Ingredients

Crust & topping:

  • 1 cup unsalted butter melted
  • 1 ½ cups light brown sugar packed
  • 2 teaspoons pure vanilla extract
  • 2 cups all purpose flour
  • 1 ¾ cups old fashioned rolled oats
  • 1 teaspoon baking soda
  • ¼ teaspoon salt

Fudge filling:

  • 12 oz bag semisweet chocolate chips
  • 14 oz can sweetened condensed milk
  • 2 tablespoons unsalted butter
  • 1 teaspoon pure vanilla extract

Instructions

Crust and topping:

  • Preheat oven to 350°F with a rack in the center of the oven. Line an 9x13 baking pan with foil or parchment and lightly spray with nonstick spray. Set aside.
  • In a large bowl, whisk the melted butter, brown sugar, and vanilla until well combined, at least one full minute.
  • In a separate bowl, combine the flour, oats, baking soda, and salt. Add the dry ingredients to the wet ingredients and stir to combine with a wooden spoon or rubber spatula.
  • Dump a little more than two-thirds of the mixture into the prepared pan and press into an even layer. You should have about 1-½ cups remaining, set it aside for the topping. Proceed with the fudge filling.

Fudge filling:

  • In a medium saucepan set over medium-low heat, combine chocolate chips, sweetened condensed milk, and butter. Cook, stirring frequently, until the chocolate chips are completely melted and the mixture is smooth and combined. Stir in the vanilla extract then immediately pour over the crust. Gently spread into an even layer.
  • Sprinkle the reserved topping over the fudge filling. Bake for for 18-20 minutes, until the top is golden brown. Place on a wire rack to cool completely.
