Best Chocolate Mug Cake- No Egg Needed-Dairy Free Option

I love this mug cake! I've made it so many times I have it memorized. I first made it when my son was a newborn and I wanted something easy at the end of the day. Something just for me, because we all know newborns take a lot out of us. So... this is it! The best cake (to me). If you want it dairy free you can use almond milk and exclude or substitute the chocolate chips.
I found the original recipe somewhere online. Can't remember where. Sorry!
Original Chocolate Mug Cake
3 Tb flour
3 Tb powdered sugar
2 Tb cocoa powder
1/4 tsp baking soda
dash salt
3 Tb canola/veg oil
3 Tb milk
1/4 tsp vanilla extract
1 tsp chocolate chips

Erin's Chocolate Mug Cake
3 Tb flour
3 Tb powdered sugar
1 1/2 Tb cocoa powder
1/4 tsp baking soda
dash salt
1 Tb applesauce
2 Tb canola oil
3 Tb almond milk (Sometimes I substitute 1-2 Tb with leftover coffee)
1/4 tsp vanilla extract
2 tsp chocolate chips (Sometimes a dollop of peanut butter too!)

Mix everything except for chocolate chips in a mug. Sprinkle chocolate chips in the center. Microwave 1:05. (You might have to vary it, but DO NOT OVERBAKE. You want to see some gooeyness) I usually race the microwave and try to clean everything up while the cake is cooking. Top with ice cream, leftover frosting, caramel/chocolate sauce.... and enjoy!
