Blend 1 cup of oats into a flour and mix with the other base ingredients. Divide into 24 and press down firmly into a mini muffin pan (or cases). Freeze whilst you make the caramel.
To make the caramel, blend the pitted dates and nut butter in a food processor. As you blend, add 1 tbsp of water to help the caramel come together. You may need one more tbsp, if your dates are harder. Once fully combined into a soft caramel, spread on top of the base. Freeze for about 30 minutes.
Finally, melt the chocolate in a bowl over a pan of hot water. Pour a spoonful onto the caramel and refrigerate until set.
