Ingredients
- Gluten Free flour - This can either be gluten free plain or self-raising flour. If you don’t want to make this gluten free - look at my substitutes list below.

- See recipe card for quantities.
Instructions
- Begin by lining your heat proof dish with greaseproof/parchment paper.
- Next melt the butter for 30 secs then add the cocoa powder and sugar and mix until combined.
- Mix in the egg, then fold in the flour and chocolate chips.

4. Pour into your prepared dish and bake for 4 mins in the microwave, making sure to stop it every minute to prevent it from overflowing.

5. Allow it cool for 5 mins. In the meantime, combine the chocolate and milk and microwave for 30second intervals until melted and mix until smooth.

Equipment
Equipment can have a big impact on how a recipe turns out. Stone bakeware takes longer to heat up than metal pans, and also retains heat for longer, which could make the recipe more watery, or burnt on the outsides.
For this recipe you’ll need a heat proof glass/ceramic dish, this is the one I use [link] and I use it all the time, which I line with greaseproof/parchment paper so you can easily remove it from the dish.
Storage
Storing and freezing cake
How long does microwave cake last?
This will stay good at room temperature for up to 5 days, and in the freezer for up to 2 months if stored in an airtight container.
Top tip - Microwave cake baking
Although this microwave cake mug recipe is super simple to make, here are just a few expert tips I'd recommend:
Don’t fill your baking dish too much/high as this cake does rise! And may overflow out of your dish if filled to the top.
Make sure to stop the microwave every 3 minutes to prevent the cake from overflowing, even if you haven’t filled your baking dish to the top it may still overflow, if left to bake in the microwave for too long.
Allow the small dairy free chocolate cake to cool for at least 20 mins before adding the ganache, so it maintains its shape and remains thick, as adding it to a hot cake will make the ganache more runny.
