In a medium bowl, combine the warm milk, sugar, salt and oil.
Sprinkle the yeast on top and allow to activate. Mix in the yeast and make sure it's dissolved.
Add the flour to the wet ingredients and stir until combined. Cover and let sit for 30 minutes to rise.
Preheat an electric griddle or skillet to 300 degrees. Place mason jar rings on the pan, spray with pan spray and dust with cornmeal.
Scoop 6-7 tablespoons of dough into each ring. Place a sheet pan over the top of the griddle (not touching the rings.)
Cook for 5 minutes, sprinkle with cornmeal and then use tongs to flip. Cover again and cook for 5 more minutes until golden brown.
Remove the rings and cool on a wire rack.
Serve as is, or toasted with butter and jam!
