Cinnamon Roll Protein Loaf

Cinnamon is probably my favourite spice to use. It is so versatile and really lifts the flavour in your dishes and bakes. Who knows what I’d be without it now. I use it in everything from my gingerbread protein bars to buckwheat protein crepes.


This cinnamon roll loaf is perfect for when you’re craving the buns but are either short on time or want something a little quicker and more simple to bake. I always make loaf cakes as part of my weekly meal prep as they are perfect for either pimping your yoghurt bowls or taking to work for dessert. That’s if they even make it that far. In my hands, they’re consumed within seconds of removing from the tuppaware.


This particular cake is soft and has a slightly ‘healthier’ twist on the classic. Plus, it has the addition of protein for balanced macros. It is devilishly moreish and addictive. I can easily eat about 5 cinnamon roll protein slices in one sitting.
