Ingredients

  • Crust:
  • 1/2 cup butter
  • 1 cup water
  • 1 cup flour
  • 4 large eggs
  • Cream Filling:
  • 2 3.125 ounce packages instant vanilla pudding
  • 2 1/2 cups milk
  • 6 ounces Cool Whip 3/4 of an 8 ounce Cool Whip
  • 1 teaspoon vanilla
  • Topping:
  • 1 and 1/2 squares unsweetened chocolate 1.5 ounces
  • 2 tablespoons butter
  • 2 tablespoons milk
  • 1 cup powdered sugar
  • 1 teaspoon vanilla

Instructions

  • Crust:
  • Preheat oven to 400 degrees.
  • Boil together the water and butter
  • Stir in 1 cup flour until throughly combined and cook until ball forms and it pulls away from the sides.
  • Remove from the heat.
  • Add in eggs one at a time, mixing throughly by hand after each. (I use a wooden spoon or my King Arthur bread dough whisk.)
  • Drop by spoonfuls into a ring on a lightly grease cookie sheet or round pizza pan.
  • Bake at 400 degrees for 40-45 minutes or until the middle is dry. Sometimes it takes as long as 55 minutes, so watch very carefully towards the end.
  • Check with a cake tester to make sure it's dry inside.
  • Cool completely on a wire rack.
  • Cut in half horizontally with a serrated or electric knife.
  • Cover the bottom half with filling, put the top half back on.
  • Filling:
  • Using an electric mixer or whisk, mix the instant vanilla pudding with milk for two minutes.
  • Gently fold in the Cool Whip and vanilla with a rubber spatula.
  • Rich Chocolate Frosting:
  • Melt chocolate in a saucepan over low heat.
  • Add in butter 'til it melts.
  • Remove from heat.
  • Stir in milk 'til combined.
  • Stir in powdered sugar and vanilla.
  • Pack frosting in a pastry bag and pipe with a decorating tip (or use a ziploc bag with snipped corner), going around the entire cake.
  • Refrigerate for a short time 'til chocolate sets, cover in plastic wrap, then return to refrigerator.
  • Refrigerate leftovers. (If you have any!)

Notes

Make all at once, or in stages and construct it the morning you serve.
Use a pastry bag and decorating tip to pipe your chocolate icing, or snip a hole in the corner of a ziploc bag.
There will be lots of extra filling. Save it for another use or get out your spoon for a treat.
