Heat the milk in a small saucepan over medium heat until little bubbles begin to form around the outer edge. Remove from the heat and let stand until cooled to room temperature. Meanwhile, sprinkle the active dry yeast into the warm water in the mixing bowl of your stand mixer. Let stand for 5 minutes. It should become bubbly and foamy.
Add in the sugar, eggs and melted butter. Mix on low speed and then pour in the milk. Gradually mix in your flour and salt mixture on low speed, scraping down the sides of the bowl as needed, until everything is combined.
Turn your dough onto a lightly floured work surface and knead the dough for about 10 minutes, adding more flour if the dough is too sticky to work with. Grease a large bowl and place the dough into the bowl. Cover with plastic wrap and a kitchen towel (over the plastic wrap) and place in a warm spot until doubled in size, about 1 1/2 hours.
When your dough is about ready, prep your ingredients for the dough balls. Melt the butter and mix the sugar and cinnamon in a medium to large sized bowl. Lastly, spray your bundt pan with non-stick baking spray and set aside. Preheat oven to 350 F.
