Remove the ganache from the freezer.
Spoon an approximately 1/2-inch thick layer of batter into the bottom of each greased ramekin.
Using a 1.5 inch wide melon baller (or any spoon will do), scoop out about a heaping tablespoon of ganache and drop into the center of each ramekin on top of the batter.
Spoon the remainder of the batter over top of the ganache, so that each ramekin is about ¾ of the way full.
Place the ramekins onto a cookie sheet and place in the oven for 25 minutes. You will know they’re done when the top of the cakes spring back when pressed gently and are very slightly cracked.
Carefully remove the cakes from the oven and place on a heat-safe, flat surface.
Allow to cool for about 15 minutes, then very carefully, one by one, place a plate on top of each ramekin, turn the ramekin upside down and gently pull up on the ramekin so that the cake slides out onto the plate.
Garnish with vegan, soy-free vanilla ice cream and sprinkle with powdered sugar, cocoa powder or cinnamon.
Serve immediately.
