Ingredients  

  • 250 g Rolled Oats
  • 60 g Protein Power whey or plant-based
  • 100 g Dates chopped
  • 50 g Almonds chopped
  • 100 g Peanut Butter crunchy is better here
  • 105 g Honey ~5 tbsp
  • 100 g Butter a plant alternative like Flora will work too
  • 150 ml Milk any plant alternative will work
  • 1 tsp Cinnamon
  • 1 pinch Salt (Optional) enhances the flavour, but go lightly!

Instructions 

  • Preheat your oven to 180 °C (fan) and line a baking tin with parchment paper. I used 25cm x 18cm, but anything around this size will work. Gather all your required ingredients.
  • In a small saucepan over low heat, melt the butter and honey together until smooth. Remove from heat and stir in the peanut butter and milk.
  • In a large mixing bowl, combine the oats, protein powder, chopped dates, chopped almonds, cinnamon, and salt. Mix well.
  • Pour the wet mixture over the dry ingredients. Mix thoroughly until all ingredients are evenly coated. The mixture should be sticky but manageable.
  • Transfer the mixture into the prepared baking tin. Press down firmly with a spatula or the back of a spoon to compact the mixture evenly.
  • Bake in the preheated oven for 20-25 minutes, or until the edges turn golden brown. The center may still feel slightly soft.
  • Remove from the oven and allow to cool in the tin for 10 minutes.
  • Lift the flapjack out using the parchment paper and place on a wire rack to cool completely.
  • Once cooled, cut into 12 bars (or desired number of pieces). Store in an airtight container at room temperature for up to 5 days, or in the fridge for up to 2 weeks.

Notes

  • As long as the weight ratios remain the same, you can play around with the recipe to suit your needs - dried cranberries instead of dates, or a mix of seeds instead of the almonds for extra crunch.
  • Try a teaspoon of cocoa powder instead of cinnamon for a chocolatey kick.
  • I used vanilla whey, but any protein flavour would work.
  • I didn't actually use honey in this, but my homemade dandelion syrup (a vegan honey alternative that I make every spring). It works exactly the same as honey though.
