2-Minute Chocolate Protein Mug Cake (Grain-Free, Paleo)

Chocolate Protein Mug Cake

Does anyone get that feeling when you’ve finish dinner and just NEED something sweet? Some people tell me to reach for a square of dark chocolate and be done with it, but let’s be honest, that just won’t cut it for “dessert”. Last week, I wanted something extra chocolatey and super indulgent, and I was not willing to be patient while staring at my cake as it bakes in the oven, teasing me with every tick of the clock. It would also have to be gluten-free and dairy-free, ideally made from pure wholesome ingredients that wouldn’t give me an energy crash straight after… surely that couldn’t be too much to ask for?!

I considered making my Secret-Ingredient Chocolate Mousse or my Choc Chip Blondies which taste like heavenly squares of cookie dough, but eventually decided to come up with something entirely different…

The result: the most divine, single-serve mug cake, blissfully fluffy on the outside, but with a moist and gooey centre that literally melts on your tongue. It takes a couple of minutes to whip up from start to finish – if using a microwave – or 10 minutes with the oven version (which I personally prefer – worth the 8 extra minutes in my opinion!).

Not only is it gluten-free, but also completely grain-free (suitable for those following the Paleo diet) and comes complete with a vegan option if you sub the egg! It is high in fibre as well as healthy fats from the coconut flour and nut butter, and packs a nutritional punch from the cacao. It is also packed with protein thanks to a scoop of delicious chocolate protein powder.

In terms of protein powders, my personal favourite is Planet Paleo’s Organic Bone Broth Sports Protein, which comes in either Chocolate or Vanilla & Banana flavours. Both are delicious blended into a smoothie, stirred into porridge or used in baking, and bone broth contains easily digestible proteins such as collagen and gelatine, so is great for tissue repair and overall fitness. You can use the code ELI10 for a discount on Planet Paleo. I’m also a big fan of the protein powders by Nuzest (discount code: ELIB) and JS Health (discount code: UKEB15).

This is definitely one of my favourite chocolate recipes, alongside my Chocolate Peanut Butter Cup Milkshake, Raw Protein Brownies with Salted Caramel Frosting, and my Brain-Boosting Hot Chocolate.
