Blend avocados, yogurt and condensed milk until smooth. You may want to consider reducing the condensed milk if it's too sweet. I found that when I tasted it before it was chilled, it wasn't too sweet. But it got sweeter while setting. I might reduce the condensed milk slightly next time. Pour batter into crust and smooth top with spatula. Chill in fridge overnight. Keep in fridge until just before serving.
