Tips to make Banana Protein Mug Cake

This fudgy flourless banana protein mug cake really is a simple one and made in a mug or ramekin, but make sure you do all of this stuff to get is perfect.

Grease the ramekin! You want the banana pudding mug cake to come off easily.
Use an oven-safe mug if you need.

Use completely ripe/overripe banana since it is more sweet, and will also mash better.

Don’t over-mix the batter!
Make sure you gently stir the wet and dry to combine them.
If you over-mix it, protein powder will make your protein mug cake tough, dense and gummy.

Taste the batter and see if you need some extra sweetener. I’d recommend using stevia powder to maintain the consistency of the batter.

Don’t overbake the mug cake. The top will should be just cooked. It might look soft, but will harden when it cools a bit.
It will continue to cook when out, and you want the proper fudgy center.
