Honey (Best Option)
3/4 tablespoon per 1 tablespoon brown sugarHoney contains fructose and glucose, which provide sweetness and moisture similar to brown sugar's sucrose and molasses content. This helps maintain the meatloaf’s tenderness and caramelization during baking.
To avoid excessive stickiness or browning, reduce other liquids slightly and monitor baking time closely. Honey’s liquid form means you may want to reduce other wet ingredients marginally.
The final meatloaf will be moist with a subtle floral sweetness, closely mimicking the original brown sugar effect but with a slightly different flavor profile.
