Dust a clean work surface with the remaining 1/4 cup of flour.
Roll the dough out to 1-inch thickness and cut into 1-inch squares.
In a medium bowl, whisk together the sugar and ground cinnamon.
Roll the dough squares in the cinnamon and sugar to coat, working in batches as needed.
Add the coated dough into the bundt pan. Cover with a towel and let rise in a warm place for 30 minutes.
Nearing the end of the rise time, preheat the oven to 350°F.
Bake for 50 minutes. If the dough gets too brown on top, loosely place a piece of tin foil over the bundt pan.
Remove from the oven and let rest for no longer than 5 minutes.
Place a rimmed platter on top of the bundt pan and flip it so the platter is sitting on the counter. Once flipped over, remove the bundt pan.
Let cool slightly and serve up!
