Chewy caramel and toasted coconut layered over a buttery shortbread crust with a silky chocolate drizzle. These easy, bakery-style bars taste like your favorite Samoa cookies—perfect for parties, bake sales, or a sweet make-ahead treat.
Preheat oven to 350°F. Line an 8x8 inch baking pan with parchment, leaving overhang for easy lifting.
Make the crust: In a bowl, whisk flour, granulated sugar, and fine sea salt. Cut in 0.75 cup cold butter with a pastry cutter (or pulse in a food processor) until the mixture resembles coarse crumbs. Stir in vanilla.
Press dough firmly and evenly into the prepared pan. Bake 18 to 20 minutes until lightly golden at the edges. Set aside to cool slightly.
Toast the coconut: Spread shredded coconut on a sheet pan and bake at 350°F for 5 to 7 minutes, stirring once, until golden and fragrant. Cool.
Melt the chocolate: In a microwave-safe bowl, heat 1.0 cup chocolate chips with coconut oil in 20 to 30 second bursts, stirring until smooth. Reserve 0.25 cup chips for later drizzle.
Spread a thin, even layer of melted chocolate over the warm crust. Chill 5 minutes to set slightly.
Make caramel coconut: In a saucepan over low heat, melt caramels with heavy cream and 2.0 tbsp butter, stirring until smooth. Remove from heat; stir in toasted coconut and kosher salt.
Assemble: Dollop caramel-coconut mixture over the chocolate layer and press into an even layer with a spatula lightly greased or dampened to prevent sticking.
Drizzle: Melt remaining 0.25 cup chocolate chips and zigzag over the top. Sprinkle flaky sea salt if using.
Chill 30 minutes to firm, then lift out using parchment and cut into 16 bars. Store covered at room temperature up to 2 days or refrigerated up to 5 days.
Notes
For cleaner slices, warm a sharp knife under hot water and wipe between cuts. Bars freeze well for up to 2 months; thaw in the fridge overnight.
