R.A. Lucas is correct.

The object you get from require('express-handlebars') is not any 'plain old handlebars object'. It's a different object only used in express-handlebars

What you do is pass your helpers (and other settings as well) to the .create() function of that object.

Here's a fully functional example where I define 2 helpers in express-handlebars

var express = require('express');
var exphbs = require('express-handlebars');
var app = express();

//Here you can pass helpers that you would normally define in registerHelpers
//and you can also define stuff like `defaultLayout` and `partialsDir`
var hbs = exphbs.create({
    helpers: {
        sayHello: function () { alert("Hello World") },
        getStringifiedJson: function (value) {
            return JSON.stringify(value);
        }
    },
    defaultLayout: 'main',
    partialsDir: ['views/partials/']
});
app.engine('handlebars', hbs.engine);
app.set('view engine', 'handlebars');
app.set('views', path.join(__dirname, 'views'));
