I had plans for cookies with the single peach I had in my pantry, but then this mug cake idea came up. My fiancé really loved the upside down blood orange protein mug cake I’d made a short while ago, and he wanted something like it.

Way to the man’s heart is through his stomach? Haha. Ended up going for this mini peach protein cake and it turned out lovely!

Tips to make Peach Mug Cake with Protein Powder

This flourless protein powder peach 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 peach 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 healthy 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 peach mug cake. The top will should be cooked. It might look slightly soft, but will harden when it cools a bit.
