Okay, now let’s address this unicorn cake. Not the mythical creatures you’ll never meet, but the ones that show up in the most unexpected places: like on cakes. Yup, you’ve likely come across those unicorn cake on IG and those colorful cakes with icing spirals and some sort of fairy-dust sheen to them. But if you haven’t attempted one yet, believe me, you are denying yourself loads of joy in the process of baking. However, before you rush to saying, “Well I’m not even a professional baker,” relax! Guys, this unicorn cake is easier than it looks and is amazing for any occasion – birthday, baby shower or just for the fun of being a unicorn for a day, right? Alright, put your apron on and let me tell you all about how you can bake a cake as amazing as this one here and cool your grandma’s heels!

What is a Unicorn Cake?

Okay, so what makes a unicorn cake different from your average birthday cake? It’s all about the whimsy! The unicorn cake is usually decorated with bright pastel colors, loads of fun swirls, and of course, some kind of magical unicorn horn or ears to make it truly stand out. It’s a cake that’s as much about looking cool as it is about tasting delicious.

It’s kind of like the cake world’s version of a rainbow, with frosting in every color of the spectrum and sprinkles of joy (literally). Think of it as a party in cake form. This cake isn’t just a treat for the taste buds—it’s a visual feast that screams fun, creativity, and magic.

Why is Unicorn Cake So Popular?

Unicorns are the trending thing right now. Seriously, they’re everywhere. From unicorn lattes to unicorn-themed pajamas, the magic of these mythical creatures has taken over pop culture in the best way possible. And why wouldn’t it? It’s a fun, positive, and colorful creation and who wouldn’t love these three aspects at any party? But still the unicorn cake does not get attention because it is a trend only. It is also a good time to come up with something unique when baking. The rainbow frosting, the adorable horn, the sparkles, it’s a fun idea, but it’s also quick to pull off with edible glitter and sprinkles along with a few tips on how to frost a horn. If you’re like me, there’s something satisfying about taking a regular cake and turning it into a showstopper. And who doesn’t want to make their friends (and maybe even a few strangers) do a double-take?

What You’ll Need to Make the Unicorn Cake

Before we start talking cake science, let’s round up everything you’ll need for the best unicorn cake experience. (I promise it’s not as overwhelming as it seems!)

For the Cake:

• Cake Mix: Honestly, you can’t go wrong with a boxed cake mix here. You don’t need to be a cake expert to pull this off. Just choose your favorite flavor—vanilla, chocolate, or even strawberry if you’re feeling fancy.
• Eggs, Butter, and Milk: Check the instructions on your cake mix, but you’ll typically need eggs, butter (or oil), and milk.
• Food Coloring: This is where the magic happens. Grab some gel food coloring to create your rainbow. I recommend gel because it won’t water down your batter like liquid coloring can.

the Frosting:

• Butter: You’ll need plenty of butter for a smooth, creamy frosting.
• Powdered Sugar: This is what makes your frosting sweet and fluffy.
• Vanilla Extract: For that rich, vanilla flavor.
• Heavy Cream: A little cream will help your frosting reach that perfect consistency.
• Food Coloring: Same as the cake batter—go for gel for vivid, vibrant colors.

For Decoration:

• Unicorn Horn: You can either make one with fondant or use a pre-made one from a baking store. Or, get creative with a cone (like an ice cream cone) and decorate it.
• Unicorn Ears: You can easily make these from fondant or white chocolate. Super simple, and they add that extra cute factor.
• Edible Glitter/Sprinkles: This is the fun part! Go wild with edible glitter or rainbow sprinkles to make it truly magical.

Tools:

• Cake Pans: Two round cake pans (8-inch works well, but you can go larger or smaller depending on your preference).
• Piping Bags: For all those beautiful frosting swirls.
• Spatula: For smoothing out the frosting.
• Cake Turntable (optional): This isn’t necessary, but it can make decorating so much easier, especially when you’re working with multiple colors of frosting.

How to Make a Unicorn Cake (Step-by-Step)

Alright, now that we’ve got our ingredients together, let’s jump into the cake-making process. I promise you, it’s way easier than you think.

1. Bake the Cake

Start by preheating your oven to the temperature listed on the cake mix box. While the oven is warming up, prepare your cake pans by greasing them with butter or non-stick spray. Then, follow the instructions on the cake mix box—usually, this involves mixing the cake mix with eggs, butter, and milk.

Once your batter is ready, divide it evenly into separate bowls (usually about 4-5 bowls, depending on how many colors you want for your rainbow). Add a few drops of food coloring to each bowl, and mix until you get the desired shades. I like to go with a classic pastel rainbow: pink, blue, purple, yellow, and green.

Pour each color into your prepared cake pans, one layer at a time. Don’t worry if it’s not perfect; you’re going for a swirled, dreamy look. Once all your colors are in, use a butter knife or skewer to swirl the batter around a little. Don’t overdo it—you still want to see those color streaks.

Bake the cakes according to the package directions. Once they’re done, let them cool completely. Trust me, you don’t want to frost a warm cake—it’ll make the frosting melt all over the place.

2. Make the Frosting

While your cake is cooling, make the frosting. In a large bowl, beat together the butter and powdered sugar. Once that’s smooth, add in the vanilla extract and heavy cream. Keep mixing until it’s light and fluffy—like clouds! (Okay, I know, it’s cheesy, but that’s what we’re going for, right?)

Divide the frosting into separate bowls, just like you did with the batter. Add your food coloring and mix until you’ve got your rainbow of frostings ready to go.

3. Assemble the Cake

Now comes the fun part—stacking and frosting! Place your first layer of cake on a cake stand or plate. Spread a thin layer of frosting over the top, and then carefully place your second layer on top. Make sure everything is even so that your unicorn cake stands tall and proud.

Next, cover the whole cake with a thin layer of frosting—this is called the crumb coat, and it helps seal in all those crumbs so they don’t mess up your final layer of frosting. Pop the cake in the fridge for 20 minutes to set the crumb coat.

Once that’s done, it’s time for the real frosting magic. Take your piping bags (if you’ve got them) and fill each one with a different color of frosting. Use a large round piping tip to pipe big, colorful swirls all around the top and sides of the cake. Don’t worry about being perfect—this cake is all about having fun and playing with color.

4. Decorate with Unicorn Ears and Horn

Now, grab your unicorn ears and horn! If you’re using fondant, shape the ears into little triangles and add some detail to them (think pink or gold for the inner ear). Place the ears on top of the cake, near the edges.

For the horn, if you’re using an ice cream cone, cover it in gold edible glitter or yellow frosting to make it sparkle. Stick the cone right in the center of the cake. The horn should be tall enough to stand out but not too long that it tips over the cake.

5. Add the Finishing Touches

Here’s where you can go wild—add as much edible glitter, rainbow sprinkles, or confetti as you want. If you’ve got some extra frosting, pipe a few small rosettes on the top or around the base. This part is your chance to go overboard with the magic!

Tips for a Perfect Unicorn Cake

• Don’t Rush the Frosting: If you’ve never worked with colored frosting before, take your time. You want those swirls to look beautiful, so be patient.
• Make It Ahead of Time: You can bake the cakes and make the frosting a day or two before you need the cake. Just wrap the cooled cakes in plastic wrap and store them in the fridge until you’re ready to frost.
• Get Creative with Colors: Unicorn cakes don’t have to stick to the standard rainbow colors. Go for your favorite pastels, or even try metallics for a modern twist!
• Have Fun with the Details: This is a cake that thrives on creativity. Don’t be afraid to add extra fun elements, like edible flowers, rainbow candy, or sparkly dust.

The Final Verdict: Is It Worth It?

100% yes! If you’re looking for a cake that’s both delicious and totally Instagram-worthy, a unicorn cake is the way to go. It’s colorful, it’s fun, and it’s a total crowd-pleaser. Plus, you can
