Tips

Tip 1

Sift cocoa powder before adding if it appears lumpy to prevent texture issues in the finished brownies.

Tip 2

Cool completely before cutting for clean slices - rushing this step leads to crumbly, messy squares.

Tip 3

Tap chocolate chunks into the surface so they stay put during baking instead of sinking.

FAQ

Can I use dark chocolate chunks instead?

Yes, dark chocolate works well but will create a more intense, less sweet brownie. Adjust sugar if needed for your taste preference.

How long do these brownies keep?

Store covered at room temperature for up to 5 days or refrigerate for up to 1 week. They also freeze well for up to 3 months.

Can I make these in a different pan size?

A 9x9 pan works but reduces thickness and baking time to 20-25 minutes. Larger pans create thinner brownies with shorter bake times.
