Instructions

1. You can make a cake according to instructions listed on your cake mix box, but I added orange juice instead of water and used less oil. 
2. Preheat the oven on 350F and mix the cake mix until smooth in texture. Line the baking pan with parchment paper to prevent burning and bake for 12-15 minutes depending on your oven or until a toothpick comes out clean. 
3. Take it out of the oven, let it cool for 5-7 minutes and simply place the cake inside of the deep large bowl. Crumbled it with your fingers or you can put it in the food processor to make it easier on you. 
4. Add Nutella, you can add more if you like, mix the cake crumbles and Nutella with your hands because the warmth of your hands will make the cake crumbles and Nutella come together. 
5. Put coconut oil on palms of your hands (alternatively you can use any oil) and make balls one size smaller than a golf ball. Put them on the clean parchment paper and after you are done with all, place the tray with cake balls in the freezer for about 30 minutes, or even overnight just cover them with plastic wrap.  
6. Melt the chocolate with whipped cream, and butter until chocolate is smooth in texture. Don't burn it, just keep the temp. on low and stir until it becomes smooth and thick. 
7. Now, look at the pictures above. I added few frozen balls at one time in melted chocolate and with a spoon take one by one out with the help of the fork to get rid of extra chocolate. Place it on the parchment paper and let it dry for maybe 10 minutes. You can place them in the fridge, too. 
8. For extra topping, if you going to use topping for whole cake ball wait for 2-3 minutes so chocolate can get just a bit dry then crush the topping in your food processor, toss it on your work area and roll the ball on top of the topping of your choice, place in the container with the lid.
9. If you just going to use topping on top of the ball, brush the top of already dried chocolate cake ball with more chocolate and sprinkle the topping on top.
