Why You’ll Love This Peanut Butter Brownie Cups Recipe

These brownie cups are incredibly satisfying. You get the full, rich flavor of brownies with a surprise peanut butter center that melts in your mouth. They are simple to make, yet look like something you’d find in a fancy bakery. Perfect for gifting, sharing, or hoarding for yourself (we won’t judge).

What Kind of Peanut Butter Works Best?

You want to stick with creamy peanut butter for this recipe. Natural peanut butter with oil separation won’t give you the same smooth filling. Brands like Jif or Skippy work great because they hold their texture and offer the perfect balance of salty and sweet that complements the brownie base beautifully.

Ingredients for the Peanut Butter Brownie Cups

To make the ultimate Peanut Butter Brownie Cups, you don’t need a ton of ingredients, but each one plays an important role in creating that chewy, chocolatey, nutty magic.

Brownie mix is the shortcut here, giving you a quick and reliable base that’s still delicious.

Eggs help bind everything together and contribute to the chewy texture.

Oil adds moisture and richness to the brownies.

Creamy peanut butter is the star of the show, creating that gooey, nutty center that contrasts the brownie layer perfectly.

Powdered sugar blends with the peanut butter to make a sweet and creamy filling that holds its shape.

Vanilla extract enhances the flavor of the filling and adds a touch of warmth.

How To Make the Peanut Butter Brownie Cups

Step 1: Prepare the Peanut Butter Filling

In a small bowl, mix creamy peanut butter, powdered sugar, and a splash of vanilla extract until smooth. Roll the mixture into small balls, about 1-inch in diameter, and place them on a tray. Chill in the freezer while you work on the brownie batter.

Step 2: Make the Brownie Batter

In a large bowl, combine the brownie mix, eggs, and oil. Stir until everything is well combined and you have a smooth, thick batter.

Step 3: Assemble the Cups

Preheat your oven and line a muffin tin with paper liners or spray with nonstick spray. Spoon a small amount of brownie batter into each muffin cup, about halfway full. Place a peanut butter ball in the center of each, then top with a little more brownie batter to cover.

Step 4: Bake to Perfection

Bake the brownie cups for 18-20 minutes or until the tops look set and slightly crackly. Let them cool in the pan for about 10 minutes, then transfer to a wire rack.

Step 5: Serve or Store

Enjoy warm for a melty center, or let them cool completely for an easy-to-pack treat.

How to Store and Serve Peanut Butter Brownie Cups

These peanut butter brownie cups serve about 12 people and can easily be doubled if you’re baking for a crowd. Once baked and cooled, you can store them in an airtight container at room temperature for up to 4 days. If you’d like them to last longer, keep them in the fridge for up to a week. They also freeze beautifully—just thaw at room temperature before serving.

For serving, you can enjoy them just as they are, or warm them up slightly for an extra gooey experience. A scoop of vanilla ice cream on the side wouldn’t hurt either.
