- Funfetti cake mix: This is the star because it brings the cake-like texture and those colorful sprinkles baked right in.

- Salted butter (melted for bars, room temp for frosting): Butter adds richness—the salt balances the sweetness beautifully.
- Heavy cream: Keeps the bars moist and creates that luscious frosting texture.
- Cream cheese: The creamy base of the frosting—make sure it’s softened to avoid lumps.
- Powdered sugar: Sweetens and thickens the frosting perfectly.
- Vanilla extract: Adds warmth and depth to the frosting’s flavor.
- Purple and blue food coloring: For creating those magical unicorn swirls in the frosting.

How to Make Funfetti Cake Mix Unicorn Bars Recipe
Step 1: Mix Your Bar Batter
Start by whisking together the funfetti cake mix, one large egg, melted butter, and heavy cream in a bowl until smooth and well combined. The batter will be a bit thicker than typical cake batter—that’s perfect for bars. No lumps here! Be careful not to overmix to keep them tender.
Step 2: Bake It Just Right
Pour that gorgeous batter into a greased 9×9-inch pan, smoothing it out evenly. Pop it into your preheated oven at 350°F (175°C) for about 20–25 minutes. Keep an eye on them starting at 20 minutes—when the edges look set and a toothpick inserted near the center comes out mostly clean with a few moist crumbs, they’re ready. Remember, you want chewy, moist bars, not dry and cakey.
Step 3: Whip Up the Unicorn Frosting
While your bars cool, make the frosting by beating together the softened cream cheese and butter until silky smooth. Gradually add the powdered sugar, a cup at a time, mixing well as you go. Stir in vanilla extract and just enough heavy cream to reach a fluffy, spreadable consistency. Don’t rush this step—patience makes a dreamy frosting.
Step 4: Get Your Swirl On
Divide your frosting into two small bowls. Tint one with purple food coloring and the other with blue until you achieve that perfect pastel unicorn vibe. Then, dollop spoonfuls of each color randomly over the cooled bars. Use a butter knife or skewer to gently swirl the colors together, creating that whimsical marbled look. Don’t over-swirl or you’ll lose the color pops!
Step 5: Sprinkle the Magic
For that final magical touch, scatter your favorite rainbow or unicorn-themed sprinkles right on top. These add texture, sparkle, and enormous charm. Pop your bars in the fridge for 30 minutes to let the frosting set so your swirls stay beautifully defined when you cut.
How to Serve Funfetti Cake Mix Unicorn Bars Recipe

Garnishes
I usually keep it simple and just go with a generous sprinkle of colorful confetti sprinkles because they add that whimsical flair that matches the frosting perfectly. Sometimes I like to add edible glitter or a few little star-shaped sugar decorations if it’s for a special occasion. They make the bars look party-ready in no time.
Side Dishes
These bars are fantastic on their own, but if I’m serving them at a brunch or dessert spread, I love pairing them with fresh berries or a light whipped cream. A scoop of vanilla bean ice cream on the side also works beautifully for an indulgent treat that melts into the swirled frosting.
Creative Ways to Present
For birthdays or unicorn-themed parties, I like to cut the bars into fun shapes using cookie cutters—hearts, stars, or even mini unicorns if you’ve got the right cutter. Placing them on a nice platter with a few pastel-colored napkins and some fun paper straws nearby just elevates the whole vibe. Kids and adults alike love how playful the presentation feels!
Make Ahead and Storage
Storing Leftovers
I always keep leftover Funfetti Cake Mix Unicorn Bars Recipe chilled in an airtight container in the fridge. This keeps the frosting firm and the bars moist. They usually last up to 4 days like this — but fair warning, they rarely stick around that long in my house!
Freezing
Freezing works really well if you want to prep in advance. I wrap individual bars tightly in plastic wrap and then store them in a freezer bag. They keep beautifully for up to 3 months. When you want to enjoy, just thaw in the fridge overnight and you’re good to go!
Reheating
If you like your bars slightly warm, I suggest reheating briefly in the microwave for about 10 seconds. This loosens the frosting a bit without melting it entirely and revives that soft, buttery texture. Just be careful not to overdo it—you want warm but still able to hold their pretty unicorn swirl!
FAQs
-
Can I make Funfetti Cake Mix Unicorn Bars Recipe without cream cheese frosting?
Absolutely! While the cream cheese frosting adds that creamy tang and richness, you could swap it out for a simple vanilla buttercream or even a thick glaze made from powdered sugar and milk. However, the cream cheese frosting really complements the bars’ flavor and keeps everything balanced.
-
Can I use regular cake mix instead of funfetti?
You can, but you’ll miss out on those iconic rainbow sprinkles baked into the bars that make this recipe so special. If you want to go that route, consider stirring in your own sprinkles into the batter after mixing for a similar look and feel.
-
How do I prevent the frosting colors from blending too much when swirling?
The trick is to use a light hand when swirling. Dollop the colored frostings separately and drag a knife or skewer through slowly and gently—think of it as painting delicate waves. Over-swisting can muddy the colors.
-
Can I make these bars ahead of time for a party?
Definitely! These bars actually taste great when made a day ahead since the flavors meld nicely. Just keep them refrigerated and add sprinkles right before serving if you want them extra fresh.
-
What’s the best pan size for this recipe?
A 9×9-inch square pan works perfectly here, giving you bars with just the right thickness—not too thin and not too cakey. Using a pan significantly larger or smaller will affect baking time and texture.
Final Thoughts
If you’re craving a no-fuss dessert that feels like a celebration every time, the Funfetti Cake Mix Unicorn Bars Recipe should be your go-to. I can’t tell you how many times I’ve been asked for the recipe after sharing these with friends—they’re that irresistible. So go ahead, gather your ingredients, and make yourself a batch.
