Classic British Parkin Biscuit Bars with Molasses and Ginger

For the best texture and flavor in your Parkin biscuit bars, soften your unsalted butter to room temperature. This ensures even melting when combined with golden syrup and black treacle or molasses, which provides the rich, deep molasses flavor essential to classic Parkin.

This recipe calls for medium oatmeal (rolled oats). If you prefer a finer texture, pulse your oats lightly in a food processor, taking care to preserve some chewiness. For gluten-free adaptations, use certified gluten-free oats and replace self-raising flour with a gluten-free self-raising blend containing baking powder.

If self-raising flour isn't available, use plain flour combined with 1 1/2 teaspoons baking powder, as indicated in the ingredients.

For egg-free or vegan alternatives, use a flax egg by mixing 1 tablespoon ground flaxseed with 3 tablespoons water and letting it sit until gelled, or use a commercial egg replacer; note texture may slightly vary.

Golden syrup is traditional but can be swapped with light corn syrup or honey, with minor flavor differences.

Use fresh, quality ground spices like ginger and mixed spice to maximize aroma and warmth; adjust ginger quantity to suit your taste.

These bars are nut-free and ideal for holiday comfort food. Store them in an airtight container once cooled to lock in moisture and intensify flavors over a day or two while maintaining their classic chewy texture.
