What to Brush on Eggless Vánočka (Christmas Bread) for Shine and Color

Egg does three things at once on the surface: its protein browns together with sugar, the fat from the yolk gives shine and a richer golden color, and the dried layer acts like glue for almonds. Once you know which of these three things you actually need, picking a substitute takes ten seconds.

Color comes from the Maillard reaction, and that needs protein and sugar at the same time. So the breakdown is simple:

• Egg white gives mostly shine and almost no color.

• Egg yolk gives rich color and, thanks to the fat, a deeper, almost lacquered shine.

• Whole egg is the compromise that does both — which is why it's the most commonly used.

So a substitute needs to deliver at least two of those three qualities. That immediately explains why plain water doesn't work (nothing to brown) and why plain oil doesn't work either (no protein). We covered this in more depth in the article on why you brush yeasted dough with egg.

Without eggs, these all work: soy milk with maple syrup, plain unsweetened plant milk, cream or whole milk, a starch glaze, aquafaba with syrup, and sugar syrup brushed on after baking.

• Soy milk + maple syrup (2 tbsp : 1 tsp) — the best balance of color and shine. Soy, along with pea milk, is one of the plant milks highest in protein, and the syrup supplies the sugar. According to tests from the baking site King Arthur Baking, this combo beat every other plant-based option: syrup alone over-darkened the crust, while soy milk alone came out too pale.

• Unsweetened soy or pea milk on its own (2 tbsp) — a lovely golden color and shine comparable to egg wash; the syrup is mainly there for a richer color. The simplest option when you don't want to mix anything.

• Whipping cream or whole milk — the fallback for when you're just out of eggs but still eat dairy. The fat in cream gives a darker, almost lacquered surface; milk gives something softer and lighter.

• Starch glaze (1 tsp starch per 100 ml water, briefly boiled) — the shiniest option of all, but almost no color. Works best paired with something else: milk before baking for color, starch glaze right after baking for shine.

• Aquafaba (chickpea brine) — gives mild shine on its own but almost no color; without a teaspoon of syrup it's not really worth using.

• Sugar syrup or honey diluted with water 1:1, applied only after baking — gives shine and a sticky surface that holds almonds in place. This thick, it has no business going on raw dough — it would scorch; before baking, dilute it at least 1:2.

Treat almond milk as a last resort. It has only around 0.4 g of protein per 100 ml — among common plant milks, only rice milk has less — making it the weakest choice for browning; King Arthur didn't even include it in their test, admitting only that it "will do in a pinch." With a teaspoon of syrup mixed in, you'll get at least a pale golden surface.

If your vánočka keeps coming out pale, stir a pinch of instant coffee or cocoa into the milk. You won't taste it, but the crust will be a couple of shades darker.

For one loaf, 2 tablespoons of milk and 1 teaspoon of syrup is plenty — making more is wasted effort.

1. Stir 2 tablespoons of unsweetened soy milk with 1 teaspoon of maple syrup or honey until smooth.

2. Brush the risen loaf with a soft pastry brush right before it goes into the oven. A thin layer, no puddles.

3. About 20 minutes before baking finishes, open the oven and quickly brush a second coat. That second layer makes the biggest difference to the color.

4. Right after taking it out, you can brush it once more lightly and let it dry on a wire rack.

Unsweetened milk is a deliberate choice: sweetened and "barista" versions have a lot of added sugar and will scorch before the loaf is done baking inside.

A starch glaze is the cheapest way to get real shine on vánočka with absolutely no egg — all you need is starch and water.

1. Stir 1 teaspoon of cornstarch or potato starch into 100 ml of cold water.

2. Bring to a boil while stirring constantly and simmer for about a minute, until the mixture turns clear and thickens slightly to the consistency of a thin syrup.

3. Let it cool to lukewarm, then brush it onto the hot loaf right after it comes out of the oven.

Don't put it on raw dough — in the oven it would dry into a dull white film. The same goes for sticking almonds on: starch glaze always goes on the finished loaf, never before. Leftovers keep in the fridge for two to three days; just warm and stir before using again.

Five things people commonly suggest that don't hold up on vánočka: plain water, plain oil or butter, pure honey before baking, rice milk, and unsweetened aquafaba.

• Plain water has no protein or sugar, so there's nothing to brown. The surface stays dull and even a bit tougher, since the water dries out the crust from outside.

• Plain oil or melted butter will make the loaf greasy rather than shiny, and the fat actually slows down crust formation. Save the butter for after baking — that's where it adds softness and aroma.

• Pure honey or syrup before baking caramelizes long before the dough is done baking inside. You'll end up with a loaf that's dark, even bitter, on the outside and underbaked in the middle.

• Rice milk is low in protein (~0.1–0.3 g/100 ml) and leaves the loaf pale. Oat milk browns reasonably well, just with a bit less shine than soy.

• Unsweetened aquafaba gives a bit of shine but stays pale — you'll need to add syrup for color.

Brush twice: right before it goes into the oven, and again about 20 minutes before it's done. One eggless coat is almost never enough.

• Before baking brush only after the dough has risen, with a soft brush and no pressure. Risen dough is delicate — press too hard with a stiff brush and it'll deflate.

• Don't let the glaze pool into the gaps between the strands. A puddle in the braid stays damp, won't brown, and crumbles when you slice it. Wipe off any excess sideways with the brush.

• The second coat, in the last 20 minutes, quickly, keeping the oven open for as short a time as possible so the temperature doesn't drop.

• After baking only applies to syrup and starch glazes, and only on the hot loaf — on a cooled one, it stays as a sticky layer that never dries.

But brushing won't fix problems that started earlier. If your vánočka spread out sideways or you're wondering why vánočka cracks, the cause lies in the rising or braiding, not the glaze.

Almonds stick best without eggs to syrup diluted 1:2 with milk or water — brush it on, sprinkle the almonds, and press gently into the dough; raisins don't belong on the surface at all — work them into the dough instead. Plain plant milk is too thin for sticking, and the almonds will slide off during baking.

Egg works as glue because its protein sets in the oven and practically welds the almond in place. A substitute needs to be thicker to do the same job:

1. Brush the risen loaf with syrup or honey diluted 1:2 with milk or water. It's thicker than plain milk on its own, yet dilute enough that it won't burn in the oven.

2. Sprinkle sliced almonds from above, not from the side.

3. Gently press them in with your fingers so they touch the dough, not just the glaze layer. Press lightly — the dough has risen and is fragile.

Save the starch glaze for sticking almonds until after baking — it won't hold on raw dough and will just dry into a dull film. It's great on the hot loaf though, where it adds shine to almonds that are already baked.

Almonds brown faster than the loaf itself. Once they're getting darker than the crust, loosely tent the loaf with foil for the last 15 minutes. As for raisins: on the surface they turn bitter and burn before anything else does. If any poke out while braiding, push them back under the surface before the loaf goes into the oven.

A pale loaf needs more protein and sugar in the brushing mix; a too-dark one needs foil and a lower temperature — not a different glaze. Both are fixable without changing the whole method.

A pale loaf is fixed with a stronger brushing and checking the temperature:

• Swap rice or almond milk for soy or pea milk. They have noticeably more protein, which means more browning.

• Add 1 teaspoon of syrup or honey per 2 tablespoons of milk.

• Brush twice. The second coat, 20 minutes before the end, makes the biggest difference.

• Check your oven temperature. Vánočka usually starts baking at 170–180°C (340–355°F) and finishes at 150–160°C (300–320°F). If it stays pale, the oven is likely running cooler than it shows — check with an oven thermometer.

A too-dark loaf is fixed with foil and gentler baking:

• Loosely tent it with foil for the last 15–20 minutes. The inside will finish baking while the crust stops darkening.

• Lower the temperature by 10°C (about 20°F) and bake five to ten minutes longer.

• Dilute the glaze: more milk, less syrup. The more sugar on the surface, the faster it darkens.

• Move the tray to a lower rack if mostly the top is darkening.

Yes, the same substitutes work on any sweet yeast dough — mazanec included, as well as smaller sweet yeast rolls. Only the baking time changes, not the principle: protein and sugar create color, fat and starch create shine. Smaller pieces brown faster, so apply the second coat earlier — around 10 minutes before the end.

If you're also missing eggs in the dough itself, that's a different challenge than brushing — there, eggs hold structure and softness, not color. You'll find the ratios that work in our egg substitute chart for baking.
