In a small saucepan, melt the butter over low heat.
Whisk in the unflavored whey protein isolate and mix it until this thick and creamy.
Continue using the whisk to mix in the water and heavy whipping cream. Mix until it's well incorporated.
Turn off the heat and set it aside. It will thicken more as it cools.
Start to prep the chicken.
Add the chicken to a large ziplock bag.
Add all the seasonings to the bag and shake it until the seasonings have completely coated the chicken pieces.
In a small bowl, combine the pork panko and the remaining seasonings.
Remove each piece of chicken from the ziplock bag and dip it in the somewhat cooled keto buttermilk mixture.
Now dip that piece of chicken into the pork panko.
Repeat the above sets until all the chicken has been prepped.
