The sky is the limit for add ins to a boxed brownie mix.  Since I love the taste of chocolate and peanut butter, I am using peanut butter morsels to give the brownie batter a Reese’s type of feeling.

Chopped pecans also add some extra crunch and texture.Plate of Rich chocolate brownies with peanut butter and pecans

Making these brownies is as simple as opening the brownie mix and adding it to a stand mixer with the extra ingredients printed on the box.  Today, I used a Betty Crocker Fudge Brownie Mix and added water, oil and eggs.

Just a quick mix and then in go the extra peanut butter chips and pecans and the mix is ready to bake! It took me all of 3 minutes!

The extra additions to the brownie mix added just a few minutes to the cooking time. I cooked mine for about 28 minutes in a 9 x 11″ pan lined with parchment paper. 

This paper makes it very easy to remove and cut the brownies after baking and there is no need for greasing the pan which saves more time and calories.

These rich fudge brownies have a deep, dark color. I can’t wait to take a bite to see how they taste with the add-ins!

Allow the brownies to cool completely before you cut them into squares. The addition of the peanut butter chips makes them extra moist, so you’ll want them to cool to cut them firmly.Rich chocolate brownies cut into squares

I cut these brownies into 18 portions, each with 298 calories.  They are very satisfying and quite addictive. I guarantee the plate will be clean when you take it back to the kitchen!
