Basic wheat-barley flour premixes were blended at ratios 70 : 30 and 50 : 50 (w/w), and white or dark types of wholemeal chia and teff replaced 5 or 10% of these bases. All non-traditional plant materials increased farinograph water absorption up to 10% in total, and with likely dilution of the dough gluten network, their addition increased the degree of dough softening up to twice. Physicomechanical properties of non-fermented dough were changing stepwise, mainly in terms of rising dough elasticity. Higher elasticity of wheat-barley dough was reflected in better both specific volume and spread ratio of cut-out cookies. Further recipe modification by wholemeal chia and teff flours enhanced these positive changes; cookie volumes based on the wheat-barley premix 50 : 50 were about 22% higher than their counterparts from the premix 70 : 30. For both attributes of cookie quality, somewhat higher values were observed for dark variants of wholemeal chia and teff. Moreover, the spread ratio of cookies containing teff types reached higher values compared to chia ones. Characteristic barley flour flavour could be less acceptable for common consumers; both wholemeal chia and teff flours were able to mask that by-taste.Keywords:
