1 ½ sticks unsalted butter, melted
1 ¼ cup packed light brown sugar
2 large eggs
¼ cup Michter's US1 Small Batch Bourbon
1 teaspoon coarse salt
1 ¾ cups all-purpose flour
1 teaspoon baking powder
1 cup milk chocolate chips
½ cup butterscotch chips
¾ cup toffee bits
Preheat oven to 350 degrees Fahrenheit. Butter and line a 9-inch square baking pan with parchment paper, leaving a 2-inch overhang. Set aside. In a large bowl, whisk together melted butter and brown sugar. Add eggs, one at a time, whisking until combined. Add bourbon and salt. Gently fold in flour and baking powder, scraping down sides of bowl as needed. Add ½ cup milk chocolate chips, ¼ cup butterscotch chips and ½ cup toffee bits. Mix until combined. Pour batter into pan and top with remaining chocolate, butterscotch and toffee bits. Bake until golden and a toothpick inserted comes out clean, about 30-35 minutes. Cool completely and remove to cutting board and cut into squares.
