First, spray a mug or ramekin with non-stick spray.
Add flour, sugar, baking powder, cinnamon & nutmeg to a bowl.
Mix this up really well!
Add oil, milk, and vanilla to the flour mixture.
Mix it really well. There should be no lumps!
Fold in 2 tsp of the shredded carrot and chopped walnuts.
Microwave for 60-90 seconds. Every microwave is different so take a toothpick and insert it- when it comes out clean it’s done!
Now, to make the frosting pop your cream cheese into the microwave for just 10 seconds to soften.
Then mix with powdered sugar and place on top of your mug cake.
Top with a bit of extra shredded carrot and chopped walnuts and enjoy! Make sure these walnut pieces aren’t huge!
