01 -
Preheat oven to 350°F (175°C). Lightly butter or spray a donut baking pan with non-stick cooking spray.
02 -
In a medium to large bowl, whisk together the flour, sugar, cocoa, baking soda, and salt until well combined.
03 -
In a smaller, separate bowl, stir together the milk, oil, vinegar, and vanilla extract.
04 -
Pour the wet ingredients into the bowl with the dry ingredients. Stir until no lumps remain and batter is smooth.
05 -
Spoon the batter into the prepared donut pan, filling each cavity about ¾ full.
06 -
Bake in the preheated oven for 14-15 minutes, or until a toothpick inserted into a donut comes out clean.
07 -
Allow donuts to cool in the pan for 5 minutes before turning out onto a wire cooling rack to cool completely.
08 -
In a medium pot over medium heat, melt the butter. Stir in the cream or milk, corn syrup, and vanilla extract.
09 -
Add the chocolate chips to the pot, turning the heat down slightly if needed. Continue to cook and stir until the chocolate chips are completely melted and the mixture is smooth.
10 -
Remove the pot from heat and whisk in the powdered sugar. For a lump-free glaze, you may want to sift the powdered sugar before adding it.
11 -
Dip the top of each cooled donut into the still-warm glaze, allowing excess to drip off. Place back on the cooling rack.
12 -
If using sprinkles or other toppings, add them immediately after glazing each donut, before the glaze sets.
