1/2 cup butter
14 ounces sweetened condensed milk
1 cup packed dark brown sugar
2 tablespoons light corn syrup
1 cup white baking chips
1/2 teaspoon coarse sea salt
Line 8” square baking pan with foil; coat with cooking spray. Melt butter in medium saucepan over medium-low heat. Stir in sweetened condensed milk, brown sugar and corn syrup. Cook over medium heat until sugar is melted and mixture comes to a simmer, stirring frequently. Reduce heat to low. Simmer 10 minutes, stirring constantly, until mixture begins to thicken (you will begin to slightly see the bottom of the pan while stirring).
Remove from heat; let stand 30 seconds or until bubbles stop. Stir in baking chips; let stand 2 minutes. Stir until melted and smooth. Pour and spread into baking pan; sprinkle with salt. Refrigerate 2 hours or until firm.
