A method of preparing a flour based dough, includes mixing flour, a source of water-unextractable (WU) arabinoxylans, xylanase and water, wherein the source of WU arabinoxylans includes at least 10% WU arabinoxylans by weight of dry matter and the source of WU arabinoxylans is applied in an amount sufficient to deliver at least 2.5 g of WU arabinoxylans per kg of flour. The combined use of WU arabinoxylans and xylanase yields a dough product that exhibits improved processability, excellent proof stability and very high bake volume. Also disclosed is a flour based dough containing: 30-65 wt. % of flour of which at least 80 wt. % is wheat flour; 20-65 wt. % of water; at least 2.25% of WU arabinoxylans by weight of flour; and at least 5 units of xylanase activity per kg of flour, wherein the weight ratio of WU arabinoxylans to WE arabinoxylans exceeds 2.5:1.
