Heather’s Recipe Notes and Tips

• French Vanilla cake mix is really just vanilla cake with extra vanilla flavoring. Want normal vanilla? Use regular vanilla cake mix or make them from scratch!
• Bake your mini Halloween unicorn cake in fun Halloween-themed cupcake liners!
• When it comes to food coloring, what you use matters. I recommend using pastes or gels instead of liquid food coloring.
• When using food coloring gels, remember that a little goes a LONG way! You can always add more but you can’t remove it. Start with small amounts and gradually add more until you get the color you want.
• Get the marbled effect in your cupcakes by alternating spoonfuls of each colored cupcake batter as you add them to the liners.

Frosting Tips

• Feel free to adjust the amount of powdered sugar and cream slightly in order to reach the frosting consistency that you want.
• Make sure that cupcakes are completely cool before you frost them or the frosting will melt – which is never good!
• For the second layer of frosting, use a piping bag fitted with a star tip for the frosting swirl. It’s completely worth investing in an affordable set of piping tips!

Enjoy! I hope you love this mini Halloween unicorn cake idea. Happy Halloween!
