Ingredients List

  • Bakers Chocolate Squares
  • Butter
  • Powdered Sugar
  • Salt
  • Milk
  • Rum

Bakers Chocolate: Any brand will do, I’ve tried them all and they’ve all worked wonderfully in this recipe. Just make sure to use unsweetened bakers chocolate.

Milk: I highly recommend using whole fat milk for your frosting. That added butterfat content is an important part of the final texture. But, you can go with 2% in a pinch, but I would not go with a lower fat content than that.

Rum: So, I’m not a big rum drinker so I will leave the recommendations on what to get to others. But if you do enjoy rum or making drinks with it, just go with your usual style for your frosting.

Simple Step by Step Recipe Instructions

So, this recipe is not difficult at all. There are no hard to follow steps, so you will be done making it in no time.

For that reason, I recommend starting your frosting just when your cake or cupcakes are about finished cooling.

You can also make your chocolate rum frosting ahead of time and store it in the refrigerator in an airtight container. Either way is fine!

Note: When melting your chocolate and butter, place them both in a microwave safe bowl. Heat on high for 20 seconds and then stir. Continue to heat in 20 second increments, stirring between, until mixture is melted. Use caution not to overheat and burn your chocolate.

Step 1: Add melted chocolate and butter mixture to mixing bowl along with your powdered sugar and salt

Step 2: Stir until well blended

Step 3: Add you milk and rum one tablespoon at a time, stirring between each tablespoon until mixture is smooth and creamy

Note: For a thinner frosting, stir in a tablespoon at a time of either rum or milk until desired thickness is achieved.

Step 4: Use immediately or store in the refrigerator
