Extra milk or dark chocolate for melting and drizzling.
Instructions
Preheat oven to 350ºF. Line a - inch square pan with non-stick foil or parchment paper. Alternatively, you can use an 8-inch pan but the bake time might be a little longer.
In a microwave-safe mixing bowl, melt the butter. If using the 3 tablespoons of chocolate chips, add them to the melted butter and stir until melted. Stir in the cocoa and let the mixture cool. When cool, stir in the sugar, flour and salt and mix with a wooden spoon.
Crack in the eggs, one by one and beat with the spoon, then beat in the vanilla until the mixture is well-blended. Pour into the pan and bake for 20 minutes or until top appears set. Remove from the oven and let cool for about 10 minutes.
Warm peanut butter for 10 seconds in the microwave and spread it over the brownies. Sprinkle marshmallows, chocolate chips and peanuts over the peanut butter layer. Return the oven and bake for 3-4 minutes or just until marshmallows puff up. Let cool at room temperature or let cool slightly and throw in the freezer if you want to quick set.
If desired, melt some milk or dark chocolate in the microwave using 50% power. Drizzle melted chocolate over the rocky road topping. Let cool completely, then put in the refrigerator. When chilled, lift from pan and cut into 16 squares.
