A delightful dessert bar combining rich chocolate and creamy layers for a perfect treat.
Preheat your oven to 350°F and prepare a 13 x 9 inch baking pan by spraying it with nonstick cooking spray.
Ensure the oven is fully preheated before baking for even cooking.
In a large bowl, combine the chocolate cake mix, one egg, and melted butter. Mix on low speed until well combined.
Mix just until combined to avoid overworking the dough.
Press the mixture evenly into the prepared pan to form the crust.
Use a spatula or your hands to press the crust evenly.
In another bowl, mix the remaining eggs, sour cream, brown sugar, and melted butter until smooth.
Ensure the mixture is smooth for a consistent topping.
Stir in the chocolate chips into the topping mixture.
Fold in the chocolate chips gently to distribute evenly.
Pour the topping mixture over the crust in the pan.
Spread the topping evenly for a uniform layer.
Bake in the preheated oven for 35 to 38 minutes, or until the top is set and lightly golden.
Check for doneness by gently shaking the pan; the center should not jiggle.
Allow the bars to cool completely in the pan before cutting into squares.
Cooling completely ensures clean cuts and proper setting.
Serve the bars as is or dust with cocoa powder for an extra touch.
Serve with a dollop of whipped cream for added indulgence.
