Recipe FAQs

How do I achieve fudgy brownies?

Underbaking slightly ensures a moist and fudgy texture rather than cakey. Keep an eye on the baking time to catch them when a toothpick shows moist crumbs.

Can I substitute walnuts?

Pecans or hazelnuts can replace walnuts for a different nutty flavor or omit nuts entirely for a nut-free option.

Is it necessary to line the pan?

Lining with parchment paper helps remove the brownies easily and keeps the pan clean for simple cleanup.

What’s the best way to mix ingredients?

After melting butter and stirring in sugar, add eggs one at a time with vanilla. Gently fold dry ingredients and nuts to maintain texture.

How should I store leftover brownies?

Store in an airtight container at room temperature for up to three days to maintain freshness and moisture.
