These are absolutely the chewiest, moistest, fudgiest brownies ever! I have tried adding so many different things to the batter, and they ALWAYS comes out great. They are also great without ANY add-ins! BUT by varying the add-ins, you can make different brownies every week (or day!!) SUPER EASY PREP! So, add "whatever floats your boat" and you will not believe how yummy they come out :) Oh, and the recipe doubles just fine--use a 9 x 13 inch pan instead and add a few more minutes of baking!
There are so many different versions of this wonderful combination. This is mine and I have used it for close to 20 years. This is DS favorite! The creamy peanut butter refers to a brand such as Jif or Skippy. I don't think a natural peanut butter will work as it is missing the oil Also, the margarine for the chocolate mixture is melted before adding to the chocolate chips. If water gets in the chocolate it well "seize".
