Spiced Rum Glaze

A robust, pourable icing made by whisking together dark spiced rum, powdered sugar, and a touch of melted butter until the mixture reaches the consistency of heavy cream. It sets firmly as it cools, creating a translucent, amber-hued coating that provides a sharp, aromatic finish to dense cakes like bundt or pound cakes.

Before you start

Watch the sugar-to-liquid ratio carefully.

This glaze relies on the precise balance between the sugar and the rum to ensure it doesn't soak entirely into the cake or slide off the sides.

  • measuring spoons
Ingredients

What goes in.

  • 1.5 cupsconfectioners' sugar, sifted
  • 3 tbspdark spiced rum
  • 1 tbspunsalted butter, melted
  • pinchfine sea salt
The key technique

Checking the viscosity

Lift your whisk and let the glaze drip back into the bowl; it should flow in a slow, continuous ribbon that briefly sits on the surface before disappearing back into the mixture.

Step by step

The method.

  1. Sift the sugar

    Place the confectioners' sugar into your bowl through a fine-mesh sieve to remove any lumps, which otherwise create pockets of dry sugar in the finished glaze.

  2. Incorporate the butter

    Pour the melted butter into the sugar and whisk until the mixture resembles wet sand.

  3. Add the rum

    Pour in the spiced rum one tablespoon at a time, whisking vigorously after each addition until the glaze is smooth and glossy.

  4. Adjust

    If the glaze is too thin to coat the back of a spoon, add a teaspoon more sugar. If too thick, add a few drops of rum.

  5. Apply

    Drizzle immediately over a completely cooled cake, working from the center outward so the glaze drips evenly down the sides.

Variations

Other turns to take.

Citrus Spiced

Replace one tablespoon of rum with freshly squeezed orange juice for a brighter, lighter finish.

Extra Warm

Whisk in a quarter-teaspoon of ground cinnamon or freshly grated nutmeg to amplify the spice profile.

Tips & troubleshooting

When it doesn't go to plan.

Tip

Always glaze on a wire rack set over a rimmed baking sheet to catch the runoff.

Tip

If the glaze starts to thicken too much while you work, whisk in a few drops of warm water.

Tip

Do not attempt to glaze a warm cake, or the sugar will melt and absorb completely rather than forming a glaze.

Questions

The ones that keep coming up.

Can I use light rum?

You can, but you will lose the depth of molasses and vanilla notes that define a spiced rum glaze. You may want to add a dash of vanilla extract if using light rum.

How long does it take to set?

It generally becomes firm to the touch within 30 minutes at room temperature.
