Mix all ingredients into a thick dough (attention: the dough is very tough due to the corn starch and tends to move upwards when stirred with the mixer).
Either leave the mixture as it is or add any ingredients such as fruit, etc. and mix together again.
Divide the dough between the muffin molds and bake in the preheated oven (180 ° C) for about 20 to 25 minutes.
