In a bowl, add all dry ingredients and stir until combined.
Crack eggs and use a fork to incorporate them into the dry ingredients.
Next, add banana slices and incorporate them slowly with the above.
Add melted coconut oil (liquid) as well and incorporate slowly, forming a thick and creamy batter.
Pour batter into each mug, in equal quantities, leaving a bit of space at the top.
Decorate with cranberries on top of each mug. Optionally, you can use a teaspoon to mix extra cranberries into batter (while in the mugs).
Move into the oven and bake at 170 Celsius for 30-40 minutes, or until the batter turns solid. Do not over bake as these mug cakes will dry up pretty quickly.
Remove from the oven when done and set aside to cool down and do its thing. You can serve this mug cake hot or at room temperature.
DONE! Enjoy without guilt and share with others!
