This legendary Tunnel of Fudge Cake is a show-stopping dessert featuring a dense, moist chocolate interior that remains soft and fudgy in the center. The batter is rich with butter, eggs, and cocoa, creating a tender crumb that holds its shape perfectly when inverted. The key to this cake is ignoring the standard doneness test; the center should remain slightly underbaked to create the signature “tunnel” effect. Finished with a simple chocolate glaze that drips down the sides, it offers a deep, satisfying chocolate flavor balanced by the crunch of walnuts. Perfect for holidays, celebrations, or any occasion where a dramatic, homemade chocolate cake is desired.

Directions
-
Preheat oven to 350 degrees F (175 degrees C).
-
Grease a 12-cup bundt pan or 10-inch angel food tube pan generously with butter or non-stick spray.
-
Dust the greased pan with flour, tapping out any excess.
-
In a large bowl, beat butter and sugar with an electric mixer on medium speed until light and fluffy, about 1 to 2 minutes.
-
Add eggs one at a time, beating well after each addition until fully incorporated.
-
Gradually add 2 cups of the powdered sugar, beating until well blended.
-
By hand, stir in the flour, 3/4 cup of the cocoa powder, and chopped walnuts; mix until just combined.
-
Spoon batter into the prepared pan and spread evenly.
-
Bake for 58 to 62 minutes. Do not use a toothpick test; the center will remain soft.
-
Cool the cake upright in the pan on a wire rack for 1 hour.
-
Invert the cake onto a serving plate and allow it to cool completely.
-
While the cake cools, make the glaze: In a small bowl, combine the remaining 3/4 cup powdered sugar, remaining 1/4 cup cocoa powder, and milk.
-
Mix the glaze ingredients until smooth and well blended.
-
Spoon the glaze over the top of the completely cooled cake, allowing it to drip down the sides.

Note
The "tunnel" effect relies on the center remaining underbaked. Do not extend baking time to achieve a dry center, or the cake will lose its signature fudge texture.
Accurate oven temperature is crucial. If your oven runs hot, the outside may overcook before the center sets properly. Consider using an oven thermometer.
Walnuts are essential for the texture and structural integrity of this specific recipe. If you have a nut allergy, this recipe may not succeed without significant substitution testing.
Store the cake tightly covered at room temperature for up to 3 days. The moisture in the center helps keep the cake fresh.
