Ingredients

  • 16 tablespoons ground coffee
  • 40 ounces water
  • 5 teaspoons LorAnn butter pecan flavoring
  • 1 14-ounce can sweetened condensed milk
  • ice
  • 1½ tablespoons half and half

Instructions

Coffee Preparation

  • It is best to make the coffee a day in advance so it is cold for making the drink.
  • Brew ground coffee with water as you normally would. You will be using 1½ times more coffee than you normally do. Dunkin does it this way so when you add ice it does not water the coffee down.
  • Allow the coffee to cool to room temperature.
  • Store it in an airtight container in the refrigerator.

Butter Pecan Swirl Preparation

  • Place butter pecan flavoring and sweetened condensed milk in a small bowl. Stir to combine.
  • Store the butter pecan swirl in an airtight container like a canning jar or a squeeze bottle.

Butter Pecan Iced Coffee Preparation

  • Fill a 16-ounce glass ¾ full of ice.
  • Add half and half.
  • Add 1½ tablespoons of butter pecan swirl.
  • Fill the glass with cold coffee.
  • Use a bar spoon to mix the half and half and butter pecan swirl into the coffee.

What Can You Serve With Butter Pecan Iced Coffee

Serve the Butter Pecan Iced Coffee in a glass with plenty of ice. There is no need for any garnishes. But if you want to be decadent, top it with whipped cream and a caramel drizzle.

Since this intensely flavored drink, it can easily overpower anything served with it. Therefore, if you insist on snacking while drinking, try something pecan-flavored, such as Pecan Pie Brownies or these gorgeous Spiced Pecans.

Storage Instructions

Storing the Syrup

The homemade butter pecan syrup should be stored in an airtight container in your refrigerator. When properly stored, it will remain fresh for up to two weeks.

For more extended storage, portion the syrup into an ice cube tray, place in a freezer bag, and freeze for up to three months. Thaw cubes in the refrigerator before using.

Making Ahead

Prepare a larger batch of the butter pecan syrup and store it in the refrigerator for quick assembly of your morning coffee. You can also pre-make cold brew coffee to have on hand for an even faster preparation.
