I followed this recipe to make condensed milk but it never thickens.

2 cups milk
1/2 cup sugar
25 gr butter

I tried it once following the recipe to a T, and when it didn't thicken not even a little bit after 30 minutes, I decided to halve the recipe and use a big frying pan so that it would thicken faster. It didn't thicken, again. It never thickens and the consistency is exactly like the milk itself.

I mix sugar with milk, then on medium heat constantly stir. After about 20-25 minutes, half of the milk was evaporated but the thing didn't thicken! What am I doing wrong?

This Nutrition Facts table for sweetened condensed milk lists 166g of sugar per cup.
Perhaps some of that comes from the naturally occurring lactose in the milk, but probably not a significant amount compared to the added sugar.

You're only putting about 100g of sugar in to your mix and then reducing the volume by half.
So you're probably starting off with a little over 2 cups, and reducing it down to a little over 1 cup, but you're still left with substantially less sugar in that 1 cup of reduced product - probably only a little over half the amount indicated above.

I suggest increasing the amount of sugar to at least 3/4 cup.

You said 20-25 minutes, this is way too short.

When you are reducing milk, you have to use a really low temperature to avoid caramelization. It shouldn't even be simmering. You have to watch it to know when it's done, but the correct time should be in the range of 6 to 12 hours.

It will be a bit fiddly to get it to work without accidental browning (or worse, scorching) but with enough oversight, the end product should be acceptable.

If I need a thicker consistency I would add some skimmed milk.
