Peanut Butter + Dark Choc Slice

What says ‘I love you’ more than delicious baked treats? We are obsessed with this rich peanut butter slice, topped with dark chocolate! You can prepare this in advance for Valentine’s/Galentine's Day. Those you are treating will love it knowing it’s packed with nourishing cashews and fibre-dense oats, plus marine collagen!

Makes: 16 bars

For the base:

  • 1 cup (85g) rolled oats
  • 1 cup (140g) cashews
  • 2 tbsp maple syrup
  • 1 tbsp coconut oil
  • 1 tsp sea salt

For the filling:

  • 2 cup smooth peanut butter
  • ½ cup maple syrup
  • 2 tsp vanilla extract
  • 2 serves JSHealth Pure Marine Collagen 
  • ¼ cup hot water 

For the topping:

  • 150g (5.3oz) dark chocolate, melted
  • 1 tsp coconut oil


Line a small tin with baking paper; we used a 20cm by 20cm square tin. 

To make the base, combine the oats and cashews in a food processor. Blitz until a fine crumb forms. Add the remaining ingredients and process until the mixture comes together. Place the mixture into the tin and use your hands to firmly press the mixture into the base of the tin. Place in the freezer to set. 

To make the filling, place the ingredients into a food processor and blitz until the mixture is comes together. Evenly press the peanut butter filling on top of the base and flatten with a spoon or your hands. 

Pour the melted chocolate over the peanut butter layer, making sure to evenly cover the slice. 

Transfer the slice to the freezer to set for a minimum of 1 hour.  

Once set, remove from the freezer, slice into squares and serve. We like to serve ours with a sprinkle of sea salt on top. 

Keep any leftovers stored in the fridge for up to 1 week, or the freezer for up to 2 months.
