How to Make Peanut Butter Truffle Brownies

Now for the fun part! Let’s make these delicious Peanut Butter Truffle Brownies.

First, preheat your oven to 350 degrees. Line a 9×9 inch pan with parchment paper or foil and lightly grease with non-stick cooking spray.

Mix brownie mix with ingredients listed on package. Pour in pan and bake according to directions on the box. Allow to cool completely.

To make the peanut butter layer, mix together butter, peanut butter, powdered sugar, and milk in large bowl. Spread peanut butter mixture overcooked brownies.

In small microwavable bowl, microwave chocolate chips and butter uncovered 30 to 60 seconds; stir until smooth. Let cool for a few minutes. Spread over filling and add sprinkles.

Refrigerate brownies for 30 minutes or until chocolate is set. Cut into squares and enjoy!

Tips for Making the Best Brownies

Line your baking dish with parchment paper or foil before baking. This will make it super easy to lift them out of the pan and slice for serving.
I recommend using regular creamy peanut butter instead of natural or sugar free when making these brownies.
For best results, we recommend keeping these brownies chilled. Store in airtight container for up to 5 days or freeze for up to 3 months.
Cut bars into smaller squares especially if you are making them for a lot of people. These brownies are very rich. Plus, people can always go for seconds.
