Canadian Butter Tarts
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, Canadian Butter Tarts 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 fan 170C/ conventional 190C/gas 5. Roll out the pastry on a lightly floured surface so it’s slightly thinner than straight from the pack. Then cut out 18-20 rounds with a 7.5cm fluted cutter, re-rolling the trimmings. Use the rounds to line two deep 12-hole tart tins (not muffin tins). If you only have a regular-sized, 12-hole tart tin you will be able to make a few more slightly shallower tarts.
- Beat the eggs in a large bowl and combine with the rest of the ingredients except the walnuts. Tip this mixture into a pan and stir continuously for 3-4 minutes until the butter melts, and the mixture bubbles and starts to thicken. It should be thick enough to coat the back of a wooden spoon. Don’t overcook, and be sure to stir all the time as the mixture can easily burn. Remove from the heat and stir in the nuts.
- Spoon the filling into the unbaked tart shells so it’s level with the pastry. Bake for 15-18 minutes until set and pale golden. Leave in the tin to cool for a few minutes before lifting out on to a wire rack. Serve warm or cold.
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 Canadian Butter Tarts
Canadian Butter Tarts 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 Canadian Butter Tarts 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.
Butter is one of the easier ingredients to scale because it's sold in standardised sticks: 1 US stick = 8 tablespoons = ½ cup = 113 g. Any fractional scaling lines up neatly on a kitchen scale, and grocery-store butter packaging is already pre-marked in tablespoon increments along the wrapper.

Beyond the recipe
Substitutions & make-ahead — Canadian Butter Tarts
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 Canadian Butter Tarts 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.
Tree nuts
Walnuts ↔ pecans (similar oil content and bite); almonds ↔ hazelnuts (firmer texture). For nut-free, toasted pumpkin seeds, sunflower seeds, or roasted chickpeas give similar crunch and a less rich flavour profile.
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 Canadian Butter Tarts'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.
