Step 1: Prepare the Dough: In a medium bowl, whisk together the gluten-free flour, baking soda, and salt. Ensure the mixture is well combined to avoid clumps.
Step 2: Cream Butter and Sugars: In a large bowl, cream together the softened butter, brown sugar, and granulated sugar until light and fluffy. This process incorporates air into the dough, contributing to a tender cookie texture.
Step 3: Incorporate Egg and Vanilla: Beat in the egg and vanilla extract until well combined. Ensure the egg is fully incorporated to create a smooth and emulsified batter.
Step 4: Combine Wet and Dry Ingredients: Gradually add the dry ingredients to the wet ingredients, mixing until just combined. Avoid overmixing, as this can result in tough cookies. The dough should be cohesive but not overworked.
Step 5: Add Chocolate: Stir in the semi-sweet chocolate chips and dark chocolate chunks until evenly distributed throughout the dough. The generous addition of chocolate ensures each cookie is packed with flavor.
Step 6: Chill the Dough (Optional): For best results, cover the dough and chill in the refrigerator for at least 30 minutes. Chilling the dough helps prevent excessive spreading during baking.
Step 7: Preheat and Prepare Baking Sheet: Preheat oven to 375F (190C). Line a baking sheet with parchment paper to prevent sticking and ensure easy cleanup.
Step 8: Scoop and Arrange Cookies: Drop rounded tablespoons of dough onto the prepared baking sheet, leaving about 2 inches between each cookie to allow for spreading.
Step 9: Bake: Bake for 10-12 minutes, or until the edges are golden brown and the centers are set. Monitor closely to prevent overbaking.
Step 10: Cool and Serve: Let the cookies cool on the baking sheet for a few minutes before transferring them to a wire rack to cool completely. Enjoy!
Optional Tips: For a richer flavor, use browned butter. To substitute, use a dairy-free butter alternative and dairy-free chocolate chips.
