In a bowl, take the cinnamon sugar and add soft butter, flour and mix together. Then, add the milk slowly to get a dropping consistency. Finally, add the baking powder and mix well.
Take your muffin that you are going to bake, fill to half and bake in a pre-heated oven at 185 C for 15 to 20 mins.
Notes
The ones that were half filled got baked by 15 mins. Those that doomed, took 20 mins.
