Preheat your oven to 170°C (fan) / 190°C (conventional).
Line a 12-hole cupcake or muffin tin with paper cupcake cases.
Using a hand mixer or stand mixer, beat together softened butter and sugar until light and fluffy (about 3-4 minutes).
125 g Unsalted butter, 125 g Caster sugar
Beat in the eggs one at a time, ensuring each is fully incorporated.
2 Free-range eggs
Add vanilla extract and mix thoroughly.
1½ tsp Vanilla extract
In a separate bowl, combine the flour, baking powder, and salt.
125 g Plain flour, 1½ tsp Baking powder, 1 Pinch Salt
Gradually fold the dry mix into the wet mix.
Gently stir in milk until the batter reaches a smooth, drop-consistency.
2 tbsp Whole milk
Divide the batter evenly among the cases (about 2/3 full).
Bake for 18–20 minutes until lightly golden and a skewer comes out clean.
Let the cupcakes cool in the tin for 5 minutes, then transfer to a wire rack before frosting.
