Step 1: Preheat the Oven

Preheat your oven to 350°F (175°C) and line a baking sheet with parchment paper.

Step 2: Prepare the Butter Mixture

Melt the butter in a microwave-safe bowl on medium/low power. Let it cool slightly after melting.

Step 3: Whisk Egg White and Vanilla

Separate the egg white from the yolk. In a small bowl, whisk the egg white and vanilla into the cooled butter mixture. Set aside.

Step 4: Mix Cinnamon Sugar

In another bowl, mix the granulated sugar and ground cinnamon together until evenly combined.

Step 5: Coat the Pretzel Sticks

Place the pretzel sticks in a one-gallon zip-top bag. Pour the butter mixture over them. Gently shake and mix to coat all the pretzels evenly.

Step 6: Add Cinnamon Sugar

Add the cinnamon sugar mixture to the bag with the coated pretzels. Shake gently to ensure all pretzels are evenly coated.

Step 7: Bake

Spread the coated pretzels in an even layer on the prepared baking sheet. Bake for 15 minutes, stirring once halfway through baking.

Step 8: Cool Before Serving

Remove the pretzels from the oven and stir immediately to prevent sticking. Allow them to cool completely before serving.
