In a small saucepan combine the 3/4 cup milk, 1/3 cup granulated sugar, 1/3 cup unsalted butter, 1 teaspoon salt. Heat over low heat until the mixture reaches 110°F (if mixture goes above 110℉, allow to cool until it reaches 110℉ again).
Combine the 1 (0.25 oz) pkg active dry yeast and warm water in a small bowl. Stir and allow to sit until bubbly.
Place the milk mixture into a large mixing bowl or the bowl of a stand mixer and add in 2 cups of the 4 to 4 1/2 cups all-purpose flour. Add in the yeast mixture and 2 eggs. Beat for 2 minutes, or until smooth. Add in the remaining flour to make a soft dough that does not stick to the sides of the bowl (you may not need the last 1/2 cup of the 4 to 4 1/2 cups all-purpose flour).
Turn out onto a floured surface and knead the dough until smooth and elastic, about 8-10 minutes. Alternately, knead the dough using the dough hook of a stand mixer for 2 minutes.
Shape the dough into a ball and placed in a greased bowl. Cover and allow to rise in a warm, but not hot, area until doubled in size, about 1 hour.
Punch the dough down and then turn out onto a floured surface. Divide the dough in 2 (*see tips below if shaping into one large tea ring) and roll each half into a rectangle about 13” by 9” in size.
Spread each rectangle with 1 T of the melted butter(2 Tablespoons unsalted butter, total) and half of the cinnamon sugar filling (3/4 cup granulated sugar, 2 teaspoons ground cinnamon total).
Roll up each rectangle horizontally and seal the edges. Shape each roll into a circle or ring on a lined baking sheet. Using kitchen shears or a sharp knife, cut 2/3 of the way into the roll at 1 1/2” - 2”intervals. Twist each cut section on its side, so the filling is facing up.
Cover and let rise in a warm, but not hot place until rings have doubled in size (about 1 hour).
Bake at 350℉ for 20-25 minutes or until the ring is golden on top.
Once Swedish tea rings are cool, combine the ingredients for the glaze(1 cup powdered sugar), adding enough of the water to make it a drizzling consistency. Drizzle over tea rings and serve when glaze has set.
