Preheat a fan-forced oven to 140°C / 275°F or a conventional oven to 160°C / 320°F. Line a cupcake tin with brown cupcake liners.
Add the flour, sugar, cocoa powder, bicarbonate of soda and salt to a large mixing bowl. Mix on low speed with a hand mixer until combined.
Next, add the softened butter and continue mixing on low speed until the mixture reaches a crumbly, sand-like texture.
Add the eggs and milk and mix again on low speed until all the dry ingredients are incorporated. Scrape down the side of the bowl and mix for a final 20 seconds.
Fill each liner just below three-quarters of the way. Using an ice-cream scoop to transfer the batter to the cupcake liners makes this a quick and easy process, and ensures each liner contains exactly the same amount of batter and that the cupcakes will bake evenly. Bake for 40–50 minutes, or until a toothpick inserted in the centre of a cupcake comes out clean. Allow the cupcakes to cool completely on a wire rack before frosting.
These cupcakes are perfectly paired with my vanilla or chocolate flavoured buttercream frosting. Fit the end of a piping bag with whichever piping tip you like and frost a swirl on top. Sprinkle with sprinkles!
Notes
Cupcakes can be stored in an airtight container for up to three days.
