Add dry ingredients to a microwave safe mug or ramekin. Whisk.
Add soy milk and vanilla extract. Mix.
Add coconut oil. Mix.
Add chocolate chips. Fold into batter.
Microwave at 30 second intervals. I microwaved mine at 50 seconds, but your microwave may differ.
Notes
If you want to have some ready to go for later, pour the batter into single serving silicone molds and place in the freezer.Then scoop out the individual portion into a microwave safe mug and cook as normal.
