Description

This easy chocolate glaze is perfect for homemade donuts!


Ingredients

Scale
  • 1 cup powdered sugar (100 grams)
  • 1/4 cup unsweetened cocoa powder (25 grams)
  • pinch of kosher salt
  • 3 Tablespoons unsalted butter, melted (45 grams)
  • 1/2 teaspoon vanilla extract (2 grams)
  • 2 Tablespoons very hot water (30 grams - you may not need it all)


Instructions

  1. Whisk powdered sugar and cocoa powder together with a pinch of kosher salt in a medium mixing bowl.
  2. Whisk melted butter and vanilla extract into powdered sugar mixture. The mixture will be clumpy - that's ok! 
  3. Add hot water a little bit at a time, whisking well between each addition, until you have a smooth, shiny glaze. You may not need all the hot water! 
  4. Dip the top of your prepared, cooled donuts into the glaze and let any excess drain off. Transfer to a wire cooling rack (you may want to put a towel or plate under the wire rack to catch any drips of frosting). Top donuts with sprinkles while glaze is still wet. Let the glaze set for at least half an hour to achieve a shiny finish! 

Notes

Additions and Substitutions. Omit the vanilla extract if you don't have any (it adds a bit of depth, but this recipe still works fine without it!) Use melted coconut oil instead of butter for a dairy-free/vegan version (the coconut oil will act similarly to butter and help the glaze firm up as it dries). Use milk or cream instead of hot water if you want the frosting to stay soft instead of firming up.

How hot should my water be? We use an electric kettle to heat water to near-boiling (just like making tea!) You can also heat water in the microwave or use tap water on its hottest setting. Hot water is important because it keeps the butter warm while you frost the donuts (as the butter starts to cool, the frosting sets and gets harder to work with). The heat also helps "bloom" the cocoa, which brings out more chocolate flavor.

If the icing is too thin, let it cool on the counter for a few minutes, then stir and try dipping the donuts again. If frosting gets too thick, add an extra splash of hot water or microwave it for a few seconds to loosen it up. This glaze is fairly forgiving: If you accidentally add too much water, add a few extra spoonfuls of powdered sugar and/or cocoa powder to get it back to the right consistency.

This glaze can take some practice. For best results, the glaze should be a pourable - but not watery - consistency when you dip the donuts. You want it to resemble a thick syrup. If the glaze soaks into the donut or runs right off and leaves a too-thin layer, let it sit for 5-10 minutes, then stir and dip again (as it sits, the glaze will thicken a bit). If the glaze thickens too quickly, add a splash of hot water or microwave it for a few seconds to loosen it back up.

Quantities. This recipe makes enough glaze for 12-16 baked donuts (about 3.25" in diameter) or 8-10 classic yeast donuts (about 4.5" in diameter). Double or triple this recipe if you'd like more icing.
