Protein Packed Sweet Potato and Protein Slab

Protein Packed Sweet Potato and Protein Slab

Although this is called it a "slab"  it isn't heavy. With the sweet spice of Christmas this is a lovely combination of the texture of a brownie but with all of the flavour of Christmas.  

With Boditronics sweet spice ISO Whey 100% Whey Isolate protein, sweet potato and pecans as its main ingredients this also has a beautiful crunch. once you've grated the sweet potato you mix the ingredients together so its also fool proof (after a few attempts at our end!)  

The hardest part is waiting for it to cool before you decorate it.. but this is off course optional

You will need:

  • Mixing Bowl
  • Cheese grate or food processor with grating attachment for grating sweet potato
