Baking Substitutions Chart
Out of buttermilk? No eggs? The 22 most-needed baking swaps with exact ratios — not guesses — plus live lookups below: find any substitution, scale it to your recipe’s amount, and pick the right egg substitute for the job. Ratios matter more than the swap itself: most substitution failures happen because the ratio was off, not because the substitute was wrong.

The full chart: 22 baking substitutions
Print it, screenshot it, tape it inside the cupboard door — this is the chart for the moment the shopping is done, the gifts are wrapped, and you discover you’re short one ingredient:
| If you’re missing | Amount | Substitute | Notes |
|---|---|---|---|
| Baking powder | 1 tsp | ¼ tsp baking soda + ½ tsp cream of tartar | Mix and bake immediately — single-acting. |
| Baking soda | ¼ tsp | 1 tsp baking powder | One-way without added acid; reduce any acidic liquid slightly. |
| Butter (melted) | 1 cup | ¾ cup vegetable oil | Oil is 100% fat vs butter’s ~80% — moister, denser crumb. Not for pastry. |
| Butter (any) | 1 cup | 1 cup coconut oil | Use refined coconut oil for neutral flavor. |
| Buttermilk | 1 cup | 1 cup milk + 1 tbsp lemon juice or white vinegar | Stir and rest 5 minutes until slightly curdled. |
| Buttermilk | 1 cup | 1 cup plain yogurt (not Greek) | Thin with a splash of milk if the batter runs thick. |
| Cake flour | 1 cup | ¾ cup + 2 tbsp all-purpose flour + 2 tbsp cornstarch | Sift together twice for an even blend. |
| Brown sugar (light) | 1 cup | 1 cup white sugar + 1 tbsp molasses | 2 tbsp molasses for dark brown sugar. |
| Heavy cream | 1 cup | ¾ cup whole milk + ¼ cup melted butter | Will not whip — cooking and baking only. |
| Sour cream | 1 cup | 1 cup plain Greek yogurt (full fat) | Nearly identical tang and thickness. |
| Cornstarch (thickening) | 1 tbsp | 2 tbsp all-purpose flour | Takes longer to thicken; whisk out lumps. |
| Egg (binding) | 1 egg | 1 tbsp ground flaxseed + 3 tbsp water | Rest 5 min until gelled. Best in cookies, brownies, muffins. |
| Egg (moisture) | 1 egg | ¼ cup unsweetened applesauce | Best in muffins and quick breads; over ½ cup total turns gummy. |
| Egg (lift) | 1 egg | 3 tbsp aquafaba (chickpea liquid), whipped | For meringues and light cakes; deflates fast — fold gently. |
| Vanilla extract | 1 tsp | ½ tsp almond extract | Stronger flavor — halve it or the almond takes over. |
| Half-and-half | 1 cup | ⅞ cup whole milk + 1½ tbsp melted butter | Whisk the butter in warm so it emulsifies. |
| Whole milk | 1 cup | 1 cup oat or soy milk | 1:1 swap for nearly all baking. |
| Honey | 1 cup | 1¼ cups sugar + ¼ cup liquid | Reduce another liquid slightly; browns faster — watch the oven. |
| Unsweetened chocolate | 1 oz | 3 tbsp cocoa powder + 1 tbsp butter | Reduce the recipe’s fat by ~1 tbsp if precision matters. |
| Self-rising flour | 1 cup | 1 cup all-purpose + 1½ tsp baking powder + ¼ tsp salt | Whisk dry ingredients together well. |
| Powdered sugar | 1 cup | 1 cup granulated sugar + 1 tsp cornstarch | Blend in small batches until powdery. |
| Cream of tartar | ¼ tsp | ½ tsp lemon juice | For stabilizing — not a leavening swap. |
| Molasses | 1 cup | 1 cup honey | Slightly milder flavor; 1:1 in most recipes. |

| Substitution finder | match(ingredient) → chart row | The exact swap for what you’re missing — e.g. buttermilk → 1 cup milk + 1 tbsp lemon juice. |
| Substitution scaler | chart ratio × amount | Each component of the swap multiplied by your recipe’s amount — 2 cups buttermilk → 2 cups milk + 2 tbsp lemon juice. |

When a substitution won’t work
Substitutions are safest where the ingredient plays a supporting role — flavor, moisture, or mild binding. They are riskiest where the ingredient does structural work: croissants and puff pastry need butter’s specific fat structure for lamination, meringues need real egg whites for their protein network, and angel-food cake needs the real thing, full stop. If the recipe’s name includes “laminated,” “meringue,” “soufflé,” or “choux,” treat any substitution as an experiment — and test a small batch first.
3 rules for clean swaps
- Match the ratio, not just the ingredient. A 1:1 swap where the correct ratio is 3:4 is the #1 way substitutions fail — butter to oil is ¾, not 1:1, because oil is 100% fat and butter is ~80%.
- Know the ingredient’s job. Eggs bind, moisten, or lift — pick the substitute for the job it’s doing in your recipe, not the one in the chart title. The egg picker above exists for exactly this.
- Expect a texture shift, not a failure. Oil-for-butter bakes come out moister and denser; applesauce-for-egg bakes come out softer. Different is not ruined — but if the occasion matters, bake a test batch.

Accuracy & limitations
Every ratio here is the standard kitchen reference, cross-checked across multiple 2026 sources — but baking is chemistry, and your flour’s protein content, your oven’s true temperature, and your altitude all move results. High-altitude bakers should also check our high-altitude baking calculator, because leavening and liquid behave differently above ~3,500 feet. Treat the chart as the starting ratio and your taste buds as the final judge.
Scaling the whole recipe too? The recipe scaling calculator handles that. For leavening-only swaps, see the leavening swap calculator.

Can I substitute oil for butter 1:1 in baking?
No — use ¾ the amount of oil (e.g. ¾ cup oil for 1 cup butter). Oil is 100% fat compared to butter’s ~80%, so a 1:1 swap makes bakes greasy. Oil works beautifully in muffins, quick breads, and cakes — moister, denser crumb — but not in pastry, croissants, or anything that relies on butter for lamination or structure.
What is the best egg substitute for baking?
It depends on the egg’s job. Binding (cookies, brownies): 1 tbsp ground flaxseed + 3 tbsp water, rested 5 minutes. Moisture (muffins, quick breads): ¼ cup unsweetened applesauce per egg. Lift (meringues, light cakes): 3 tbsp aquafaba, whipped. There is no single universal egg replacement — match the substitute to the role.
What can I use instead of buttermilk?
1 cup milk + 1 tbsp lemon juice or white vinegar — stir and let sit 5 minutes until slightly curdled. That’s the classic. The lazier version: 1 cup plain yogurt (thin with a splash of milk if the batter runs thick). Both give you the acidity that reacts with baking soda for lift.
Can I use all-purpose flour instead of cake flour?
Yes — for 1 cup of cake flour, use ¾ cup + 2 tbsp all-purpose flour plus 2 tbsp cornstarch, sifted together twice. The cornstarch lowers the effective protein, mimicking cake flour’s tenderness. It’s not identical, but it’s close in cakes and cupcakes.
When do baking substitutions fail?
When the missing ingredient does structural work. Laminated doughs need butter’s fat structure, meringues need real egg-white protein networks, and angel-food cake needs the real thing. Most other failures are ratio errors, not wrong substitutes — measure the swap, don’t eyeball it.
Can I swap white sugar for brown sugar?
Yes — 1 cup white sugar + 1 tbsp molasses makes light brown sugar (2 tbsp for dark). Going the other way, brown sugar works 1:1 for white in most recipes but adds moisture and a caramel note — fine in cookies, risky in delicate cakes.
