Preheat the oven to 350 degrees.
Blend together the cake ingredients until well combined and smooth.
Fill the sections of a well greased muffin tin almost all of the way full with the batter.
Bake for 20-25 minutes, or until cooked through completely. Let cool to room temperature.
Remove the cakes from the muffin tin, and turn them upside down.
Use a sharp knife to cut a circular section from the center of each cake.
Press the inside of the cake down slightly with your fingers. Cut the cake part off of the sections removed, reserving onto the caps to place back on the cakes once filled.
Beat together the filling ingredients until light and fluffy.
Pipe the filling into the cupcakes, and place the cake caps back on top of them.
Add the chocolate chips and ΒΌ cup heavy whipping cream to a microwave safe bowl, and heat at 30 second intervals until completely melted and smooth.
Spoon the ganache over the filled cupcakes.
Chill the cupcakes until set, and then serve.
