When the dough has risen, punch it down and pour it back onto a lightly floured or otherwise non stick surface. Roll the dough out with a rolling pin into a rectangle ( I recommend about 12 inches by 18 inches). Dough should be very thin when rolled.
Sprinkle the cinnamon and brown sugar onto the surface of the dough. The smear on the cream cheese, followed by the strawberry preserves on top of that.
Roll dough with hands, starting at the long end until completely rolled into a long tube. The dough will be stretchy, so when you get to the end, stretch the edge around and make sure it is on the bottom, under the entire roll so that when it bake, it will not unravel.
Shape tube into a circle, connecting both ends. You should end up with basically a giant donut shape.
Bake at 350°F for 30 minutes.
While the cake is baking, prepare the icing. Combine sifted powdered sugar, milk, and vanilla.
When cake is finished baking, let cool completely, about 1 hour. Pour frosting over the top and smear over the top. Coat with sugar sprinkles, preferably purple, green and gold!
Cut and enjoy!
You may notice that the color of the preserves did not retain. Depending on original thickness of filling, it may not be noticeable when you cut into it. Rest assured, the flavor is absolutely there!
