Preheat oven to 350°F. Line your mini muffin tin with cupcake liners. Please note, mini muffin tins come in a few different sizes. My cooking directions were based on the usage of the Wilton mini muffin pan. If your mini muffin molds are slightly bigger or smaller, you will have to adjust the cooking time accordingly.
In a large mixing bowl, add the first four ingredients. Mix with a whisk until a smooth, uniform batter forms.
Fill cupcake liners 2/3 full with batter. Sprinkle about 1/2 tsp of mini chocolate chips on top of each muffin. Note, if you choose to omit the chocolate chips, the batter will not be sweet enough and you'll likely need to add more sugar to the original batter.
Bake for about 10-12 minutes (I did the full 12 for mine), until muffin tops look completely cooked and knife inserted comes out clean.
Notes
If you don't have mini chocolate chips you can chop up a chocolate bar or chop up regular chocolate chips instead.
