Ingredient Substitution Finder
Out of one ingredient? Here's what to reach for instead, and the ratio that actually works.
Dairy
| Need | Use instead | Ratio |
|---|---|---|
| Buttermilk | Milk + lemon juice or vinegar | 1 cup milk + 1 tbsp acid, rest 5 min |
| Heavy cream (for whipping) | No true swap | Chilled full-fat coconut cream can whip, 1:1 |
| Heavy cream (for cooking/baking) | Milk + melted butter | 3/4 cup milk + 1/4 cup butter per 1 cup cream |
| Sour cream | Plain Greek yogurt | 1:1 |
| Whole milk | Skim milk + melted butter | 1 cup skim milk + 1 tbsp butter |
Sweeteners
| Need | Use instead | Ratio |
|---|---|---|
| Brown sugar | Granulated sugar + molasses | 1 cup sugar + 1 tbsp molasses |
| Powdered (confectioners') sugar | Granulated sugar + cornstarch, blended fine | 1 cup sugar + 1 tbsp cornstarch, blend until powdery |
| Granulated sugar (for honey in a recipe) | Honey | 3/4 cup honey + reduce other liquid by 1/4 cup, per 1 cup sugar |
Flour & Leaveners
| Need | Use instead | Ratio |
|---|---|---|
| Cake flour | All-purpose flour + cornstarch | Per 1 cup: remove 2 tbsp flour, add 2 tbsp cornstarch |
| Self-rising flour | All-purpose flour + baking powder + salt | 1 cup flour + 1½ tsp baking powder + ¼ tsp salt |
| Baking powder | Baking soda + cream of tartar | 1 tsp baking powder = ¼ tsp soda + ½ tsp cream of tartar |
| Baking soda | Baking powder | Use about 3× the amount of baking soda called for |
Acids & Misc
| Need | Use instead | Ratio |
|---|---|---|
| White vinegar | Lemon juice | 1:1 |
| Cornstarch (as a thickener) | All-purpose flour | Use 2× the amount of flour vs. cornstarch called for |
| Vanilla extract | Vanilla bean paste | 1:1 |
Ratios here are starting points, not guarantees
Every substitution changes something about the final result — texture, browning, tang, or structure — even when the ratio is right. These are the standard, widely used swaps, but a recipe that leans heavily on the exact ingredient (a delicate cake relying on cake flour's low protein, for instance) will show a substitution's effects more than a forgiving one will.
Egg, butter, herb, and spice substitutions get their own tools
If you need an egg size conversion, a butter-to-oil swap, a fresh-to-dried herb conversion, or a whole-to-ground spice conversion, those have dedicated calculators elsewhere on this site with more detail than fits in a single row here.
When there's genuinely no good substitute
A few ingredients don't have a substitute that behaves the same way — true heavy cream's ability to whip into stable peaks is hard to replicate, and some substitutions (like baking soda for baking powder) only work if the recipe already has enough acid for the soda to react with. When in doubt, it's often worth making a shopping list instead of forcing a swap on a recipe you care about getting right.
