Tips & Variations

For extra texture, sprinkle chopped peanuts or walnuts over the frosting before it sets.

Use crunchy peanut butter for a nuttier bite.
Swap half the chocolate chips with white chocolate chips for a twist.

Storage

Store the frosted brownies in an airtight container at room temperature for up to 3 days. For longer storage, refrigerate for up to a week or freeze for up to 3 months. Reheat briefly in the microwave to soften before serving.

FAQs

Can I use natural peanut butter instead of regular peanut butter?

Yes, natural peanut butter works well, but it may alter the texture slightly. Choose a creamy variety for best results.

How do I know when the brownies are done baking?

Insert a toothpick in the center; it should come out with a few moist crumbs but not wet batter. The edges should look set and slightly pulling away from the pan.
