I'm making a packet mix of pancake batter that doesn't lend itself to partial mixes - it's hard to split "1 egg" as an ingredient. How long would pancake batter last in the fridge? Even if it's a worst case of a day or two, I'd still like to know.
1I ended up using it the next day and the pancakes were fine. Judging by the comments I wouldn't want to leave it much more than that.– dlanodMar 19, 2011 at 22:20
Bisquick-originated pancake and waffle batter lasts a day, two at the most.
Data: in college, I made pancakes or waffles every day for a year and a half, making the batter on day 1 and then cooking it on days 1, 2, and 3. Once in that time I got sick on Day 3. Based on that experience, more than 24 hours is getting sketchy, though 48 seems to work most of the time.
I doubt that the batter would actually start to spoil after 3 days, unless the ingredients (in particular, milk) were already on their way out when you prepared the batter. More likely, you got sick from some other cause. But, as many of the other answers point out, you lose a lot of the important properties of the batter after just a day that can affect food quality.– alexwDec 23, 2016 at 0:44
Unless you're making flat "crepe" style pancakes, your batter will not really work properly later. Once the baking powder is mixed with wet ingredients, you need to cook it as soon as possible or its rising power will start to be lost. This will be true of any batter that has baking powder as its rising agent.
You're probably better off to make all your pancakes and then refrigerate the leftover pancakes. You can toast them to reheat them later.
1You're right but it's worth reasserting that if the mix is for 'crepe' style pancakes then the mix will be fine (possibly better) in the fridge for at least a day– nixyMar 19, 2011 at 11:21
I have no idea what type of pancake you're making, but I had answered your question for chemically leavened pancakes in case someone stumbled upon that question (even though the earlier question was specifically for crêpe like pancakes.)
If you're using baking soda as a leavening, it'll have already given its all by the time you cook it hours later ... but you'd have to add baking powder to compensate when it's time, as there might not be enough acid left for baking soda. Baking powder in the batter isn't as much of a problem if it's double-acting, where it'll give some leavening when it gets wet, and again as it gets warm. Of course, you don't want to add too much baking powder, as it can give a metallic taste.
It's also worth mentioning that it is possible to halve an egg; in this case, if you're going to be using the other half of the mix in a day or two, it might be easier to measure by mixing all of the wet ingredients together and then use half.
Thanks for the egg halving link. I never thought of doing that, it's quite clever.– dlanodMar 19, 2011 at 22:20
I found this site looking for the reason my premade pancake batter is turning out super flat pancakes. I have found without fail that the batter we make fresh everyday makes a fluffy pancake, without fail the next morning that same batter hits the grill and looks like a crepes .
2This has been flagged as not an answer, but I think it sort of is: it indicates pretty clearly that the batter doesn't last until the next morning.– Cascabel ♦Aug 10, 2015 at 2:17
Don't count on the batter lasting very long. Just make all the pancakes and freeze them. If you refrigerate them, they'll get pretty stale, pretty quickly.
