Ultimate Peanut Butter Brownie Bites: Your New Favorite Fudgy Mini Dessert
Are you ready for a dessert that combines two of the most beloved flavors in the world: rich chocolate and creamy peanut butter? These **Peanut Butter Brownie Bites** are an absolute dream come true for anyone with a sweet tooth. Imagine perfectly fudgy brownies, baked conveniently in mini muffin tins, each cradling a generous dollop of luscious, sweet peanut butter filling, reminiscent of your favorite peanut butter cups. These aren’t just brownies; they’re delightful, bite-sized explosions of flavor, making them the ideal treat for parties, gatherings, or a personal indulgence.
Brownies hold a special place in my heart, and if you’ve explored my blog before, you know I have a deep passion for them. With nearly 40 brownie recipes shared, it’s clear I’m always on the hunt for the next best chocolate creation. Among them, recipes featuring peanut butter, like my Peanut Butter Stuffed Brownies, are truly my biggest weakness. There’s just something magical about that classic combination!
Growing up, dessert was a cherished tradition in our home almost every weekend. It was a rotating affair between classic Chocolate Chip Cookies or a batch of homemade brownies. The recipes were so frequently made that to this day, I can still recite them from memory. This nostalgic connection to simple, comforting desserts is what drives my love for creating new variations of these timeless treats.

Why You’ll Fall in Love with These Peanut Butter Brownie Bites
Another chocolate and peanut butter brownie recipe should come as no surprise given my history! These delectable bites first graced the blog almost six years ago, and it’s high time they received a fresh update and some renewed attention. It’s simply not right for such a fantastic recipe to be overlooked. These treats are far too good not to be made and shared!
What makes these **Peanut Butter Brownie Bites** truly special is their delightful balance. The rich, dense brownie base provides the perfect foundation, while the creamy peanut butter filling adds an unexpected layer of flavor and luxurious texture. They’re miniature in size but mighty in taste, offering just the right amount of sweetness to satisfy your cravings without overwhelming you.
Choosing Your Brownie Base: Box Mix or Homemade Fudginess?
For these bites, you have the flexibility to choose your brownie base. You can opt for your favorite store-bought box mix, which offers unparalleled convenience, or you can use my super easy and always reliable fudgy brownie recipe. Both options work perfectly well, yielding delicious results. The true magic, however, unfolds with the incredibly simple yet decadent peanut butter mixture that forms the core of these treats.
If you choose a box mix, follow the package instructions for preparation. For a homemade touch, our fudgy brownie recipe guarantees a dense, moist, and intensely chocolatey base that complements the peanut butter beautifully. Whichever route you take, ensure your brownie batter is well-mixed but not overmixed, to maintain that desirable fudgy texture.

How to Make Peanut Butter Brownie Bites: A Simple Guide
Be sure to scroll to the bottom of the post for the FULL PRINTABLE recipe card with exact measurements and detailed instructions.
- **Prepare Your Brownie Batter:** Begin by mixing together your chosen brownie batter. Whether it’s from a store-bought mix or your go-to Homemade Brownies recipe, aim for a smooth consistency. Preheat your oven to 350°F (175°C) and generously grease a mini muffin tin. This step is crucial to ensure easy removal of your delicate brownie bites.
 - **Fill the Mini Muffin Tin:** Carefully divide the brownie batter evenly among the cups of your mini muffin tin. Each cup should be about two-thirds full to allow for a slight rise. This recipe typically yields around 35 delightful little brownie bites, perfect for sharing (or not!).
 - **Bake and Cool:** Bake the brownies for approximately 10-12 minutes. You’ll know they’re done when a toothpick inserted near the edge comes out with moist crumbs, but not wet batter. It’s totally normal for the centers to sink in slightly after you remove them from the oven – this creates the perfect well for our creamy peanut butter filling! Allow them to cool completely in the tin before carefully removing them.
 - **Craft the Peanut Butter Filling:** While the brownies cool, prepare the star of the show: the creamy peanut butter mixture. In a medium bowl, combine creamy peanut butter, powdered sugar, softened butter, and a hint of vanilla extract. Mix until the mixture is perfectly smooth, thick, and utterly irresistible. This filling is super thick and creamy, much like the luscious center of a Reese’s Peanut Butter Cup.
 - **Fill the Brownie Bites:** Once the brownie bites are cool, gently scoop a heaping teaspoon of the peanut butter mixture into the sunken center of each brownie. You can use a small spoon or a piping bag for a neater finish.
 - **Garnish and Serve:** For an extra touch of sweetness and visual appeal, sprinkle a few mini chocolate chips over each peanut butter-filled brownie bite. They are now ready to be devoured!
 

Tips for Perfect Peanut Butter Brownie Bites
- **Don’t Overfill the Muffin Tins:** Filling the cups about 2/3 full prevents overflow and ensures a nice, even bake.
 - **Cool Completely:** It’s essential to let the brownie bites cool completely before attempting to fill them. Warm brownies will cause the peanut butter mixture to melt and become messy.
 - **Use Quality Ingredients:** Good quality creamy peanut butter (not natural, runny varieties unless specified) and fresh butter make a noticeable difference in the flavor and texture of the filling.
 - **Soften Butter for Filling:** Ensure your butter for the peanut butter filling is adequately softened for a smooth, lump-free mixture.
 - **Grease Your Tins Well:** Even non-stick mini muffin tins benefit from a good greasing or non-stick spray to prevent sticking.
 
Variations and Serving Suggestions
I crafted these in a mini muffin tin because, with the rich peanut butter filling, these treats are incredibly decadent; a small bite is often all you need to satisfy that craving. However, if you’re feeling adventurous or want a more substantial dessert, you can certainly bake a few in a regular-sized muffin tin. Just be prepared for a truly indulgent experience – you might want to have someone around to share it with, or not, that’s entirely up to you!
- **Salted Caramel Drizzle:** A light drizzle of salted caramel over the chocolate chips adds another layer of complexity.
 - **White Chocolate:** Swap out milk or dark chocolate chips for white chocolate chips on top.
 - **Sprinkles:** Add colorful sprinkles for a festive touch, especially for holidays or birthdays.
 - **Chopped Nuts:** For extra crunch, sprinkle some finely chopped peanuts or pecans on top.
 - **Peanut Butter Swirl:** Instead of just filling the center, you could swirl a thin layer of peanut butter through the brownie batter before baking for a marbled effect.
 
Storage Instructions
These Peanut Butter Brownie Bites are best stored in an airtight container at room temperature for up to 3-4 days, or in the refrigerator for up to a week. If you prefer them chilled, let them come to room temperature for about 15-20 minutes before serving to ensure the brownie is soft and the peanut butter filling is creamy.
