ingredients

Self raising flour - if you do not have self raising flour, use all purpose flour and baking powder - ratio of 1 cup:1 tsp
Condensed milk
Oil - use a flavourless oil such as sunflower oil or vegetable oil. Coconut oil or canola oil work too.

Optional flavourings:

Vanilla extract
Handful of chocolate chips
Not quite a flavouring but rainbow sprinkles look so fun
To make a vegan mug cake, use dairy-free condensed milk

Hayley's Tips & Tricks

This is a ridiculously easy recipe but here are some tips to ensure you make the best mug cake ever!

Hayley's HACK - add the oil to your measuring instrument first before adding the condensed milk. This way, the condensed milk slips off easily.
Do not use olive oil - the flavour is too strong for a delicate cake
Do not over mix the batter as this produces extra gluten and you won't get a fluffy cake
Ensure you use a microwave safe mug
Do not fill the mug too full as the mug cake batter will rise
The batter will continue to cook after microwaving so do not be tempted to increase the microwave time too much
Timings will change based on the power of your microwave
The size of your mug will also alter the cook time - tall mugs take longer to cook and short and wide take less time.
For the best texture, enjoy immediately.

Serving suggestions

Here are some irresistible serving ideas for eggless mug cake. However you can definitely enjoy this perfect dessert just as it is! Great for Valentine's Day, Mother's Day, Father's day or any other special occasions.

Drizzle over caramel sauce or coconut syrup.
Top with fresh fruit such as strawberries, blueberries or chopped mangoes.
Top with a scoop of vanilla ice cream or whipped cream.
For a chocolate-y mug cake, I have poured warmed Nutella over the finished cake. Simply spoon the Nutella on the finished cake and let it soak through. I guarantee your cake will be even more moist and delicious!
This also works with warmed Biscoff spread then top with crumbled biscoff pieces.
