Simple syrup is the easiest way to add moisture and flavor to cakes, and the same equal-parts mixture is useful for iced drinks, coffee, tea, and cocktails. The syrup stays thin so it can soak evenly into a cake’s crumb.
Keep it plain or flavor the cooled syrup with vanilla, citrus zest, herbs, spices, or a small splash of liqueur. Brush or drizzle it over cooled cake layers before adding filling or frosting.

Instructions
- Combine the water and sugar in a medium saucepan.
- Set over medium heat and bring to a boil, stirring until the sugar dissolves completely.
- Let the syrup bubble gently for 2 to 3 minutes, then remove it from the heat.
- Pour into a heatproof container and cool to room temperature. The finished syrup should remain thin and pourable.
- If using vanilla, liqueur, citrus, herbs, or another flavoring, stir it into the cooled syrup a little at a time and taste as you go. Cover tightly and refrigerate.
Flavor Ideas and Storage
- For berry or cherry cakes, add kirsch or another berry liqueur.
- For orange cakes, try Grand Marnier; for citrus cakes use limoncello, Campari, or Aperol.
- Dark rum pairs well with vanilla cakes and warm spices.
- Herbs and whole spices may be infused while the syrup cooks; strain them out after cooling.
- Store tightly covered in the refrigerator for up to 1 month for best quality.
