer storage freeze slices on a lined tray then wrap in plastic for grab and go desserts. Thaw overnight in the fridge.

Ingredient Substitutions

Swap the Oreos for Golden Oreos or graham crackers for a twist. If you want to make it gluten free use gluten free sandwich cookies and certified gluten free cake mix. The Funfetti mix can be replaced with any white or yellow cake mix plus an extra handful of sprinkles.

Serving Suggestions

Serve this cake super chilled and sliced in generous squares. Top each piece with a dollop of extra whipped cream and more sprinkles if you are feeling festive. It is perfect for birthday parties summer cookouts or as a whimsical surprise at brunch.

Cultural and Historical Context

Icebox cakes first became popular in the early days of home refrigeration when cakes that did not need baking were a novelty. The Funfetti twist adds a modern nostalgic feel that hits with birthday party joy both for kids and grownups. Combining Oreos and Funfetti is a shortcut to maximum retro celebration.

Seasonal Adaptations

Add crushed freeze dried berries to the filling for a fruity pop Use holiday colored sprinkles for themed celebrations Mix in chopped nuts for a bit of crunchy contrast

Success Stories

One reader shared that she made this for a last minute playdate and it was the first dessert gone. Another served it as the only birthday cake at her son’s fifth birthday and every kid asked for seconds. Parents love it because it can be made by children with just a little help.

Freezer Meal Conversion

Assemble the cake completely even add the sprinkles then double wrap the dish tightly in plastic and foil. Freeze up to one month. Thaw overnight in the fridge and add fresh sprinkles if you like before serving. Texture is just as creamy as the day you made it.

This is one no-bake cake you will revisit every time there is something worth celebrating. No matter how many times you make it the colors and creamy texture never fail to impress.
