Christmas Cookie Recipe Scaler
Written by Mustapha B. · Updated August 13, 2026
Baking for a crowd this holiday? Paste your cookie recipe and scale it up (or down) with clean, cook-friendly fractions.
How to scale a recipe up or down
To resize a recipe, multiply every ingredient by the same factor: ½ to halve it, 2 to double it, 3 to triple it. Paste your ingredients above and this tool does the math for you, including the tricky fractions, so you get “1 ½ eggs” instead of “1.5 eggs”.
Tips for reliable results
- Eggs: for half an egg, beat one egg and use half by volume (about 1½ tbsp).
- Leaveners & salt: scale them too, but taste-sensitive items like spices can be adjusted to preference.
- Pans & time: a bigger batch needs a bigger pan; baking time changes with depth, not just volume. Check early with a skewer.
- Don’t over-scale: beyond 3–4× it’s usually better to bake in batches for even cooking.
