Heat Treating Flour: The Path To Safe Edible Dough

Learning How To Heat Treat Flour allows me to enjoy one of my guilty pleasures safely… eating cookie dough! Now I don’t have to think twice when I’m licking the spatula!

Don’t worry, my edible cookie dough recipes such as Edible Peanut Butter Cookie Dough and Easy Edible Monster Cookie Dough also don’t include raw eggs. So, it really is safe to eat from all aspects!

The only thing it isn’t safe for is my waistline! Especially when I dig into my Edible Brownie Batter that’s made with only 3 ingredients!

The Importance Of Heat Treating Flour

Consuming raw flour puts us at risk of getting sick from the germs and bacteria that can sometimes be found in flour. By heat treating the flour, we can then eat our favorite doughs and recipes safely!

To properly heat treat flour, it must reach a temperature of at least 160 degrees F. The high temperature then kills off any germs or bacteria that may be in the flour.

Ingredients & Kitchen Tools Needed To Heat Treat Flour

  • All-Purpose Flour – As much as your recipe requires
  • Oven or Microwave
  • Baking Sheet or Microwave-safe Bowl
  • Whisk
  • Kitchen Thermometer

How To Heat Treat Flour At Home

Heat treating the flour can be done in two different ways. But both ways are quick and easy, so before you know it it’s ready to be used in your edible dough recipe of choice!

  1. Oven Method: The first method is to spread the flour out in a thin layer on a rimmed baking sheet and bake it. This method takes just 5 to 6 minutes at 350 degrees F.

Another common method to heat treat flour is to just microwave it! Don’t worry, how to heat treat flour in the microwave is as easy as in the oven!

2. Microwave Method: To do so, just add the flour to a microwave-safe bowl and stir it between intervals. With both methods, once the flour reaches a temperature of at least 160 Degrees F with a food thermometer, it’s safe to use.

How To Use Heat Treated Flour

Now that you know how to heat-treat flour in the oven, you’re ready to make edible cookie dough! I’d suggest you use heat treated flour in my Irish Cream Edible Cookie Dough, Edible Gingerbread Cookie Dough, or Cookie Dough Truffles! They’re everything you love about raw cookie dough but safe to eat without the risk of harmful bacteria!

If you love sugar cookies, I highly recommend using this kitchen hack to make a batch of Edible Sugar Cookie Dough.

Rebecca’s Tips

  • Use a kitchen thermometer (affiliate link) to check the temperature of the flour! Once it reads 160 Degrees F it’s safe to use.
  • The flour is over baked if the temperature of it becomes too high. Unfortunately, you will likely notice a taste difference in your recipe if your flour is over baked!
  • Once you know how to heat treat flour, you might find the method handy for other flour-based baking mixes. Some dessert dip recipes like my Edible Brownie Batter call to heat treat the mix first. And these methods are what I use when doing so!

Ingredients
  

Instructions

Oven Method

  • Spread the flour out on a cookie sheet and bake at 350°F for 5 to 6 minutes.
    1 cup all-purpose flour
  • Whisk after baking to break it up since the heat can cause clumping. Allow it to cool before using it in a recipe so it doesn't melt the other ingredients.

Microwave Method

  • Alternatively, you can microwave the flour in a microwave-safe bowl at 30-second intervals, whisking after each until the flour reaches a temperature of 160°F so it's safe to use.
  • Allow it to cool before using it in a recipe so it doesn't melt the other ingredients.

Notes

  • How Do I Know When The Flour Reaches The Right Temperature? Simply use a kitchen thermometer to check the temperature of the flour! Once it reads 160 Degrees F it’s safe to use.
  • Can I Save Heat Treated Flour? Yes, heat-treated flour can be saved in an airtight container at room temperature. However, since it takes just a few minutes to heat treat it, I prefer to make a fresh batch whenever I need it.
  • How Will I Know If I Over Baked The Flour? The flour is over baked if the temperature of it becomes too high. Unfortunately, you will likely notice a taste difference in your recipe if your flour is over baked!
  • Does This Method Work For Cake Or Brownie Mixes? Yes! Some dessert dip recipes like my Edible Brownie Batter call to heat treat the mix first. And these methods are what I use when doing so!
