FAQs

Can I use natural peanut butter?

Yes, but stir it well beforehand. Natural peanut butter may create a slightly oilier swirl.

How do I get that fudgy texture?

Avoid overbaking. Remove from the oven when the center is just set, and let them cool fully to firm up.

Can I double the recipe?

Yes. Use a 9×13-inch pan and adjust baking time by adding 5–10 minutes.

Can I make these brownies without cocoa powder?

You can, but the cocoa enhances the chocolate flavor. If omitting, increase the chocolate slightly.

What kind of chocolate is best?

Semi-sweet or dark chocolate gives a rich flavor. Avoid milk chocolate, which may make the brownies too sweet.

Can I reduce the sugar?

Yes, but reducing it too much can affect texture. You may decrease each sugar by 1–2 tablespoons.

Do these brownies need to be refrigerated?

Not necessarily. They keep well at room temperature, but refrigerating can help them last longer.

How do I make cleaner cuts?

Chill the brownies first, then use a warm, sharp knife, wiping it clean between each cut.

Can I freeze them with the peanut butter swirl?

Yes. The swirl holds up well to freezing—just ensure they’re cooled and wrapped tightly.

Are these suitable for kids?

Absolutely. They’re a hit with children and adults alike thanks to the classic chocolate-peanut butter combo.
