Preheat the oven to 320˚F. Line a baking sheet with parchment paper or a silicone baking mat.
Place the Nutella and honey in a small bowl, and microwave for 20-30 seconds. Mix together until smooth.
In a medium bowl, mix together the oats and pretzels. Mix in the melted Nutella mixture until the oats are coated with the mixture.
Spread the oat mixture on the prepared baking sheet, and bake for around 17 minutes. Allow the granola to cool completely before breaking into clusters.
Notes
Store in an airtight container at room temperature for up to 3 weeks.
Use quick oats instead of rolled oats for a less chewy granola.
Line the baking sheet with parchment paper or a silicone baking mat to avoid having the granola stick to the baking sheet.
Allow the granola to cool completely in order to create the crunchy granola clusters.
