Here's the recipe for this chocolate cake with chocolate and vanilla filling:
1 box chocolate cake mix - follow box directions, except for the addition of 1/4 cup of sour cream blended into the batter.
1 chocolate pudding mix, prepared (I add 1 TBS of pure cocoa)
1 vanilla pudding mix, prepared (I add 1 tsp pure vanilla)
After cooking the two layers of cake, with sharp long knife, carefully cut layer.*
Fill with prepared chocolate pudding between one of the cakes. Do the same for the remaining cake with the vanilla pudding.
One 12 oz bag of chocolate chips
1 cup heavy cream
1 tsp vanilla
In microwave, carefully melt the chocolate chips with the heavy cream. Be very CAREFUL not to burn the chocolate chips. Add the vanilla and stir until completely smooth.
Frost the prepared and filled cake. Do the sides first and then the top.
*You can cut the layers of the cake with unwaxed dental floss.
