- Preheat oven to 350 °F (180 °C). Grease and line an 8-inch (2L) square pan with parchment paper, so that the paper hangs over the sides of the pan.
- Stir oats graham crumbs and salt to combine, then stir in melted butter. Press crumbly oat mixture into prepared pan. Sprinkle Skor bits evenly on top, followed by chocolate chips and sliced almonds. Pour condensed milk evenly over pan (it will sink in as it bakes) and bake for 30 to 40 minutes, until top is golden brown and edges are bubbling. Cool to room temperature, then chill for at least 4 hours before slicing.
