Start by preheating your oven to 350°F (175°C). This ensures that your cookies bake evenly.
In a medium saucepan over low heat, melt the unsalted butter. Once melted, remove it from the heat and allow it to cool slightly.
In a large mixing bowl, combine the melted butter, light brown sugar, and granulated sugar. Use a hand mixer or stand mixer to beat the mixture until it's light and fluffy. Add in the eggs one at a time, mixing well after each addition. Finally, stir in the vanilla extract.
In a separate bowl, whisk together the all-purpose flour, baking powder, and salt. Gradually add the dry ingredients to the wet mixture, mixing just until combined. Be careful not to overmix.
Fold in the 16 ounces of semi-sweet chocolate chips and the 24 ounces of semi-sweet chocolate chunks. If you’re feeling indulgent, you can also add chopped pieces of a chocolate bar for an extra chocolatey experience.
Using a cookie scoop, drop heaping tablespoons of dough onto prepared baking sheets, leaving enough space between each cookie for spreading.
Bake in the preheated oven for 10-12 minutes, or until the edges are set and the centers are still soft. Allow the cookies to cool on the baking sheet for a few minutes before transferring them to a cooling rack.
Once cooled, serve these Triple Chocolate Chunk Cookies to friends and family, or treat yourself to a warm cookie straight from the oven.
