- ½ teaspoon baking soda
- ¼ teaspoon salt
- 1 ½ cups granulated sugar
- ¾ cup unsalted butter, softened (vegan butter works well for dairy-free options)
- 4 large eggs
- 1 cup buttermilk (or 1 cup milk + 1 tbsp lemon juice/vinegar)
- 2 teaspoons vanilla extract
- For the Buttercream Frosting:
- 1 cup (2 sticks) unsalted butter, softened
- 3-4 cups powdered sugar
- ¼ cup milk
- 1 teaspoon vanilla extract
- Gel food coloring: Pastel pink, purple, blue, and yellow.

Timing
Prep time: 30 minutes
Bake time: 30-35 minutes
Frosting and decorating: 45-60 minutes
Total time: Approximately 1 hour 45 minutes – 2 hours (20% faster than many similar recipes!).
Step-by-Step Instructions
Step 1: Prepare the Cake Batter. Preheat oven to 350°F (175°C). Grease and flour two 9-inch round cake pans. In a large bowl, whisk together flour, baking powder, baking soda, and salt. In a separate bowl, cream together butter and sugar until light and fluffy. Beat in eggs one at a time, then stir in vanilla. Alternately add the dry and wet ingredients, beginning and ending with the dry. Don’t overmix!
Step 2: Bake the Cakes. Divide batter evenly between prepared pans. Bake for 30-35 minutes, or until a wooden skewer inserted into the center comes out clean. Let cool in pans for 10 minutes before inverting onto wire racks to cool completely. Pro Tip: For perfectly even layers, use a cake leveler once the cakes are completely cool.
Step 3: Make the Buttercream Frosting. In a large bowl, beat butter until light and fluffy. Gradually add powdered sugar, alternating with milk, until smooth and creamy. Stir in vanilla extract. Divide frosting into four bowls and tint each with a different pastel color.
Step 4: Assemble the Cake. Place one cake layer on a serving plate. Frost the top with a layer of each pastel-colored frosting, creating a swirl effect. Top with the second cake layer and frost the entire cake with a thin layer of buttercream (crumb coat). This prevents crumbs from getting into your final frosting layer.
Step 5: Decorate the Cake. Use the remaining frosting to create a beautiful unicorn horn using a piping bag or knife. Decorate generously with rainbow sprinkles, edible glitter, marshmallows, and pretzel sticks. Add fresh flowers for that extra special touch if you like.

- Saturated Fat: 9-12g
- Sugar: 40-50g
- Protein: 4-5g
Healthier Alternatives for the Recipe
- Substitute refined sugar with honey or maple syrup for a touch of natural sweetness.
- Use whole wheat flour for added fiber. This might slightly alter the texture.
- Opt for Greek yogurt instead of buttermilk for a protein boost.
- Reduce the amount of butter in the frosting, and increase the amount of milk to achieve a lighter consistency.
Serving Suggestions
Serve your magical unicorn birthday cake as the centerpiece of the party table. Cut into slices and arrange on elegant plates. You can also add personalized cake toppers with each child’s name for an extra special touch. Consider serving it alongside rainbow-colored fruit skewers, for a healthy and themed accompaniment.
Common Mistakes to Avoid
- Overmixing the batter: Overmixing develops gluten, resulting in a tough cake. Mix until just combined.
- Underbaking the cakes: Use a toothpick to check for doneness; it should come out clean.
- Using too much frosting: A thin crumb coat is key to a smooth finish. The aesthetic is paramount here!
- Not allowing the cakes to cool completely: Frosting a warm cake will cause the frosting to melt.
Storing Tips for the Recipe
Store leftover cake in an airtight container in the refrigerator for up to 3 days. For best results, frost the cake right before serving to maintain optimal texture and fresh look. The buttercream can be made a day ahead and stored in a separate airtight container in the refrigerator.
