Homemade Citrus Cake Glaze

ML
By Marie Lefebvre · Updated September 21, 2026

A light, silky glaze that takes any lemon or orange cake to the next level. Made with simple pantry staples, it has a gentle tang and a smooth pourable consistency — far lighter than cream cheese or condensed milk frostings. Ready in just 10 minutes.

🛒 Ingredients

8 servings

8
  • 1 cup (250 ml) whole milk
  • 2 tablespoons cornstarch
  • Juice of 2 lemons or 2 oranges (about ⅓ cup)
  • 1 teaspoon unsalted butter
  • Granulated sugar, to taste
  • Zest of 1 lemon or 1 orange, for decoration

Directions

  1. 1

    Whisk the cornstarch into the cold milk in a small saucepan until completely smooth with no lumps.

  2. 2

    Stir in the citrus juice, butter, and sugar to taste, starting with a small amount and adjusting as you go.

  3. 3

    Cook over medium heat, stirring constantly, until the mixture thickens to a pourable custard-like consistency.

  4. 4

    Remove from heat and let cool completely in a bowl — the glaze will thicken further as it cools.

  5. 5

    Blend the zest of one citrus fruit in a blender or chop it very finely with a knife.

  6. 6

    Unmold your cooled cake, pour the glaze generously over the top and let it drizzle down the sides.

  7. 7

    Decorate with the blended zest and curled strips of citrus peel. Serve immediately or refrigerate until ready.

💡 Chef's Tip

For a tropical twist, swap the milk for coconut milk and use lime juice — surprisingly delicious. The glaze keeps well in a sealed jar in the fridge for up to 3 days; just stir before using.
