Step 1: Preheat the Oven - Start by preheating your oven to 350°F (175°C). This ensures that your cookies bake evenly.
Step 2: Mix the Wet Ingredients - In a large mixing bowl, combine the softened unsalted butter, vegetable oil, and eggs. Whisk together until smooth and creamy.
Step 3: Add the Cake Mix - Gradually add the box of chocolate cake mix to the wet ingredients, mixing well until fully incorporated.
Step 4: Incorporate Baking Powder and Cocoa - Add the baking powder, unsweetened cocoa powder, and a dash of salt to the mixture. Whisk until everything is combined and no dry spots remain.
Step 5: Stir in Milk and Vanilla - Pour in the milk and vanilla extract, stirring until the batter reaches a smooth consistency. If you'd like to include chopped pecans, fold them in at this stage.
Step 6: Scoop and Bake - Using a cookie scoop or a tablespoon, drop rounded balls of dough onto a lined baking sheet, leaving enough space for spreading. Bake in the preheated oven for 10-12 minutes or until the edges are set and the centers are slightly soft.
Step 7: Cool and Frost (Optional) - Allow the cookies to cool on the baking sheet for a few minutes before transferring them to wire racks. If desired, you can frost the cooled cookies with a simple chocolate icing made from the remaining powdered sugar, cocoa powder, and a splash of milk.
