Parkin Cake
About this recipe
British cooking traditions favour generous root vegetables, slow-cooked meats, hearty puddings, and the kind of food that warms a damp island. The everyday repertoire prioritises preservation and shared family meals; the special-occasion repertoire (roast beef, Christmas pudding) is among the most globally recognised.
As a dessert, Parkin Cake is the part of cooking where ratio precision matters most: a five-percent miss on flour or sugar changes the texture in a way no savoury dish would notice. Weighing in grams beats measuring in cups every time.
Set your servings in the scaler above and every line of the recipe rewrites itself with smart fractions and unit promotion. Open Cook Mode to step through it hands-free with timers running.

Method
- Heat oven to 160C/140C fan/gas 3. Grease a deep 22cm/9in square cake tin and line with baking parchment. Beat the egg and milk together with a fork.
- Gently melt the syrup, treacle, sugar and butter together in a large pan until the sugar has dissolved. Remove from the heat. Mix together the oatmeal, flour and ginger and stir into the syrup mixture, followed by the egg and milk.
- Pour the mixture into the tin and bake for 50 mins - 1 hr until the cake feels firm and a little crusty on top. Cool in the tin then wrap in more parchment and foil and keep for 3-5 days before eating if you can – it’ll become softer and stickier the longer you leave it, up to 2 weeks.
Cooking notes
Baked goods are unforgiving with rounding — use weights rather than volumes whenever possible, and verify pan capacity if you scale up or down significantly.
For volume-to-weight conversions of any ingredient — flour, sugar, butter, salts — use the ingredient converter. To translate the recipe's oven temperature between °C, °F and gas mark, see the temperature converter.
When you scale this recipe up or down, remember that cooking time does not scale linearly. A doubled cake takes longer, but not twice as long; a doubled soup takes roughly twice as long. The cooking-time guide gives sensible starting estimates by dish geometry.
Scaling notes
Scaling Parkin Cake
Parkin Cake is written for around four servings as it stands on this page — scaling it up for a party or down for a meal-for-one is the small math problem most home cooks face every week. Here's how this particular dish responds to scaling, what changes linearly, and what doesn't.
Desserts are the most scaling-sensitive category, and Parkin Cake is no exception — the leavening, fat, and liquid ratios all interact. Doubling means a doubled pan AREA (not diameter), and bake time scales by the cube root of the volume change: a doubled cake takes about 26 % longer, not 100 %. Weigh ingredients in grams rather than measuring in cups for consistent results.
This recipe calls for eggs, which are the trickiest ingredient to scale to non-integer multiples. A US "large" egg weighs about 50 g; if a fractional scaling lands on, say, 1.5 eggs, beat one egg and weigh 25 g of the beaten mixture rather than guessing. The same goes for halving recipes — half an egg is 25 g of beaten egg, not a dramatic estimate.
Because this recipe is built around flour and sugar, weighing in grams (rather than measuring cups) is what separates a consistent bake from a one-time win. A cup of all-purpose flour can weigh 113 g or 150 g depending on how you scoop — that's a 30 % swing that ruins texture.

Beyond the recipe
Substitutions & make-ahead — Parkin Cake
Two things home cooks ask about most when they're outside the recipe's exact assumptions: what swaps work for which ingredients, and how the dish behaves when you make it ahead. Both depend on what Parkin Cake is doing structurally — here's the practical version.
Substitution ideas
Eggs
For binding (cookies, quick breads, meatballs): 1 large egg ≈ 1 tbsp ground flaxseed + 3 tbsp water, rested 5 minutes until gelled — structurally closest to a real egg. For moisture without structure (cakes, brownies): ¼ cup unsweetened applesauce or mashed banana per egg, accepting some loss of rise.
Butter
For sautéing or browning, equal-weight olive oil or a neutral oil works directly. For baking, equal-weight coconut oil (melted, then chilled to the same softness the recipe expects) gives a buttery richness; a quality vegan butter brick is the structural match for cookies and pastries where firmness matters.
Dairy milk
Unsweetened soy milk substitutes 1:1 in custards and baked goods (the protein content matches). Oat milk gives a creamier mouthfeel for soups and coffee drinks. Almond milk works for lighter applications. Skip coconut milk in savoury recipes unless the dish calls for it — the flavour is unmistakable.
For weight-based swaps and arbitrary quantities, the ingredient density converter and the cup-to-grams chart cover most pantry staples.
Make-ahead and storage
Most desserts in Parkin Cake's family can be made one day ahead, but storage matters more than for savoury dishes. Cakes and breads go in an airtight container at room temperature — refrigeration stales them faster than room air. Custards, cream-based fillings, and any dessert with eggs as a structural ingredient must refrigerate. For freezer storage, unfrosted cake layers wrap tightly and keep 2 months; frosted versions ice-crystal within 3-4 weeks.
