Ingredients

  • Butter: melted for rich flavor go for high quality unsalted butter

Instructions

Preheat the Oven:
Set your oven to three hundred fifty degrees Fahrenheit and grease a nine by thirteen inch baking pan so the bars release easily
Melt the Butter:
In a large microwave safe bowl melt the butter in thirty second intervals until fully liquid Let it cool for a minute so the eggs will not scramble when added
Whisk in the Eggs:
Add the large eggs to the butter and whisk together until smooth glossy and fully combined If using vanilla this is the best moment to stir it in for even flavor
Add the Cake Mix:
Pour the complete box of yellow cake mix into the wet mixture Stir with a sturdy spoon or spatula The dough will become thick and sticky which is key for chewy bars
Fold in the Chocolate Chips:
Add the entire bag of semi sweet chocolate chips Mix them in thoroughly so every bite gets a good amount of chocolate This step might take a little effort the batter is dense
Press into the Pan:
Spread the batter evenly into your greased pan You can use a spatula or your clean hands Smooth the top so it bakes up evenly golden
Bake:
Slide the pan into the oven and bake for twenty to twenty three minutes until the bars are just set in the center and golden at the edges For a thicker style in a smaller pan bake for twenty five to twenty eight minutes
Cool and Slice:
Let the bars cool for at least fifteen minutes before slicing This lets them firm up a bit and makes cutting neater Enjoy them warm for gooey chocolate or let them cool completely for cleaner slices

Cuisine: American

Yield: 20 Servings (One 9×13-inch tray, cut into 20 bars)

Dietary Categories: Vegetarian

Ingredients

→ Main Ingredients

01 1 stick (8 tablespoons) unsalted butter, melted
02 2 large eggs
03 1 box (15.25 ounces) yellow cake mix
04 1 bag (12 ounces) semi-sweet chocolate chips

→ Optional Ingredients

05 1 teaspoon vanilla extract
06 1/2 teaspoon salt

Steps

Step 01

Preheat oven to 350°F. Grease a 9×13-inch baking pan.

Step 02

In a large microwave-safe bowl, melt the butter in 30-second intervals until fully liquid. Allow to cool slightly to prevent cooking the eggs.

Step 03

Add eggs to the melted butter and whisk until mixture is smooth and fully combined. If using, add vanilla extract at this stage.

Step 04

Stir the yellow cake mix into the butter and egg mixture. Mix until a thick dough forms.

Step 05

Add the chocolate chips and stir until evenly distributed through the dough. If adding salt, include it with the chocolate chips.

Step 06

Spread the dough evenly in the prepared 9×13-inch pan using a spatula or clean hands. Smooth the surface.

Step 07

Bake for 20 to 23 minutes, until bars are golden around the edges and just set in the center. For thicker bars in a smaller pan, bake for 25 to 28 minutes.

Step 08

Let bars cool in the pan for 15 minutes before slicing. Serve warm and gooey or after fully cooling.

Notes

  1. Ensure melted butter is not hot before adding eggs to prevent them from scrambling.
  2. For chewier bars, avoid overbaking—edges should be golden and center just set.
