Chocolaty brownie bites with light and fluffy peanut butter mousse filling are the perfect antidote to your peanut butter chocolate craving.

brownie bites with peanut butter mousse

I have a deep love of peanut butter pie. I find it to be creamy, peanut buttery perfection. The trouble with peanut butter pie-it’s not super portable. I was looking for a dessert that had all the good parts of peanut butter pie-the fluffy peanut butter filling! the chocolate! (ok, those were really the two main parts) but was easy to take to a party without the need for fussy things like plates and forks and knowing how to make ganache.

Enter: these brownie bites. We make it nice and easy by adapting a box of mix and pressing it into a mini muffin pan. Then, we’re going to use a 1/2 batch of our already awesome peanut butter pie filling to fill up those brownie bites so they become the perfect, two bite treat.

Can I use natural peanut butter?

No. Natural peanut butter is made from just ground peanuts. There is no added hydrogenated oil and (typically) no added salt or sugar. Now, for general eating, natural is probably the way to go, but for our purposes, we need the fat and the salt and the sugar to make it taste super good.

Do I need a piping bag/tip?

Nope! You can just dollop the peanut butter mousse onto your brownie bites with a spoon if that’s what you have. OR you can load your peanut butter mousse into a Ziploc baggie and snip the end off and pipe a swirl of the peanut butter mousse onto the brownie bites.

But, if you have a piping tip, go ahead and use it. It will make things just a little easier. (Don’t know how to use a piping bag/put a piping tip in your bag? Learn how here. I promise, it’s super easy)
