Preheat the oven to 325 degrees. Very lightly, grease an 8" square baking pan. Set aside. In a large bowl, empty oat bar mix and stir in all ingredients until the mix is evenly coated. Spread mixture evenly and firmly into the prepared pan. Bake bars for 25 minutes, or until edges are golden brown and oat bars are firm. Remove from oven and let cool.
Melt white chocolate in a small bowl in the microwave. Once melted, add Color Kitchen Natural Green Dye Packet into the chocolate and mix until green. Next, melt regular chocolate in a small bowl in the microwave. Using a spoon, drizzle melted chocolate back and forth on the bars. Cut bars into 1-inch by 4-inch pieces. Enjoy!
