Instructions
Prepare the dough Whisk the warm milk 2 Tablespoons sugar and the yeast together in the bowl of your stand mixer fitted with a dough hook or paddle attachment. Cover and allow mixture to sit for about 5 minutes or until foamy on top. If you do not own a mixer you can do this in a large mixing bowl and in the next step mix the dough together with a large wooden spoonsilicone spatula. It will take a bit of arm muscle. A hand mixer works but the sticky dough repeatedly gets stuck in the beaters. Mixing by hand with a wooden spoon or silicone spatula is a better choice.
On medium speed beat in the remaining sugar which should be 12 cup100g and the softened butter until it is slightly broken up. Add the eggs vanilla and salt and beat on medium speed until combined. The butter wont really be mixing into the mixture so dont be alarmed if it stays in pieces. Switch the mixer down to low speed and with it running add 1
