Step-by-Step Instructions to Make a Stunning Unicorn Cake

Step 1: Prepare the Cake Batter
- Preheat the Oven – Set your oven to 350°F (175°C) and grease three 8-inch cake pans with butter or non-stick spray. Line the bottoms with parchment paper for easy removal.
- Mix the Dry Ingredients – In a medium bowl, whisk together the flour, baking powder, and salt. Set aside.
- Cream the Butter & Sugar – In a large mixing bowl, beat the butter and sugar with an electric mixer until light and fluffy (about 3 minutes).
- Add Eggs & Vanilla – Mix in the eggs one at a time, beating well after each. Stir in the vanilla extract for extra flavor.
- Incorporate the Milk & Flour Mixture – Gradually alternate adding the dry ingredients and milk, starting and ending with the dry mixture. Mix until just combined do not overmix.
Step 2: Bake the Cake Layers
- Divide the Batter Evenly – Pour the batter equally into the three prepared cake pans. Smooth the tops with a spatula.
- Bake – Place in the oven and bake for 25-30 minutes, or until a toothpick inserted in the center comes out clean.
- Cool Completely – Let the cakes cool in the pans for 10 minutes, then transfer to a wire rack to cool completely before frosting.
Step 3: Make the Buttercream Frosting
- Beat the Butter – In a large bowl, beat the softened butter on medium speed until smooth and creamy (about 2 minutes).
- Add Powdered Sugar Gradually – Slowly mix in the powdered sugar, one cup at a time, beating well after each addition.
- Add Cream & Vanilla – Stir in the heavy cream and vanilla extract until the frosting is light and fluffy.
- Color the Frosting – Divide the frosting into separate bowls and tint each portion with gel food coloring (pink, blue, purple, and yellow) to create the unicorn’s mane.
Step 4: Assemble the Cake
- Level the Cake Layers – Trim the tops of each cake layer if needed to ensure a flat, even surface.
- Stack & Fill – Place the first cake layer on a cake board or stand. Spread an even layer of buttercream frosting on top. Repeat with the second layer, then place the third layer on top.
- Crumb Coat & Chill – Apply a thin crumb coat (a light layer of frosting) to seal in crumbs. Refrigerate for 15 minutes before adding the final frosting layer.
Step 5: Decorate Your Unicorn Cake
- Create the Mane – Fill piping bags with different colored buttercream and use a star tip to pipe rosettes and swirls on top and along one side of the cake.
- Make the Unicorn Horn & Ears – Roll out white fondant to shape the ears and twist a piece into a spiral for the horn. Brush the horn with edible gold dust.
- Add Eyes & Finishing Touches – Use black fondant or an edible marker to draw closed eyelashes. Sprinkle edible glitter for extra sparkle!

FAQs – Unicorn Cake Troubleshooting & Tips
Got questions about making the perfect unicorn cake? Here are answers to the most common concerns, along with expert tips to help you avoid mistakes and achieve bakery-quality results.
1. How do I prevent my cake from being too dry?
Measure ingredients accurately – Too much flour can make the cake dry. Use a kitchen scale for best results.
Don’t overbake – Check the cake 5 minutes before the recommended baking time. A toothpick should come out with a few moist crumbs.
Use whole milk – It keeps the cake moist and rich.
2. My buttercream is too runny how do I fix it?
Chill the frosting – Place it in the fridge for 10-15 minutes to firm up before decorating.
Add more powdered sugar – If it’s still too soft, mix in 1 tablespoon at a time until it thickens.
Use real butter – Margarine or low-fat substitutes can cause runny frosting.
3. How do I get vibrant pastel colors without making the frosting too thin?
Use gel food coloring – It provides intense color without altering the texture. Avoid liquid food coloring.
Start with a small amount – A little goes a long way! Add a few drops and mix before adding more.
4. Can I make this cake in advance?
Absolutely! Here’s how to prepare ahead:
Bake the cake layers – Store in an airtight container at room temperature for up to 2 days or freeze for up to a month.
Make the buttercream – Store in the fridge for up to 5 days. Let it come to room temperature and re-whip before using.
Assemble the cake the night before – Keeps everything fresh while allowing the flavors to develop.
5. How do I keep the unicorn decorations from drooping?
Chill the cake after decorating – This helps fondant and buttercream hold their shape.
Use support for the horn – A wooden skewer inserted into the fondant horn will keep it stable.
Keep the cake in a cool area – Avoid placing it near heat or direct sunlight.
6. What’s the best way to store leftover unicorn cake?
Refrigerate in an airtight container – Keeps the cake fresh for 3-4 days.
Freeze slices individually – Wrap in plastic wrap and store in a freezer-safe bag for up to 3 months. Thaw overnight before serving.
7. Can I use a box cake mix instead of making it from scratch?
Yes! If you’re short on time, you can use a high-quality vanilla cake mix and enhance the flavor by:
Replacing water with whole milk.
Adding an extra egg for more richness.
Using melted butter instead of oil for a homemade taste.
