How to Heat Treat Flour

Whether you want to make edible cookie dough or energy balls, it’s important to heat treat your flour before use. This is because raw flour can contain harmful bacteria like salmonella and E coli.

This simple process cooks the flour so it kills any bacteria and makes it safe to eat. Learn how to heat treat flour using the microwave, oven or stove top.


The FDA says that flour can have harmful bacteria like salmonella and e. coli in it. These bacteria are killed by heat, so the best way to make sure that the flour you’re using in no-bake recipes is safe to eat is to heat treat it. The good news is that it’s a super simple process.

You can use a microwave, oven or pan to heat treat flour for no bake recipes. The easiest and most convenient way to do it is in the microwave. You can even make a big batch in advance, and store it in an airtight container until you’re ready to use it.

If you’re in a hurry, this is the fastest way to heat treat flour. Place 1 cup of flour into a heat-safe bowl, and microwave it in thirty-second intervals until the temperature reaches 165 degrees Fahrenheit. Be sure to stir the flour in between each interval. If you forget to stir it, the flour might be cooked in some places and not others, and that can result in clumps of burnt flour that won’t work for your no-bake recipe.

To avoid the risk of burning the flour, you can also heat treat it in the oven. This method can take longer, though, and it’s harder to get the flour to a precise temperature. Preheat the oven to 165 degrees Fahrenheit, and spread the flour evenly over a baking sheet. Cook it in two-minute increments, until the temperature reaches 165 degrees.

A third option is to warm the flour in a pan on the stove. This method is easy enough, but it can be a little messy. You’ll need to mix the flour thoroughly with your hands, so that there aren’t any clumps of uncooked flour. If you do this, be sure to wear rubber gloves and be careful not to burn yourself. You can also purchase pre-heated flour at some grocery stores, if you’d prefer not to handle raw dough. The brand that you choose may affect the taste of your finished no-bake cookies. So, be sure to try a couple of different kinds before making a final decision.


The oven is a kitchen staple, so it’s no surprise that you can use it to heat treat flour. This is one of the most popular ways to do it, and it’s simple enough for a beginner baker to master. Just make sure that you’re using a microwave-safe bowl and that the oven is set to a temperature that will kill bacteria.

Most cooks don’t realize that raw flour is a potential health risk. The wheat kernels that flour is made from grow in fields and are exposed to a variety of bacteria, including salmonella and E coli. These microbes are filtered out when the grains are turned into flour, but they don’t get killed completely. That’s why it’s important to always heat-treat flour before using it in any recipe, especially no-bake treats.

While some cooks may be tempted to skip the step and simply use flour straight out of the bag, this can lead to serious illness. In fact, 66 percent of people who eat raw cookie dough or cake batter report getting sick after eating the food. This is why it’s vital to take the time to heat-treat flour, which is an easy and effective way to kill any potentially harmful bacteria.

Flour should be heated to at least 160 degrees Fahrenheit in order to kill any bacteria. You can do this in a number of different ways, but the easiest and most convenient is by using a microwave or an oven. The heat should be applied evenly to the entire batch of flour and stirred regularly until it reaches the right temperature.

Ultimately, it’s up to every individual whether or not they want to heat-treat their flour. But if you’re a fan of no-bake treats, such as these edible chocolate chip cookies or this funfetti dip, it’s worth the extra step to keep yourself healthy and safe!

Warming in a Pan

If you want to use flour in recipes like cookie dough or other no-bake treats that call for raw flour, it is important to heat treat the flour. This process is quick and easy, so there is no excuse for not doing it. It is also the best way to ensure that the flour is safe to eat and that any bacteria has been killed.

It’s hard to believe, but it is true that raw flour can carry harmful bacteria, such as salmonella and E coli. This is because it has not been cooked in any way after being milled, bagged and sent to grocery stores. It is for this reason that most people will see a warning on the back of the flour bag advising consumers not to eat the flour raw.

While many people understand the dangers of eating raw eggs, not all are aware that the same can be said for flour. According to a research project conducted by Feng and his colleagues at the Center for Low-Moisture Food Safety, housed at Michigan State University, only 85 percent of consumers knew that flour could be harmful to consume raw.

The simplest way to heat treat flour is in the microwave. This method works with both bleached and unbleached flour. All that is required is a microwave-safe bowl and an instant-read thermometer. Put the flour into the bowl and stir to help it heat evenly. Heat in short increments of 2 minutes, stirring and moving the flour around each time until it reaches 160 degrees. This should take no more than 10 minutes or so, depending on your microwave.

Once the flour has reached its target temperature, remove it from the oven and cool completely. It is now ready to use in any recipe that calls for raw flour. It will last for up to 12 months if stored in an airtight container. This is just one of many ways that you can heat treat flour to make it safe for no-bake treats and edible cookie dough. It is an easy step that will keep you healthy and able to enjoy all the no-bake goodies you love!


Flour is a pantry staple that most home cooks are familiar with. It is a very basic ingredient that can be used in so many recipes and it is important to know how long it lasts before it goes bad. The shelf life of flour depends on how it is stored. Flour needs to be kept in a dark place away from moisture, heat and pests in order to keep it as fresh as possible.

You may have noticed that flour is often sold with a best before date. This is a date that the manufacturer gives as an estimate of how long the product will be safe to use once it has been opened. However, this does not mean that the flour will be bad after this date. If the flour is able to be stored properly it will last longer than this.

If you store your flour in a dark and dry place it can last up to 10 years. When storing flour you should make sure that it is completely sealed in a plastic bag or a Mylar bag. Placing a moisture absorber in the bag can also help it to last even longer.

Moisture is one of the main causes of flour going bad. When moisture enters a container of flour it can encourage the growth of mold and bacteria which can be harmful to consume. Moisture can also cause clumping and can encourage the flour to absorb nearby odors.

The temperature of where you are storing the flour is also something to consider. It should be stored in a cool temperature because warm temperatures can cause the flour to go rancid faster.

When you are storing your flour it is also important to keep it out of the light because it can affect the flavor and texture of the flour. It is best to store it in a dark cupboard or even a cooler if you have one. It is also a good idea to purchase a set of airtight containers that you can store your flour in. This will help to prevent moisture from entering the flour and it will also keep out pests like weevils or insect eggs.
