To form the balls: Remove the dough from the bowl and pat it into an 8 inch square. Cut the square into 64 pieces. Roll each piece into a ball.
Roll the balls, one at a time, into the butter and then roll into the cinnamon sugar mixture. Place the sugar coated balls in the bundt pan, layering, staggering, and filling in the gaps as you go.
Once all dough balls have been dipped in the butter and sugar mixture and then placed into the bundt pan, COVER the bundt pan with plastic wrap and let rise for 45-60 minutes or until puffy. (The dough should rise and be just 1 inchesfrom the top).
Unwrap the bundt pan and bake at 350°F for 30-35 minutes or until bubbly and deep brown in color. Cool in the pan for 5 minutes(no longer!!!) then turn out onto a platter. Let cool for 10 minutes and then pour the glaze overtop.
To make the glaze: whisk the powdered sugar, milk, and a splash of vanilla in a large liquid measuring cup.
