Tunnel of Fudge Cake is a brownie-like bundt cake with a tunnel of chocolate cheesecake filling.
This is one of the recipes Joan left behind. There was no description, just a recipe so I’m not sure where she was going with this other than lots of chocolate and sugar (appropriate don’t you think?).
I thought some aspects of the original recipe wouldn’t work so I tweaked it a little. Joan added boiling water to the chocolate chips. Water and chocolate usually don’t play well so I substituted milk for the boiling water. The original recipe also lacked any leavening so I added baking powder.
The chocolate ganache in this recipe is really thick. It comes out like frosting more than a glaze. If you want a more drippy look, double the amount of cream.
Joan also left out a chocolate filling. I didn’t realize this until after I made the first tunnel of fudge cake. As I started writing this post, I thought, “There’s no tunnel of fudge in the tunnel of fudge cake.” Even without the tunnel of fudge, the cake is moist, dark chocolate.
I’m not sure if she meant the whole cake to be a “tunnel of fudge” or if she just didn’t get around to making the filling. So, I decided to make up a filling for cake #2. I mixed some cream cheese with melted chocolate and added a little whipping cream.
This cake has a lot of sugar in it – white sugar, brown sugar and powdered sugar. Joan never skimped on sugar. We were rarely allowed sweets when we were kids so I think she wanted to make up for that as an adult. She always had more sugar than tea in her iced tea and, of course, she started this blog. Joan loved sugar and chocolate and this cake reflects that.
