Preheat oven to 350 degrees F (176 degrees C).
Into the bowl of a stand mixer, add Granulated Sugar (300 gram), All-Purpose Flour (300 gram), Baking Powder (2 teaspoon), and Salt (1/2 teaspoon). Mix until well combined.
Into another bowl, add Egg (6) and Milk (6 tablespoon). Beat with a fork to combine.
Into the dry ingredients, add Butter (185 gram) and half of the egg mixture. Beat on low speed for 2 minutes.
Turn speed up to medium and beat for another 2 minutes.
Add remaining egg mixture and beat until smooth.
Transfer batter into a greased bundt pan.
Bake for 45 minutes to 1 hour. It will depend on your oven. Press the top lightly- if it springs back its done.
