Brownie Bites with Peanut Butter Frosting

In my opinion, there’s no better dessert combination than chocolate and peanut butter.  Have you ever had “one of those days” and needed a chocolate and peanut butter fix stat but didn’t have the time to whip something up from scratch?

Yeah, me too. That’s why I came up with this pantry baking recipe for mini Brownie Bites with Peanut Butter Frosting.

These brownie bites are semi-homemade but entirely delicious. The key to these is to start with a quality brownie mix. I used a 20-ounce Ghirardelli Brownie Mix.

For me, chocolate and peanut butter are a match made in heaven. There’s no other flavor combination that I love more than chocolate and peanut butter. This is perhaps why I have quite a few chocolate and peanut butter recipes on my site!
