FAQs
Can I use natural peanut butter for the swirl?
Yes, natural peanut butter can be used, but it may be a bit thinner and more oily. You might need to adjust the powdered sugar to achieve a smooth, spreadable consistency.
How can I tell when the brownies are done baking?
Check that the edges have set and insert a toothpick into the brownie away from the peanut butter swirl. It should come out with some moist crumbs but not wet batter.
