Line a large baking tray or 8 x 8 baking dish with baking paper and set aside.

In a large mixing bowl, combine your flour, protein powder, cocoa powder, salt and sweetener and set aside.
In a microwave melt peanut butter with honey.

Mix with dry ingredients until incorporated.

Using a tablespoon, add milk until a very thick batter is formed.

Transfer batter to lined baking tray and press firmly in place and place inside the fridge.

While chilling, start by making the frosting. Mix the first 3 ingredients then using a tablespoon, add milk until a thick and spreadable frosting is formed.

Top the bars with frosting and allow to freeze (the way I like it) or chill in the fridge.

Cut into bars.
