These were an experiment gone well with requests to make them more often :-)
The brioche dough was made in the bread machine following the recipe that came in the machine's booklet with a few added extras. They're not too sweet either as I reduced the amount of sugar to half.
Here's the recipe if you'd like to have a go at making them yourself.
Chocolate and walnut buns
1 teaspoon easy bake yeast
250g strong white flour
1 tablespoon unsweetened cocoa powder
1/2 teaspoon mixed spice
1/2 teaspoon cinnamon
One and a half tablespoons caster sugar
75g butter, softened
Pinch of salt
2 eggs, lightly beaten
2 tablespoons milk
1/2 bar of dark chocolate, chopped
Handful of walnuts, chopped
Put all the ingredients above, except for the last two, in the bread pan in the order listed and select the basic dough cycle (2h 20ms in my machine).
When the cycle finishes tip the dough from the pan onto a floured surface.
Roll out the dough to a rectangle and sprinkle the chopped chocolate and walnuts all over.
Roll up the dough and cut into slices. Place these, cut side up, in a square tin lined with greaseproof baking paper.
Cover with a plastic bag, making sure the bag is not touching the dough, and prove for 40 to 50 minutes in a warm place. I found that the airing cupboard is perfect for proving dough.
Bake in a preheated oven to 150º for about 30 minutes.
