Really really excellent, not-too-sweet frosting! I agree that it is a little bit time consuming as it takes me a while to slowly thicken the milk and flour but it's worth it in the end.... and this frosting pipes well too! Everyone I've ever made it for loves it :)
I added a little bit of almond extract to it...yummy :)
A little time consuming at the stovetop, but it hasn't stopped me from making it again and again. Very light and not too sweet, just as said. A favorite for all who sample!
