Recipe FAQs

How can I make brownies extra fudgy?

Slightly underbake the brownies by checking with a toothpick and removing them while a few moist crumbs remain for a fudgier texture.

Can I substitute the walnuts?

Yes, pecans or hazelnuts can be swapped in, or you can omit nuts altogether for a nut-free version.

What is the best pan size for baking?

A 9x13-inch (23x33 cm) baking pan is recommended to ensure even baking and proper thickness.

How do I incorporate the ingredients directly in the pan?

Start by melting the butter in the pan, then stir in sugar before adding eggs and dry ingredients, folding gently to combine.

Are chocolate chips necessary?

Chocolate chips are optional, but they add extra pockets of melted chocolate for enhanced richness.

How should the brownies be cooled?

Allow the brownies to cool completely in the baking pan to set properly before cutting into squares.
