Directions
<ol class="no-list-style"> <li class="MethodStepper"> <h4 class="step-title">Step 1</h4> Measure out all your ingredients before starting. Line your round cake pan with parchment paper, leaving overhang on the sides to easily lift the cookie pie out after baking. Lightly grease any exposed areas of the pan. Ensure your pan fits comfortably in your air fryer with room for air circulation. </li> <li class="MethodStepper"> <h4 class="step-title">Step 2</h4> In a large mixing bowl, cream together the softened butter, granulated sugar, and brown sugar until light and fluffy, about 3-4 minutes. This extended creaming process incorporates air into the mixture, creating a lighter texture in the final cookie pie. </li> <li class="MethodStepper"> <h4 class="step-title">Step 3</h4> Add the egg, egg yolk, and vanilla extract to the butter-sugar mixture. Beat until completely incorporated and the mixture looks smooth and glossy. The extra egg yolk adds richness and contributes to that perfect chewy texture. </li> <li class="MethodStepper"> <h4 class="step-title">Step 4</h4> In a separate bowl, whisk together the flour, baking soda, and salt. Gradually add this dry mixture to the wet ingredients, mixing on low speed just until combined. Over-mixing will develop the gluten in the flour and result in a tougher cookie pie, so be gentle! </li> <li class="MethodStepper"> <h4 class="step-title">Step 5</h4> Fold in the chocolate chunks or chips by hand using a spatula, reserving about 2 tablespoons for topping. Make sure the chocolate is evenly distributed throughout the dough. </li> <li class="MethodStepper"> <h4 class="step-title">Step 6</h4> Press the cookie dough evenly into your prepared pan. The dough should be level but not compacted too firmly. Sprinkle the reserved chocolate chunks on top and gently press them into the surface. If using, sprinkle a small amount of flaky sea salt on top for that delicious sweet-salty contrast. </li> <li class="MethodStepper"> <h4 class="step-title">Step 7</h4> Preheat your air fryer to 160°C (320°F). This lower temperature (compared to conventional oven baking) prevents the outside from browning too quickly before the center is properly cooked. </li> <li class="MethodStepper"> <h4 class="step-title">Step 8</h4> Place the pan in the air fryer basket and bake for 18-20 minutes. The cookie pie is done when the edges are golden brown and set, but the center still looks slightly underdone – this will give you that perfect gooey middle! Remember that all air fryers cook differently, so start checking at the 15-minute mark. </li> <li class="MethodStepper"> <h4 class="step-title">Step 9</h4> Allow the cookie pie to cool in the pan for at least 15 minutes – this resting time is crucial as it allows the center to set slightly while still maintaining that wonderful molten quality. The residual heat continues the cooking process gently. </li> <li class="MethodStepper"> <h4 class="step-title">Step 10</h4> Using the parchment paper overhang, carefully lift the cookie pie out of the pan and transfer to a cutting board. For the perfect presentation, wait until it's just warm to the touch before slicing. For an extra indulgent dessert, serve with a scoop of vanilla ice cream while still warm! </li> </ol>
