Directions
<ol class="no-list-style"><li class="MethodStepper"><h4 class="step-title">Step 1</h4>In a large mixing bowl, cream together the softened butter, brown sugar, and granulated sugar until light and fluffy (about 2-3 minutes). This creaming process incorporates air into the mixture, which helps create a tender cookie texture.</li><li class="MethodStepper"><h4 class="step-title">Step 2</h4>Add the egg and vanilla extract to the butter-sugar mixture and beat until fully incorporated and smooth, about 1 minute.</li><li class="MethodStepper"><h4 class="step-title">Step 3</h4>In a separate bowl, whisk together the flour, baking soda, and salt. Gradually add the dry ingredients to the wet mixture, mixing on low speed just until combined. Overmixing develops gluten, which can make cookies tough rather than tender.</li><li class="MethodStepper"><h4 class="step-title">Step 4</h4>Gently fold in the chocolate chunks using a rubber spatula, distributing them evenly throughout the dough. Cover the bowl with plastic wrap and chill the dough for at least 30 minutes in the refrigerator. This chilling time allows the flour to hydrate and prevents excessive spreading during cooking.</li><li class="MethodStepper"><h4 class="step-title">Step 5</h4>Cut a piece of parchment paper to fit the bottom of your air fryer basket. Some air fryers come with perforated liners specifically designed for them, which work wonderfully for cookies as they allow air circulation.</li><li class="MethodStepper"><h4 class="step-title">Step 6</h4>Using an ice cream scoop or tablespoon, portion the dough into 40g balls (about 1½ tablespoons each). Place 3-4 dough balls on the parchment paper in the air fryer basket, leaving at least 5cm between each to allow for spreading.</li><li class="MethodStepper"><h4 class="step-title">Step 7</h4>Set your air fryer to 160°C and cook the cookies for 6-8 minutes. The cooking time may vary depending on your air fryer model, so keep a close eye on your first batch. The cookies should be golden around the edges but still soft in the center when done.</li><li class="MethodStepper"><h4 class="step-title">Step 8</h4>Carefully remove the cookies from the air fryer using a spatula and allow them to cool on the parchment paper for 3 minutes before transferring to a wire rack. The cookies will continue to set as they cool, so resist the urge to handle them too soon!</li><li class="MethodStepper"><h4 class="step-title">Step 9</h4>Repeat with the remaining cookie dough, using fresh parchment paper for each batch. Let the cookies cool completely before storing in an airtight container for up to 5 days – though I doubt they'll last that long!</li></ol>
