Peanut Butter Brownie Bites – fudgy brownies baked in mini muffin tins and then filled with a creamy peanut butter mixture. Perfect bite to cure your sweet tooth!
Brownies are my ultimate weakness. If you have been here before, I am sure you know this. There are close to 40 brownie recipes on the blog. And a handful of them have peanut butter involved. Peanut Butter Stuffed Brownies might be my biggest downfall.
When I was growing up, pretty much every weekend we would have dessert. It would either be these Chocolate Chip Cookies or homemade brownies. The same recipe for both, all of the time. And to this day, I still have them both memorized because I have made them so many times.

So another chocolate and peanut butter recipe, that involves brownie shouldn’t come as a huge surprise to anyone. These first appeared on the blog almost 6 year ago. So today they are getting a little face lift. Plus, I am pretty sure no one has laid eyes on the recipe in years, and that is just no OK. They are too good not to be made.
You can use your favorite box mix brownies to make this, or you can use this super easy fudgy brownie recipe. Either is totally fine. The magic really happens with the peanut butter mixture. It is super thick, creamy, and kind of like the center of a Reese’s peanut butter cup.
How to Make Brownie Bites
Be sure to scroll to the bottom of the post for the FULL PRINTABLE recipe card.
- Start by mixing together brownie batter. You can use your favorite store bought mix or these classic super easy Homemade Brownies.
- Next divide the brownie batter evenly into a mini muffin tin. You will make about 35 little brownie bites.
- Then bake for about 10 minutes or until the brownies are cooked. When you take them out of the oven the centers should sink in some, that is totally normal! Let them cool completely and remove from the pan.
- Mix together peanut butter, sugar, butter and vanilla until it is nice and smooth.
- Fill the center of each brownie bite with a 1 heaping teaspoon of the peanut butter mixture.
- You can top with a few mini chocolate chips and they are ready to serve!
I made these in a mini muffin tin, because with the peanut butter they are definitely super rich; and a little bite is all you need. But if you want to go all out, make a few in a regular size muffin tin. You just might want to have someone around to share it with. Or not. That is totally up to you!
