Dreamy French Silk Pie Bars

Ingredients
  

For the Oreo cookie base:

  • 1 ½ cups finely ground Oreo cookie crumbs, 17 cookies (6.75oz, 191g)
  • 4 tablespoons melted butter (2oz, 57g)

For the filling:

  • 4 ounces unsweetened chocolate, melted and cooled (113g)
  • 1 cup unsalted butter, melted and cooled (8oz, 227g)
  • 1 ⅓ cups superfine sugar (10.6oz, 300g)
  • pinch of salt
  • 1 teaspoon vanilla
  • 1 teaspoon instant coffee granules
  • 4 large eggs at room temperature

For topping:

  • Lightly sweetened whipped cream
  • Semi-sweet chocolate shavings or curls

Instructions
 

For the Oreo cookie base:

  • Preheat oven to 350 degrees F
  • Prepare an 8 inch by 8 inch baking pan by lining the pan with aluminum foil leaving an overhang coming up the sides to easily lift the bars out of the pan. Alternatively use a non-stick, removable bottom pan. Spray the inside with cooking spray.
  • Combine the Oreo cookie crumbs and the melted butter. Press into the bottom of baking pan.
  • Bake in 350 degree F oven for 5-8 minutes until set.
  • Remove from oven and let cool. Let chill in freezer while preparing the filling.

For the filling:

  • In the bowl of a stand mixer with the paddle attachment, beat the softened butter and the sugar on medium-high for 5 minutes until pale in color and light and fluffy, stopping to scrape down the sides of the bowl half-way through.
  • Add the salt, vanilla, coffee granules, and cooled, melted chocolate and beat for another 5 minutes. Scrape down the sides of the bowl.
  • Using the whisk attachment, one by one, add the eggs and beat for a full 5 minutes after the addition of each egg, for a total of 20 minutes. Beating the full 20 minutes is essential. Scrape down the sides of the bowl before the addition of each egg.
  • Pour the filling into the prebaked crust and refrigerate for several hours or overnight.
  • Before serving, top with lightly sweetened whipped cream and chocolate shavings or curls.
  • Store the French Silk Pie Bars in the refrigerator.
