Ingredients

For the filling:
  • 1 1/4 cups (213 grams) semisweet chocolate chips
  • 1/3 cup (104 grams) sweetened condensed milk
  • 1 tablespoon (14 grams) unsalted butter
For the blondies:
  • 1 stick (113 grams) unsalted butter, melted
  • 1 cup (200 grams) light brown sugar
  • 1 large egg
  • 1 teaspoon vanilla extract
  • 1/8 teaspoon fine salt
  • 1 cup (127 grams) all-purpose flour

    Cup of Yum

Make the Filling:
    Cup of Yum
  1. In a small saucepan set over low heat, combine the chocolate chips, condensed milk, and 1 tablespoon of butter. Heat, stirring often, until melted and smooth. Set aside to cool.
Make the Blondies:
  1. In a large bowl, stir together the melted butter and brown sugar. Stir in the egg and vanilla until smooth. Add in the salt and flour and stir until just combined. The mixture will be thick.
Assemble:
  1. Spread half of the blondie batter into the bottom of the prepared pan. Scoop and flatten the fudge filling evenly over the dough. It doesn’t have to be perfect. Spread the remaining blondie batter over the fudge evenly to cover completely.
  2. Bake for 25 minutes, or until lightly golden on the outside but still fudgy and moist on the inside. It’s better to under-bake than over-bake here! Let cool completely before cutting.
