First Step: Preheat and Prep. Preheat your oven to 350°F (175°C). Grease or line an 8×8 or 9×9 inch baking pan with parchment paper and spray it with non-stick cooking spray. Gather all your ingredients, double-checking any dietary substitutions you plan to use.

Second Step: Combine Wet Ingredients. In a mixing bowl, cream together the softened or melted butter with both brown sugar and granulated sugar until the mixture is combined and a bit creamy. This step is crucial for creating the blondies’ moist, tender texture.

Third Step: Add Eggs and Flavoring. Beat in the eggs one at a time to the butter and sugar mixture, ensuring each is fully incorporated. Follow with the vanilla extract and mix until smooth and uniform. For vegan versions, substitute eggs with flaxseed egg alternatives.

Fourth Step: Mix Dry Ingredients. In a separate bowl, whisk together the all-purpose flour, baking powder, and salt. For gluten-free adaptations, replace the flour with a suitable gluten-free blend.

Fifth Step: Combine Wet and Dry. Gradually add the dry ingredients to the wet mixture, stirring gently until just combined. Avoid overmixing to ensure the blondies remain tender and chewy.

Sixth Step: Add Pretzels and Chocolate. Fold in the crushed pretzels and chocolate chips, distributing them evenly throughout the batter to ensure every bite has a delicious crunch and chocolate burst.

Seventh Step: Assemble and Add Caramel. Spread the thick batter evenly into the prepared baking pan. If using, drizzle the salted caramel sauce in a zig-zag pattern over the top. Lightly sprinkle the coarse sea salt for that signature sweet-salty finish.

Final Step: Bake and Cool. Bake for 20-25 minutes if you prefer a gooey center or up to 30 minutes for firmer blondies with a cookie-like texture. Test doneness by inserting a toothpick – moist crumbs are ideal especially when caramel is included. Remove from the oven and if desired, drizzle extra caramel sauce and sprinkle some coarse salt over the hot blondies. Let cool for at least 20 minutes to set properly before slicing. For best results, let caramel-drizzled blondies cool at least an hour to meld flavors and prevent a messy texture. Serve and enjoy!
