How to Halve a Recipe (Including How to Halve an Egg)
To halve a recipe, divide every ingredient by two and use a smaller pan so the batter depth stays the same. Most measurements split easily — the only real puzzles are eggs and odd fractions. This guide gives you a halving chart, the exact way to halve an egg, what to do about pan sizes and bake times, and which recipes you shouldn’t halve at all.
The Quick Version
- Halve everything by two, then drop to a smaller pan.
- Halve an egg: beat one egg, use 2 tablespoons (it’s ~4 tbsp total).
- Odd fractions: convert to tablespoons first — half of ¾ cup is 6 tbsp.
- Bake time shrinks a bit; start checking early.
How to halve an egg
One large egg is about 4 tablespoons when beaten. So “half an egg” is 2 tablespoons of beaten egg. Crack one egg into a bowl, whisk it, measure out 2 tablespoons for your recipe, and refrigerate or scramble the rest. This is the single most useful trick in small-batch baking.
Halving chart for tricky amounts
| Original | Half |
|---|---|
| 1 cup | ½ cup |
| ¾ cup | 6 tbsp |
| ⅔ cup | ⅓ cup |
| ½ cup | ¼ cup |
| ⅓ cup | 2 tbsp + 2 tsp |
| ¼ cup | 2 tbsp |
| 1 tbsp | 1½ tsp |
| 1 tsp | ½ tsp |
| 1 large egg | 2 tbsp beaten egg |
Pan sizes and bake times
When you halve the batter, halve the pan so the depth stays similar — otherwise a thin layer bakes too fast and dries out. Good swaps: a 9×13 pan becomes an 8×8; a 12-cup muffin tin becomes 6 cups; a two-layer cake becomes one. Bake time usually shrinks 5–10 minutes, so start checking for doneness early and trust the toothpick over the clock.
Which recipes not to halve
Halving works for most cookies, brownies, quick breads and simple cakes. Be careful with recipes that hinge on precise chemistry or a single egg — delicate layer cakes, custards and some yeast breads can suffer when you split that one egg. In those cases, find a purpose-written small-batch recipe instead.
Frequently asked questions
How do you halve a recipe?
Divide every ingredient by two and use a smaller pan. Most measurements halve easily; the things to watch are eggs (use 2 tbsp beaten) and bake time, which shrinks a little.
How do you halve an egg?
Beat one egg and measure 2 tablespoons — half of a typical large egg (~4 tbsp). Save the rest.
What is half of ¾ cup?
6 tablespoons (⅜ cup). Since ¾ cup is 12 tablespoons, half is 6.
Which recipes should you not halve?
Delicate cakes, custards and some breads that depend on precise chemistry or a single egg. When in doubt, use a small-batch recipe instead.
