Dissolve yeast in a small bowl in warm water and set aside.
In a stand mixer with a dough hook, mix milk, sugar, salt, butter and egg. Add 2½ cups flour and mix thoroughly. Add warm yeast mixture and remaining flour, mix until blended, kneading with the dough hook for about 5 minutes. You may need to add a little more flour so the dough isn't sticky. Spray a large bowl with oil generously and place formed dough ball into bowl, cover and let rise until doubled in size, about 1 hour.
Punch down the dough and roll out on a lightly floured surface into a rectangle shape. Brush melted butter evenly over dough. In a small bowl, blend brown sugar and cinnamon and sprinkle evenly over dough. At the long edge, roll the dough into a long roll, pinching the edge (not ends) to seal the roll. Cut into 12 to 15 slices.
You can place rolls into a sealable container with wax paper in between to store in the freezer until later use. When you are ready to make waffles, remove the desired number of rolls and let thaw before placing onto the centre of a preheated greased waffle maker. Cook for approximately 10 minutes int the waffle or until the cinnamon roll waffle is golden brown.
Garnish with strawberries, syrup and confectioners (icing) sugar. Enjoy!
