When I need a last-minute dessert that still feels fun enough for a casual get-together or movie night, this easy 3-ingredient cookie mix bake is exactly the kind of shortcut I reach for. It turns a bag of dry unbaked chocolate chip cookie mix powder into a warm, scoopable dessert bar with almost no prep, and it has that cozy homemade-cookie flavor without the usual measuring and mixing marathon. It is the kind of simple oven bake that feels especially fitting for National Chocolate Chip Cookie Day, and it is perfect for busy nights when you want something sweet fast.
Serve this dessert warm with vanilla ice cream, whipped cream, or a drizzle of chocolate syrup if you want to dress it up a little. Fresh strawberries or raspberries add a nice contrast to the rich cookie flavor, and a cold glass of milk or hot coffee makes it even better. If you are bringing it to a potluck, cut it into squares once cooled slightly, or serve it straight from the casserole dish for a more casual spoon-and-scoop dessert.
3-Ingredient Oven Baked Chocolate Chip Cookie Mix Dessert
Servings: 8
Ingredients
1 package dry unbaked chocolate chip cookie mix powder
1/2 cup melted butter
2 large eggs
Directions
1. Preheat the oven to 350°F and lightly grease an oven-safe ceramic casserole dish.
2. Pour the dry chocolate chip cookie mix powder into the casserole dish. Add the melted butter and eggs, then stir until everything is fully combined into a thick cookie batter.
3. Spread the batter evenly in the dish so it bakes in a uniform layer.
4. Bake for 22 to 28 minutes, or until the top is golden brown and the center is just set. Do not overbake if you want a soft, gooey texture.
5. Let it cool for 10 to 15 minutes before scooping or cutting into squares. Serve warm.
Variations & Tips
Extra Gooey Version: For an even softer center, start checking the dessert at the 20-minute mark and pull it from the oven as soon as the edges are set and the middle no longer looks wet.
Add-Ins: If you do not mind going beyond three ingredients, a handful of chopped nuts, extra chocolate chips, or toffee bits can make this feel a little more bakery-style.
Make It Neater: If you want cleaner squares instead of spoonfuls, let the dessert cool longer before slicing. It will still be soft, but the portions will hold together better.
Best Dish Size: An 8-inch square baking dish or similarly sized small casserole dish works well here. A larger dish will make the dessert thinner and bake faster, so keep an eye on it.
Storage: Cover leftovers tightly and keep them at room temperature for up to 2 days, or refrigerate for up to 4 days. A quick few seconds in the microwave brings back that fresh-from-the-oven texture.
