Ingredients

1 box (15.25 oz) cake mix (any flavor)
2 large eggs
½ cup (113g) unsalted butter, melted
1 teaspoon vanilla extract
1 ½ cups add-ins (chocolate chips, candies, nuts, etc.)

Step-by-Step Instructions

Preparing the Ingredients

Preheat your oven to 350°F and spray a 9×13-inch baking pan with nonstick spray, then set it aside while you prepare the batter.

Cooking Instructions

In a large mixing bowl, combine the cake mix, eggs, melted butter, and vanilla extract, then stir until a thick batter forms; next, fold in your chosen add-ins and spread the mixture evenly into the prepared pan, pressing it down with a spatula or your hands before baking for 17 to 20 minutes until the edges set, then allow the bars to cool completely before slicing.

Tips for Perfect Results

Common Mistakes to Avoid

Avoid overbaking because it can make the bars dry instead of soft and chewy, and also resist adding too many mix-ins since that can prevent the batter from setting properly.

Pro Tips for Better Flavor

For richer flavor, use high-quality butter and try combining two types of add-ins, such as chocolate chips and nuts, to create more texture and depth in every bite.

Serving and Storage

How to Serve

Serve these bars slightly warm for a soft texture or at room temperature for clean slices, and pair them with ice cream or a glass of milk for a comforting dessert.

How to Store Leftovers

Store leftover bars in an airtight container at room temperature for up to four days, or refrigerate them for longer freshness while reheating briefly to restore their soft texture.

Conclusion

Cake Mix Bars make baking simple, fast, and fun, so whether you’re preparing for a party or just craving something sweet, this recipe delivers consistent, crowd-pleasing results every time.
