Abstract: The invention relates to an aqueous binder liquid that can advantageously be used in the layer-by-layer production of 3-D sugar-based food products. More particularly, the invention relates to an aqueous binder liquid containing: (a) 50-70 wt. % water; (b) 12-30 wt. % sugar alcohol; (c) 5-20 wt. % short chain polyol selected from glycerol, propane-1, 2-diol and combinations thereof; and (d) 3-10 wt. % ethanol; wherein components (a), (b), (c) and (d) together constitute at least 90 wt. % of the aqueous binder liquid. The aqueous binder liquid of the present invention is particularly suitable for use in methods of layer-by-layer production of 3-D sugar-based food products in which the binder liquid is applied by means of piezo inkjet print heads. These methods enable the production of highly creative and complex patterns, such as cocktail toppers, edible logos and decorative wedding cake toppers.
