Notes
*This recipe is egg-free and is safe to eat raw as long as the flour has been properly heat-treated.**To heat-treat flour: Place the flour in a microwave-safe bowl and heat it on high in 30-second intervals, stirring between each interval, until the flour reaches 165°F. This usually takes about 1 to 2 minutes.OR: Spread the flour on a baking sheet and bake at 350°F (175°C) for 5-7 minutes. The internal temperature should reach at least 165°F to kill any potential bacteria. Let the flour cool completely before adding it to the cookie dough.
