Step by step guide

Step 1: Bake the Cake Layers

Start by preparing your cake batter using a vanilla base, either from scratch or a box mix. Divide the batter evenly into 3 to 4 bowls and add a few drops of pastel gel food coloring to each—think soft pinks, purples, blues, and yellows. Gently mix the colors until fully blended, then pour each one into greased round cake pans. Bake according to your recipe’s instructions until a toothpick inserted into the center comes out clean. Once baked, allow the layers to cool completely before moving on. Want to get creative with flavor? You can add a fruity twist with ideas like these strawberry cheesecake bars from QuicklyTaste.com.

Step 2: Prepare and Color the Buttercream

Whip buttercream frosting until it’s light, smooth, and fluffy. Divide it into several bowls and tint each with your chosen pastel shades. For best results, use a color mixing chart and test on a napkin first to check the hue.

Step 3: Stack and Frost Your Cake

Layer the cakes with buttercream in between, apply a crumb coat, chill, and then frost the entire cake smoothly. For visual ideas, check out the cotton candy cake from QuicklyTaste.

Step 4: Add the Unicorn Features

Top your cake with fondant or pre-made unicorn horns and ears. Pipe colorful buttercream swirls to create the mane, then finish with sprinkles, edible glitter, and piped eyes. For inspiration, check out ideas on Pinterest.

Step 5: Tips for Success

Chill between steps, level your cake layers, use support dowels for tall cakes, and most importantly—have fun and embrace the magic!

How to Slice and Store Your Cake

Use a sharp knife dipped in hot water for smooth slices. Store leftovers in an airtight container in the fridge. Let slices come to room temperature before serving for the best texture.
