Tools Needed to Make a Unicorn Cake

Having the right tools makes the process smooth and enjoyable. Ensure you have the following on hand:

  • Cake pans (8-inch round) for baking uniform layers.
  • Piping bags and tips for creating the unicorn’s mane.
  • Offset spatula for smooth frosting application.

Preparing to Bake Your Unicorn Cake

Before diving in, preheat your oven and grease your cake pans. Preparing your tools and ingredients in advance saves time and helps you stay organized.

Preparing and Baking the Unicorn Cake Layers

How to Make the Cake Batter

The foundation of any unicorn cake is its pastel-colored layers. Here’s how to prepare the batter step-by-step:

  1. Combine Dry Ingredients: In a medium-sized bowl, whisk together 2½ cups of all-purpose flour, 2½ teaspoons of baking powder, and ½ teaspoon of salt. Set aside.
  2. Cream the Butter and Sugar: In a large mixing bowl, beat 1 cup of softened unsalted butter with 1¾ cups of granulated sugar using an electric mixer. Mix on medium speed until the mixture is light and fluffy, which takes about 2–3 minutes.
  3. Add Eggs and Vanilla: Beat in 4 large eggs one at a time, ensuring each egg is fully incorporated before adding the next. Stir in 2 teaspoons of vanilla extract for a subtle aroma.
  4. Alternate Dry Ingredients and Milk: Gradually add the dry ingredients to the butter mixture, alternating with 1 cup of whole milk. Begin and end with the dry ingredients. Mix just until combined—don’t overmix!

Coloring the Cake Batter

The pastel hues of a unicorn cake bring its whimsical charm to life:

  1. Divide the batter evenly into 3–4 bowls, depending on how many layers you’d like.
  2. Use food coloring gels to tint each portion. Popular colors include pastel pink, baby blue, soft lavender, and mint green. Add a few drops of gel and mix gently until you achieve the desired shade.

Baking the Cake Layers

  1. Prepare Cake Pans: Grease three 8-inch round cake pans and line the bottoms with parchment paper.
  2. Fill the Pans: Pour each colored batter into its respective pan, spreading it evenly with a spatula.
  3. Bake: Preheat the oven to 350°F (175°C) and bake for 25–30 minutes. Check for doneness by inserting a toothpick into the center; it should come out clean.
  4. Cool the Layers: Allow the cakes to cool in their pans for 10 minutes. Then, gently turn them out onto a wire rack to cool completely before assembling.

Pro Tips for Baking Perfect Layers

  • Ensure all ingredients, especially butter and eggs, are at room temperature for a smoother batter.
  • Don’t skip lining your pans with parchment paper—it prevents sticking and helps layers release effortlessly.
  • For even baking, rotate your cake pans halfway through baking.

Preparing the Buttercream Frosting

How to Make Fluffy Buttercream Frosting

Buttercream frosting is the heart of your unicorn cake, giving it a creamy texture and vibrant look. Follow these steps to create the perfect frosting:

  1. Cream the Butter: In a large mixing bowl, beat 1½ cups of softened unsalted butter with an electric mixer on medium speed. Continue until the butter becomes smooth and creamy, which takes about 2–3 minutes.
  2. Gradually Add Sugar: Add 6 cups of powdered sugar one cup at a time, beating well after each addition. This ensures the frosting is smooth and free of lumps.
  3. Add Vanilla and Heavy Cream: Mix in 2 teaspoons of vanilla extract for flavor and ¼ cup of heavy cream to achieve a silky consistency. Beat on high speed for 3–4 minutes until the frosting is light and fluffy.
  4. Adjust Consistency: If the frosting is too thick, add more heavy cream, one tablespoon at a time. If it’s too thin, incorporate additional powdered sugar.

Coloring the Frosting for the Unicorn Mane

The unicorn mane is the highlight of your cake, so vibrant colors are key!

  1. Divide the frosting into separate bowls based on the number of colors you want for the mane.
  2. Add food coloring gels to each bowl, using pastel shades like pink, blue, purple, and yellow. Mix each color thoroughly until fully blended.
  3. Transfer each colored frosting into piping bags fitted with star tips or rosette tips for easy decorating.

Pro Tips for Perfect Frosting

  • Use Gel Colors: Gel-based food coloring is ideal for achieving vivid colors without altering the frosting’s texture.
  • Chill Your Butter: If your butter becomes too soft, pop it in the fridge for a few minutes before beating. This ensures your frosting stays firm and holds its shape.
  • Test the Piping Tips: Before decorating, practice piping rosettes and swirls on parchment paper to perfect your technique.

Assembling the Unicorn Cake

How to Assemble the Cake Layers

Once your cake layers are cool and the frosting is prepared, it’s time to stack and assemble the unicorn cake. Follow these steps to ensure a sturdy and visually stunning result:

  1. Level the Cake Layers: Use a serrated knife or cake leveler to trim the tops of each layer, ensuring they are flat and even. This step is crucial for stability when stacking.
  2. Start Stacking: Place the first cake layer on a cake board or serving plate. Spread a generous layer of buttercream frosting on top using an offset spatula.
  3. Add More Layers: Repeat the process with the remaining layers, spreading frosting evenly between each. Ensure the layers are perfectly aligned to create a balanced stack.

Applying the Crumb Coat

The crumb coat is a thin layer of frosting that seals in crumbs, creating a smooth base for the final layer of frosting.

  1. Frost Thinly: Spread a thin layer of frosting over the entire cake, smoothing it with an offset spatula. This step doesn’t need to be perfect, as it’s meant to hold crumbs in place.
  2. Chill the Cake: Refrigerate the crumb-coated cake for about 30 minutes. Chilling helps the frosting set, making it easier to apply the final layer.

Smoothing the Final Coat

  1. Frost Generously: Apply a thicker layer of buttercream frosting over the chilled cake. Use an offset spatula or bench scraper to smooth the sides and top.
  2. Perfect the Finish: Rotate the cake on a turntable as you frost to achieve a polished, seamless look.

Preparing the Cake for Decoration

Once the final coat is smooth, return the cake to the refrigerator for another 15–20 minutes. This step ensures the frosting is firm enough to support the decorations, including the horn, ears, and colorful mane.

Decorating the Unicorn Cake

Creating the Unicorn’s Horn and Ears

The horn and ears are the iconic features of a unicorn cake. Follow these steps to craft them using fondant:

  1. Make the Horn:
    • Roll white fondant into a long, thin cone shape.
    • Twist the cone gently to form the signature spiral pattern of a unicorn horn.
    • Brush the horn with edible gold dust to give it a shimmering, magical finish.
    • Insert a toothpick or skewer into the base of the horn to anchor it on the cake.
  2. Shape the Ears:
    • Roll out more white fondant and cut out two teardrop-shaped pieces for the ears.
    • Add smaller pink fondant teardrops inside the white pieces to create the inner ear detail.
    • Pinch the bottom of each ear slightly to give them a curved, lifelike shape.
  3. Attach the Horn and Ears:
    • Place the horn in the center of the cake’s top using the toothpick for support.
    • Position the ears on either side of the horn, securing them with toothpicks or edible adhesive.

Drawing the Unicorn’s Eyes

The eyes add charm and personality to the cake:

  1. Use a black edible gel or marker to draw two closed eyes on the front of the cake.
  2. Add long lashes extending from each eye for a whimsical touch.
  3. If desired, use tiny fondant pieces or edible paint to add extra details, such as glitter accents near the eyes.

Piping the Buttercream Mane

The mane is undoubtedly where creativity truly shines, allowing you to showcase your artistic skills with colorful buttercream frosting. To begin, carefully prepare your piping bags by filling each one with a different color of frosting. Furthermore, make sure to fit the bags with star or rosette piping tips, as these will help create intricate patterns.

Next, start piping the mane near the horn, using smooth, deliberate motions to create swirls, rosettes, and stars. Gradually work your way around the horn and ears, allowing the mane to cascade beautifully down one side of the cake. Additionally, alternate the colors as you pipe to achieve a vibrant and harmonious flow of shades.

Finally, overlap some of the swirls and rosettes for a more dynamic, textured appearance. This layering technique not only adds depth but also enhances the overall visual appeal of the unicorn’s mane. With thoughtful attention to detail and vibrant colors, you’ll bring the unicorn to life in the most magical way.

Adding Final Touches

  1. Sprinkle edible glitter or small decorative sprinkles over the mane for extra sparkle.
  2. Add small fondant flowers, stars, or hearts to embellish the mane and make it even more magical.
  3. Step back and admire your work—it’s a stunning unicorn cake ready to impress!

Serving and Customizing Your Unicorn Cake

How to Serve Your Unicorn Cake

Serving a unicorn cake is as much an experience as creating it. Here’s how to do it right:

  1. Chill Before Slicing: Refrigerate the cake for about 20–30 minutes before serving. This helps the frosting set and makes slicing easier.
  2. Use a Sharp Knife: To maintain the clean layers and designs, use a sharp, non-serrated knife. Wipe the blade clean between slices for perfect cuts.
  3. Showcase the Layers: Serve the cake on a platter that highlights its colorful interior. The pastel layers paired with the vibrant mane create a stunning visual.

Unicorn Cake Customization Ideas

Personalizing your unicorn cake can make it even more special. Here are some creative ways to customize it for specific events or preferences:

  • Add a Rainbow Interior: Use five or six layers in rainbow colors for an even more magical reveal when the cake is sliced.
  • Themed Decorations: Tailor the decorations to suit the event. For example, add stars and moons for a cosmic unicorn or florals for a springtime theme.
  • Flavor Variations:
    • Replace vanilla extract with almond or lemon for a unique twist.
    • Add a chocolate ganache filling between the layers for extra richness.
  • Personalized Touches: Add the recipient’s name or age using fondant cutouts or edible lettering to make the cake more personal.

Pro Tips for Unicorn Cake Success

  1. Work Ahead: Prepare the cake layers and decorations a day in advance to reduce stress on the day of the event.
  2. Transport Safely: If transporting the cake, place it in a sturdy box and keep it chilled until it’s time to serve.
  3. Repurpose Leftovers: Leftover frosting can be used for cupcakes or cookies, and extra cake pieces make delicious cake pops.
