Preheat oven to 350°
Prepare a cupcake pan with 12 portions with cupcake liners.
You do not need a mixer for this recipe, but you can use it if you'd like. I use a whisk and a spatula.
In a medium bowl place cocoa, baking soda and boiling water and whisk to combine. Set aside until needed.
In a large mixing bowl whisk the melted butter, oil, sugar, vanilla, and salt together.
Mix in the eggs.
Add the flour, cinnamon, cayenne, and baking powder to the cocoa mixture, whisk until combined.
Add the heavy cream and mix until combined.
Place 3 tablespoons of cupcake batter into each cupcake liner.
Bake for 18-20 minutes or until a toothpick comes out clean.
Allow cupcakes to cool for 5 minutes, then remove cupcakes from pan and place them onto a cooling rack to cool completely.
