In a bowl, add dates and soak them in hot water for 15-20 minutes.
Take a blender jar, add oats, almonds, walnuts and cocoa powder. Blend everything together until a coarse texture is achieved.
Now, add soaked dates and espresso in this mixture and blend again until it’s nicely combined.
Take small portions of the mixture and press them in sections of rectangular silicone tray. Ensure that you press the mixture firmly into each section, shaping it to fit the mould.
Place the silicone mould in the refrigerator and let it chill for at least 30 minutes or until the mixture sets and hold its shape.
Meanwhile, melt the dark chocolate and oil together in microwave.
Once set, carefully remove the bars from the silicone mould and dip them in melted dark chocolate and enjoy.
