No Added Sugar High Protein Banana Cake with Vanilla Cinnamon Probiotic Icing

Hi everyone,

I seem to have been getting more creative in my kitchen over the last couple of months, as I continue to discover the delicate art to mixing a range of high protein and high fibre grain replacements into my recipes.

In all my recipes I stick with using grain alternatives that are:

  • Low glycemic load
  • High in protein and/or
  • High in dietary fibre

I do this to ensure that the final baked good is truly nutrient dense, and continues to align with all my nutritional philosophies.

Some of my new favourites are Lupin Flakes and Black Bean Powder, alongside natural protein powders that are enhanced with either reds and greens powders for an extra anti-oxidant kick, or digestive enzymes to assist with the breakdown in our bodies.

I also make sure that my recipes fit within as many of the following criteria (if not all):

  • No added sugar
  • Probiotic enhanced
  • Prebiotic enhanced
  • Antioxidant packed
  • High protein
  • High fibre
  • Nourishing fat and fat soluble vitamin providing (this can range from offering either omega 3’s, monounsaturated fats, or natural saturated fats which can aid with satiety).
