Dissolve the yeast in milk with 1tsp of your sugar. Let it sit until the mixture begins to foam. It will be about 5 minutes.
Add in the remaining sugar, butter, salt, eggs, and flour.
Mix until a dough forms.
Grease a large glass bowl, and place the dough inside. Cover completely and set in a warm place in your kitchen. Allow it to rise for 1 hour or until it doubles in size.
Combine brown sugar and cinnamon in a bowl until it makes a fine sand.
Roll out dough on a lightly floured surface until it reaches about 15” x 12”. You want it to be about 1/4” thick.
Spread your softened butter over the surface and then sprinkle with your cinnamon sugar mix.
Spread your blueberries evenly throughout.
Tightly and carefully, roll your dough up into a tight roll.
Cut the dough into 1 1/4”-1 1/2” slices.
Place the cinnamon rolls into a greased 13” x 9” baking dish.
Preheat your oven to 350F.
Cover the rolls loosely with a kitchen towel and allow them to rise for about 30 minutes (until they double in size)
Bake in the oven for 20-25 minutes, until they are cooked through and just starting to brown.
Mix together the icing ingredients with an electric mixer until it is creamy and smooth.
Once the cinnamon rolls have come out of the oven, place the icing on while they are still hot.
If you’d like, you can also top with additional warmed blueberries.
Notes
If your yeast does not begin to foam after 5 minutes, you need to throw it out and start over. It means the yeast is bad and did not activate.
