Out of Eggs, one case

Can you substitute oil for eggs?

3 options, ranked, with the exact amount

Use thisBest of 3 options

Use Oil + water + baking powder

Per egg

1 ½ tbsp oil + 1 ½ tbsp water + 1 tsp baking powder

Not oil by itself, but a mix works in baking: 1 ½ tablespoons of oil, 1 ½ tablespoons of water and 1 teaspoon of baking powder replaces 1 egg. The oil stands in for the fat of the yolk, the water for the moisture and the baking powder for the lift. It does not bind, so it suits cakes and muffins better than cookies or patties.

Tips for substituting eggs

4 tips
  1. For 2 eggs: 3 tbsp oil, 3 tbsp water and 2 tsp baking powder.
  2. If the recipe already has plenty of baking powder, use ½ tsp per egg to avoid a soapy, metallic taste.
  3. Cool oil-and-water bakes completely before slicing; they are fragile warm.
  4. The reverse does not work either: eggs cannot replace the oil in a recipe one for one.

Questions

4 questions

How much oil replaces one egg?

1 ½ tablespoons of oil mixed with 1 ½ tablespoons of water and 1 teaspoon of baking powder.

Can I just add extra oil if I have no eggs?

No. Extra oil makes the bake greasy and it will not hold together. It needs water and leavening too, or a binder such as yogurt or flax.

Does the oil and water swap work in cookies?

Poorly. Cookies need a binder. Use a flax egg or 2 tablespoons of cornstarch whisked into 3 tablespoons of water.

Can I use melted butter in place of the oil?

Yes, the same 1 ½ tablespoons.
