Peanut Butter Truffle Brownies

When Sundays roll around, we find ourselves looking for a "fat-fat" recipe. (something gooey, something yummy, something not necessarily healthy) I found this one on The Girl Who Ate Everything, and it sounded good AND I just happened to have ALL the ingredients for them!

Brownie Base

1 box brownie mix

Filling1/2 cup butter, softened
1/2 cup creamy peanut butter (*I added a smidge more probably 3/4 cup)
2 cups powdered sugar

2 teaspoons milk

Topping

1 cup semisweet chocolate chips

1/4 cup butter

Heat oven to 350°F. Grease bottom only of 13×9-inch pan with cooking spray or shortening.
Mix brownie batter and bake according to package directions. Cool completely, about 1 hour.

In medium bowl, beat filling ingredients with electric mixer on medium speed until smooth. Spread mixture evenly over brownie base.

In small microwavable bowl, microwave topping ingredients uncovered on High 30 to 60 seconds; stir until smooth. Cool 10 minutes; spread over filling. Refrigerate about 30 minutes or until set. For brownies, cut into 9 rows by 4 rows. Store covered in refrigerator. (I take it out or the fridge about 15 minutes before serving. This allows the chocolate on top to soften a little)

***I didn't store my in the fridge 'cuz, frankly, there were not that many left to store and we all thought they were all better on Day 2. We will be making these again for sure!
