Baking is so easy! Eggs, butter, sugar and flour are all the ingredients you need for baking cakes or cookies. If you use more eggs and less flour it will become a sponge mixture. With less eggs and more flour you will get a dough for crispy cookies. Cakes and cookies should surprise, enchant, inspire and especially succeed and we at RBV Birkmann develop cookie cutters and baking moulds for this purposes.
