Turn on the oven at 175 degrees Celcius, convectional heat.
Melt the butter in a pan. Then take it off the heat.
150 g butter
Mix the oatmeal, sugar, vanilla, baking powder and flour in a bowl and add the eggs and the melted butter. Stir the dough together with a spoon until it is smooth.
250 g oatmeal, 250 g sugar, 1 tsp vanilla paste, 2 tsp baking powder, 2 tbsp all purpose flour, 2 eggs
If the dough feels very wet, you can leave it for 15 minutes before moving on, and the oatmeal will absorb some of the liquid.
Make balls of the dough, about 1 tbsp. dough per ball. Place them well apart on a baking sheet and press them slightly flat with a spoon or the palm of your hand. You can fit 8 balls on a regular baking sheet.
Bake the oatmeal cookies at 175 degrees Celcius with convectional heat for 8-10 minutes or until the edges are brown.
Allow the cookies to cool slightly on the baking sheet before moving them to a wire rack where they must cool completely.
