Mint Chocolate Brownies (York Peppermint Patties)

(Makes 16~Prep Time: 10 minutes~Total Time: 3 hours)

8 Tbsp. (1 stick) unsalted butter, plus more for pan
8 oz. semisweet or bittersweet chocolate, chopped
1 cup sugar
3/4 tsp. salt
3 large eggs
1/2 cup all-purpose flour (spooned and leveled)
1/4 cup unsweetened cocoa powder
25 small (1 1/2 inch) peppermint patties

1) Preheat oven to 350 degrees. Line an 8-inch square baking pan with aluminum foil, leaving an overhang on all sides; butter foil. Set aside.
2) Place chocolate and butter in medium heatproof bowl set over (not in) a saucepan of gently simmering water. Stir occasionally just until melted, 4 to 5 minutes.
3) Remove from heat. Whisk in sugar and salt until smooth; whisk in eggs. Gently whisk in flour and cocoa powder just until smooth (do not overmix).
4) Spread 1/3 of batter in prepared pan. Arrange peppermint patties on batter in a single layer, leaving a narrow border on all sides. Top with remaining batter, and smooth surface. Bake until a toothpick inserted in center comes out with moist crumbs attached, 45-55 minutes. (mine only needed about 35-40 minutes)
5) Cool completely in pan. Use foil to lift from pan; peel off foil and discard. Cut into 16 squares (4 rows by 4 rows).
