Step 1: Mix Your IngredientsIn a large mixing bowl, combine the cake mix, eggs, and oil or melted butter. The magic happens when these simple ingredients come together! Mix until just combined – overmixing is the enemy of perfect texture. You'll notice the dough is thicker than cake batter but softer than traditional cookie dough.Pro tip: If you're using an electric mixer, use the lowest setting and stop as soon as all dry ingredients are incorporated. This preserves the perfect chewy texture that makes these cookies irresistible.Step 2: Add Your Personal TouchOnce your base dough is ready, fold in your chosen mix-ins. This is where you can get creative! Chocolate chips work wonderfully with chocolate or vanilla cake mix. Using a lemon cake mix? Add white chocolate chips and a bit of lemon zest for cookies reminiscent of our popular Great Gatsby Lemon Cake Recipe.Baker's secret: For even more flavor depth, chill your dough for 15-30 minutes. While not mandatory, this extra step allows the flavors to meld and makes the dough easier to handle.Step 3: Bake to PerfectionPreheat your oven to 350°F (175°C) and line a baking sheet with parchment paper. Scoop out tablespoon-sized portions of dough and place them about 2 inches apart on the baking sheet. For perfectly uniform cookies, use a cookie scoop or ice cream scoop.Bake for 9-11 minutes, until the edges are set but the centers still look slightly underdone. This ensures your cookies remain soft and chewy after cooling. Let them rest on the baking sheet for 5 minutes before transferring to a wire rack to cool completely.
