Check the role of malt syrup in your recipe: sweetness + chew (cookies/bars) or color/shine (glazes/breads).
Start with the closest texture swap: use 1:1 golden syrup or light corn syrup for viscosity and glossy results.
If using sweeter syrups (honey/maple), begin with 25% less than the malt syrup amount, then taste-adjust the final batter.
If your substitute is thinner (honey) or you want extra chew, reduce the recipe’s added liquid slightly or chill batter 10–15 minutes before baking.
For molasses, use it only if the flavor won’t clash—choose light/mild and reduce quantity if it tastes too intense.
