I searched some easy ideas below. I may make one of them this year : )
Below are all easy-to-make cake tops (with recipes for making cupcakes), hope that can be useful to you too!
1. Santa Claus Hat
2. Santa Claus Face
3. Ice-cream cone X'mas Tree
7. Cup of drink with candy stick
8. Snowflake top
9. Ornament decorations
This recipe is for cookies, but I like the top decoration. It is so easy to make and so cute!
11. X'mas Wreath
The recipe is not for cup cake. But we can make the decoration like this. It is not difficult but elegant!
