Trillionaire Bars, possibly the tastiest sweet treat recipe ever.

I discovered these a few weeks ago on Pinterest when I was investigating something tasty for the boys and I to bake together during Edie’s nap time. Something that daddy could indulge in when he came home and something that the boys would really like as a little treat.

The trillionaire bars are made up of four layers, each one more delicious than the last. We have a very chewy, fudgy brownies base, topped with gooey caramel which in turn is topped with an egg free totally delicious cookie dough mixture and finally spread with a rich, indulgent chocolate topping. Oh my goodness they were sublime. Literally SO tasty. I do have to warn you that; no matter how rich or sweet you like your treats, you really need to cut these rather small. They are far too sweet, rich and all-round-bad-for-you-divine that more than a couple of bites will make you queasy.

Here’s what you need:

Brownie layer

  • ½ cup butter, melted
  • 1 cup sugar
  • 1 cup unsweetened cocoa powder
  • ¼ teaspoon salt
  • ½ teaspoon vanilla
  • 2 eggs
  • ½ cup flour

Caramel layer

  • 1 tin carnations caramel

Cookie dough layer

  • ½ cup butter, softened
  • ¼ cup sugar
  • ½ cup brown sugar
  • 2 tablespoons double cream
  • ½ teaspoon vanilla
  • 1 cup flour
  • ⅛ teaspoon salt
  • 3/4 cup milk chocolate chunks/chips

Chocolate glaze

  • 1 cup semi sweet chocolate chips
  • 2 tablespoons heavy cream

Make the brownies first. Preheat the oven to GM3 and line a square 8×8 tin with foil. Add the butter and sugar together in a bowl and cream together. Add all the dry ingredients, vanilla and eggs, mixing together. This produces a really stiff, sticky batter. Place it in the pan and spread out until even, bake for 15 mins.

Once it’s out add the caramel, then place in the fridge to cool.

While that’s cooling make your cookie dough. Again, cream the butter and sugars. Add the flour, cream, vanilla and salt and mix until smooth. Once it’s smooth add your chocolate chunks.

Check on the brownie and caramel layers, touching the top to see if it’s still sticky or if it is only tacky now. Once it’s tacky, add dollops of the cookie dough, smoothing it out to form an even layer. return it to the refrigerator to chill.

Finally make your chocolate topping. Place the chocolate chunks and the cream into a pan and bring to a simmer, turn of the heat and stir them together until totally smooth. Allow to cool. Once the cookie dough is chilled and the chocolate spread is cooler, spread it over the top.

Finally leave to set for about 1 – 2 hours. If you can. Which you won’t be able to.

      Hi Geri, Gas mark 3 and double cream is the English term for thick cream, I believe American’s call it Heavy cream?
