1. Preheat oven to 350 degrees and line pans with cupcake liners.
2. Sift cake mix into a large bowl ( to help remove any lumps) and add eggs, oil, sour cream, buttermilk and vanilla extract. Stir until smooth.
3. Fill cupcake liners 3/4 full and bake for 15-20 minutes or until an inserted knife comes out clean.
4. Let cool.
5. Frosting: Beat butter, vanilla extract and peppermint extract until smooth. Slowly add in powdered sugar until you reach your desired consistency. Add milk if it gets too thick!
6. Cut out little witch boots and cut straws in half. Hot glue or tape your boots on the straws.
7. Frost cupcakes and then stick in straws with the boots! Ding dong the witch is dead!
