Preheat the oven: Preheat your oven to 375°F (190°C). Grease your donut pan.

Mix the dry ingredients: In a bowl, whisk together flour, sugar, baking powder, and salt.

Mix the wet ingredients: In another bowl, combine eggs, milk, melted butter, and vanilla extract. Mix until smooth.

Combine the mixtures: Add the wet ingredients to the dry ingredients and stir until just combined. Fold in chocolate chips.

Bake the donuts: Fill each donut mold halfway with batter. Bake for 12-15 minutes or until a toothpick comes out clean.

Prepare the glaze: In a microwave-safe bowl, heat heavy cream until hot. Pour over chocolate chips and stir until smooth.

Glaze the donuts: Dip the top of each donut into the chocolate glaze and let the excess drip off. Sprinkle chocolate shavings if desired.
Serve & Enjoy: Let the donuts cool slightly before serving!
