Line an 8x4 or 9x5-inch loaf pan with parchment paper.
If your dates aren't soft, soak them in warm water for 5 to 10 minutes. Pat them dry before using.
**Date and Nut Layer:** In a food processor, combine the soft dates, coconut, walnuts, and salt. Pulse until the mixture sticks together when pinched.
**Creamy Lemon Layer:** In a high-speed blender, blend the cashews, coconut milk, maple syrup, lemon juice and zest, vanilla, and salt until smooth and creamy.
Press the date and nut mixture firmly into the prepared pan. Spread the creamy lemon layer on top and add sliced strawberries.
Freeze for 8 hours or overnight. Slice into bars. If they're too frozen, let them sit at room temperature before serving.
Enjoy these refreshing frozen bars all summer long!
