Whisk together all of the ingredients for the mug cake in a large mug until the batter is completely smooth.
Microwave on high for 1.5 to 2 minutes, until mug cake has risen and is cooked through. Insert a digital thermometer into the center of the cake. Ideally, the internal temperature should be between 190 and 205 degrees Fahrenheit in the middle.
Garnish with a drizzle of coconut milk, chopped pecans, and white chocolate chips. Allow cake to cool for a few minutes before diving in
Notes
*Start with one teaspoon of matcha powder if you're new to it. The flavor can be a bit bold for newbies!
