Step 1

To thaw dough, spray a 9 X 13'-inch baking pan or dish with cooking spray. Place the two frozen loaves into it. Spray a sheet of plastic wrap with cooking spray and place on top of the loaves to prevent sticking as it thaws. Place on counter to rise/thaw for 4-7 hours, until dough is about 1 inch above the edge of the pan. Timing will depend on the room temperature. Or see Note.

Step 2

When ready to assemble, preheat oven to 375 degrees F.

Step 3

Generously coat a 15-cup Bundt pan with cooking spray.

Step 4

In a medium bowl, mix together the granulated sugar and cinnamon.

Step 5

Cut bread loves into 1-inch pieces. Do a few slices at a time because as it continues to rise and thaw, the dough will stick together making it difficult to separate.

Step 6

Using only about 4 pieces of dough at a time, toss the pieces into the cinnamon sugar mixture and coat thoroughly. It is a bit time consuming doing it this way, but it's the best way to prevent all the dough from sticking together, and it will until each piece is coated in the cinnamon sugar.

Step 7

Distribute pieces evenly into prepared Bundt pan. It doesn't have to be neat, but make sure they're all arranged in an even layer, so that it bakes evenly

Step 8

After you have created the bottom layer, sprinkle 4 tablespoons of cinnamon sugar over them. Sprinkle more cinnamon sugar on top of each consecutive layer until no more remains.

Step 9

Sprinkle brown sugar on top of the last layer.

Step 10

Spoon butter over the top.

Step 11

Bake for 30-35 minutes.

Step 12

Place pan on a wire rack to cool upright for 2-3 minutes.

Step 13

Tip over onto a large serving plate or tray and allow to sit for an additional 2-3 minutes before removing the pan.
