How to Make This Unicorn Cake Recipe (Without Losing Your Sparkle)
Step-by-Step Directions for the Cake
Step 1: Prep like a pro
Start by preheating your oven to 350°F (175°C). Prepare three round cake pans, each measuring 8 inches in diameter, by thoroughly coating them with a layer of butter or non-stick spray to prevent sticking. Then, carefully place a sheet of parchment paper at the bottom of each pan, ensuring a smooth and even surface to facilitate easy removal of the baked cake layers. You want your unicorn cake layers to pop right out — no sticking allowed.
Step 2: Cream it real good
In a large mixing bowl, beat the unsalted butter until smooth and fluffy — about 3–5 minutes. Add the granulated sugar gradually, and keep beating until the mixture looks light and airy, almost like soft clouds. This step is where the magic starts.
Step 3: Add the eggs (one at a time, please)
Gently break each egg individually into the mixing bowl, ensuring that you incorporate them one at a time. After adding each egg, thoroughly blend it into the batter until the mixture becomes smooth and uniform before proceeding with the next. Don’t rush this — it helps the batter stay smooth and well combined.
Step 4: Vanilla swirl
Mix in the vanilla extract. Go for the real stuff — trust me, it makes a difference in flavor.
Step 5: Dry meets wet
Using a different mixing bowl, carefully combine the cake flour, baking powder, and salt by stirring them together with a whisk, ensuring that all the dry ingredients are evenly distributed and aerated for a lighter texture in the final baked product. Gradually add the dry mixture to the wet mixture, alternating with the milk (start and end with dry). Mix until just combined. No overmixing — we want tender, dreamy layers, not chewy bread.
Step 6: Divide and conquer
Evenly pour the batter into your prepared pans. Use a kitchen scale if you want perfect layers — or just eyeball it if you’re more of a “close enough” baker. Place the prepared batter into the preheated oven and allow it to bake for approximately 30 to 35 minutes, keeping a close eye on it as it reaches the final stages of baking. To determine if it is fully cooked, carefully insert a toothpick into the center; if it emerges without any wet batter clinging to it, the cake is ready to be removed from the oven. Cool the cakes completely before frosting (trust me on this — warm cake and frosting = slippy mess).
Buttercream Icing: Smooth and Sweet
Step 7: Make your buttercream base
To whip up the icing that will hold your unicorn cake together (literally and emotionally), beat unsalted butter until smooth. Gradually add powdered sugar and keep beating until fluffy.
Step 8: Vanilla + milk = magic
Add in the vanilla extract and a bit of whole milk. Mix until the texture is creamy and spreadable — not runny, not stiff. Just right.
Step 9: Ice it like a pro
Once the cakes are cool, level the tops if needed (a serrated knife works great). Stack the layers with buttercream in between. Then cover the whole cake in a smooth layer of frosting. Chill for 15–30 minutes to firm it up before decorating.

Step 10: Make the color swirl frosting
Now comes the fun part. Beat together the second batch of buttercream for decorating. Once it’s smooth, divide it into separate bowls and tint each one with your choice of food coloring — purple, pink, dark purple, blue, and black are the go-to shades for that classic unicorn cake recipe glow.
Step 11: Grab your piping bags
Load your colorful buttercreams into piping bags fitted with star and round tips (or whatever you’ve got — no need to buy fancy stuff if you’re working with basics).
Step 12: Add the flair
Pipe swirls, rosettes, and stars across the top and sides of the cake. Go wild or keep it simple — your kitchen, your rules. Add sprinkles, edible glitter, or even a gold unicorn horn if you’re feeling extra magical.
If fruity flavors are more your thing, or you’re baking for a strawberry-obsessed kiddo, try our dreamy vanilla cake with strawberry filling—it’s just as magical.
Tips for Nailing Your Unicorn Cake Recipe
- Soft butter = happy baker. Cold butter just won’t cream right. Let it sit out until you can press a finger into it easily.
- Sift your powdered sugar. I know it sounds fussy, but it keeps your frosting lump-free and ultra smooth.
- Use gel food coloring. It gives vibrant color without watering down your buttercream. Liquid coloring can thin the frosting too much.
- Chill the cake before decorating. A quick chill firms up the buttercream and gives you a clean canvas to work on.
- No piping bags? No problem. Snip the corner off a zip-top bag and call it a day. It works in a pinch and saves cleanup time.
And if your swirls aren’t symmetrical? That’s not a fail — it’s character. Remember: even unicorns aren’t perfect, and neither is frosting.
Real Talk: My First Unicorn Cake
I’ll admit it — the first time I attempted a unicorn cake, it looked more like a pastel-colored volcano than a magical creature. My kids didn’t care, though. They squealed with joy and asked if we could make it every weekend.
That cake (wobbly swirls and all) became a sweet little milestone in my kitchen journey — not because it was picture-perfect, but because it made everyone smile. And after a year of trying to balance work, virtual school, and keeping my sourdough starter alive (RIP), that felt like a win.
Since then, the unicorn cake recipe has become a go-to in our house. Birthdays, sleepovers, or just a “let’s bake something fun” kind of Saturday — it always hits the mark.
FAQsCan I make this unicorn cake recipe ahead of time?
Absolutely! It is possible to prepare and bake the individual cake layers ahead of time, allowing them to be made up to forty-eight hours before they are needed.
Once fully cooled, they should be properly wrapped and stored in an airtight container to maintain their freshness until you are ready to assemble and serve the final dessert.
Just wrap them tightly in plastic wrap and store them at room temperature. The frosting can be made a day ahead, too — just keep it refrigerated and let it soften before using.
How can I store leftovers?
Leftovers (if there are any!) can be stored in an airtight container at room temperature for up to two days or in the fridge for five days. Just make sure to bring the cake to room temp before serving — nobody likes a cold unicorn!
Can I freeze the cake?
Yes! Freeze the unfrosted cake layers wrapped in plastic and foil for up to two months. For a frosted unicorn cake, freeze it uncovered for an hour to set the frosting, then wrap and store. Thaw in the fridge overnight before serving.
Can I use natural food coloring?
You sure can! Just keep in mind that the colors may be a bit more muted. But hey, even pastel unicorns are magical.
There’s something undeniably joyful about creating a unicorn cake — the colors, the swirls, the pure whimsy of it all. It’s more than just a dessert; it’s a celebration in layers.
