Just when we thought rich and chewy blondies couldn't get any better, our home economists dreamed up this luscious sundae version. Topped with creamy vanilla ice cream and a sweet butterscotch sauce, this dessert takes decadence to the next level. —Taste of Home Test Kitchen


  • 1 large egg
  • 1 cup packed brown sugar
  • 1/2 cup butter, melted
  • 1 teaspoon vanilla extract
  • 1-1/4 cups all-purpose flour
  • 1/8 teaspoon salt
  • 1 cup butterscotch chips
  • 1/2 cup butter, cubed
  • 1 cup packed brown sugar
  • 1 cup heavy whipping cream
  • 1/2 teaspoon salt
  • 1-1/2 teaspoons vanilla extract
  • 4-1/2 cups vanilla ice cream


  1. In a large bowl, beat the egg, brown sugar, butter and vanilla. Combine flour and salt; gradually beat into egg mixture. Fold in chips.
  2. Transfer to a greased 8-in. square baking dish. Bake at 350° for 20-25 minutes or until a toothpick inserted in the center comes out with moist crumbs (do not overbake). Cool on a wire rack.
  3. For sauce, in a large saucepan, melt butter. Stir in the brown sugar, cream and salt. Bring to a boil; cook and stir for 5 minutes or until slightly thickened. Remove from the heat. Stir in vanilla. Cut brownies into squares; serve with ice cream and sauce.
