Line a 9-inch square baking dish with parchment paper. Set aside.
In a medium pot set over low heat, combine the peanut butter, honey, and 1/2 cup coconut oil. Stir until smooth and completely melted. Remove from heat and stir in oats and peanuts. Pour mixture into baking dish, spreading an even layer and pressing down firmly with the back of a spatula. Refrigerate for 10 minutes or until cool. Remove from fridge and sprinkle mini chocolate chips over the top of the mixture, pressing down lightly with the back of a spoon to set in granola. Return to refrigerator and chill 2 hours or until firm. Slice into small bars and remove from pan.
Melt semi-sweet chocolate chips and one teaspoon coconut oil in a heatproof bowl set over a pot of simmering water. Drizzle melted chocolate over bars and let set. Store granola bars in an airtight container in the refrigerator with wax paper separating the layers.
*You may also substitute the chocolate chips for a non-dairy alternative.
