Magic Minute Microwave Mug Cake


by: Why Is There Air?

This recipe is my guilty pleasure, a treat I make myself on gray afternoons like today or when ThermoHubby John is away on business. Kind of like Nigella Lawson in her bathrobe peeking into her refrigerator at midnight ;-) I guess I’ve been good lately as I haven’t made this Magic Minute Microwave Mug Cake in quite a while. Today I’ve made up for it – in my biggest mug, no less – and I’m delighted to share it with you here.

1.  Put the lid or a plate on your Thermomix bowl, press the weighing scales button, let it settle to 0 and place your egg on top. Note the weight. Crack your egg into the bowl, and then add the “egg weight” of flour, sugar and butter. (I.e., if your egg weighs 60 g, use 60 g each of the other three ingredients. If your egg weighs 55 g, use 55 g of the other ingredients, etc.) Add a pinch of salt if required. Mix 30 seconds/Speed 5. Scrape the sides of your TM bowl with the spatula and mix again 30 seconds/Speed 5.

2.  Scrape the batter into a greased, microwaveable mug that is big enough to allow for expansion of the batter (or you’ll have a sweet molten volcano on your hands!) and “bake” in the microwave 1 minute at 1000W / 1 minute 45 seconds on 750W or 800W or until the cake springs back when touched (be careful – it’s hot!). Actual bake time will depend on the weight of your egg (the amount of batter you make), the size and thickness of your mug and the power of your microwave so you’ll need to exercise a bit of happy cook’s judgement.
