How to Make Unicorn Fudge
- Step 1 – Prepare the pan. Line an 8X8 baking pan with foil or line the pan parchment paper and spray with a non-stick cooking spray for easy removal of the fudge.

Step 2. Melt the chocolate chips in a microwave-safe bowl. Heat in 30 second increments and stir between each one. Heat until the chocolate is completely melted.

Step 3. Stir in the vanilla frosting.

Step 4. Then separate the mixture evenly into 3 bowls. Stir in the pink food coloring, purple food coloring and blue food colouring into each one of the bowls until each bowl is your desired shade.

Step 5. Next, drop a spoonful of each color into the 8X8 pan using a random pattern.

Step 6. Swirl the fudge with a knife. Run it through the fudge to create a swirl pattern. Don’t swirl excessively so that you still have the contrast of the colors.

Step 7. Top with marshmallows and sprinkles. Gently press them down into the fudge. Refrigerate the fudge for 2-3 hours until the fudge is set. Then cut and enjoy.

Storage
Store the leftovers in an airtight container at room temperature for up to 1 month or freeze for up to 3-4 months. Allow to thaw at room temperature before serving if frozen.
Make sure to use a freezer container or bag. We recommend placing wax paper between the layers of fudge.
Pro Tips
- Don’t overcook the chocolate. It is important to melt this in intervals to avoid burning it.
- Swirl the colors gently. Use a knife to swirl the different colors together. Be careful that you do not swirl too much or you risk blending everything together. It will not be as pretty if this happens.
- Press the topping. Make sure to add the topping before the fudge mixture sets or it will not stick. You might also want to gently press it into the fudge to secure it.
- Line the pan. Not only does this help with clean up but it makes it easy to remove for cutting. You can lift the fudge out easily and place it on a cutting board to cut.
