Preheat oven to 400 degrees Fahrenheit (200 degrees Celsius).

Combine dry ingredients in a large bowl and set aside. Place peanut butter, brown sugar, and honey in a large microwaveable bowl and mix; microwave on High until bubbling, one to two minutes. Add vanilla and stir until blended.

Pour the peanut butter mixture over the dry ingredients and stir until coated. Arrange on a Gefen Parchment Paper-lined cookie sheet and bake for 20–30 minutes, stirring occasionally. Remove from oven and allow to cool before placing in bags.
