2.33x

Multiply all ingredients in your recipe by 2.33.

How to use this multiplier

Multiply everything: Take each ingredient amount and multiply it by the number shown. For example, if a recipe calls for 2 cups of flour and the multiplier is 1.5x, you'll need 3 cups.
Watch the baking time: The multiplier only applies to ingredients, not baking time or temperature. A larger, shallower pan will bake faster than a smaller, deeper one.
Eggs can be tricky: If your multiplier gives you 2.5 eggs, whisk 3 eggs together in a bowl, measure the total volume, and use half of it plus one whole egg.
