Single Serving Marshmallow Vanilla Protein Cake

I haven't made a mug cake in quite some time and I was craving one so I decided to throw this together.  I love using casein for my base protein in my baked goods because it results in a fudger texture which I prefer over a drier, cakey batter.  I added a little bit of everything that I had in the cabinet to create the s'mores themed cake!

Single Serving Marshmallow Vanilla Protein Cake

1. Spray a ramekin with healthy cooking spray
2. Combine all ingredients (except the marshmallows) until fully incorporated
3. Transfer half of the batter to the ramekin then add the marshmallows and then the remaining batter
4. Microwave for 1 to 1 1/2 minutes
5. Remove from the ramekin and top with desired toppings ( I used chocolate sauce, multi-grain cheerios, sprinkles, and mini marshmallows)
