A quick, easy and delicious melt in the mouth chocolate vegan mug cake, easy to make gluten-free. The perfect chocoholics treat.

This Chocolate Vegan Mug Cake recipe is maybe more for the Mums, teens or anyone who needs an emergency quick sweet chocolate fix – think PJs, grey afternoons, hormonal wobbles and snuggling under blankets on the sofa.

Think warm chocolate cake, made in minutes with melted chocolate chunks, topped with your favourite ice cream and a sprinkling of crushed walnuts.

The Chocolate Vegan Mug cake can also be made gluten-free – if you switch the plain flour for gluten-free plain flour.

What kind of mug to use for the chocolate vegan mug cake?

Make sure it’s a microwave-safe mug and that the plate that goes underneath is also safe to use in the microwave. We’ve used a wider rimmed shorter mug, but any will work.

Chocolate Mug Cake Serving Suggestions

So many options, the chocolate mug cake is lovely on its own, but we completely understand if like us you feel the need to add a drizzle of vegan cream or add any of these…

Ice cream – vanilla or salted caramel work particularly well

Whipped cream, we used Oatly whippable

Caramel sauce – trust us this works, also really good along with the ice cream

Custard – for ease we use the Coconut Collaborative

Easter toppings – whipped vegan cream and topped with crunched up vegan mini eggs

Festive options – whipped cream with some crushed gingerbread


How to make the Chocolate Vegan Mug Cake gluten-free

To make the chocolate mug cake gluten-free switch the flour to gluten-free plain flour. We use the FREEE (Doves Farm) gluten-free plain flour blend that you can find in supermarkets down the free-from aisle.

We’ve also used a touch of baking powder. This recipe does not need xanthan gum.


Which chocolate to use?

We like to bake with dark chocolate, it’s smoother and handles heat better than many vegan milk chocolates. Use at least 70% cocoa solids up to 85% cocoa solids.

Which plant-based milk to use?

We love to bake with unsweetened oat milk, but unsweetened almond milk will work just as well too.


We’ve reduced the sugar a little

This works for our taste buds; the chocolate mug cake is sweet enough once combined with the sugar and the chocolate – especially if you top it with ice cream or custard! But if you have a particularly sweet tooth then use 2 tbsp of golden caster sugar.
