Ingredient Notes
- Cake Mix: I use a boxed yellow cake mix for this version of chocolate chip cake mix cookie bars. Feel free to experiment with other flavors!
- Eggs: Room temperature eggs work best for smoother mixing, but you can use cold eggs if you’re short on time.
- Butter: I love the richness butter brings to these cookie bars. If needed, canola oil or vegetable oil are great substitutes.
- Chocolate Chips: We prefer milk chocolate chips in this recipe, but you can use virtually any flavor to suit your taste.
How to Make Yellow Cake Mix Cookie Bars
- Preheat the oven to 350° and spray a 9″ X 13″ baking pan with nonstick cooking spray.
- Melt the butter in the microwave or on the stove-top in a small saucepan over low heat.
- In a large bowl combine cake mix, eggs, and melted butter. Fold in the chocolate chips.
- Press into the prepared pan and bake for 16-19 minutes, or until the edges are golden brown.
- Cool completely before cutting and removing from the pan.
Tips
- A rubber spatula works best to mix the cookie dough and to spread it into the pan.
- Use your favorite brand of boxed cake mix for this recipe. Some brands, like Betty Crocker, come in 13.25 or 14.25-ounce packages, while others, like Pillsbury, are 15.25 ounces. All sizes will work perfectly!
Storage
Store cookie bars in an airtight container at room temperature for 3-5 days. As with all freshly baked goods these are best enjoyed within a couple of days. They will start to dry out after that.
How to Freeze Cake Mix Bars
For best results, wrap cooled bars in plastic wrap. Place them in a zip top bag. Freeze for up to 3 months.
Thaw in the refrigerator or at room temperature.
