Preheat oven to 350 degrees. Line a 8x8 baking pan with parchment paper, leaving an overhang, then spray with coconut oil spray.
To a small saucepan, begin melting butter over low heat until light brown. Stir in minced dates and let cook until a medium brown butter is achieved. Set aside to cool while preparing blondie batter.
To a large bowl, add coconut sugar, cashew butter, egg and vanilla and whisk until well combined. With a spatula, add in cooled browned butter with dates and stir until well combined. To the wet mixture, add in almond flour, baking soda and salt. Combine well with a spatula. Stir in chocolate chips.
Transfer batter evenly to the prepared pan, smoothing top. Sprinkle with more chocolate chips then bake on the middle rack, for 18-20 minutes, until golden brown and just puffed in the middle. Let cool for 10 minutes then slice and serve.
Store leftovers in an airtight container in the fridge.
