You pancake recipe looks like a great one to use when working on gaining some mass. I haven't tried using my protein powder (other than some collagen powder) in pancakes yet but I do make a chocolate pudding with a scoop of beef protein powder.

Here's the recipe for any pudding lovers:

5 cups water
1 teaspoon salt
1 teaspoon vanilla
1 scoop (about ~30 grams for me) chocolate or vanilla protein powder (I've used PurePaleo beef protein from Designs for Health)
3 heaping tablespoons cocoa
1/2 cup honey, sugar or xylitol
4 eggs
6 tablespoons butter (I use Kerrygold from Ireland)
1 cup of small pearl tapioca (pre-soak in water for an hour or more first)

I combine all this in a pot and whisk over heat until the tapioca swells and the pudding thickens. It's important to whisk the eggs into the other ingredients before the heat rises or you will have clumps of cooked egg white throughout.

I use water and butter instead of milk because of a dairy protein sensitivity. The butter is almost all fat and is low in dairy proteins so it works better than using milk.

You can also make this recipe with pre-cooked rice instead of tapioca. In that case it's a good idea to mix in 2-3 tablespoons of potato, tapioca or corn starch so that it will still thicken nicely.

This is delicious served over frozen blueberries. More of a mass gain recipe than a cutting recipe for sure :)
