Frosted Butter Rum Brickle Bites

The rum, real butter and toffee bits made these cookies my husband’s new favorite. If you’d like them less sweet, skip the frosting and sprinkle the cookies with confectioners’ sugar while still warm. —Cindy Nerat, Menominee, Michigan
  • Total Time
    Prep: 35 min. Bake: 10 min./batch + cooling
  • Makes
    about 4 dozen


  • 1 cup butter, softened
  • 3/4 cup confectioners' sugar
  • 2 teaspoons rum extract
  • 1/2 teaspoon salt
  • 2 cups all-purpose flour
  • 1 package (8 ounces) brickle toffee bits
  • ICING:
  • 1/3 cup butter, cubed
  • 2 cups confectioners' sugar
  • 1/2 teaspoon rum extract
  • 2 to 3 tablespoons 2% milk


  • Preheat oven to 375°. Beat first 4 ingredients until blended. Beat in flour. Stir in toffee bits. Shape dough into 1-in. balls; place 2 in. apart on parchment-lined baking sheets.
  • Bake until edges are light brown and toffee bits begin to melt, 8-10 minutes. Cool on pans 5 minutes. Remove to wire racks to cool completely.
  • In a small heavy saucepan, melt butter over medium heat. Heat until golden brown, about 5 minutes, stirring constantly. Remove from heat; stir in confectioners' sugar, rum extract and enough milk to reach desired consistency. Spread over cookies.

Test Kitchen tips
  • You'll know these cookies are done when the toffee bits around the edges just start to melt and the edges of the cookies are lightly browned.
  • This icing is thick and buttery with a hint of toasted flavor. It would also enhance pecan shortbreads or pumpkin cookies.

      I wanted to love these cookies but they are just far too sweet. Even my 8 yr old son said they were too sweet for his liking (even without the icing). So, I love the idea and ingredients but I recommend tweaking the recipe to be less sweet.

      I can't believe there are only 2 reviews for these cookies. They are amazing! Along with several other cookies I make for Christmas, I make them ahead of time and freeze them. They are the first cookie I reach for when I put out a platter.

      These cookies are easy to bake and tasty. The rum extract is what makes the cookie. However, we felt the frosting was not needed and made the cookie too sweet.
