Recipe Tips for Birthday Cake Protein Bars
Protein Options: Vegan Vanilla Protein Powder is the best protein for these birthday cake bars as it adds a touch of sweetness and texture. If you don’t have vanilla protein powder on hand, swap in your favourite flavoured protein powder.
Cashew Butter Alternatives: I like using cashew butter because of its neutral flavour, which works well in these protein bars. However, you can use any other nut or seed butter of your choice.
Make it nut free: Use tahini or any seed butter of your choice to make these bars nut free.
Store in the fridge for up to 7 days.
