Recipe FAQs

How can I achieve fudgier brownies?

For a fudgier texture, bake the brownies slightly less than indicated until a toothpick shows moist crumbs.

Can I substitute walnuts with other nuts?

Yes, pecans or hazelnuts work well as alternatives to walnuts or you can omit nuts entirely for a nut-free version.

Is it necessary to melt the butter in the pan?

Melting butter directly in the baking pan simplifies mixing and helps quickly combine ingredients for a smooth batter.

What is the best way to mix the dry ingredients?

Sift the flour, cocoa powder, salt, and baking powder over the wet mixture and gently fold with a spatula to maintain lightness.

How should I store leftovers to maintain freshness?

Store brownies in an airtight container at room temperature for up to three days or refrigerate for longer freshness.

Can chocolate chips be added for extra richness?

Yes, folding in semisweet chocolate chips adds pockets of melty richness without changing texture significantly.
