28 Emergency Baking Ingredient Substitutes Everyone Should Know
Inside: The 28 MOST COMMON baking ingredients and ingredient substitutions to save the dessert day. Not a mile-long list of obscure ingredients, but the ones you really need to know + a free printable!

It never fails. You’re in the middle of making oatmeal cookies. Or the dessert for today’s potluck. Or your mother-in-law’s specialty cake—and she’s coming to dinner.
And suddenly your heart drops. You could have sworn you had butter. You ALWAYS have butter. But not today.

And baking is an exact science. Unlike other kinds of cooking, you have to follow the rules of ratios. And ingredients. And amounts.
It seems to be either those ingredients you always have on hand like butter, or the ones you never use like buttermilk, that are always missing at the worst time.

But before you throw in the kitchen towel or make a grocery store run, you may already have a good swap right under your nose!
The 28 Most Common Baking Ingredients and Substitution Options to Save the Dessert Day.
This isn’t the endless list of every unusual and unlikely baking substitution ever for you to wade through. These are the most common and most likely ingredients we cook with.
Most of the ones you really need to know.

Remember—because baking is a precise art, changing any of the specific ingredients may change the end result. The outcome may be slightly different in flavor or texture, but you will still have an edible dessert!
