Then, warm the butter, honey, brown sugar and sea salt over medium-low heat until the butter is melted and the sugar is dissolved.
Stir in peanut butter and vanilla extract until smooth.
Then, stir in quick cooking oats (and optional cinnamon).
Let the mixture cool slightly.
While the peanut butter granola bar mixture is cooling, chop the peanut butter chips into smaller pieces (or use mini peanut butter chips).
Then, stir the chopped peanut butter chips into the slightly cooled granola bar mixture.
Gently press the mixture evenly in the prepared baking dish.
If desired, drizzle peanut butter over the top of the granola bars.
Cover and transfer to the refrigerator to chill/harden.
Cut into 8 or 16 pieces and serve chilled or room temperature.

Ingredient Substitution Notes
Salted butter. unsalted butter works well.
Honey. maple syrup can be used in place of honey, however it will (obviously) impart a maple flavor and won't taste as authentic as using honey would.
Light brown sugar. coconut sugar is a good, unrefined, substitute.
Creamy peanut butter. I suggest using peanut butter that is solid at room temperature.
Quick cooking oats. For the best texture, do not substitute quick-cooking oats. To make them at home, put 2 ½ cups old-fashioned oats in a food processor or blender and pulse 2-4 times until the oats are cut into small pieces.
Store/FreezeStore these peanut butter granola bars in an airtight container in the refrigerator for 5 to 7 days, or in the freezer for up to 2 months. Thaw at room temperature - do not microwave.
