Melt the butter, milk and maple syrup together (about a minute in the microwave), just until the butter is mostly melted. Stir and leave to sit for a minute.
Add 300g (2½ cups) flour, yeast and salt to your stand mixer bowl.
Add the butter mixture along with the egg.
Mix everything together, adding more flour as needed (see note 3).
The dough is ready when it has pulled away from the sides of the bowl and falls slowly from the hook when lifted.
Cover the dough and leave to rise for 30 minutes.
Preheat the oven to 175℃ (350℉).
Melt the additional butter and brush some over your dish – mine is 20cm x 20cm (8" x 8"). The rest will be used to brush over the bread after baking.
On a very well floured surface (I use a silicone mat), pour out the dough. Cover with more flour, but don’t work it in.
Divide into 12 equal-sized pieces and roll them into rough balls. Use a little flour on your fingers if the dough is sticky.
Place the balls right next to each other (without much space) so the dough rises upwards rather than spreading out.
Bake for 14-17 minutes until golden brown on top.
Brush with butter and leave to cool slightly. Enjoy!
