Unless you’ve been living under a rock for the past year, you’ve probably heard of the beltsander brownie by now.

If not, here’s a quick explanation…

It’s basically a protein brownie, but what makes it special is that is EASY!

Yes! Easy with a capital E — it’s that quick and simple to make.

As for the name, that comes from @the_beltsander (Instagram) who’s widely acknowledged as the brains behind this recipe. As with all good products however, the name has now become a term for all simple protein brownies — joining the likes of biro, hoover and sellotape!

What makes this version so special is that it uses just four ingredients and it takes just a couple of minutes to make.

Anyway, I’m sure you’re keen to get baking, especially since it’s faster to make them than this is to read!
