Mix together the oats, banana, Natvia, nut butter and milk and mix together to combine. Divide between a 6-hole muffin tin - press up the sides and on the bottom. Bake at 180C for 15 minutes until golden then leave to cool.
Once cooled, spoon ½ teaspoon of peanut butter on top of each base. Then divide a chocolate protein pudding on top to reach the top.
Sprinkle over some nuts on top and chill in the fridge for at least 2 hours then enjoy!
