Step 1: Preheat the oven
- Preheat your oven to 350°F (175°C). Lightly grease a donut pan with nonstick spray or butter.
Step 2: Mix the dry ingredients
- In a large bowl, whisk together the flour, sugar, baking powder, and salt.
Step 3: Mix the wet ingredients
- In a medium bowl, whisk together the milk, melted butter, eggs, and vanilla extract.
Step 4: Combine the mixtures
- Gradually add the wet ingredients to the dry ingredients, mixing until just combined (do not overmix). Gently fold in the mini chocolate chips.
Step 5: Fill the donut pan
- Spoon or pipe the batter into the prepared donut pan, filling each cavity about 2/3 full.
Step 6: Bake the donuts
- Bake in the preheated oven for 10-12 minutes, or until the tops spring back when lightly touched, and a toothpick inserted into the center comes out clean.
- Allow the donuts to cool in the pan for 5 minutes, then transfer to a wire rack to cool completely.
Step 7: Prepare the glaze (optional)
- In a small bowl, whisk together the powdered sugar, milk, and vanilla extract until smooth. Adjust the consistency by adding more milk (for a thinner glaze) or more powdered sugar (for a thicker glaze).
Step 8: Glaze and garnish
- Dip the cooled donuts into the glaze, allowing any excess to drip off. Sprinkle with additional mini chocolate chips if desired. Let the glaze set for 10-15 minutes before serving.
