Step 3: Coat the rice crispy hill in chocolate.
You will also need to pull out the ramekin before you do this step.
With a sharp knife, cut jagged pieces of "land" right at the "shoreline" of the rice crispy hill. You can heat the knife to make it cut better.
Step 4: Test fit the rice crispy hill on the cake.
Test fit the pieces and trim to fit.
Remember where all the pieces went. Use a digital camera for this step.
Step 5: Frost the cake.
Top the cake with the hill and the jagged pieces of "land".
I microwaved a little of the frosting for 10 seconds so it was slightly warm and pourable. I poured it around the area of the ramekin opening, and let it dribble down the side of the hill.
