Creating the Salted Espresso Chocolate Chunk Blondies is straightforward if you follow these simple steps:

1. Preheat Oven: Preheat your oven to 350°F (175°C). Grease a 9×13-inch baking pan or line it with parchment paper for easy removal.

1. Mix Wet Ingredients: In a large mixing bowl, combine the melted butter and brown sugar. Whisk until the mixture is smooth.

1. Add Eggs and Vanilla: Add the eggs, one at a time, mixing well after each addition. Stir in the vanilla extract until fully incorporated.

1. Combine Dry Ingredients: In a separate bowl, whisk together the flour, baking powder, espresso powder, and salt.

1. Mix Dry and Wet Ingredients: Gradually add the dry ingredients to the wet ingredients. Stir until just combined. Avoid overmixing to keep the blondies chewy.

1. Add Chocolate Chunks: Gently fold in the chocolate chunks to distribute them evenly throughout the batter.

1. Pour into Pan: Spread the batter evenly into the prepared baking pan. Smooth the top with a spatula.

1. Bake: Place the pan in the preheated oven and bake for 25-30 minutes, or until a toothpick inserted into the center comes out with a few crumbs but not wet batter.

1. Cool: Remove from oven and let the blondies cool in the pan for about 5-10 minutes. If using parchment paper, lift the blondies out for easier cooling.

1. Sprinkle with Sea Salt: Immediately sprinkle a pinch of sea salt over the top of the warm blondies before fully cooling.

1. Cut into Squares: Once completely cooled, cut into squares and serve.

These steps will guide you in creating these amazing blondies effortlessly.
