Line a baking sheet with baking paper.
In a mixing bowl, mix together peanut butter and crushed rice crispies until combined. (If you prefer not using rice crispies just use the peanut butter).
Remove the pits from the Medjool dates and place them on a baking tray.
Use a pipe or spoon to stuff the dates with peanut butter in the center. Press the halves together and push a skewer into the end of the dates.
In a medium saucepan, combine syrup, vegan butter, and sugar and melt the sugar without bringing it to a boil. Once the sugar is melted bring to a boil and let the toffee cook until it’s a light caramel golden color.
Working quickly, remove the toffee from the heat. Carefully dip the skewered dates into the toffee making sure they are fully coated.
Place the dates on the lined baking tray and carefully remove the skewers from the dates.
Sprinkle with finely crushed sea salt while the toffee is still hot.Leave to cool completely. Serve and enjoy.
