You can use applesauce instead of butter at a ratio of 1/2 cup of applesauce for every 1 cup of butter, in baking only. That is, you replace half the butter with applesauce and keep the other half as butter — or, if you want to remove all the butter, you replace the full amount at the same ratio and accept a denser, moister result. This is a fat-reduction swap, not a like-for-like fat swap: applesauce is not a fat at all, it is fruit puree, and it works by adding moisture and a little sweetness where the fat would have been. It is the swap to use when you want a lighter, lower-fat bake and are willing to trade some richness and structure for it.

Applesauce is the classic low-fat baking substitute, and it works best in the recipes where butter's job is mostly moisture: muffins, quick breads, brownies, spice cakes and banana bread. In those recipes, half the butter can be replaced with applesauce and the result is moist, tender and noticeably lower in fat and calories. A cup of butter has about 1,600 calories; a cup of applesauce has about 100. Replacing half the butter in a recipe saves hundreds of calories per batch, which is why this swap is a staple of light baking. What it cannot do is replace butter's structure, its ability to trap air, or its flavour — and this page explains exactly where that line falls.

The ratio, in a table

The table below converts butter to applesauce for the amounts you are most likely to meet. The rule is always the same: half as much applesauce as the butter you are replacing. The table shows the full-replacement amount — if you are replacing only half the butter, halve these numbers again and keep the rest as butter.

Butter called for Applesauce to use (full replacement) Notes
1 tablespoon 1 1/2 teaspoons
2 tablespoons 1 tablespoon
1/4 cup 2 tablespoons
1/3 cup 2 tablespoons + 2 teaspoons
1/2 cup 1/4 cup
2/3 cup 1/3 cup
3/4 cup 6 tablespoons
1 cup 1/2 cup
1 1/2 cups 3/4 cup
2 cups 1 cup

By weight, one cup of butter is 227 grams and half a cup of applesauce is about 128 grams (applesauce weighs 255 grams per cup). If you are weighing ingredients, that is the number to use. Note that applesauce is mostly water — about 85 percent — so you are adding moisture, not fat. That is why the result is moister but also denser: water does not tenderise crumb the way fat does, and it does not trap air the way creamed butter does.

Worked examples

Example 1: A lighter banana bread

A banana bread recipe calls for 1/2 cup of butter. Replace half of it — 1/4 cup of butter — with 2 tablespoons of applesauce, and keep the other 1/4 cup as butter. The bread will be moist and tender, with a slightly lighter crumb, and you will have saved about 200 calories across the loaf. The banana and the remaining butter carry the flavour, so nobody will notice the swap. This half-and-half approach is the best way to start with applesauce: you get most of the benefit with almost none of the risk.

Example 2: Low-fat brownies

A brownie recipe calls for 1 cup of butter. Replace it entirely with 1/2 cup of applesauce. The brownies will be fudgy and moist — brownies are one of the few recipes where a full applesauce replacement works well, because the chocolate and cocoa carry the flavour and the fudgy texture suits the extra moisture. Bake them for the same time, but check them five minutes early: the extra moisture can make the centre take longer to set, or, paradoxically, make the edges dry out while the centre is still wet. If the brownies are too dense, next time replace only half the butter.

Example 3: A spice cake with applesauce in the mix

A spice cake recipe calls for 3/4 cup of butter. Replace half of it — 3/8 cup of butter — with 3 tablespoons of applesauce, and keep the other 3/8 cup as butter. The applesauce's mild sweetness suits the cinnamon, nutmeg and ginger, and the cake will be moist for days. This is the recipe where the swap feels natural: applesauce belongs in a spice cake, and the flavour it adds is complementary rather than intrusive. Use unsweetened applesauce, or reduce the sugar in the recipe by a tablespoon per half cup of applesauce if you are using sweetened.

What changes in the result

Three things change when you swap applesauce for butter. First, the flavour: applesauce adds a mild, fruity sweetness. In spice cakes, banana bread, muffins and brownies, that sweetness is welcome; in a vanilla cake or a butter cookie, it tastes out of place. Second, the texture: the result is moister but denser, because water does not tenderise crumb the way fat does and does not trap air the way creamed butter does. A cake made with applesauce will be heavier and more compact than the butter version, and it may take longer to bake through. Third, the keeping quality: applesauce bakes stay moist for longer, which is an advantage for anything eaten over several days, but they can also become gummy if the recipe already has a lot of liquid.

The practical consequence is that applesauce is a good partial substitute and a risky full substitute. Replacing half the butter is safe in almost any muffin, quick bread or spice cake. Replacing all of it works only in recipes where the flavour is strong enough to carry the swap and the texture is meant to be dense and moist — brownies, banana bread, carrot cake. In a light sponge, a pastry or a cookie, a full replacement will fail.

When not to substitute

Do not use applesauce instead of butter in recipes that rely on creaming butter with sugar (sponge cakes, most layer cakes, many cookies), in pastry of any kind, or in shortbread, where butter is the structure and the flavour. Do not use it in frying or sautéing — applesauce is not a fat and will not fry anything. Do not use sweetened applesauce unless you reduce the sugar in the recipe, or the result will be too sweet. And do not use it in a recipe that is already very wet, such as a steamed pudding — the extra moisture will make it soggy. The swap is baking only, and even in baking it is a partial swap first and a full swap only in forgiving recipes.

One more caution: applesauce adds moisture, so baked goods made with it can take longer to cook through and can develop a gummy texture if underbaked. Always test with a skewer — it should come out clean or with a few moist crumbs, not wet batter — and let the bake cool completely before cutting, because the crumb sets as it cools.

Frequently asked questions

How much applesauce do I use instead of 1 cup of butter?

Use 1/2 cup of applesauce for 1 cup of butter — about 128 grams by weight. That is the full-replacement amount. For the safest result, replace only half the butter: use 1/4 cup of applesauce and keep 1/2 cup of butter. The half-and-half approach gives you most of the calorie saving with almost none of the texture risk.

Can I use applesauce instead of butter in cookies?

In soft, chewy cookies like oatmeal cookies, a half replacement works — the cookies will be softer and more cake-like. A full replacement makes cookies spread less, bake up soft and puffy, and taste of apple. In crisp cookies or shortbread, the swap fails: the cookies need butter's fat for their texture and flavour. For cookies, replace at most half the butter.

Should I use sweetened or unsweetened applesauce?

Unsweetened, always, unless the recipe was written for sweetened. Sweetened applesauce adds sugar you have not accounted for — about 20 grams of sugar per half cup — and the result will be too sweet and will brown faster. If you only have sweetened applesauce, reduce the sugar in the recipe by about a tablespoon per half cup of applesauce used.

Does applesauce make baked goods healthier?

It makes them lower in fat and calories, which is a genuine benefit: replacing a cup of butter (about 1,600 calories, mostly saturated fat) with half a cup of applesauce (about 50 calories) saves a lot. But the baked good is still a cake or a brownie, and the applesauce does not add fibre or nutrients in meaningful amounts. Think of it as a lighter version of the same treat, not a health food.

Can I use applesauce instead of butter in brownies?

Yes — brownies are one of the best recipes for a full applesauce replacement. Use 1/2 cup of applesauce for 1 cup of butter. The brownies will be fudgy and moist, and the chocolate will carry the flavour. Check them five minutes early, because the extra moisture changes the baking time, and let them cool completely before cutting.

Can I use applesauce instead of oil as well?

Yes. Applesauce replaces oil at a 1:1 ratio in baking — 1/2 cup of applesauce for 1/2 cup of oil — because oil and applesauce are both liquid additions, and the volume matters more than the fat content. The same limits apply: it works in muffins, quick breads and brownies, and fails in pastry and anything that needs creaming.
