Instructions

Step 1: Line a 9x9 inch square baking pan with parchment paper. In a bowl, mix 1 1/2 cups rolled oats, 1 cup all-purpose flour, 1/2 cup packed brown sugar, and 3/4 cup melted unsalted butter until combined. Press this mixture firmly into the bottom of the prepared pan.
Step 2: In a saucepan over medium heat, combine 1 can (14 oz) sweetened condensed milk, 3/4 cup brown sugar, and 1/2 cup unsalted butter. Stir constantly for 8-10 minutes until the mixture turns a golden caramel color and thickens.
Step 3: Pour the caramel evenly over the oat base and sprinkle 1/2 cup chopped macadamia nuts on top. Refrigerate for 30 minutes to set.
Step 4: Melt 1 1/2 cups dark chocolate chips with 1 tbsp vegetable oil in a heatproof bowl over simmering water until smooth. Pour the chocolate over the caramel layer and spread evenly.
Step 5: Refrigerate the slice for at least 2 hours until fully set before cutting into squares and serving.
