How to Make Easy Unicorn Petit Fours Recipe
Step 1: Prepare Your Pan and Oven
Preheat your oven to 350 degrees Fahrenheit and spray your petit four baking pan with a baking spray like PAM. This step is crucial to ensure your little cakes don’t stick and come out perfectly shaped.
Step 2: Mix the Wet Ingredients
Grab a large mixing bowl and whisk together the eggs, oil, and milk until everything is smoothly combined. This rich and silky mixture sets the foundation for a tender cake crumb.
Step 3: Separate the Batter
Divide the cake batter evenly into four small bowls—this is where the magic of the unicorn colors really begins!
Step 4: Add Color to Your Batter
Stir pink gel food coloring into one bowl, sky blue into the next, purple in the third, and leave the fourth bowl plain. These vibrant bowls of batter will soon transform into adorable multi-colored cupcakes.
Step 5: Spoon Batter into the Pan
Using a teaspoon, carefully spoon about 1 teaspoon of each colored batter into individual cavities of the petit four pan. Layer or swirl for an even more whimsical effect if you wish.
Step 6: Bake to Perfection
Bake the batter for 15 minutes or until a toothpick inserted into the center comes out clean. This baking time will give you moist, springy petit fours that are just the right size for a single bite.
Step 7: Cool and Remove
Take the pan out of the oven and gently remove the petit fours onto a wire rack. Let them cool completely; this step is key before you move on to frosting.
Step 8: Prepare the First Frosting Layer
Scoop one container of vanilla frosting into a microwave-safe bowl and heat for 15 to 20 seconds to achieve a pourable consistency. This will give your petit fours a smooth, glossy coating.
Step 9: Frost the Petit Fours
Carefully pour the warmed frosting over the cooled petit fours, making sure each cake is fully coated. Let this layer set and firm up before moving to the next decorating step.
Step 10: Color the Second Frosting Batch
Divide the second container of frosting into four bowls, mixing pink, blue, purple, and black gel colors into their respective bowls. These vividly colored frostings will be used for absolutely adorable unicorn details.
Step 11: Pipe Unicorn “Hair” and Details
Fill piping bags fitted with star and round tips with the pink, blue, purple, and black frostings. Use the pink and blue for luscious swirls of “hair,” add purple dots for depth, and detail the eyes with black frosting. This is the stage where your petit fours truly come to life!
Step 12: Add the Unicorn Horn
Gently place a unicorn horn sprinkle on top of each petit four at the center, crowning your colorful creations with their signature magical accent.
Step 13: Chill Before Serving
Allow the decorated petit fours to firm up for 30 minutes so that the frosting sets beautifully. Then get ready to watch everyone’s faces light up as they taste these enchanting cakes.
How to Serve Easy Unicorn Petit Fours Recipe

Garnishes
Adding a few edible glitter sprinkles or mini rainbow nonpareils can elevate your petit fours to even greater levels of sparkle and charm. Fresh edible flowers also pair beautifully for a whimsical touch.
Side Dishes
Serve these petite cakes alongside light refreshments like sparkling lemonade or a fruity tea to complement their sweet vanilla flavor without overpowering the palette.
Creative Ways to Present
Arrange your unicorn petit fours on a pastel-colored platter, or display them on a tiered cake stand for a magical centerpiece at any celebration. For an extra special touch, place each petit four in a delicate cupcake liner that matches your color theme.
Make Ahead and Storage
Storing Leftovers
Store any leftover petit fours in an airtight container in the refrigerator to keep the frosting fresh and firm. They’re best enjoyed within 3 days for optimal taste and texture.
Freezing
You can freeze unfrosted petit fours by wrapping them tightly in plastic wrap and placing them in a freezer-safe bag. Thaw completely and frost just before serving to maintain freshness.
Reheating
Since petit fours are best enjoyed chilled or at room temperature, avoid reheating. If you prefer, let them come to room temperature for about 15 minutes after refrigeration before serving.
FAQs
Can I use a different cake mix flavor for this recipe?
Absolutely! While the French vanilla is perfect for a light, classic taste, you can experiment with other flavors like almond or lemon to add a unique twist to your unicorn petit fours.
What if I don’t have a petit four pan?
No worries! You can bake this batter in mini muffin tins or small silicone molds, just adjust baking time slightly and carefully monitor doneness.
Are there alternatives to gel food coloring?
Gel colors provide vibrant hues without watering down the batter, but you can use liquid food coloring—just use less to avoid affecting the texture.
Can these petit fours be made gluten-free?
Yes! Simply substitute the cake mix with a gluten-free vanilla cake mix, and ensure all other ingredients are gluten-free certified.
How long does the frosting need to firm up before decorating?
After the initial frosting pour, letting the petit fours set for about 20 to 30 minutes helps create a smooth base that’s easier to pipe detailed decorations onto.
