Dinosaur Fossil Cake

Why didn’t anyone warn him?! At least he makes a handsome fossil. The preserved remains of prehistoric plants and animals, fossils occur when an organism is covered by rock and left undisturbed for millions of years, leaving an intact skeleton or imprint for paleontologists to study. That’s how we know about dinosaurs like our friend here, whose bones just happened to have been made of white chocolate. May he be as delicious as he was in life. Rest in cake.

Butter, for greasing the pans
Rich Chocolate Cake batter (see recipe below)
1 tub (16 ounces) chocolate frosting
1 package (about 14 ounces) chocolate sandwich cookies (Oreos)
1 box (about 14 ounces) graham crackers (Honey Maid)
2 bags (12 ounces each) white Candy Melts (Wilton) or white chocolate
Two 8-inch round cake pans
Cake leveler
Decorating bag
#2 decorating tip
Silicone dinosaur skeleton ice cube mold (Fred & Friends)

Preheat the oven to 350°F. Grease two 8-inch round cake pans.

Prepare the Rich Chocolate Cake batter.

Divide the batter between the prepared pans and bake until a wooden pick inserted in the center comes out clean, 30 to 35 minutes.

Let the cakes cool in the pans for 10 minutes. When the cakes are warm but not hot, remove them from the pans and place the cakes on a wire rack to cool completely.

Level off the tops with a cake leveler or large knife [Image A].

Top one layer with chocolate frosting and set the second layer on top of it [Image B] .

Frost the entire cake with chocolate frosting [Image C].

Time to decorate!:
Twist the Oreos apart and scrape off the filling. Using a blender or your hands, finely crush the chocolate cookies and graham crackers. Mix the crumbs together to look like dirt [Image D].

In the microwave or a double boiler, melt the white Candy Melts or white chocolate. Using a decorating bag fitted with a #2 tip, pipe the melted candy into the dinosaur skeleton mold [Image E].

Let the mold set for 20 minutes, and then pop the pieces out and place them on the top and sides of the cake. The frosting will act as an adhesive and keep the bones in place.

Sprinkle the cookie crumb dirt mixture between the bones to cover the entire cake [Image F].
