Baking ratios quick reference
Baking is less forgiving than cooking: scale the flour and you must scale the fat, liquid and leavening with it. These classic ratios are the skeletons behind hundreds of recipes — keep them intact and scaling stays safe.
Pound cake
1 : 1 : 1 : 1
flour : sugar : butter : eggs
The classic equal-parts cake — scale all four together and it holds.
Bread dough
5 : 3
flour : water (by weight)
About 60% hydration. Add ~2% salt and ~1% yeast by flour weight.
Pie crust (3-2-1)
3 : 2 : 1
flour : fat : water (by weight)
Works for sweet and savory crusts alike.
Cookies (drop)
3 : 2 : 1
flour : butter : sugar
Plus one egg per batch and leavening to taste.
Muffins (2-2-1-1)
2 : 2 : 1 : 1
flour : liquid : egg : butter
A forgiving baseline — fold in fruit or chips last.
Pasta dough
3 : 2
flour : egg (by weight)
Whole eggs weigh about 50 g each; adjust for flour humidity.
Pancakes (2-2-1-½)
2 : 2 : 1 : ½
flour : milk : egg : fat
Add ~2 tsp baking powder per cup of flour.
Roux
1 : 1
fat : flour (by weight)
Scale freely — thickening power follows the ratio, not the batch size.
Scaling notes that ratios don’t cover
- Leavening doesn’t always scale linearly. Past about double a recipe, baking powder/soda per cup of flour tends to need a slight pull-back — start at 90% of the mathematically scaled amount.
- Spices and salt scale less than linearly for large batches. Season toward the target, taste, and adjust.
- Pan geometry matters. The same batter in a different pan size changes thickness, and thickness changes time and temperature.
Put a ratio into practice with the recipe scaler — it keeps fractions readable while you scale.
