Mix the flours, salt and sugar in a separate bowl.
Measure out the yeast.
Add the ingredients to your bread machine in the order recommended by the manufacturer. Mine is wet, dry then yeast on top.
Set the bread machine to Dough Cycle.
While dough is making, spray or butter a regular muffin pan and set aside. (A regular size tart pan will also work.)
When Dough cycle is finished divide the dough in to 2 equal portions on a lightly floured board.
Roll each half out very thinly - you are aiming for about 2 17" X 8" retangles only a few mm thick.
Carefully spread ½ the soft butter over each piece of dough, being careful not to tear the dough and going right out to the edges.
Sprinkle the chopped up chips over each piece of buttered dough, spreading evenly.
Gently roll each piece of dough length-wise.
Cut each log in half lengthways so you can see the center of the log with all the layers and filling. Then cut each half in to 3 equal portions. You will have 12 pieces of dough.
Twist each piece of dough into a spiral so the cut edges face outward. Place in the muffin tin. Cover with plastic wrap and allow to proof at room temperature 4 hours or in the fridge overnight.
Preheat oven to 375° F. Add cruffins and reduce oven to 350°. Bake for 25 minutes. A toothpick should come out clean from the center.
When done, allow cruffins to cool enough to handle, then transfer to a rack to finish cooling. Dust with icing sugar if desired when completely cool.
Notes
Variation: To make 6 large cruffins, pinch 2 pieces of the cut log together before twisting. Twist and put in a large 6 muffin tin. Bake 35 minutes and check for doneness.
