Recipe FAQs

How can I achieve fudgier brownies?

For an extra fudgy texture, slightly underbake the brownies by checking them a few minutes before the full baking time ends. The center should have moist crumbs.

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 variant.

Is it necessary to melt butter directly in the baking pan?

Melting butter directly in the pan helps combine ingredients smoothly without extra dishes, but melting separately also works.

What’s the best way to check doneness?

Insert a toothpick into the center—if it comes out with a few moist crumbs, the brownies are ready without overbaking.

How should I store leftover brownies?

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