Gluten-free Single Serve Chocolate Cake

This is an adaptation of a 5 min microwave cake someone showed me long ago, and I finally decided to make a second attempt at a healthier and gluten-free version (my first attempt turned out horrid), and it turned out surprisingly GOOD!  I'm not a pro at adapting recipes and actually have them turn out good in the end.
This one takes a little longer than 5 minutes to do though.  Unless you have superman's speedy powers.

It really doesn't look impressive as far as cakes go, but the taste makes up for it.
And this version actually turned out more moist and gooey-fudgy than the original, so it's delicious!

2 tbs coconut flour
2 tbs gluten-free flour mix
3 tbs cocoa powder
1/2 tsp baking powder
egg replacer equivalent to 2 eggs
3 tbs greek yoghurt
3 tbs coconut oil (liquid)
3 tbs agave nectar

• combine flours, cocoa powder & baking powder in a coffee mug & mix with a fork
• add egg replacer & greek yoghurt and mix well to combine fully
• add coconut oil & mix
• add agave and mix well to combine, and make sure there's no dry flour in the bottom of the mug
• microwave for 3 mins
