How to cook
Mix the flour with the baking soda, baking powder and sugar. Make a well in the middle and pour in the oil.
Dissolve the ammonium carbonate in the warm water and add it, along with the vanillas and cinnamon. Knead a smooth and soft dough that needs to rest for about 30 min.
Then roll it out into a thin crust and cut out shapes using cookie cutters or a glass. If you're going to be sticking them together, it's best to have an opening in 1/2 of them.
Arrange the cookies onto baking paper and put them to bake in a preheated 350°F (175 °C) oven until slightly pink. The ready cookies need to have a light color to them.
Afterwards, you can stick them together with diabetic jam if you like. Leave the cookies to sit for 2-3 days before serving, so they soften well.
