1 ripe avocado
1 cup of ice(crushed ice is preferred for easier blending, but not necessary)
1/2 cup milk(feel free to substitute fat free, 1-2% milk, soy, almond or even coconut milk, but that might be too rich)
1/3 cup of sweetened condense milk(can be adjusted for more or less depending on how sweet you like your shake, can even use honey, agave,sugar, or simple syrup, but these have to be adjusted as well since some can be too sweet if use the same amount as the listed recipe amount for condense milk)
Blend till smooth and enjoy this tasty summer treat. But just don't have it too often, unless you want your waistline to expand
Note: First time I had this was at my local Pho(Vietnamese) restaurant, it didn't look very good in the picture on the menu, but was ever so good. They also had a durian shake that was also very good, but that's for next time.
