Boterkoek (Dutch Butter Cake)
About this recipe
This recipe comes from a regional cooking tradition that draws on its own pantry, technique, and culinary history. The full editorial context for this cuisine is something we're still developing; the scaling and conversion tools above work the same regardless of origin.
As a dessert, Boterkoek (Dutch Butter 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.
Use the scaler above to set the number of servings you actually want to cook — quantities resize with culinary fractions, units promote sensibly (three teaspoons become a tablespoon), and the result reads like the recipe was written for your table.
Recipe data is sourced from TheMealDB's open community database; ScaleRecipe handles the curation, the scaling math, the editorial commentary, and the conversion utilities woven into each page.

Method
- Preheat the oven to 180°C/350˚F (conventional oven).
- Place the softened butter and sugar in the bowl of a stand mixer and whisk until creamy.
- Add the flour and salt and knead by hand until you have a smooth dough. Divide into two pieces.
- Line the base of a square or round cake tin with baking parchment (not a springform tin) and place the first half of the pastry on top. Flatten with your fingers and a spoon.
- Using a teaspoon, sprinkle dollops of dulce de leche over the base. Sprinkle with the chopped chocolate and cover with the second half of the pastry.
- This is a bit trickier, but if you don’t get it right, don’t worry, it’ll be fine once it’s baked! Brush the pastry with the beaten egg.
- Bake in the oven for about 30 minutes or until golden brown. It will be wobbly. That's because butter cake only firms up when it cools.
- Cut into small pieces when it has cooled completely!
- Notes
- Storing: Store in an airtight container outside of the fridge for about 2-3 days or in the fridge for 5 days. Freeze for up to three months.
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 Boterkoek (Dutch Butter Cake)
Boterkoek (Dutch Butter 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 Boterkoek (Dutch Butter 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 — Boterkoek (Dutch Butter 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 Boterkoek (Dutch Butter 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.
All-purpose flour
For gluten-free, a 1-to-1 gluten-free baking blend (one that contains xanthan gum) is the most reliable swap. For texture variations: bread flour gives chewier results; cake flour gives more tender. Avoid almond or oat flour as a 1:1 swap — they don't form gluten and most recipes structurally depend on it.
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 Boterkoek (Dutch Butter 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.
