First, preheat the oven to 350°F (180°C). Then, line a cupcake pan with cupcake liners. We love using black ones to add to the warm autumn theme of these cupcakes. You can also use reusable silicone cupcake liners, or simply spray the pan with non-stick baking spray.
Whisk together the eggs, oil, milk, and vanilla extract. Then, add the Duncan Hones cake mix to the liquid ingredients and whisk them together well. You can use a hand whisk or an electric mixer. Mix until you have a smooth and uniform batter. It shouldn't be too thick or thin - this batter should have a regular cupcake batter consistency. Fill the cupcake liners with the batter until they are about two-thirds (2/3) full for the perfect fluffy cupcakes. Bake the cupcakes in your preheated oven for roughly 18-22 minutes. To test whether your cupcakes are done, use a toothpick or cake testing needle. It should come out clean (without any batter on it).
While the cupcakes are baking and cooling, make the cream cheese frosting. To start, cream together the softened cream cheese and salted butter. Make sure to beat them until they are light in color and have a fluffy texture. Whisk in the vanilla extract. Then, add the sifted powdered sugar and mix until you have a completely smooth frosting. If your frosting is too stiff, you can add a teaspoon of milk or water at a time, beating between additions until you have a perfect consistency.
Fit a piping bag with a piping nozzle of your choice. Fill the piping bag with your homemade cream cheese frosting. Then, once your cupcakes are cooled, pipe some frosting onto each cupcake. You can have a look at this tutorial to see the different nozzles pipe frosting and the correct technique to use when piping.
