Let’s Get Baking: Step-by-Step

Preheat the Oven
Begin by preheating your oven to 350°F (175°C). Prepare two 9-inch round cake pans by greasing and flouring them, or alternatively, line them with parchment paper to ensure that your cake comes out easily without sticking.
Mix the Cake Batter
Mix the flour, baking powder, and salt in a medium-sized bowl. Beat the sugar and butter together in a another, bigger basin for 3–4 minutes, or until the mixture is light and fluffy. One by one, add the eggs, making sure each is well combined before adding the next. Lastly, add the vanilla extract and mix to provide flavor
Add the Dry Ingredients & Milk
Alternate between adding the dry ingredients and the milk to the butter mixture gradually. Mix gently until just incorporated, starting with the dry ingredients and finishing with them. The texture of the cake may be impacted if you overmix.
Color the Batter
For a fun and vibrant look, divide the batter evenly into several bowls. Add a few drops of food coloring to each bowl, stirring until you achieve the desired shades. Whether you prefer bold, bright hues or softer pastel tones, this step allows you to bring your creativity to life.
Bake the Cakes
Carefully pour the different colored batters into the prepared cake pans. You can swirl the colors together gently for a marbled effect, but avoid mixing too much to preserve the distinct color layers. A toothpick inserted in the center of the pans should come out clean after 25 to 30 minutes of baking in a preheated oven. After letting the cakes cool in the pans for ten minutes, move them to a wire rack to finish cooling.
Make the Buttercream Frosting
While your cakes are cooling, prepare the buttercream frosting. Beat the butter in a bowl until smooth and creamy. One cup of powdered sugar at a time, add it gradually while thoroughly mixing. Once fully combined, add the heavy cream, vanilla extract, and a pinch of salt, then continue beating for 3-5 minutes until the frosting is light and fluffy.
Assemble the Cake
Once the cakes have cooled, place one layer on your cake stand or serving plate. Spread a thin layer of frosting over the top to help the second layer adhere. Add the second cake on top and apply a thin crumb coat of frosting to the entire cake. Chill the cake for about 20 minutes to set the crumb coat before moving on to the next step.
Frost the Cake
After the cake has chilled, apply a thicker layer of frosting over the crumb coat. Use an offset spatula to smooth the frosting, keeping the look as neat or as playful as you prefer. Perfection isn’t required—this cake is all about having fun and celebrating creativity!
Decorate Your Unicorn Cake
Now for the magical touch! If you’re using fondant, roll it out and shape it into unicorn ears and a horn. Attach them to the top of the cake. Then, use the remaining frosting to create swirls in your choice of colors. Feel free to add sprinkles, edible glitter, or colorful candies to bring your unicorn cake to life.
Serve and Enjoy
Once decorated, slice the cake and enjoy the delicious results. The bright colors and whimsical design
Pro Tips and Variations
- Swirling the Colors: Don’t be afraid to get creative with the colors! Gently swirl them with a knife or skewer for a marbled effect. But don’t overdo it—keep the swirls soft for the best result.
- Fondant Decorations: If you’re new to fondant, just stick with the basics—ears and a horn. You can always buy pre-made decorations to save some time.
- Flavor Variations: This is a classic vanilla cake, but you can easily switch it up! Add some almond extract or lemon zest to the batter for a twist, or even throw in some cocoa powder for a chocolatey spin.
- Frosting Tips: If you love cream cheese frosting, feel free to swap some of the butter with cream cheese for a tangy flavor.
Serving Suggestions

- For a Party: Serve this unicorn cake with other colorful treats, like rainbow cupcakes or unicorn-shaped cookies, to create a full-on magical dessert table.
- With a Fun Drink: Pair it with milkshakes, hot chocolate, or a colorful punch to keep the fun vibe going.
