Recipe FAQs

How can I make the brownies fudgier?

Slightly underbake the brownies by removing them from the oven when a few moist crumbs remain on a toothpick inserted in the center. This retains their soft, fudgy texture.

Can I substitute walnuts with other nuts?

Yes, pecans or hazelnuts work well as alternatives. You can also omit nuts entirely for a nut-free option without affecting the core texture.

What pan size is recommended for baking?

A 9x13-inch (23x33 cm) baking pan is ideal to ensure even cooking and proper thickness of the brownies.

Is it necessary to use chocolate chips?

Chocolate chips are optional but add an extra chocolate burst. The brownies are delicious with or without them.

How should the brownies be cooled before serving?

Allow the brownies to cool completely in the pan before cutting to retain structure and achieve clean squares.
