For the chocolate ganache:
2 cups semi-sweet chocolate chips
1 cup heavy cream
1/4 teaspoon salt

Directions
Preheat your oven to 350°F (175°C). Line a 12-cup muffin pan with cupcake liners.
In a large mixing bowl, cream together the sugar and softened butter until light and fluffy.
Add the melted coconut oil and mix until combined.
Beat in the eggs one at a time, then stir in the vanilla extract and peppermint extract.
In a separate bowl, whisk together the flour, cocoa powder, baking powder, baking soda, and salt.
Gradually add the dry ingredients to the wet ingredients, alternating with the milk. Mix until just combined. Do not overmix.
Divide the batter evenly among the cupcake liners, filling each about two-thirds full.
Bake for 18 to 22 minutes, or until a toothpick inserted in the center comes out clean.
Allow the cupcakes to cool in the pan for 5 minutes, then transfer them to a wire rack to cool completely.
To make the frosting:
10. Beat the softened butter until smooth and creamy.
11. Gradually add the confectioners’ sugar, mixing on low speed until incorporated.
12. Add the peppermint extract and heavy cream. Beat until light and fluffy.
13. Add green food coloring if desired and mix until evenly tinted.
14. Pipe or spread the frosting onto completely cooled cupcakes.
To make the ganache:
15. Heat the heavy cream in a small saucepan until it just begins to simmer.
16. Pour the hot cream over the chocolate chips in a heatproof bowl. Let sit for 2 to 3 minutes.
17. Stir until smooth and glossy, then mix in salt and vanilla extract.
18. Allow the ganache to cool slightly before spooning it over the frosted cupcakes.
