Clicking button changes GUI Text

I have just gotten back into Unity and and am struggling to learn the new UI system. I have set up a button on my canvas but I cannot figure out how to manipulate text with the button. What I am trying to do: I want a GUI Text score to increase by 1 every time the button is clicked. Upon launch of the game the GUI text will say “Score: 0” and if the user presses the button once the GUI text will update to “Score: 1”. Thanks a bunch!

*Edit: I know how to code in a GUI box and change it with the button, but I would like to learn how to do it using the new text option in the canvas

You can use a simple script like this that you can call from the buttons “On Click” event

    int score = 0;

    public void AddToScrore()
    {
        score += 1;
        GetComponent<Text>().text = "Score: " + score;
    }
