Start by lining your 9x9 inch baking dish with parchment paper. Leave some overhang on the sides to make it easier to lift out the bars later.
In your food processor, add the 1 cup of almonds and pulse until they are finely chopped but not turned into almond flour. You want some texture here!
Next, add the 1 1/3 cups of loosely packed dates and 1 cup of firmly packed dried apples to the food processor. Pulse until the mixture is well combined and sticky.
Add the 1 1/2 tablespoons of water and 3 tablespoons of melted almond butter (reserve 2 tablespoons for topping) to the processor. Blend until everything is evenly mixed and holds together when pressed between your fingers. If the mixture is too dry, add a little more water.
Sprinkle in the 1 teaspoon of cinnamon and pulse a few more times to incorporate the spice throughout the mixture.
Transfer the mixture into the prepared baking dish. Using a rubber spatula, press it down firmly and evenly across the bottom of the dish.
Drizzle the reserved 2 tablespoons of melted almond butter over the top of the bars. Sprinkle a bit of cinnamon and flaky sea salt for an extra touch of flavor.
Cover the dish with plastic wrap and refrigerate for at least 1 hour, or until the bars are firm enough to cut.
Once set, lift the bars out of the dish using the parchment paper overhang. Slice into squares or rectangles as desired and enjoy!
