Preheat the oven to 160C (320F) and line the muffin pan with 9 cupcake paper liners.
In a bowl, combine the flour, cocoa powder, baking powder, baking soda, and salt. Set aside.
In another bowl, add the egg, sugar, vanilla extract, and red food coloring. Whisk well to a homogenous consistency.
Add the kefir, butter, and oil and whisk to combine.
Sift in the dry ingredients and fold with a rubber spatula just until no dry ingredients are left.
Fill the paper liners ⅔ full and bake for 25-30 minutes or until a toothpick inserted in the center of the cupcake in the middle of the pan comes out clean.
Remove from the oven and let the cupcakes rest for 5 minutes in the pan. Then, transfer onto a cooling rack to cool down to room temperature before decorating with the cream.
