- 1 teaspoon baking powder
- ¼ teaspoon baking soda
- ¼ teaspoon salt

- ½ cup (50g) cocoa powder
- 2 - 3 tablespoons milk

Instructions
For the Cupcakes
- Preheat the oven to 180C/350F/Gas 4. Line a 12-cup muffin tin with muffin cases, and set aside.
- Whisk together the flour, baking powder, baking soda, and salt. Set aside.
- Whisk together the eggs and egg yolk. Add the sugar, and whisk until combined. Add the vanilla extract, butter, and yogurt, and whisk until combined. Fold in the dry ingredients.
- Divide the batter evenly between the muffin cases, filling only 2/3 full.
- Bake for 14 - 16 minutes, or until a toothpick inserted into the centre comes out clean.
- Allow to cool for 5 minutes in the pan, before transferring them to a wire rack to cool completely before frosting.
For the Frosting
- Using a handheld or stand mixer, beat the butter until light and creamy. Add half the icing sugar, and beat until smooth. Add the cocoa powder, vanilla, and 1 - 2 tablespoons of milk, and beat until smooth.
- Add the remaining icing sugar, and beat until smooth. Add more milk to reach desired consistency. Transfer the frosting to a piping bag, and frost the cooled cupcakes.

Cupcakes can be made 1 day in advance, covered, and stored at room temperature. Cover the frosting, and store in the fridge until ready to use.
