  4. Reduce the speed to low and mix in the boiling water. Mix in the vanilla just until combined.
  5. Pour the batter into the prepared bundt pan and bake for 45-50 minutes, until a toothpick inserted in one the center of the cake comes out mostly clean.

  1. Stir rum into chilled pastry cream. Taste and add more if desired.
  2. Scoop pastry cream into a pastry bag fitted with a large round tip. Flip the cake upside down so that the bottom of the cake is facing up. Insert the tip into the cake and gently squeeze the decorating bag, pulling upwards until the cake swells slightly and the filling comes to the top. Continue to squeeze the custard into the cake all the way around, creating 11 or 12 “custard holes”. It will look like you are filling a large, round twinkie.
