Famous Chocolate chip cookies

0 Preheat oven to 350° degrees F.2. Cream together butter, shortening, sugars, eggs and vanilla.3. Add salt and baking soda.4. Now your flour, allowing the mixture to fully absorb and incorporate it. It is VERY important that you measure the flour precisely as it will affect the texture of the cookies if it is off. I like to scoop the flour and then use a butter knife to scrape it level. 5. Chop your Symphony bars and add in, or a bag of milk chocolate chips. We also love mini M&M's! Mix until evenly distributed.6. Add cookie dough scoops to a cookie sheet WITHOUT non-stick spray, or use a parchment sheet to line it. 7. Drop a heaping tablespoon's-worth of dough for each cookie onto baking sheet. (12 cookies per sheet)8. Bake for 10-11 minutes or until just barely golden around the bottom edge of the cookie. You want the cookies to be very soft inside! Watch them closely near the end. Ovens all bake differently and most need calibrated so check them at the end of the 10 minutes. Allow to cool for a few minutes to set, then transfer to a cooling rack. These cookies are fantastic warm, but also stay very soft in a ziplock bag. They freeze very well in a ziplock bag if you need to make them ahead. Recipe makes just over 2 1/2 dozen.
