Preheat your oven to 350°F.
Spray an 8x8 baking pan with nonstick cooking spray and then line the pan with parchment paper. This will allow you to easily remove the blondies from the pan.
In a small sauce pan, melt your butter over medium heat. Once the butter has melted, set the pan aside and allow the butter to cool slightly.
1 cup unsalted butter
In a medium mixing bowl, whisk together your dry ingredients of flour, baking powder and salt and set the bowl aside.
1 cup all purpose flour, ¼ teaspoon baking powder, ¼ teaspoon fine sea salt
In a large sized mixing bowl, whisk together your melted butter, brown sugar, egg, and vanilla bean paste until well combined.
¾ cup light brown sugar, 1 large egg, 2 teaspoons vanilla bean paste
Add in your dry ingredients into your wet ingredients and stir until combined.
Using a rubber spatula, fold in your roughly chopped mini pretzels and chocolate chips.
1 cup mini pretzel twists, 1 cup chocolate chips
Pour the batter into the prepared pan and spread it out evenly with your spatula.
Bake for approximately 35 to 45 minutes. Oven times do vary so check the blondies at 25 minutes to make sure they aren’t browning too fast on top. If they are, cover loosely with a foil tent and continue baking. You should be able to insert a toothpick or knife in the center and it should come out clean or with a few moist crumbs.
