protein mug cake


  • 1 scoop Impact Whey Protein (we used Sticky Toffee Pudding flavour, but you can use your favourite)
  • 1 egg white
  • ¼ tsp. baking powder
  • 1 tsp. sweetener
  • 2 tbsp. skimmed milk or almond milk
  • Sugar-Free Syrup (we used Butterscotch flavour)
  • 5 drops Flavdrops (we used Toffee flavour)
  • 1 heaped tsp. Cashew Butter for the centre (optional)


1. Mix all the dry ingredients in a mug with a fork until no lumps remain.

2. Add in the egg white and milk and mix until smooth.

3. Now's the time to drop in any extras for the middle – try a heaped tablespoon of your favourite nut butter.

4. Microwave for around 1 minute on high (give or take some time depending on your microwave). Keep an eye on it – if it starts to bubble over the top, stop microwaving and press the batter back into mug with a fork, then continue microwaving.

5. When finished, the cake should be cooked but still very moist. Now smother it in Sugar-Free Syrup. Yum!
