About this recipe
Canadian home cooking reflects regional traditions across a huge geography — Quebec's French legacy (tourtière, poutine), the British baking of the Maritimes, the Indigenous and Asian-influenced cuisines of the West Coast.
As a dessert, Jam jam cookies 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.
The scaler above resizes every ingredient to the number of servings you actually want; Cook Mode walks you through the recipe one step at a time with hands-free timers.

Method
- Preheat the oven to 350 °F (180 °C) and line a large baking sheet with parchment paper.
- In a stand mixer with the paddle attachment, cream the butter, white sugar and egg until combined, then add the molasses and vanilla and mix until smooth.
- Once combined, add the baking soda water mixture and mix for another minute to combine.
- Combine dry ingredients; mix baking powder, cinnamon, flour and salt in a separate bowl then add to the wet ingredients a little at a time, mixing on low until fully combined and scraping down the sides to ensure everything is incorporated. The dough should be easily shaped.
- Portion dough with a small spoon, roll them into balls and place them on the lined cookie sheet, press them into flat discs using a floured glass or your moistened palm.
- Place cookies on parchment-lined baking sheets and bake for 10-12 mins. Remove from the oven and let them cool for at least 10 minutes.
- Once cooled the cookie sandwiches by spreading at least two teaspoons of your favourite jam between the two cookies. Repeat and enjoy with a cup of tea.
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 Jam jam cookies
Jam jam cookies 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 Jam jam cookies 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 — Jam jam cookies
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 Jam jam cookies 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.
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 Jam jam cookies'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.
