When To Heat Treat Flour
Raw flour can contain harmful bacteria, like E. coli. So if you’re making no-bake treats, like edible cookie dough or brownie batter, make sure to heat-treat your flour first!
You can heat treat flour in the microwave or oven. Just make sure to have a thermometer on hand to ensure the flour reaches the right temperature!
How to Heat Treat Flour
There are two ways to heat treat flour: by baking it or microwaving it!
For the microwave method, add flour to a microwave-safe plate or bowl. Microwave at 15-second intervals, stirring in between, or until the flour reaches 160°F/70°C. This should take between 1-2 minutes. Let fully cool and make sure to sift the flour to get rid of any clumps before using!
For the oven method, add flour to a lined baking sheet. Bake at 350°F/177°C for 7-10 minutes, stirring halfway, until the flour reaches 160°F/70°C. Let fully cool, and make sure to sift the flour to get rid of any clumps before using!
