  • 1 package 9 ounces short bread cookies (Trefoils)
  • 3/4 cup salted butter 170 grams
  • 3/4 cup packed light brown sugar 150 grams
  • 1 package 12 ounces semisweet chocolate chips
  • 1/2 to 3/4 cup sliced almonds toasted -- can chop if desired


  • Preheat oven to 350°. Line a 15x10 inch rimmed baking pan with nonstick foil.
  • Arrange cookies evenly across pan.
  • In a large microwave-safe mixing bowl (I used a Pampered Chef Batter Bowl), heat the butter until melted, then whisk or stir in brown sugar.
  • Microwave 2 minutes, stirring every 30 seconds, until mixture is slightly thickened and looks more like a caramel sauce. It will still be fairly thin and pourable. Pour sauce over cookies, covering each completely.
  • Bake at 350 for 10 minutes or until caramel is very hot and bubbly. Remove from oven and let cool on a wire rack very briefly -- just about 3 minutes or until caramel settles down.
  • Sprinkle chocolate chips evenly over hot caramel. If desired, set another rimmed pan on top of the first rimmed pan to help hold in the heat. Let stand 5 minutes to soften chips, then spread softened chocolate chips over caramel. Sprinkle almonds over the top.
  • Refrigerate baking pan until chocolate and caramel have hardened, about 1 hour. Break or cut bark. Note: To toast nuts, bake in a shallow pan in a 350° oven for 5-10 minutes or cook in a skillet over low heat until lightly browned, stirring occasionally.
