If you are using fresh mangoes (2 medium sized mangoes), wash, peel and dice the mangoes. Discard the pit (seeds) and chill the diced mangoes in the refrigerator or you may froze them too before using in the recipe. You may also use two cups of mango pulp instead of fresh mangoes if that is what you have.
Also add the milk, sugar and vanilla extract.
Blend until smooth.
Transfer the mango milkshake to glass cups, serve immediately for best results.
If serving later, you can save the milkshake in the refrigerator for about a day. If you want to store this for longer time, you may transfer the milkshake to ice cube trays, and freeze for longer time.
If you want to use mango pulp instead of fresh mangoes, you may slightly reduce the amount of mango pulp to make the milkshake.
