PRINTABLE BAKING REFERENCE
Recipe-halving card
Halve ingredient quantities while keeping the recipe's units. Use this card for common measures, then review the whole list before baking.
Content disclosure: Prepared with AI assistance. The examples explain arithmetic and measuring assumptions; no physical baking test is claimed.

Common quantities divided by two
The cup-and-spoon combinations below assume 1 cup = 16 tablespoons and 1 tablespoon = 3 teaspoons, as in US customary measures. Do not use those combinations with a 20 ml Australian tablespoon. Weight and same-unit halving work without a cup conversion.
| Original | Half |
|---|---|
| 1 cup | 1/2 cup |
| 3/4 cup | 3/8 cup (1/4 cup + 2 tbsp) |
| 2/3 cup | 1/3 cup |
| 1/2 cup | 1/4 cup |
| 1/3 cup | 1/6 cup (2 tbsp + 2 tsp) |
| 1/4 cup | 2 tbsp |
| 1 tbsp | 1 1/2 tsp |
| 1 tsp | 1/2 tsp |
| 3/4 tsp | 3/8 tsp (1/4 tsp + 1/8 tsp) |
| 1/2 tsp | 1/4 tsp |
| 250 g | 125 g |
| 100 ml | 50 ml |
| 3 eggs | 1 1/2 eggs: portion by weight |
A small batch example
A recipe with 200 g flour, 150 g sugar, 100 g butter and 3 eggs becomes 100 g flour, 75 g sugar, 50 g butter and 1½ eggs. Whisk the eggs, weigh the mixture without the shell, then use half that weight. The portion comes from your actual eggs; this card does not assume every egg weighs the same.
What to keep and what to review
- Keep the oven temperature and method instructions. Half a batch does not mean half the baking time.
- Use an appropriate pan for the intended batter depth. Compare pan areas before swapping pans.
- For “2 cans, 400 g each”, half is one 400 g can. The package size stays 400 g.
- For “1 cup (120 g) flour”, choose one measure and halve it, or deliberately update both: ½ cup (60 g). The recipe scaler flags dual measures for review.
- For very small quantities, use suitable measuring equipment; do not round a nonzero ingredient to zero by accident.
