• For the Dough
• In the bowl of your stand mixer fitted with the dough hook, Add yeast, warm milk and 1 tbs of measured out sugar. Stir together lightly and allow to sit for 10 minutes or until foamy on top. Stir in remaining sugar, salt, vegetable oil, buttermilk and beaten eggs until combined
• Using a dough hook with your mixer, add in the rest of the sugar and salt and mix for a couple of seconds on low speed. Add 3 cups of flour first and then add one tablespoon at a time until you have a workable dough. The dough WILL still be sticky so do not over-flour your dough! It should be sticky but not sticky enough where it sticks to your hands. Also note that your dough may not completely stop sticking from the bottom of the bowl so don't base your flour additions on that.
• Put your kneaded dough in a large greased bowl and drape a damp cloth on top. Set in a warm place to rise about 1-2 hours until it has doubled in size.
• Pro tip: I like to turn my oven to 170°F then turn it off and rise my dough in there.

For the berry preserves

• Add frozen berries and sugar to a medium sized saucepan. Let them cook down a bit, about 3-4 minutes. Once the juices start flowing and it is getting more liquid-ey, mix cornstarch and water together and pour into saucepan. Let the mixture thicken for about 5 minutes. Pour into a bowl let it cool down completely before using.
• Once the dough is doubled, punch it down. Flour a large surface with lots of flour. Knead the dough for a second so it comes together, then roll out a 20x30 rectangle or as close as you can get to it.
• Spread very soft butter all over the dough making sure to leave a 1 inch line at the bottom for easy closure.
• Spoon berry preserves over butter and spread until evenly distributed.
• Start rolling the dough towards you in a log, ending at the empty line at the bottom and pinch it closed. The preserves may ooze out a bit, but this is inevitable. Just try to keep in what you can.
• Roll the dough up very tightly into a long log. Cut the log into 12 or 16 cinnamon rolls. 12 for a large 9x13 pan or 16 for two round 8" baking pans (8 rolls in each). Grease your pan of choice extremely well and place cut rolls into prepared pan.
• At this point, if you are preparing these for the next day, wrap them TIGHTLY with saran wrap (you do not want any air to get in and dry out the dough) and refrigerate until you are ready. Remove from the refrigerator and set back into warm environment for the second rise.
• Allow them to rise in a warm place one more time until puffy, about thirty minutes.
• Once rolls have done their second rise. preheat the oven to 350°F and arrange the rack into the center of the oven. Bake cinnamon rolls for 20-25 minutes or until lightly golden on top.
• For the Cream Cheese Frosting
• Cream together the cream cheese and butter until light and fluffy. About 2 minutes. Add in vanilla
• Pour in the powdered sugar and mix until smooth. Taste and adjust if needed. Beat another 3 minutes on high until everything is very creamy.
• Once the rolls are done and removed from the oven, spread on a layer of frosting. Lots of it will just melt into the rolls. Once they have cooled a bit more, you can add a second, final layer of frosting.
