Simply put: make your favourite bread dough. When it has risen, gently work in your favourite muffin flavourings. Shape into small rolls on a greased baking sheet to rise for up to an hour. Bake for half the time the loaf would have taken. Devour with delight.
To make one large loaf, my recipe is:
1 1/4 cups tepid water
3 Tbsp extra-virgin olive oil
3 Tbsp blackstrap molasses
1/2 tsp salt
4 cups strong wholemeal flour
1/3 cup ground flax seeds
1 1/4 tsp yeast
in that order in my bread machine, on dough setting.
This is sufficient dough for 12 large rolls. Divided the risen dough into batches, to gently work in the flavourings e.g. lightly crushed mixed nuts, cocoa powder with a little sugar, or chilli flakes. Into the centre of each chocolate roll, I embedded three chunks of dark chocolate.
Form into rolls, allow to rise for up to an hour on two greased baking sheets, and then bake at Gas Mark 6 / 400 F / 200 C for ~20 mins, swapping the sheets around at half-time for even cooking. (Notice, it's much quicker than baking a loaf, too).
Allow to cook on a rack for 5 mins, then devour ... Gastrogasm! ... and the bread never has a chance to go stale...
