Tips for Halving Recipes
Eggs: For an odd number of eggs, beat the egg and use half by volume (about 2 tablespoons per large egg).
Baking powder & soda: Halve these as normal, but if a recipe uses both, they can be slightly reduced by 10% when halving as the chemical reaction is already slightly excessive in most recipes.
Pan size: Use a pan with roughly half the area. An 8-inch round pan has about half the area of a 9×13 inch pan.
Cooking time: Reduce by about 20–25% and check for doneness early. Smaller amounts cook faster.
Frequently Asked Questions
How do I halve ¾ cup?
¾ cup halved is 6 tablespoons. This is a common measurement that doesn't simplify to a standard cup fraction, so most recipes just say '6 tablespoons.'
Can I halve a yeast bread recipe?
Yes, but keep in mind that halving yeast dough recipes still requires a minimum yeast amount for proper leavening. We recommend not going below ½ teaspoon active dry yeast regardless of how much you scale down.
What is the hardest ingredient to halve?
Eggs are the most difficult since you can't easily cut a single egg in half. Beat the egg completely and measure out half — a standard large egg is about 3 tablespoons total.
