If you’ve ever bitten into a warm, gooey cookie and found a surprise centre oozing out, you’ve experienced the magic of stuffed cookies. And in Australia, they’re quickly becoming the ultimate sweet treat — with flavours that range from nostalgic to outrageously indulgent.

At Crumbaroo, we’re obsessed with creating the chunkiest, most flavour-loaded cookies possible. Here’s a look at our most popular stuffed cookie flavours (and why Aussies can’t get enough of them).

1. Nutella Stuffed Cookies – The All-Time Favourite

There’s a reason Nutella stuffed cookies top the list. The rich, hazelnut-chocolate centre melts into every bite, creating the perfect contrast between crisp edges and soft, gooey centres.

Try this if you love:

Classic choc chip with a twist
Ferrero Rocher vibes in cookie form
That ‘can’t-eat-just-one’ feeling

This one’s also available in our giant 1KG Birthday Cookie. Just saying.

2. Biscoff Stuffed Cookie – The Cult Classic

If you haven’t tried Biscoff in a cookie yet… prepare to be converted. This brown sugar cookie is stuffed with a molten centre of spiced, caramelised Biscoff spread — and it’s one of our most-loved creations.

Perfect for:

Gifting (it’s unique!)
Fans of caramel or cinnamon notes
People who want something different from plain choc chip

3. Mega Stuffed Oreos – Cookies Inside Cookies

What happens when you take a cookie, stuff it with more cookies, and bake it to gooey perfection? You get our Mega Stuffed Oreo — a chunky cookie with crushed Oreos, white and dark chocolate chips, and a soft Oreo cream centre.

Why it’s a fan favourite:

The texture: chewy, crunchy, creamy
That nostalgic Oreo hit
It looks as wild as it tastes

4. Peanut Butter Core – For the Salty-Sweet Addicts

We couldn’t leave out the peanut butter cookie. Our version is thick, soft, and stuffed with real peanut butter — the perfect balance to the sweetness of the dough.

Great for:

People who love Reese’s
Adults who “don’t like sweets” but secretly do
Late-night fridge raiders

Why Stuffed Cookies Are Different from Regular Cookies

Unlike thin or crisp cookies, chunky stuffed cookies are designed to be a full-on experience. Each one is a dessert on its own — handmade, baked fresh, and loaded with flavour in every bite.

You’re not just eating a cookie. You’re diving into a molten centre, exploring textures, and tasting something that actually feels homemade.
