Instead of ordinary wheat flour, the recipe uses ground almonds and fine polenta. The ground almonds make the squares lovely and moist while the polenta adds a slight crunch. You can buy polenta in most supermarkets.

Xylitol is a natural sweetener made from birch sap. It has fewer calories than sugar and it’s tooth-friendly, too. You can buy it in health food shops as well as large supermarkets where it’s usually sitting on the same aisle as ordinary sugar and other sweeteners.
