Quick Microwave Molten Chocolate Cake in a Cup/Mug – it works

June 4, 2015 Published by Dina 4 Comments

I saw this microwave molten chocolate cake in a mug online and was intrigued by it. The recipe on these sites is identical so I am not sure where the original comes from. I made it once and had to tweak it just a bit the second time.

  • To bake this in one cup use a 16 oz cup with a wide mouth. Note that this produced a rather large serving so unless you are really hungry for chocolate cake, I suggest baking it in two 8 oz cups.
  • I reduced the 2 minute cooking time the original recipe called for. Two minutes cooked the cake right through, it was still good but had the texture of a brownie without a molten center. When I baked it in a one large cup it took 70 seconds in my microwave to retain the soft center. When I baked the cake in a smaller 8 oz cup 45 seconds was enough (I cooked each cup separately).
  • The cake should just begin to pull away from the sides of the mug when it’s done. Don’t overcook it.
  • I added a little baking powder and a tablespoon of hot tap water to lighten the batter up a bit.
  • Instead of mixing the chocolate into the batter I spooned it on top of the batter in the the mug before baking and it sank into place as it cooked.
  • If you bake it in two separate cups mix the batter in a separate glass dish and then pour it into the two 8 oz cups.
  • The cake will rise to the top of the cup as it cooks and will then sink slightly.

 

You can prepare the batter a few hours in advance and keep refrigerated but bake it only at the last minute. If you bake it cold it may take a few extra seconds to cook. The cake rises to the top of the mug and leaves chocolate footprints as it settles. You can wipe the inside rim of the mug with a wet paper towel for a cleaner presentation.

      Hi Pragati, always nice to hear from you, thanks for the comment. I had to make it a couple of time before I was happy with the results. It was mostly the length of cooking time and the size of the dessert. In two smaller cups and 45 seconds in the microwave it makes a perfect (2) serving. I am sure that without a microwave you can bake it in the oven, it will just take longer.
