Preheat the oven to 350°F and lightly grease a regular-sized donut pan. Set aside.
In a large bowl whisk together the vanilla, milk, melted butter, and egg.
2 eggs, 1/2 cup milk, 3 tbsp butter, 1 tbsp vanilla
Add in flour, brown sugar, salt, and baking powder. Switch over to a spatula and gently fold in until there are no dry streaks. Make sure not to over-mix!
1 1/4 cups all-purpose flour, 1/2 cup dark brown sugar, 1/4 tsp salt, 1 tsp baking powder
Distribute the batter evenly along the pan. A piping bag works best for this but if you don't have one use a spoon.
Bake for 10-11 minutes or until the donut springs back when you lightly press it. Allow to cool while you make the glaze.
Using a double boiler method add the heavy cream and stir until warm. Then add in the chocolate chips and mix until it turns into a thick ganache. Let the ganache cool down for a few minutes before dipping.
1/2 cup heavy cream, 1 cup semi-sweet chocolate chips
Once the donuts are cool enough to touch, dip them in the chocolate ganache. Placing them on the cooling rack and allow the ganache to set here; repeat with all donuts. If desired, add sprinkles while the ganache is still setting!
These donuts are best eaten the day they're made. I don't recommend making them ahead of time. Enjoy!
