Prepare the Long Emile Henry Bread Baker by lightly coating with butter and flour. (Can also be baked in two 4 1/2 x 8 1/2-inch bread pans)
On a well-floured surface, roll the dough to a 1/4-inch-thick rectangle. Spread the grated cheese and jalapeños over the surface of the dough.
Then roll the dough into a log, starting at the short end.
Using a Bread Knife, or Kitchen Scissors cut the log into 4 equal pieces (cut into 8 pieces if using two 4 1/2 x 8 1/2-inch pans).
Set the buns in the prepared baking dish. (If you are baking in a smaller baker, divide the pieces into two prepared pans.)
Cover the buns with the lid and let them rest for 1 1/2 to 2 hours - until you press the dough and it leaves a slight indent. The long rest will ensure that you have a fluffy bun. (You can set these up the night before and let them rest overnight in the refrigerator. In the morning take them out and let them sit on the counter for about 45 minutes to an hour.) You may get away with a slightly shorter rise, but the buns will not be quite as soft.
Preheat the oven to 450°F and place the rack in the middle of the oven.
Bake for about 50 minutes with the lid on (about 40 minutes for the smaller loaf pan). Remove the lid and bake for an additional 10 minutes. When I lifted the lid off the bread it stuck to the cheese a tiny bit, but with a gentle shake, it came loose.
Cool slightly in the pan and then turn the loaf out onto a cooling rack to cool completely before slicing.
