1/4 teaspoon salt 1/4 teaspoon red pepper flakes (or to taste)
Preheat oven to 300 degrees F.
Place popcorn in a large bowl. Scatter peanuts over top; set aside.
Stir together peanut butter, butter, honey, brown sugar, and hot sauce in a small, microwave safe bowl. Heat in microwave about 30 seconds. Stir to blend.
Drizzle the peanut butter sauce over the popcorn. With a large spoon, stir popcorn until evenly coated. Spread mixture onto a rimmed baking sheet and bake 15 minutes or until lightly browned. Allow popcorn to cool and serve immediately
