Ingredients
Ingredient Notes
- Weetbix: I sued regular sanitarium weetbix, but you could also use gluten free weetbix, or the protein weetbix. Just make sure to use a plain flavour. Weetabix is the weetbix version if you’re in the UK or US.
- Dates: medjool dates are the best for this recipe as they are soft ands caramel like.
- Apricots: I recommend good quality dried apricots. My preferred brand is Angus Park.
- Protein Powder: Any chocolate protein powder will work. I used Genetix Nutrition Lean WPI Chocolate Bomb Flavour Protein Powder and I buy it from Nutrition Warehouse in Australia.
- Peanut Butter: I recommend sugar free peanut butter, or natural peanut butter. These are available from Coles and Woolworths in Australia.
I decided to make a weetbix slice with protein powder because I wanted a protein packed snack that I could have on hand. One that was going to fill me up and was yummy. Sure I could just have a protein shake, but this idea was so much more appealing, and it didn’t disappoint.
You can definitely taste the weetbix in this chocolate slice, buts its subtle, and I can’t even taste the protein powder. What I can taste, is nuttiness, chocolate, peanut butter and fruity sweetness.
Snacks that have protein powder in them:
- Keep you fuller for longer
- Help you to get your daily protein intake
- Are fun to eat
- Are portable
- And help to keep cravings at bay

I used a large loaf tin 28cm x 13cm. You could also use a square tin that is around 20cm x 20 cm.
This slice keeps for 1 week in the fridge. Make sure to store it in an air tight container.
Whilst I haven’t tried to freeze it (it all gets eaten within a week!), I wouldn’t recommend freezing it.
Yes. If you don’t want to use protein powder, leave it out, along with the water. The recipe will be just as good!
I love using a chocolate flavoured protein powder. I prefer to use Whey Protein Powders, and my favourite brands are Bare Blends and Genetix. For this recipe, I used Genetix Nutrition Lean WPI Chocolate Bomb Flavour Protein Powder. I would avoid using vanilla flavoured powder.
