Looking for a quick, cozy treat that fits your dietary needs? This vegan allergy-friendly coffee flavoured cake in a ramekin is soft, packed full of coffee flavour, and made just for one—perfect for when you want something sweet without a whole tray of leftovers. It's easy to make, totally plant-based, and free from the top 8 allergens (if using gluten-free flour add a tiny pinch of xantham gum). Best of all, it's baked and served in the same ramekin!

There's something deeply comforting about coffee flavoured cake—it's like first thing in the morning in cake form! Also the aroma that fills the kitchen is so wonderfully uplifting and comforting. At the same time, coffee cake isn't for everyone, it's a little 'grown-up' in flavour and i've come across some people who know it just isn't for them. That's where this single serve coffee cake fits in - not only can you satisfy your coffee cake craving in a few minutes and just a ramekin to hand, but despite being dairy, egg and nut-free, this cake is just as delicious as any you may have come across before.

I've made my version nut-free, but if you like nuts walnuts would be the perfect addition. Why not add 3, roughly crushed to the batter for a proper traditional coffee and walnut cake version?

Leave to cool. (At this point, if you have some coffee left it's nice to drizzle 1 tsp over the sponge to give extra flavour and keep the sponge nice and moist.)
