Preheat your oven to 350°F and line two baking sheets with parchment paper or silicone baking mats. This ensures even heat circulation and prevents sticking, which is especially important for these delicate strawberry cookies.
In a large mixing bowl, combine the strawberry cake mix, room temperature eggs, vegetable oil, and vanilla extract. Stir until just combined—the batter should be thick and homogeneous with no streaks of dry mix remaining. The room temperature eggs help create a better emulsion with the oil, resulting in a softer, more tender cookie texture.
Gently fold the chocolate chips into the dough from Step 2 using a spatula until evenly distributed throughout. I prefer Ghirardelli semi-sweet chips because they add a rich, slightly bitter contrast that balances the sweetness of the strawberry cake beautifully.
Scoop 2 tablespoons of dough and roll into a ball, then place on the prepared baking sheet about 2 inches apart. Using the bottom of a measuring cup or spoon, gently flatten each dough ball into a 1/4-inch thick disc. Leave them slightly thicker than typical cookies—they'll rise as they bake and stay chewy in the center.
Bake for 12 minutes, until the edges are just set and beginning to turn golden, but the centers still look slightly underbaked and soft. The cookies will continue to cook on the hot pan after removal from the oven, so don't overbake or they'll become too dry. Let them cool on the baking sheet for 2-3 minutes before transferring to a wire rack.
