Rice Krispies Treats are always a crowd favorite; this version highlights the best parts of rocky road ice cream - nuts, more marshmallows, and chocolate chips!
Melt the butter, the bag of marshmallows and cocoa powder together in a medium saucepan over low heat. Once melted, stir in the almond butter and remove from the heat.
Stir in the Rice Krispies until they are evenly coated with the sauce. Working quickly, stir in the remaining 2 cups marshmallows, walnuts and mini chocolate chips, mixing as gently as possible.
Pour the mixture into the prepared pan and press into an even layer. Use the back of a greased wooden spoon to press down firmly over the surface of the treats to ensure that they are packed down tightly.
Refrigerate for at least 30 minutes, or until set. Cut into bars and serve. Leftovers should be stored in an airtight container at room temperature or in the refrigerator (room temperature for softer, more gooey bars; refrigerator for firmer bars).
