Soak dates in boiling water for 5 minutes to soften. Drain water.
Process all ingredients in the food processor until they form a sticky, chunky texture. This could take 2 -4 minutes depending on your food processor and dates. Process until muxture reaches the consistency you're looking for. I like my slice to still have a little texture so I don't process until overly smooth. To test whether your slice is ready -pinch a little of the mixture together.It should stick together well. Add melted coconut oil if mixture is too dry.
Transfer your mixture to shallow bowl or baking dish lined with baking paper and press firmly into the dish.
OPTIONAL: press some choc chips onto the top of your slice
