What is a Shake Cake?

I saw this in a post...

Also how do you make a protein coffee?

Thanks ;)

 Have no idea what a Shake Cake is but here is my protein coffee recipe:

In large shaker bottle:

some ice cubes
coffee, room temp or from the fridge
load of heavy whipping cream
2 packets no sugar sweetner
couple pumps of sugar free carmel syrup from Starbucks
2 scoops of chocolate protein powder

Shake, shake, shake and enjoy!!!!

Sounds yummy :) 

I didn't know Starbucks make sf carmel syrup...thanks!

Here's a link I have with a recipe for the shake cake.

Don't know about shake cake, but I do know about Iced Hazelnut Coffee Shake-

In 16 oz blender bottle, combine:

6 oz whole milk

2 oz heavy cream

6 oz cold decaf hazelnut coffee

2 scoops unflavored whey protein isolate (or whey protein, whichever you use)

SF sweetener to taste

Ice

Enjoy!

Is there a way to replace the whole milk in that recipe?

 Yea, use half and half or all cream

Would you add some water though so it wasn't so thick? Maybe more coffee?

 I have a birthday cake protein that I want to make into a shake cake
