1/8 tsp salt
2 large eggs (50 - 55g / 2 oz each), at room temp (Note 3)

60g / 1/4 cup unsalted butter , cut into 1.5cm / 1/2” cubes

PREPARATION:
Preheat oven to 180°C/350°F (160°C fan) for 20 minutes before starting the batter (Note 8). Place shelf in the middle of the oven.
Place cupcake liners in a standard muffin tin. (Note 9)
CUPCAKE BATTER:
Whisk Dry: Whisk flour, baking powder and salt in a large bowl. Set aside.
Heat Milk-Butter: Place butter and milk in a heatproof jug and microwave 2 minutes on high to melt butter. Do not let milk bubble and boil (foam ok). Cover and leave in microwave to keep very warm (stove: cover with lid and leave on turned off stove). (Note 10)
Mix eggs: In a separate, preferably heavy based glass bowl, beat eggs for 30 seconds on speed 6 of a handheld beater.
Add sugar: With the beater still going, pour the sugar in over 30 seconds.
Beat until tripled: Beat eggs for 6 minutes on speed 8, or until tripled in volume and almost pure white.
Add flour: When the egg is whipped, scatter 1/3 flour across surface, then beat on Speed 1 for 5 seconds. Stop beating, add half remaining flour, then mix on Speed 1 for 5 sec. Add remaining flour, then mix on Speed 1 for 5 - 10 sec until the flour is just mixed in. Once you can’t see flour, stop straight away.
Temper milk: Pour hot milk, vanilla and oil into the now empty flour bowl. Add about 3/4 cups of the Egg Batter into the hot milk (don't need to be 100% accurate with amount). Use a whisk to mix until smooth - you can be vigorous here. Will look foamy.
Slowly add milk: With the beater on Speed 1, pour the Milk mixture into the Egg Batter over 15 seconds, then turn beater off.
Scrape and final mix: Scrape down sides and base of bowl. Beat on Speed 1 for 10 seconds - batter should now be smooth and pourable.
BAKE:
Fill muffin tin: Pour batter into muffin tin, filling 2/3 of the way up. Do not fill more (causes flat / sunken surfaces). Easiest to use a standard ice cream scoop with lever.
Bake 22 minutes or until golden and toothpick inserted into middle comes out clean.
COOL & FROST:
Remove from oven. Cool just 2 minutes then use a fork to help remove and place on cooling rack. Cool completely before icing with frosting of choice (Note 11 for ideas), or cream and fresh berries or jam.
