Ingredients

These wholesome ingredients create a chewy chocolate base topped with a creamy peanut caramel layer. Each one adds flavor, texture, or nutrition to the bars.

For the Bars

• Oat milk (150 ml) – binds the mixture and keeps it smooth
• Melted cacao butter (10 ml) – for richness and a hint of chocolate aroma

For the Peanut Caramel

• Oat milk (80 ml) – creates a silky base for the caramel layer
• Peanut flour (60 g) – thickens the caramel and adds nutty flavor
