Ingredients for No-Bake Funfetti Oreo Icebox Cake

Think of this as a playful mash-up of cookies, fluffy filling, and sprinkles. You only need a handful of grocery store staples and a little patience while it chills.

• 36 to 40 Oreo cookies. Golden or Birthday Cake Oreos are perfect for that vanilla party vibe.
• 1 and 1/2 cups cold milk for dipping the cookies. Whole or 2 percent works well.
• 8 ounces cream cheese, softened. Room temp blends smoother.
• 1 teaspoon vanilla extract.
• 1 cup powdered sugar.
• 2 cups heavy cream or 16 ounces whipped topping. Use what you like.
• 1 box instant vanilla pudding mix, 3.4 ounces. Optional but adds body.
• 1/3 to 1/2 cup rainbow sprinkles. Use jimmies for less color bleed.
• Pinch of salt to balance sweetness.
• Extra Oreos and sprinkles for topping, optional but festive.

Pro tip: Heavy cream whipped to soft peaks feels rich and homemade. Whipped topping is lighter and easier. Both work great.

Step-by-Step Instructions for Making the Cake

This is a chill-and-layer situation. No oven. No fuss. Here’s exactly how I build it for neat slices and great texture.

1. Chill your mixing bowl and beaters for a few minutes. Cold tools whip cream faster.
2. Whip the heavy cream to soft peaks. Set aside. If using whipped topping, skip this step.
3. In a separate bowl, beat the cream cheese until smooth. Add powdered sugar, vanilla, and a pinch of salt. Blend until creamy and no lumps remain.
4. If using pudding mix, sprinkle it into the cream cheese mixture and mix until combined. It thickens the filling and helps the cake slice cleanly.
5. Fold the whipped cream or whipped topping into the cream cheese mixture. Do this gently so the mixture stays fluffy.
6. Sprinkle in the rainbow sprinkles and fold once or twice. Don’t overmix or the colors may streak.
7. Pour the milk into a shallow dish. Quickly dunk each Oreo, 1 to 2 seconds per side. You want them softened but not soggy.
8. Line the bottom of an 8 by 8 or 9 by 9 dish with a single layer of dipped Oreos.
9. Spread a third of the funfetti filling over the cookies. Repeat with cookies and filling to make 3 layers of each. End with filling on top.
10. Decorate with crushed Oreos and more sprinkles.
11. Cover and chill at least 6 hours. Overnight is best for a classic icebox texture.

Make-Ahead Game Plan

Build the cake the night before. Chill overnight. Slice just before serving for the cleanest squares. It holds beautifully and tastes even better the next day.

Tips for Perfecting Your Icebox Cake

Softening the cookies: Keep the dunk quick. If your cookies are super fresh and crisp, count a slow one-two in the milk. If your Oreos are a bit older, skip the count and just dip fast.

The filling: Cream cheese needs to be soft. Let it sit on the counter 30 minutes so you don’t get tiny lumps. Lumps disappear less once you fold in the cream.

Thickness matters: If your filling feels too loose, add the pudding mix or chill the filling 10 minutes before layering. It should spread easily but hold soft peaks.

Sprinkles: Use jimmies, not nonpareils. Jimmies bleed less, so your filling stays more pastel than tie-dye.

Neat slices: Clean your knife between cuts. Wipe and dip the knife in hot water, then dry and slice again for crisp edges.

Variations and Customizations for Funfetti Oreo Cake

Once you nail the basics, feel free to play. The format is simple. Cookies, filling, chill. The rest is your personality.

Flavor Twists

Chocolate dream: Use classic chocolate Oreos and add 2 tablespoons unsweetened cocoa to the filling. Keep the sprinkles for contrast.

Berry shout-out: Add a thin stripe of strawberry or raspberry jam between layers for a sweet-tart surprise.

Lemon sunshine: Swap in lemon Oreos and fold a teaspoon of lemon zest into the filling. Sprinkles still look great on yellow.

Tropical spin: For a sunny vibe, check out this breezy no-bake pineapple heaven cheesecake dessert and borrow the pineapple garnish idea on top of the cake.

Diet-Friendly Swaps

Lighter option: Use Neufchâtel cheese and light whipped topping. Choose reduced-fat milk and a smaller sprinkle count. Flavor stays bold.

Gluten friendly: Look for gluten-free sandwich cookies. The rest of the ingredients are easy to adapt.

Lower sugar: Reduce powdered sugar to taste and skip the pudding mix. It will be softer but still lovely.

Storage and Serving Suggestions

Chill the finished cake at least 6 hours. Overnight is best. The cookies soften into a cake-like bite and the filling sets into a creamy cloud. Cover tightly to keep the edges from drying out.

In the fridge, this cake holds up well for 3 days. The sprinkles stay colorful. After day three, it still tastes good, but the cookie layers may soften more.

For freezing, assemble without the sprinkle topping, wrap well, and freeze up to 1 month. Thaw in the fridge overnight, then add sprinkles before serving for a fresh look.

Serve cold with a cup of coffee or a scoop of vanilla ice cream. If you have snack trays going, tuck in a few no-bake peanut butter cheesecake balls for a fun mix-and-match dessert moment.

Cutting tip. Use a warm, dry knife and pull out the first piece with a thin spatula. The second piece comes out like a dream.

Common Questions

How long does the No-Bake Funfetti Oreo Icebox Cake need to chill?
At least 6 hours, but overnight gives you the neatest slices and best texture.

Can I skip the pudding mix?
Yes. The filling will be a touch looser, but it still sets nicely. Chill a bit longer and keep the layers thick.

What if my sprinkles bleed?
Use jimmies and fold them in at the end. If you see streaks, stop mixing. The color will even out as it chills.

Can I use Cool Whip instead of heavy cream?
Totally. It keeps the cake light and fluffy. If you want a richer filling, go with whipped heavy cream.

What size pan works best?
An 8 by 8 or 9 by 9 works well. A loaf pan creates thicker layers and tall slices. A 9 by 13 gives a thinner cake and feeds a crowd.
