Step 1

In a large bowl, mix the unsweetened cocoa powder, baking soda, and boiling water. Mix until smooth, then let cool to room temperature.

Step 2

In another bowl, mix the butter, vegetable oil, sugar, pure vanilla extract, salt, eggs, egg yolks, evaporated milk, and mix well. Slowly pour the chocolate mixture into the wet mixture, and then fold in the flour.

Step 3

Line your muffin tin with cupcake liners, and then fill about 2/3 the way full. Place the pan into the air fryer and air fry at 320 degrees F, air fryer setting, for 10 to 12 minutes. Or until a toothpick inserted into the middle of the cupcake comes out clean.

Let cool before decorating.
