This unexpected ingredient ruined my holiday cookies!

We all put so much time, energy, money, and LOVE into our holiday baking that it’s a shame to let one unassuming little ingredient take it all down. Read on to find out how to protect your holiday goodies!

My very first batch of holiday cookies was a complete fail

I love to bake cookies, and there’s no better time than the holidays ~ I finally have a reason to bake all day long, it’s heaven! I stock up on all the pantry essentials, and gather together my cookie cutters, rolling pins, and baking sheets. My ingredients are at room temperature, the butter and eggs are fresh, it’s a new bag of flour, and yes, I’ve even bought a new can of baking powder. I’m prepped and ready, what could go wrong?

what’s the unexpected ingredient that can ruin holiday cookies?

The other day I made my first batch of holiday cookies. I had just finished when my daughter, who has impeccable timing when it comes to fresh baked cookies, wandered into the kitchen. I did what I always do and picked out a couple for us to taste test. So far, so good.

After one bite it became apparent that something was wrong. It took us a while to sleuth it out…we tasted everything separately…the soft sugar cookies were perfect. The cream cheese frosting was delicious as always…

It was the sprinkles!

They’d gone bad. In fact, they tasted rancid, and the off flavor and smell was enough to spoil the whole batch of cookies. I was horrified, especially since I’d just bought them fresh this season. After I got over the shock, I did a little research.

do sprinkles go bad?

Yes, some do, despite what you often read about them keeping forever. In fact that’s what I’ve always thought. I used to keep my holiday sprinkles year after year, don’t we all? Now I know better. From now on I’ll be tasting(or sniffing) before sprinkling, for sure. And I’ll be sure to toss any with a bad odor or off flavor.

oil is the culprit!

The main ingredients in most sprinkles include:

  • corn syrup
  • sugar
  • cornstarch or emulsifiers
  • wax or shellac
  • artificial food colorings
  • oil

Most of these ingredients do last a long time, and are resistant to spoiling, but oil is the culprit here as it can spoil and become rancid. And while many sprinkles can last years in a dry, dark spot like your pantry, some do go ‘off’. Rancid oil has a very distinctive odor, you might know it from whole grains, nuts and seeds, or cooking oils that have spoiled.

what do sprinkles taste like, anyway?

Sprinkles are not known for their wonderful flavor, in fact, they normally don’t have any taste at all ~ they’re purely decorative and add a textural element to baked goods.

At best sprinkles provide a festive color and a light crisp crunch to cookies (l love the tiny nonpareils on my sprinkled sugar cookies.)

I try to avoid large shaped sprinkles because, however cute, they really aren’t pleasant to eat. When I do use them, I use them sparingly (check out the cute collars on my gingerbread bears.)

If you’re baking for kids, sprinkles are almost always a good idea, but if you’re baking for a mixed audience, think twice before you sprinkle! Make sure they taste and smell fresh, and make sure they don’t overwhelm your delicious dessert.

how to tell if sprinkles have gone bad

Most often you can’t tell by looking at sprinkles if they’ve gone bad. You’ll really only know by smelling and tasting them. If they have an off flavor or smell, toss them.

can you use sprinkles past their expiration date?

Yes, if your sprinkles pass the taste and sniff test, you’re good to go, even if they’re a bit past their expiration date.

you can always make your own homemade sprinkles!

To be completely sure that your sprinkles are fresh, you can make them yourself. You’ll need a piping bag and small round tips for piping out the fine thread-like mixture that will dry so you can cut them into tiny sprinkles. You can make them in any color you can imagine! I’ll take you through the process here: How to Make Homemade Sprinkles!

    Crazy! I was just getting ingredients out for our homemade chocolate dipped pretzels. I always sprinkle with nonpariels, colored sugars (red & green) and sprinkles. I actually called Michael’s this morning to see if they have the Christmas themed sprinkles, they do. I’ll definitely do a sniff and taste test before sprinkling. BTW, the homemade chocolate dipped pretzels taste great, in my opinion. ?

      There are quite a lot of online sources that have a huge variety, one commenter mentioned And, like I said in the post, discount department stores have great selections, but you just have to check them before using. I do like Williams Sonoma, and Wilton brand, which you can find all over, is a good one.

    Been there, done that but with other recipes and ingredients. Recently Mom made her no-fail pie crust in the food processor and it didn’t roll out smoothly. I asked what she did different because I just knew ……well, she used lard instead of Crisco. I made another batch after fetching some Crisco and it turned out as usual. Sometimes it’s not worth the time or money to switch ingredients, which is not the case with you. Can you keep them in the freezer or fridge? I don’t use Olive Oil as often as some so I store it in the fridge and put the bottle under hot water or set it out early because it solidifies but I’ve never had rancid OO since. I keep my Sesame Seeds in the freezer after reading how they turn rancid. Some packaging tells you to refrigerate or freeze if you won’t be using it all soon but so many don’t.

      Great question, I should add this to the post ~ knowing what I know now, I would buy them either from your regular large grocery store, where the stock turns over often, or from a specialty store like Williams Sonoma, etc. I think I would avoid discount stores like Home Goods, Marshalls, etc. That’s not to say that those stores don’t have wonderful stuff, but I do get the impression that food items aren’t as fresh or reliable.

        My spoiled sprinkles were technically fresh according to the expiration date, and were bought last month from Home Goods.

      Mine are ancient, I am sure. Thank you for mentioning this. Sorry you had to toss stuff. I toss occasionally because my gluten free attempts don’t always work. It’s never fun.
