Mayonnaise Dressing

Lighter commercial mayo-style dressing; 1:1 swap in sandwiches and salads, slightly sweeter

mayonnaise substitute
for baking.
Mayonnaise pulls a strange double-shift in baked goods: its 70-80% oil acts as the fat that coats flour proteins to limit gluten, while its egg-yolk lecithin is a built-in emulsifier that keeps batters tender at 350°F. That's why a chocolate cake using 1 cup of mayo bakes denser and moister than the same recipe with 1 cup of butter — no creaming step, no air, just a closed crumb that stays soft for three days. This page ranks swaps by oil-and-emulsifier coverage first, structural impact second.

adjustment for baking
Swap 1:1 by cup; the lighter dressing has 35-50% oil versus mayo's 70%, so cakes lose roughly 25% of their fat-coated gluten suppression and bake a touch chewier. Add 2 tablespoons of neutral oil per cup to recover the closed-crumb texture. Sweetener bumps sugar by about 5%.

Cream Cheese
7.5best for baking1 cup : 1 cup
Soften to room temperature; richer and tangier, works in dips and chicken salads
7.5
adjustment for baking
1:1 by volume after softening to 70°F so it blends without lumps. Cream cheese is 33% fat versus mayo's 70%, so reduce flour by 2 tablespoons per cup of swap to compensate for the extra 35% water-and-protein content, and expect a tangier crumb closer to a pound-cake density.

Tartar Sauce
10.01 tbsp : 1 tbsp
Base ingredient, add relish and lemon
10.0
adjustment for baking
Use 1:1 by tablespoon only in savory quick-breads where its relish bits and lemon won't fight the sweet. The base is mayo, so fat coverage is identical at 70%, but the chopped pickled cucumber adds 2-3% extra moisture per tablespoon — drop the recipe's water by an equal amount.

Sour Cream
7.51:1
Tangy and thick; works 1:1 in dips and baked potatoes, less rich than mayo
7.5
adjustment for this dish
1:1 by unit, but sour cream's 20% fat against mayo's 70% means cakes lose half their oil-and-emulsifier coating; add 3 tablespoons of neutral oil per cup. The pH 4.5 acid activates baking soda harder, so cut soda by a quarter teaspoon per cup to avoid a bitter aftertaste.
05
Hummus
6.71 tbsp : 1 tbsp
Creamy spread, very different flavor
6.7
adjustment for this dish
1:1 by tablespoon works only in savory crackers or flatbreads — hummus is 60% chickpea purée at 9% fat, plus tahini, garlic, and lemon, so sweet bakes will read off-balance. The chickpea protein adds structure that tightens crumb. Drop flour by 1 tablespoon per quarter-cup of hummus to keep doughs hydrated.
06
Plain Yogurt
5.01 cup : 1 cup
Thin with milk if needed; tangy and mild, lower fat swap in dressings and dips
5.0
adjustment for this dish
1:1 by cup, thinned with a tablespoon of milk if very stiff. Yogurt's 3-5% fat versus mayo's 70% means you must add a quarter-cup of neutral oil per cup of swap to keep cakes tender. The pH 4.4 acid reacts with baking soda — reduce soda by 25% to prevent metallic notes.
07
Greek Yogurt
5.01:1
Qualitative substitution — adjust to taste
5.0
adjustment for this dish
1:1 by unit. Greek yogurt is strained to 10% fat and double the protein of regular yogurt, so cakes set firmer and rise about 10% less. Add 3 tablespoons oil per cup of swap to recover oil-coating, and reduce baking soda by a quarter teaspoon per cup since pH 4.3 acid reacts hard.
08
Avocado
5.01 cup : 1 cup
Mash ripe avocado; creamy healthy swap in sandwiches and tuna salad, less tangy
5.0
adjustment for this dish
Mash one ripe avocado per cup needed. Avocado is 15% fat — mostly monounsaturated — versus mayo's 70%, so add a third-cup of oil per swap to keep crumb tender. The chlorophyll tints brownie-style bakes greenish unless cocoa or molasses dominates. Lemon juice (a teaspoon) blocks browning during the bake.
