The Complete Guide to Vegan Baking: Every Egg and Dairy Substitute Tested

Before you can substitute eggs effectively, you need to understand why they're in the recipe. Eggs perform multiple distinct functions:

**Structure (protein coagulation):** Egg proteins denature and set during baking, providing structure. Custards, cheesecakes and egg-heavy cakes rely on this. The best substitute here is silken tofu (blended smooth) or a commercial egg replacer like JUST Egg.

**Leavening (emulsification + air incorporation):** When beaten, eggs trap air bubbles that expand during baking. Aquafaba (the liquid from canned chickpeas) is the gold standard here — it whips to stiff peaks like egg white and performs identically in meringues, macarons, mousses and sponge cakes. 3 tablespoons of aquafaba = 1 whole egg; 2 tablespoons = 1 egg white.

**Binding (protein network):** Eggs hold ingredients together. For binding in cookies, pancakes and burgers: flax egg (1 tbsp ground flaxseed + 3 tbsp water, rest 5 min) or chia egg (same ratio with chia seeds). Both form a gel that binds effectively.

**Moisture:** Eggs contribute significant moisture. Adding a tablespoon of extra plant milk to vegan batters compensates for this.

**Fat and richness (yolk):** Egg yolks contribute fat and emulsifying phospholipids. Sunflower oil plus a pinch of black salt (kala namak — a sulphurous salt that mimics egg flavour) can replicate this element.

**Plant milks in baking:** The good news: most plant milks perform very similarly to cow's milk in baking. The key properties are fat content and protein content, which affect browning and texture. • **Oat milk** — the most neutral flavour, good fat and protein profile, excellent in cakes, muffins and pancakes. Barista versions (higher protein, added oil) are ideal. • **Soy milk** — highest protein content of plant milks; best for recipes where browning and structure matter. Good for bread, yorkshire puddings and creamy sauces. • **Full-fat coconut milk** — significantly higher fat, ideal for whipped cream, ganaches, ice cream and tropical-flavoured bakes. Can overwhelm delicate flavours. • **Almond milk** — lower fat and protein; acceptable in lighter applications but may produce slightly drier results in cakes. • **For buttermilk:** Add 1 tablespoon of apple cider vinegar or lemon juice to 240ml plant milk. Leave 5 minutes to curdle. This acidulation activates bicarbonate of soda in the recipe and produces the tenderising acidity of conventional buttermilk.

**Plant-based butter:** • Block-style vegan butters (e.g., Miyoko's, Flora Plant, Country Crock Plant Butter) perform very closely to conventional butter in baking due to their fat content and structure. Tub/spreadable versions contain more water — not appropriate for pastry. • For creaming (incorporating air into butter and sugar), vegan block butter works identically. • For laminated pastries (croissant, puff), high-fat European-style vegan butters are available and work well.

**Cream alternatives:** • Whipped coconut cream: refrigerate full-fat coconut milk overnight; scoop the solidified cream layer and whip with an electric mixer. Achieves real peaks; use in lieu of whipped cream. • Oat cream or soy cream: good for custards, ganaches and sauce. Less whippable but excellent cooked.

**Problem: Dense, heavy cake** Cause: Insufficient leavening or wrong egg substitute for the application. Solution: In cakes where eggs provide lift, use aquafaba AND increase bicarbonate soda by 25%. A small addition of apple cider vinegar (1 tsp per 240ml plant milk) enhances leavening.

**Problem: Gummy texture** Cause: Too much flax or chia egg, or overmixing after adding wet ingredients. Solution: Use no more than 1 flax/chia egg per recipe unless the recipe specifically requires more. Mix batter only until just combined.

**Problem: Doesn't hold together / falls apart** Cause: Insufficient binding. Eggs provide a protein network that holds baked goods together. Solution: Add 1–2 tablespoons of tapioca starch to the batter (it gels on heating and provides strong binding). Or use chia egg rather than flax — chia produces a slightly stronger gel.

**Problem: Pale top / poor browning** Cause: Lack of Maillard reaction from egg proteins and milk sugars. Solution: Brush tops with a mixture of maple syrup + plant milk before baking. Or add 1 tablespoon of agave syrup to the batter for improved browning.

**Perfect Vegan Chocolate Cake:** Dry: 200g plain flour, 200g sugar, 60g cocoa, 1 tsp bicarb, ½ tsp salt Wet: 240ml oat milk + 1 tbsp ACV (leave 5 min to curdle), 120ml neutral oil, 2 tsp vanilla, 120ml hot coffee (amplifies chocolate flavour) Method: Combine dry. Combine wet. Fold together until just combined. Bake 180°C / 30–35 min. The coffee + ACV combination produces exceptional rise and fudgy texture.

**Aquafaba Meringues:** 120ml aquafaba (from 1 tin of chickpeas — use the unsalted variety), ½ tsp cream of tartar (stabilises the foam), 150g caster sugar, 1 tsp vanilla Method: Whip aquafaba + cream of tartar to soft peaks (~5 min). Gradually add sugar, beating to stiff glossy peaks (~10 min total). Pipe or spoon onto lined trays. Bake at 100°C for 1.5–2 hours. Cool in the oven. Results: crisp, light, and indistinguishable from egg meringues in a blind tasting.

**Vegan Shortcrust Pastry:** 200g plain flour, 100g cold vegan block butter (cubed), 2–3 tbsp ice water, pinch of salt Method: Rub butter into flour to breadcrumb stage. Add ice water 1 tbsp at a time until dough just comes together. Rest 30 minutes in the fridge. Behaves identically to conventional shortcrust.
