Cake Mix Bars: Step-by-Step Guide

Step 1: Preheat the Oven
Start by preheating your oven to 350°F (175°C). This ensures that your Cake Mix Bars bake evenly.
Step 2: Prepare the Baking Pan
Grease your 9×13-inch baking pan with a bit of vegetable oil or cooking spray. This will help prevent the bars from sticking.
Step 3: Combine the Ingredients
In a large mixing bowl, combine the white cake mix, eggs, vegetable oil, and sweetened condensed milk. Stir until all the ingredients are well incorporated and form a thick batter.
Step 4: Fold in the Chocolate Chips
Gently fold in the semisweet chocolate chips, making sure they’re evenly distributed throughout the batter.
Step 5: Add the Butter
Take the cubed salted butter and scatter it over the top of the batter. This will melt during baking and create pockets of buttery goodness throughout the bars.
Step 6: Bake
Pour the batter into the prepared baking pan and spread it evenly. Bake in the preheated oven for 25-30 minutes, or until a toothpick inserted into the center comes out clean or with just a few moist crumbs.
Step 7: Cool and Slice
Once baked, remove the pan from the oven and let it cool on a cooling rack for at least 15 minutes. Once cooled, slice into squares and enjoy your Cake Mix Bars!

Pitfalls & How to Prevent Them
While making Cake Mix Bars is straightforward, a few common pitfalls can arise:
- Overmixing: Be careful not to overmix the batter, as this can lead to dense bars. Mix just until combined.
- Baking Time: Keep an eye on the baking time. Every oven is different, so start checking for doneness at the 25-minute mark.
- Cooling: Allowing the bars to cool completely in the pan may result in them sticking. Transfer them to a cooling rack after about 15 minutes.
