Mix together mascarpone/cream cheese and peanut butter until smooth.
Add in chocolate whey powder and combine until completely mixed, and a dough forms.
I used my hands here, and kneaded it until everything was completely mixed in.
I seriously use exam gloves to keep my hands clean!
Press dough mixture into a silicon pullman loaf pan or a regular pullman loaf pan that has been lined with parchment/wax paper and chill for 10-15 minutes.
You don't want it hard, just a little chilled.
Turn out loaf onto a cutting board and slice into 6 equal pieces.
Wrap in wax paper and store in the fridge!
