I bought the Tassenküchlein just at the grocery store and tried the same. Instead of four tablespoons of milk I was a little more generous and took about five. Then the powder, stir into the cup and at 600 Watt 1 minute into the microwave. The consistency of the cake is about the the Hot Brownie a known fast-food chain. Even a liquid chocolate core there. Who a fluffy sponge cake awaits you here is wrong. For cold winter days I can imagine the cakes as a snack together with a cup of tea very good. Of course, tastes even better baked, but I'm quite happy with it and will buy it again.
