Prepare the Dates: After soaking the dates to soften them, drain and set aside.
Process Dry Ingredients: In a food processor, combine the cashews, coconut flakes, oats, and flax seeds. Pulse until the mixture reaches a coarse, sand-like consistency.
Add Dates: Add the softened dates to the food processor with the dry mixture. Process until the dates are well incorporated, and the mixture starts to come together.
Incorporate Water: Pour in the ¼ cup of water and blend again until the mixture becomes sticky and holds together when pressed between your fingers.
Optional Add-Ins: If you're adding chocolate chips or M&M's, fold them into the mixture at this stage.
Form the Bars: Line a 9x9-inch dish with parchment paper, leaving some overhang for easy removal. Transfer the mixture into the dish and press it down firmly to create an even layer.
Chill: Place the dish in the refrigerator for about an hour to allow the mixture to firm up.
Cut into Bars: Once set, lift the mixture out of the dish using the parchment paper overhang and place it on a cutting board. Cut into rectangular bars of your desired size.
Optional Drizzle: For an extra touch, drizzle the bars with melted chocolate. Simply melt your preferred type of chocolate and use a spoon to drizzle it over the bars. Allow the chocolate to set before serving.
