Preheat oven to 350 degrees.
Into a stand mixer add softened butter & sugar. Beat on medium speed until combined. Add in eggs, beat again until mixed.
Add vanilla, baking powder, baking soda, salt & milk. Beat on low speed and slowly add in flour. Beat on high heat for 1 minute until batter is formed.
Line 2 muffin tins with cupcake liners. Add 2 tbsp worth of batter into each liner (it will be almost completely full).
Bake for 20 minutes until cupcakes are spongy & begin to turn golden brown on the edges.
Remove from oven. Allow to completely cool before adding frosting. Serve & enjoy!
