Preheat the oven to 350°F.
Put the melted butter, vanilla extract, eggs and milk into a medium bowl and whisk together well.
In another bowl, whisk together the cocoa powder, sweetener, baking powder, Keto Chow, konjac flour and powdered gelatin until completely mixed.
Add the dry ingredients to the egg and butter mixture in 4 separate additions, mixing well between each addition.
Using a 1/4 cup, spoon the mixture evenly into 12 silicone muffin cups in a muffin pan.
Bake for 18 minutes.
Remove from the oven and carefully flip each silicone cup onto a cooling rack and let the cupcakes cool.
Once completely cooled, pipe Mocha Buttercream* onto each cupcake.
Store cupcakes in an airtight container in the fridge.
