Chocolate Cake in a Mug

A friend sent me this cake in a mug recipe. I think this is such a fun idea to cook with small children or grandchildren. Or it would be a fun treat to fix with the family for Family Home Evening.
5 MINUTE CHOCOLATE MUG CAKE
4 T. flour
4 T. sugar
2 T. cocoa
1 egg
3 T. milk
3 T. oil
3 T. chocolate chips (optional)
splash of vanilla extract
1 large coffee mug
Add dry ingredients to mug, and mix well. Add the egg and mix thoroughly. Put in the milk and oil and mix well. Add the chocolate chips (if using) and vanilla extract, and mix again.
Put your mug in the microwave and cook for 3 minutes at 1000 watts.
The cake will rise over the top of the mug, but don't be alarmed.
Allow to cool a little, and tip out onto a plate.

First mix the dry ingredients in the mug

Stir in the egg, and then add the rest of the wet ingredients

As it cooks, it rises over the top. Once it's done, it pulls away from the edge of the mug.
Tip out onto plate


I made this with the chocolate chips and noticed they mainly settled to the bottom of the mug. I'm not sure I'd add them next time.
I googled Mug Cake recipes and noticed most started with a ready made cake mix. I liked this one because I was able to use ingredients from scratch.
Also, I felt it would be even better if I had drizzled a frosting over the top. Below is my favorite Ganache frosting recipe that is very easy to do.
Ganache Frosting
20 oz. milk chocolate, chopped
1 1/2 C. heavy cream
Place the chocolate in a medium bowl. Heat the cream in a small saucepan over medium heat. Bring just to a boil, watching very carefully because if it boils for a few seconds, it will boil out of the pot. When cream has come to a boil, pour over the chopped chocolate and whisk until smooth. Allow the ganache to cool.
