Exploding Bonbons for "Oppenheimer" Fans

Going to the movies this weekend? You're probably going to see either the movie about everyone's favorite fashion doll or the one about the development of the atomic bomb, "Oppenheimer". For the filming of the latter, it's been rumoured that the director, Christopher Nolan, detonated an actual atomic bomb on the set of this anticipated film due to his dislike of using CGI effects. Nolan has been coy about how he actually got the effects he wanted for the film, but with the recipe below, it is possible to make an exploding dessert of sorts to enjoy before or after seeing this movie, with no radioactive elements required.

Ingredients:

1 box vanilla cake mix, plus the ingredients called for on the box
1 package each of red, blue, purple and green Pop Rocks candy
475 g white chocolate chips
180 g vanilla icing
10 mL refined coconut oil
cooking spray, for pan
3 drops red or orange food colouring (optional)

1. Preheat your oven to 177ºC and grease a 23-cm x 33-cm pan with cooking spray. 
2. Make the vanilla cake according to the directions on the box, pour the batter into the baking pan, and bake until a toothpick inserted in the center comes out clean, about 25 minutes. Remove the cake from the oven and let it cool completely.
3. Crumble the cake into a large bowl, making sure to break apart any large pieces. Add the icing and stir until everything is fully incorporated. Line a baking sheet with parchment paper, then place a wire cooling rack on the baking sheet. 
4. Roll the cake mixture into 20 small balls about the size of a ping-pong ball. Make a well in each cake ball with your thumb and transfer them to the wire rack. Pour the Pop Rocks into the wells and seal with more cake mixture, rolling one more time to make sure they are all round and sealed. Place the baking sheet in your freezer for 30 minutes, until bonbons are firm.
5. Combine the chocolate chips and coconut oil in a medium microwave-safe bowl. Microwave in 30-second increments, stirring in between. Spoon the melted white chocolate over the chilled bonbons until all are coated.
   
   For those with the ability to draw:
   
   • Mix the food colouring into the remaining white chocolate and transfer everything to a piping bag or a resealable plastic bag, then cut off the tip to create a small hole. Now you can decorate each cake ball with either a mushroom cloud or a rendering of either Fat Man or Little Boy.
6. Place the bonbons in the freezer for 10 minutes before serving.
