Ingredients: 

3/4 cup unsalted butter (i.e 1.5 sticks; you will be melting this)

1 1/2 cups granulated sugar

1/2 cup light brown sugar

3 large eggs + 1 egg yolk

1 tablespoon vanilla extract

1 teaspoon salt

1/4 teaspoon baking soda

2 tablespoons cornstarch

1 1/2 cups Hershey's cocoa powder (100% cacao natural unsweetened)

1 cup Flourish flour

1/4 cup vegetable oil

easy chocolate ganache (see notes section below for a firmer, traditional ganache using heavy cream)

1 1/2 cups semi-sweet chocolate chips (i.e. 12 ounce bag)

6 tablespoons unsalted butter chopped into small cubes

1/2 cup whole milk (you can also use 2% or 1% but the ganache will be less firm so you will need to refrigerate and/or freeze brownies so frosting sets; see notes below)

Toppings - Sprinkles
