Warning: These Peanut Butter Brownie Bites Are Addictive
Chocolate Peanut Butter Brownie Bites? Yes
If you’re the kind of person who always chooses chocolate and peanut butter on a dessert menu, these Chocolate Peanut Butter Brownie Bites are going to be dangerous in the best possible way. Imagine a rich, fudgy brownie baked in bite-sized form, with a soft center that holds a pool of warm, melted peanut butter. They’re decadent, easy to make, and just the right size to “accidentally” eat more than one.
These brownie bites are ideal for parties, game days, potlucks, or holiday dessert trays. They look impressive, but the process is straightforward: melt, mix, bake, press, and fill. You can top them with extra chocolate chips for a bakery-style finish, or even a sprinkle of flaky salt if you like that sweet-salty combo.
What I love most about this recipe
The brownie base is made in a single bowl with simple ingredients you probably already have on hand: butter, sugar, chocolate chips, an egg, and a few pantry staples. The batter is baked in a muffin tin so each brownie has crisp edges, a soft middle, and a perfect little well for that peanut butter filling. It’s like a cross between a brownie, a peanut butter cup, and a lava cake in mini form.
If you’re looking for a reliable, crowd-pleasing dessert that delivers big flavor in a small package, add these chocolate peanut butter brownie bites to your must-bake list.
What You’ll Need & Why
Full printable recipe card at the bottom of this post
-
Granulated sugar – Sweetens the brownies and helps create that classic fudgy texture.
-
Butter, softened – Adds richness and moisture to the brownie base. Softened butter melts easily and combines well with the sugar.
- Semi-sweet chocolate chips or a chocolate bar – These are melted into the batter to create a rich, chocolatey base.
-
Large egg – Binds the batter together and helps the brownies set while staying fudgy in the center.
-
Vanilla extract – Enhances the chocolate flavor and adds warmth and depth.
-
All-purpose flour – Provides structure so the brownie cups hold their shape in the muffin tin.
-
Baking soda – Gives just a slight lift so the brownie bites aren’t too dense.
-
Milk chocolate chips – Folded into the batter at the end for extra pockets of melty chocolate in each bite.
-
Creamy peanut butter – The star of the filling. When melted and spooned into the center of each brownie bite, it creates a smooth, creamy peanut butter core.
Tips & Tricks for Perfect Brownie Bites
-
Don’t overbake.
For a fudgy texture, bake just until the tops are set. The centers should still be soft; they’ll firm up slightly as they cool. -
Cool the batter briefly before adding milk chocolate chips.
If the batter is too hot, the milk chocolate chips will melt completely rather than forming small pockets of chocolate. -
Grease the muffin tin well.
If you’re not using liners, be sure to grease the pan thoroughly so the brownie bites release easily. -
Customize the topping.
Add a sprinkle of flaky sea salt, mini chocolate chips, or chopped peanuts on top of the peanut butter for extra texture and flavor. -
Serve warm for maximum gooey factor.
These are wonderful at room temperature, but slightly warm brownie bites with soft peanut butter centers are next-level.
FAQ – Chocolate Peanut Butter Brownie Bites
1. Can I use natural peanut butter?
You can, but regular creamy peanut butter (the no-stir kind) works best. Natural peanut butter can be oilier and may not set as nicely in the centers.
2. Can I use a mini muffin tin instead?
Yes. If you use a mini muffin tin, reduce the baking time and start checking for doneness around 10–12 minutes. You’ll also use a little less peanut butter in each center.
3. How do I store these brownie bites?
Store them in an airtight container at room temperature for up to 3 days, or in the refrigerator if you prefer a firmer peanut butter center. Let them come to room temperature or warm slightly before serving.
4. Can I freeze them?
Yes. Once completely cooled, place the brownie bites in a single layer on a baking sheet to freeze, then transfer to a freezer-safe bag or container. Freeze for up to 1–2 months. Thaw at room temperature.
5. My brownie bites didn’t cave in the middle. What did I do wrong?
Nothing at all. Some batches naturally sink a little; others don’t. If they stay domed, just use the back of a spoon to gently press the centers down while they’re still warm to create a well for the peanut butter.

Chocolate Peanut Butter Brownie Bites
Ingredients
- 3/4 cup granulated sugar
- 1/4 cup butter softened
- 1 tablespoon water
- 1 cup semi-sweet chocolate chips or chocolate bar
- 1 large egg
- 1/2 teaspoon vanilla extract
- 1 cup all-purpose flour
- 1/4 teaspoon baking soda
- 3/4 cup milk chocolate chips
- 1/2 cup creamy peanut butter
Instructions
- In a microwave-safe bowl, combine the granulated sugar, softened butter, and water. Microwave in 45-second increments, stirring in between, until the butter is melted and the mixture is hot.
- Add the 1 cup semi-sweet chocolate chips to the warm mixture and stir until the chocolate is completely melted and smooth. If needed, microwave for a few more seconds and stir again.
- Stir in the egg and vanilla extract until the mixture is well combined.
- Add the all-purpose flour and baking soda, mixing just until the batter is combined and smooth. The batter will be thick and glossy.
- Allow the batter to cool slightly at room temperature for about 5–10 minutes so it is not too hot when adding the milk chocolate chips.
- Fold in the 3/4 cup milk chocolate chips until evenly distributed.
- Preheat the oven to 350°F (175°C). Grease a muffin tray or line with paper liners. Spoon the batter into the muffin cups, filling each about 3/4 full.
- Bake for 14–16 minutes, or until the tops look set and a toothpick inserted near the edge of a brownie comes out mostly clean with a few moist crumbs.
- Remove the muffin tray from the oven and let the brownie bites cool in the pan for about 5 minutes. If the centers do not naturally sink, gently press the center of each brownie with the back of a tablespoon to create a small well.
- Place the creamy peanut butter in a microwave-safe bowl and microwave in short bursts until melted and smooth.
- Spoon about 1 tablespoon of melted peanut butter into the center of each brownie bite, filling the well. Top with additional chocolate chips if desired.
- Allow the brownie bites to cool until the peanut butter has thickened slightly. Serve warm or at room temperature.
Notes
- For the fudgiest texture, do not overbake the brownie bites; remove them as soon as the tops are set and the edges are just done.
- Allowing the batter to cool slightly before adding the milk chocolate chips helps prevent them from melting completely into the batter.
- You can use a mini muffin tin to make smaller bites; just reduce the baking time and start checking around 10–12 minutes.
- Store leftover brownie bites in an airtight container at room temperature for up to 3 days, or refrigerate for a firmer peanut butter center. They can also be frozen for longer storage.
