Recipe Q&A

How do I achieve fudgy brownies?

To keep brownies fudgy, avoid overbaking and slightly underbake them. This retains moisture and creates the desired dense texture.

Can I substitute walnuts with other nuts?

Yes, pecans or hazelnuts work well as alternatives and add their unique crunch and flavor to the brownies.

Is it important to melt the butter first?

Melted butter helps blend ingredients smoothly and contributes to the rich texture of the brownies.

Can chocolate chips be added?

Optional semisweet chocolate chips can be folded into the batter to add bursts of melted chocolate throughout.

How should brownies be cooled before cutting?

Let the baked brownies cool completely in the pan to set properly, preventing crumbling when cut into squares.

What pan size is recommended?

A 9x13-inch baking pan works best to ensure even baking and proper thickness of the brownie layer.
