I was clicking around online a while back, and found this recipe.
I Googled, and it turns out these things have been quite popular – there are also recipes for Microwave Mug Brownies, which I think I’m going to try next!
I was really dubious of this recipe, just because – well – I’m not a huge fan of microwave cooking, and I’ve certainly never thought of making a cake this way, but I’m glad I tried it! It’s very chocolatey, and nice and easy to make – takes about 5 minutes including prep time.
The only difference I would make next time is to add about another 1/2 tbsp of oil – the cake was a tiny bit on the dry side, but with ice cream you can’t tell!
Ingredients
4 tbsp all-purpose flour
4 tbsp sugar
2 tbsp cocoa
1/2 tsp baking powder
1 egg
3 1/2 tbsp milk
1/2 tsp vanilla
1/2 tsp cinnamon
3tbsp vegetable oil
Method
Combine dry ingredients in a medium sized bowl
Add egg & mix well
Add vanilla, milk and oil
Spray oversized mug with baking spray and pour in the batter. It should reach just below halfway. If it’s any more, you will need to split the batter as it will overflow during cooking!
Microwave for 2 minutes 50 seconds (I use an 850W microwave, if yours is different you may need to adjust cooking times accordingly). Make sure you keep an eye on the cake throughout cooking.
When finished, let the cake cool in the cup for another couple of minutes before turning out, or if you like eat straight from the mug!
This recipe was enough for 2, so I turned the cake out of the mug and then sliced in half to make two portions. I also added some powdered sugar on top to make it look pretty
