Date bars are too sticky

I am making date bars very similar to nakd bars but keeping running into the same problem when making them.

The bars are way too sticky!

I used the following ingredients

• Dates
• Freeze dried raspberries
• Salt
• Vanilla extract

Anyone know what I am doing wrong? the taste is there but the texture is not.

The Nakd bars have a harder feel to them but I’m not sure how to get that. Ingredients and measurements are very similar too.
