It's easy to prepare the dough in your bread machine. You could use any frozen fruit. Just make sure you smash it a bit.

Instructions
Please read my tips and tricks below.
Place ingredients in order recommended by the manufacturer of your bread machine. (They should be warm 80-90F/ 26-32C.
Watch your dough ball form. It should be smooth and slightly tacky. Poke around with a spatula. Making sure the flour is mixed in. If necessary add a tsp of liquid or flour to create the right consistency. The dough will rise in the machine.
Remove the dough and place on a clean surface. I didn't lay down flour. With a rolling pin roll out a rectangle 12x18. Not sure how big? See my trick below!
Now blend together your sugar and cornstarch for the blueberries. The should be removed from the freezer and used FROZEN. Smash at least 1/3 to 1/2 of the blueberries. I used a potato masher to help crush them. Work quickly.
Toss the blueberries onto the rectangle. With the long end. Roll tightly. (Picture below.) Now divide your dough. I cut in half. Then those in half and then those into 3 pieces. I recommend a serrated knife. Work quickly and place in a lightly greased 9x13 pan.
Cover your dough with plastic wrap. You want humidity to form. (Cloths won't work.) Cover with a few tea towels and let rise. This may take a while. Your cold berries will warm up and juice will melt into the pan. No worries.
When the dough has fully risen. This is likely 2 1/2 to 3 hours. Why so long? The frozen berries retard the yeast. This actually gives the dough enhanced flavour. It's worth it.
Place rolls in a 350F/175C on middle rack. Bake 25-30 minutes. If your rolls are getting very brown at the 20 minute mark; cover with foil.
While rolls are baking, prepare the frosting. Mix together frosting ingredients and set aside.
Immediately, after removing rolls from oven place 1/3 of frosting all over the rolls. Spread with an offset spatula. Let cool another 30-40 minutes and spread remaining frosting.
Enjoy!
Susie's Tips and Tricks
If you use volume rather than weights be sure and scoop the flour with a spoon into a measuring cup. Don't scoop your measuring cup. You'll end up with too much flour. No tapping the cup. Do not sift flour for bread making.
Adjust your dough ball about 5 minutes in. Start with a lesser amount of flour. Just a couple tablespoons. Using the full amount and adding as you see the dough form is best.
Don't have a way to check your size? Use a dollar bill! US and Canadian paper money is about 6" long. Perfect for helping you determine a 12x18 rectangle.
