FAQs

How do I make my brownies fudgier?

Use more butter and sugar while slightly reducing the flour. Avoid overbaking.

Can I use natural peanut butter?

Yes, but stir it well to prevent oil separation, as natural peanut butter can be runnier than regular peanut butter.

What size pan should I use?

An 8×8-inch pan is ideal for thick brownies, while a 9×13-inch pan will yield thinner brownies.

Can I double the recipe?

Yes, simply double the ingredients and use a larger baking pan. Adjust the baking time accordingly.

How do I know when the brownies are done?

Insert a toothpick into the center; it should come out with a few moist crumbs, not wet batter.

Can I add chocolate chips?

Absolutely! Stir in ½ cup of chocolate chips for extra chocolate flavor.

Should I refrigerate peanut butter brownies?

Not necessary, but it extends freshness. If refrigerated, let them sit at room temperature before serving.

Can I make these brownies without eggs?

Yes, use a flax egg (1 tablespoon ground flaxseed + 3 tablespoons water) as a substitute.

Why did my peanut butter sink?

If the peanut butter is too runny, it may sink. Try using a thicker peanut butter or slightly chilling it before swirling.

Can I use a boxed brownie mix?

Yes! Simply prepare the mix as directed and swirl in the peanut butter before baking.
