  • Totally customizable – make the mane pink and purple one day, blue and green the next!

Ingredients for Your Unicorn Cake

Gather these magical ingredients – trust me, the right components make all the difference between a basic cake and a showstopper unicorn creation:

  • Dry Ingredients:
    • 2 cups all-purpose flour (spooned & leveled)
    • 1 1/2 cups granulated sugar
    • 1 tbsp baking powder
    • 1/2 tsp fine salt
  • Wet Ingredients:
    • 1/2 cup unsalted butter (softened to room temp – not melted!)
    • 3 large eggs (room temp helps them incorporate better)
    • 1 cup whole milk
    • 1 tsp pure vanilla extract
  • For Decorating:
    • Gel food coloring (pink, blue, purple – Wilton or Americana work great)
    • 1 cup heavy whipping cream (chilled)
    • Edible gold dust or luster dust
    • White fondant (about 8 oz)
    • Gold fondant or yellow fondant plus edible gold paint

Ingredient Notes & Substitutions

Here’s the inside scoop on making your unicorn cake shine:

Gel vs liquid food coloring: Gel is my go-to because it gives vibrant colors without thinning the batter. If you only have liquid, use 3-4 drops max per color – too much will make your layers soggy.

Fondant alternatives: If fondant scares you, try molding the horn from candy melts or white chocolate. For ears, use stiff buttercream or even cut marshmallows at an angle!

Whipped cream vs buttercream: Whipped cream gives that dreamy cloud-like look, but if your cake needs to sit out longer, use stabilized whipped cream (add 1 tbsp instant pudding mix per cup) or American buttercream tinted pastel colors.

Equipment You’ll Need for the Unicorn Cake

Before we dive into the magic, let’s round up our unicorn-worthy tools – nothing fancy needed, just the basics with a few special extras:

  • Two 8-inch round cake pans (or one deep pan if you’re doing a single layer)
  • Mixing bowls (one large, two medium – you’ll need them for colored batters)
  • Hand mixer or stand mixer (your arms will thank you for this!)
  • Silicone spatula for scraping every last bit of that precious batter
  • Fondant roller and small knife (a clean plastic ruler works in a pinch for rolling)
  • Piping bag with star tip for that gorgeous whipped cream mane
  • Toothpicks (for swirling colors and testing doneness)

That’s it – no magic wands required, I promise!

If you’re in the mood for another dessert that feels just as indulgent, don’t miss these Basque cheesecake brownies. They’re rich, fudgy, and the perfect contrast to a light, playful cake.

How to Make a Unicorn Cake

Okay, let’s make some magic happen! This unicorn cake comes together in simple steps, but the colorful layers will make everyone think you’re a baking wizard. Here’s exactly how I do it:

  1. Prep your pans: Butter and flour two 8-inch round pans like your cake’s life depends on it (because it kinda does). Cut parchment circles for the bottoms – this guarantees those beautiful layers will release perfectly.
  2. Mix the dry team: Whisk together flour, sugar, baking powder and salt in your biggest bowl. I always sift mine – it makes the cake so light and airy you’ll swear it floats!
  3. Cream the butter & sugar: Beat the softened butter and sugar for a full 3 minutes until it’s pale and fluffy. Scrape the bowl! Now add eggs one at a time, then vanilla. The mixture should look like sunshine in a bowl.
  4. Alternate wet & dry: Add 1/3 of the flour mix, then half the milk. Repeat, ending with flour. Go slow – overmixing is the enemy of tender unicorn cake!
  5. Color your magic: Divide the batter evenly between three bowls. Add gel coloring – I do pink, blue and purple, about 1/4 tsp each. Stir gently until you get those dreamy pastel hues.
  6. Layer & bake: Dollop the colored batters randomly into pans – don’t stir! Just let them sit in pretty blobs. Bake at 350°F for 25-30 minutes until a toothpick comes out clean. Cool completely – rushing this step leads to frosting meltdowns!

Decorating Your Unicorn Cake

Now for the really fun part – bringing your unicorn to life! Here’s how I create that signature look:

First, make the horn and ears: Knead your white fondant until soft (if it’s sticky, dust with powdered sugar). For the horn, roll a cone shape and twist it gently. Paint with edible gold dust mixed with vodka (it dries quicker than water!). For ears, shape two small teardrops and flatten slightly. Pro tip: Chill these for 15 minutes before placing – they’ll hold their shape better.

Next, frost your cake: I use a thin crumb coat of whipped cream first, then go back with big swoopy dollops using a star tip to create that fluffy mane effect. Don’t stress about perfect piping – unicorns are whimsical creatures!

Finally, add the magic touches: Gently press your fondant pieces into place. Dust everything with edible glitter (I use a soft brush to tap it on). The finishing touch? Tiny sprinkles around the base for that enchanted fairy dust look!

Tips for the Perfect Unicorn Cake

After making dozens of these magical cakes, I’ve picked up some tricks that make all the difference:

  • The toothpick test is your best friend – insert it near the center. If it comes out with a few moist crumbs (not wet batter), you’re golden. Overbaking dries out those beautiful pastel layers!
  • Rotate your pan halfway through baking – oven hotspots can cause uneven coloring, and we want every slice to show off those rainbow swirls evenly.
  • Chill your cake before decorating – a 30-minute fridge session firms up the layers so your whipped cream frosting goes on smooth without pulling up crumbs.
  • Store leftovers in the fridge – whipped cream frosting means this beauty needs to stay chilled. Just bring to room temp for 15 minutes before serving for the best texture.

Trust me, these little tips will make your unicorn cake look like it came from a professional bakery!

Unicorn Cake Variations

The beauty of unicorn cake is how easily you can make it your own! Here are my favorite twists:

  • Rainbow explosion: Add extra food coloring divisions for six vibrant layers instead of three – kids go nuts when you slice into it!
  • Chocolate lovers: Swap 1/2 cup flour for cocoa powder in one batter division for a magical chocolate-pastel marbled effect.
  • Vegan magic: Use flax eggs, plant milk, and vegan butter – the colors still pop beautifully!

Really, any flavor works as long as you keep those dreamy colors and golden horn!

Serving and Storing Your Unicorn Cake

This magical cake deserves the perfect presentation! Let it sit at room temperature for 15 minutes before serving – that slight chill off takes the whipped cream from fridge-cold to heavenly light. For storage, pop it in an airtight container in the fridge. It’ll stay fresh and fabulous for 2-3 days (though let’s be real – it never lasts that long!). The fondant decorations might soften slightly, but the golden horn keeps its sparkle beautifully.

Unicorn Cake Nutrition Information

Let’s be real – we’re not eating unicorn cake for its health benefits! But if you’re curious, here’s the scoop on what’s in each magical slice (based on 8 servings):

  • Calories: About 350 per slice (worth every bite!)
  • Fat: 12g (most from that delicious butter)
  • Carbs: 55g (hey, it’s a celebration cake!)
  • Protein: 5g (eggs doing their part)
  • Sugar: 25g (it’s a unicorn – of course it’s sweet!)

Remember, nutritional values are estimates and will vary based on specific ingredients you use. For a lighter version, you can try swapping some sugar for monk fruit sweetener or using low-fat whipped topping. But honestly? Some days just call for full-on magical indulgence!

Unicorn Cake FAQs

I get asked these questions ALL the time – here are my tried-and-true answers to make your unicorn cake adventure smooth sailing:

Can I make this cake ahead?

Absolutely! Bake the layers up to 2 days in advance – just wrap them tightly in plastic wrap and freeze. Thaw at room temp before decorating. The fondant pieces can be made a week ahead and stored in an airtight container. Pro tip: Assemble the cake the day of serving for the freshest look!

How do I prevent colors from bleeding?

Gel food coloring is your secret weapon! The thick consistency means vibrant hues without extra liquid that could make layers run. Also, let each colored batter sit for 5 minutes before layering – this helps the colors “set.”

Can I use boxed mix?

You bet! Just prepare the batter as directed, then divide and color it. You’ll need about 1/4 tsp gel color per 1 cup of batter. The texture might be slightly lighter than homemade, but it’ll still look magical!
