Can I substitute something for an egg?!

[FurchesterCatastrophy]

It's my daughter's birthday tomorrow and I'm baking a cake tonight. I've just realised I only have 2 eggs and I need 3. I'm using a packet mix (don't judge). I don't want to go to the shops as I don't feel this qualifies as an essential shop. Can I substitute something for it? Butter? Baking powder? Help!

use 60g of plain yogurt as a substitute for one egg if you have it

You'll need something wet, eggs bind the mixture together. A splash of milk or a spoonful of oil will do the same.

I made eggless pancakes this morning, as forgot to check the shops had any before promising the children. I would guess if you can only use what you have in the house adding a bit more flour, a bit more baking powder and a bit more milk probably wouldn't do any harm (as a guess from what was in eggless pancake recipe). If you haven't got any of those I'd just make 2/3 of the mix, with the 2 eggs and divide any other ingredients by 2/3. Cook for slightly less time to account for being smaller.

I’ve used flaxseed before and it was perfect. Here’s a chart with loads os egg substitutes.

Sorry...meant to say lots of substitutes

My baker friend used a dollop of mayo when she struggled to get eggs.

I'd just add a tbsp of some light tasting vegetable oil. I know some replace eggs for apple purée/sauce - I might have read that in a vegan cookbook?
No judgement on the packet mix whatsoever ( I use them all the time and make no apologies - not all of us are gifted with the baking gene)

Mashed banana, apple puree or some of the liquid from a can of chickpeas would be my suggestions.
Or, just use 2/3 of everything!

Thank you everyone. I have plain yoghurt, oil, bananas so I'll see what I fancy tonight!

There was an article in The Guardian or The Observer the other day going through all sorts of recipes for cakes without eggs, fat, flour, sugar etc. Useful.

Will you let us know how it turned out? Hope she has a great birthday! 🎂

Just add a little more moisture eg milk or fruit puree.

Thank you for all the advice. I used 60g of plain yogurt and it worked really well

Oil, look up vegan cakes. It doesn't have to be vegan but it will show you the quantities you need.
