1st step– Coconut filling:

  • 3 C flaked coconut
  • 1 (14 oz.) can sweetened condensed milk
  • 1 tsp. vanilla
  • 1/4 tsp. almond extract

To make the tunnel cake:

Pour half the batter into the Bundt pan.  Spoon the coconut filling onto the batter, leaving batter on both the inside and outside of the filling.  Sprinkle the chopped pecans on top of  the coconut filling.  Slowly, pour the remaining cake batter over the filling.
