Ingredients

  • 1 cup powdered sugar (ensure vegan-friendly, some brands use bone char)
  • 2 tablespoons coconut milk (full fat for creaminess)
  • 1 tablespoon vegan butter (softened)
  • 1 teaspoon vanilla extract
  • ¼ teaspoon ground cinnamon (optional, for extra warmth)
  • Pinch of salt

Equipment

  • Mixing bowl
  • Whisk or hand mixer
  • Measuring cups and spoons
  • Spatula
  • Small saucepan (optional, if you want to melt the vegan butter)

Instructions

  1. Prepare your ingredients. Make sure the vegan butter is softened to room temperature. This helps it blend smoothly with the other ingredients.
  2. Mix powdered sugar and cinnamon. In a mixing bowl, sift together the powdered sugar and ground cinnamon to prevent lumps and evenly distribute the cinnamon flavor.
  3. Add wet ingredients. Pour in the coconut milk, softened vegan butter, vanilla extract, and a pinch of salt.
  4. Whisk until smooth. Using a whisk or hand mixer, blend all the ingredients together until the icing is creamy and lump-free. If the icing is too thick, add more coconut milk, one teaspoon at a time, until you reach your desired consistency.
  5. Taste and adjust. Give your icing a quick taste. If you want it sweeter, add a little more powdered sugar. If you prefer a stronger cinnamon flavor, sprinkle in a bit more cinnamon and mix again.
  6. Drizzle or spread. Use a spoon or spatula to generously coat your freshly baked cinnamon buns. The icing will set slightly but remain soft and luscious.
  7. Serve immediately or store. For the best texture, serve right away. Leftover icing can be refrigerated in an airtight container for up to 3 days. Stir well before using again.

Tips & Variations

Pro tip: If you want a silkier icing, warm the coconut milk slightly before mixing. This helps the vegan butter melt better and creates a smoother texture.

Looking to switch things up? Here are some ideas:

  • Maple Cinnamon Icing: Replace the vanilla extract with 1 tablespoon of pure maple syrup for a rich, autumnal twist.
  • Lemon Glaze: Add 1 teaspoon of freshly squeezed lemon juice and a teaspoon of lemon zest for a bright contrast to the cinnamon.
  • Nutty Flavor: Stir in 1 tablespoon of almond or cashew butter for extra creaminess and a nutty undertone.
  • Spiced Up: Add a pinch of nutmeg or ground cloves alongside the cinnamon for a cozy spice blend.
  • Sugar-Free Option: Use powdered erythritol or monk fruit sweetener as a substitute for powdered sugar.
