Tunnel of Doom Cake~

Adapted from Brightideas.com


3 cups flour

2 1/2 teaspoons baking powder

1/2 teaspoon baking soda

1 teaspoon salt

3 1/2 cups Dove Dark Chocolate Promises (may use some milk chocolate) or just use your favorite dark chocolate bar, chopped, about 11 ounces total, divided

3/4 cup (1 1/2 sticks) butter, at room temperature

1 2/3 cups sugar

1 teaspoon vanilla bean paste or vanilla extract

3 eggs, at room temperature

1 cup milk

1/2 cup sour cream

1/4 cup Karo syrup (light corn syrup)

1/2 cup cream


Butter and flour a 12 cup capacity Bundt pan. Set aside. Preheat oven to 350º. 


Combine the flour, baking powder, baking soda and salt in a bowl and whisk to combine. Set aside.


Melt 1 3/4 cups dark chocolate in microwave (stop and stir every 30 seconds till melted and smooth). Set aside.


In a large bowl, beat the butter, sugar and vanilla till fluffy, then add the eggs, one at a time, till incorporated.


In another bowl (I used a glass measuring up with a spout), whisk together the milk and sour cream. With the mixer on low, alternately add the flour and the milk mixture into the batter, mixing till smooth.


Stir 1 cup of this batter into melted chocolate and set aside (chocolate should be warm not hot before adding batter). Set aside.


Spoon slightly more than half the plain batter into the bottom of the prepared Bundt pan. Add the chocolate batter (I aimed for the middle of the plain batter, but that may have made my chocolate layer extra heavy therefore making it sink), followed by the remaining plain batter.  Smooth top with offset spatula if needed.


Bake for 55-60 minutes or till toothpick inserted into the center comes out clean. Let cook for about 10 minutes then release from pan to cool completely on wire rack.


To make glaze, melt remaining chocolate with Karo syrup and heavy cream in the microwave for 1-2 minutes, stopping and stirring every 30 seconds till smooth and melted. Cool slightly. Place cake on the cooling rack over a baking sheet lined with parchment. Spoon glaze over cake.
