Tips to make Fudgy Pecan Protein Powder Mug Cake

This fudgy flourless pecan mug cake with protein powderreally 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 pecan pie mug cake to come off easily.
Use an oven-safe mug if you need.

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.

Use cold, grated butter so it mixes well with the rest of the healthy pecan streusel topping ingredients.

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.
