Chocolate Brownie Weetbix Protein Slice

It's a mouthful to say and to enjoy! You don't have to be a baking master to whip up this insanely simple and delicious slice. Only 5 ingredients and no baking required. These are a snack that won't have you feeling too heavy. And if you're a fan of chocolate, this is a must try!




  • Remaining protein powder
  • 1 heaped tsp runny peanut butter
  • 3-4 tbsp water (runny enough to be a syrup and to cover the base)



  1. In a bowl, crumble your Weetbix finely.
  2. Mix through remaining ingredients and press down into a lined container or tray.
  3. For the icing, in a small dip bowl combine ingredients and whisk until smooth.
  4. If it’s too dry and not syrup like add more water. If it’s too wet, add more protein. 
  5. Pour on top of base and set in freezer.
