Ingredients
  

  • 2 cups confectioners’ sugar
  • 2 tbsp molasses
  • 2 tbsp butter
  • ½ tsp ground ginger
  • boiling water (just enough to soften mixture, ~1–2 tbsp)

Instructions
 

Step 1: Prepare Sugar Mixture

  • Place 2 cups of confectioners’ sugar in a mixing bowl.

Step 2: Add Flavor Base

  • Add 2 tablespoons of molasses and ½ teaspoon of ground ginger.

Step 3: Soften with Boiling Water

  • Add just enough boiling water (about 1–2 tablespoons) to soften the sugar. Stir to blend.

Step 4: Combine with Butter

  • Add 2 tablespoons of softened butter to the sugar mixture. Beat until smooth and creamy.

Step 5: Adjust Consistency

  • If the frosting is too thick, add a few drops of boiling water to reach spreadable consistency.

Step 6: Use Immediately

  • Spread over cake or cupcakes while still soft. Frosting will set upon cooling.

Tips

  • Use fresh ground ginger for a sharper, more aromatic flavor.
  • Cook the syrup carefully to soft-ball stage to avoid grainy frosting.
  • Beat while warm for a smoother, glossier finish.
  • Add a pinch of cinnamon or cloves for extra warmth.
  • Drizzle warm over spice cake for a thinner glaze-style frosting.
  • Let cool slightly before spreading for a thicker texture.
  • Works especially well on gingerbread, spice cake, or molasses cake.
