Set bread machine to Dough. Put yeast, flour, cinnamon, salt, sugar, butter, and water in machine in the order recommended by the manufacturer and start cycle.
When dough is complete, turn out onto well-floured board and knead 10-20 times.
Butter bundt pan.
In a small saucepan, melt together butter and brown sugar.
Cut dough into 1″ cubes.
Dredge cubes in butter/sugar mixture (Yes, it’s hot. Be careful.) and drop evenly into prepared bundt pan.
Let rise in covered bundt pan for 20m.
Preheat oven to 375°F and continue to let do rise for another 5 minutes.
Bake at 375°F for 20-25 minutes (until golden brown).
To serve immediately, place a plate over the top of the pan and invert them together. You may need to give the bottom of the pan a thump after you’ve got them flipped.
To serve the next morning, leave in pan and reheat at 375°F for 10-15 minutes (until butter/sugar mixture is gooey again). Serve as directed above.
