😦 At the weekend I like to spend my time to cook.

There are two problems here. First of all you are unlikely to spend anybody else’s time other than your own, so ‘my’ is redundant. Secondly, ‘spend time’ is much more commonly followed by _ing (gerund):

🙂 At the weekend I like to spend time cooking.

You can also use a preposition phrase to show where you spend time:

🙂 At the weekend I like to spend time in the kitchen.

And you can even combine these two examples:

🙂 At the weekend I like to spend time in the kitchen cooking.

Now spend some time practicing ‘spend time’!
